High

voltages from

hundreds

volts

to tens

of

thousands volts are

to

be applied

to

the

electronic

equipment

such radio

and radar

devices.

You do not

face

any danger during

normal operation,

but

sufJicient

cares are

required for maintenance,

inspection

and adjustment

of their internal

components.

(Maintenance,

check-up

and adjustment of the

inside

of

the

equipment

are

prohibited

except

by maintenance specialists.

)

High

voltages o{

tens

of thousands volts

are

so

dangerous as

to bring

an

instantaneous death

from

electric shock, but

even

voltages

of

hundred

volts may sometimes

lead to a death

from

electric

shock.

To

prevenl

such an accident,

make

it

a

rule to turn off

the

power

switch, discharge

capacitors

with a wire

surely earthed on

an end

and make

sure

that

internal

parts

are no longer

charged

before

you

touch

any

parb

inside

these devices.

At the time,

wearing

dry cotton

gloves

ensures

you

further to

prevent

such

danger.

lt is also a

necessary

caution

to

put

one of

your

hands

in

the

pocket

and

not to use

your

both

hands

at

the

same time.

It is also

important to selecl

a stable

foothold

always lo

prevent

additional injuries once

you

were

shocked

by electricity.

lf

you

were

injured

from

electric shock,

disinfect the burn sufiiciently

and

get

it

taken care

of

promPtly.

When

finding

a victim

of

electric shock, tum

off

the

power

source and earth the circuit

immediately.

lf it

is

impossible

to

turn

off

the circuit,

move the

victim away

promptly

using

insulators

such as dry

wood

plate

and

cloth without touching

the

victim

directly.

In case

of electric

shock,

breathing may

stop suddenly if cunent

flows

lo the

respiration

center

in

the

brain.

lf the shock is

notso strong, artificial

respiration may

recover

breathing.

When

shocked

by

electricity,

the victim

will come

to

look

very

bad with weak

pulse

or withoul

beating, resulting

in

unconsciousness

and

rigidity.

-t-

*

First-aid

treatments

As far

as

the victim of electric shock

is

not in

dangerous

condition,

do not move

him

and

practice

artificial

respiration on him immediately.

Once

started,

it

should

be continued rhythmically"

(1)

Do

not touch

the victim

confugedly

as

result

of the accident,

but rescuer may

also

get

an

electric

shock.

(2)

Turn off the

power

source calmly

and move the victim away

quietly

from the electric line.

(3)

Call

a

physician

or ambulance immediately

or ask someone

to call a doctor.

(4)

Lay

the victim

on his back and loosen

his

necktie,

clothes,

belt,

etc.

(5)

a

.Examine

the

victim's

pulse

b.Examine

his

heartbeat

bringing

your

ear

close to his

heart.

c .Examine

his breathing bringing

the

back of

your

hand or

your

face close

to his face.

d .Check the

size of the

pupils

of

his

eyes.

(6)

Open

the

victim's mouth

and

take

out artificial teeth, cigarette

or chewing

gum

if

any.

Keep

his mouth

open, stretch

his

tongue

and insert

a towel

or the

like in his mouth to

prevent

the

tongue

from suffocating.

(lf

it is

hard to

open his mouth

due to set teeth, open it

with

a

screwdriver

and

insert

a towel in

this

mouth.)

(7)

Then,

wipe his

mouth

so that foaming

mucus does not accumulate

inside.

Mouth-to-mouth

respi ration

Tilt

the victim's head back

as

fat

as this face

looks

back.

(A pillow

may be inserted his neck.)

Push his

jaw

upward

to open

his throat wide

(to

spread

his airway).

Pinch the

victim's nostrils and take

a

deep

breath, block

his

mouth

completely

with

yours

and

blow

into his mouth

strongly. Take a

deep

breath again and

blow into

his

mouth.

Continue

this

10 to 15

times

a

minute

(blocking

his nostrils).

Carefulty

watch that

he has recovered

his

natural

breathing and

practicing

artificial

respiration.
lf

it is

difficutt to open

the victim's

mouth,

insert

a rubber or

vinyl tube

into

one

of his nostrils

and

blow

into

it blocking

the other

nostril and

his

mouth completely.

When

the

victim

recovers

consciousness,

he

may try

to

stand up suddenly,

but let him

lie

calmly

and serve him with a

cup

of

hot cofiee or

tea and keep

him warm and

quiet.

(Never

give

him alcoholic drinks.)

(4)

Method

of

mouth-to-mouth

respiration

by

raising

head

(1)

Raise

the

victim's

head. Support

his

forehead with one of

your

hand

and his

neck

with the other
hand.-O
When

you

tilt

his

head backward,

the

victim,

in most

cases,

opens

his

mouth

to the

air.

This makes

mouth-to-mouth

respiration easy.

(2)

Cover

his mouth

as

widely as

possible

with

yours

and

press

your

cheek

against

his

nose*@

Or,

pinch

pulse

and breathing

have stopped

r.

Cardiac massage

When

no

pulse

has

come

not

to be

felt, his

pupils

are

open

and no heartbeat

is heard,

cardiac

arrest is supposed

to have occurred

and artificial

respiration must be

performed.

(

1 ) Place

your

both

hands, one

hand on

the

other,

on

the lower

one third

area

of his

breastbone

and

compress

weight on his

breast

so that it is dented

about

2

cm

(Repeat

compressing

his beast 50

times or so a

minute).

(Cardiac

massage)

(

2 ) In case

of one

rescuer,

Repeat

cardiac massages

about

15 times and

blow into

his

mouth

2 times

quickly,

and

repeat

his combination.

ln

case

of two rescuers,

One

person

repeats cardiac

massages 15 times

while

the other

person

blow

into

his

moulh

once, and they shall

repeal his combination.

(Perform

the cardiac

massage and

mouth-lo-mouth

respiration)

(

3 ) Examine

his

pupils

and

his

pulse

sometimes.

When

the

both

have

returned

to normal,

stop

the artificial

respiration, serve

him with

a cup

of

hot cofiee or tea and

keep him

warm

and calm while

watching

him

carefully.

Commit

the victim

to a medical specialist

depending

on his condition.

(Never

give

him alcoholic drinks.)

To let

him

recover

from

the

mental shock,

it is necessary

for

persons

concerned

to understand

his situations

and

the

necessary treatments.

unit and a

23.1-inch color raster-scan

LCD

display unit

This radar

complies

with

the current

performance

standards of the

lMO.

I Functions

of This

System

The

JMA-9900

ARPA

series

is a color radar system

designed

to comply

with the

international standards

of

the lMO. The

main functions

include;

sea clutter

and

rein/snow clutter

suppression,

sensitivity adjustment,

interference

reflector,

bearing

and

range measurement

using

a trackball, fixed/variable

range

makers,

and

electronic

bearing

line, and

ARPA

functions

(automatic/manual

tiarget

acquisition

and

tracking,

vector and trail displays,

alarm

displays and trial

maneuvering).

In addition,

the equipment

has

the functions

of

color

display setting

(4

views), own track

display,

NAV line and

marker

displays, TM

(True

Motion)

presentation,

Self-diagnostic

facilities. and

radar.

In

addition,

a

radar

switching

function

(lnterSwitch)

can

be

added

to switch between

two,

four

or eight

radar

units.

However, in order to this

function

for four

or eight

units,

an

external switching

box

is necessary.

f ARPA Functions

The ARPA functions

that

the

JMA-9900 series

incorporates will

be

outlined below.

I

I

]

First Stage :

Target Detection

from Radar

Information

This work corresponds

to

plotting

targets

by

band on

the radar display. Assume

that

a

ship is approaching

the

own ship.

You

can catch

the

ship on the

radar. Signals

from the

ship are

processed

with

the

data

processor

and

are

transferred to the

computer

as

signals of bearing

and

arrange

related to the own ship.

ln this

stage,

the system

has the

functions to

quantization

of

radar information, to

reject noises, to

eliminate

any

information other than

ship

information and

to

transfer necessary

position

data

of ships

to

the

computer.

I

II

]

Second Stage

: Target

Tracking

Targets are

plotted

at

intervals of 3 to 6 minutes

with the

radar, but tracking on

this

system is to

plot

them

electrically at

intervals of fixed

times.

This

means to compare

target

position

data to

be

detected

every

moment with

those

detected

previously

changes of

position

data

of the

target.

[IIIJ

Third

Stage

: Judgment

of

Existence of Ship

in Danger of

Collision

In this stage,

the system

calculates

speed

and

@urses of a target ship

from

ever-changing

position

data

of the target ship obtained

in

the

previous

stage

so as

to

judge

existence

of any

danger

of

collision.

After the calculation,

the system

can

easily

calculate the

Closest

Point of

Approach

(CPA)

to the own ship

and

the time required

to

reach the CPA

(TCPA

=

Time

to CPA). Both the CPA

and the

TCPA

are compared

with

the

preset

values

previously

set

previously

set

according to

the situations

of

the

own

ship so as

to

judge

existence

of any danger

of

collision.

1-1

aaaaaaaaaoaaaaaaoaaaaaaaaaaaoaaaaaoaaaa

[Ml

Fourth Stage :

lndication

The

above information must

be informed to

the

officer

maneuvering

the

own

ship. A

variety of

indicating

methods are available

including

LCD

display and numerical

indicator, and

various data

are

available.

This system

indicates unprocessed video, vectors

(to

be selected

from true vector and

relative

vector)

of other ships

and identification makes of danger

ship or safe

ship for

these

ships on the usual radarscope.

When

the target ship

is danger

one, the system

will sound an

alarm

and turns

on the alarm

lamp to alert the

officer.

FEATURES

Target Detection

by Latest Signal

Processing Technology

The system

employs

the

latest

adaptive clutter

suppression technology

to

eliminate

undesired

clutter

from

the

radar

video

signals that are

obtained

form

the

receiver with

a wide

dynamic range,

thus improving

the target detection.

Key Arrangement

for

Higher

Operability

The

basic

and

main functions

of the radar

can be

operated with the

minimum

necessary

keys,

ensuring

quick

action even

in

case of emergency.

Other

various useful

functions

are

also available

by the

use of the

soft button

on

and

gcreen

menu.

In

the

case

that two

or

more

operators operate the

radar equipment,

each

operator can

register

the

operating conditions

that are most favorable

to him/her

and

can be recalled

and

sel momentarily

(Personal

code

funclion

is built-in).

Advanced Technology

COLLISION

AVOIDANCE

Problems

of GollisionAvoidance

in

Navigation'

' ' ' ' ' '

Marine collision avoidance

is

one of the

problems

that have been recognized

from

of

old. Now, il will

be

described

briefly who the collision

avoidance

is

positioned

among

the

navigational aid

problems.

The navigation

pattern

of all mobile craft constitutes a system

with some closed

loops

regardless of

the media through

which

the

mobile craft travels,

whether

air, water, the

boundary between air

and

with another mobile

craft

and the

other is a loop

of funding a

right

and safe

way to

reach a

predestinate

destination.

Fi9.1.19 shows

the conceptual diagram of

navigation

pattern

by MR.E.W.Anderson.

The

closed

loop of collision

avoidance is shown

on the

left side

and closed

loop

of

finding a right

course

on the right side.

Maring

Accidgnts and Gollisiolls"

..

"

r

r r r r

" " "' r "

Among marine

accidents, collision accidents have

been highlighted as the tonnages

and speed of ships

become

higher

along

with

the increase

in traffic

at sea.

lf a tanker

carrying dangerous

articles

such

as crude oil collides

with

any other vessel, then

not

only the vessels

involved

with the accident but other

vessels

in the vicinity,

port

facilities,

inhabitants in

the

coasial

area as

well

as marine

resources

may

also

suffer

immeasurable damages

and lroubles.

Collision accidents

have

a high

percentage

of the

marine accidents

that

have occuned in recent

years.

To

cope

with

these

problems,

any

effective

measures are

needed

and some equipment

to achieve

collision avoidance

requirements have

been

developed at rapid strides.

vector

of

other ship for

prediction

and

the

true

veclor

of

for

collision

avoidance

in order

to

grasp

other

ship's aspect.

The relationship

between

the relative

vector

and

true

vector

is shown

in

Fig.1 .21

.

Both

rough

CPA

and TCPA can

be

obtained

easily

from

the

relative

speed

vector of

other

ship. This

method has an

advantage that

the risks

of

collision with

all

other ship

can

easily be

obtained

from

its

true

speed

vector,

enabling

other

ship's

aspect to be

seen

at

a

glance. Thus, the aspects of

other ships

(transverse,

out sail,

parallel

run,

reverse

run, etc.)

as

described

in the Act of Prevention

of Collision

at Sea

can be readily

grasped.

lf there

is

a

risk of

collision

with

other

ship, the

operator can

determine

which

rule

to be applied

and how

to operate

own ship.

Basic Goncept

of

Collision

Avoidancg" "

r'' r

"'

r r r''

There

are

two

aspects in

collision

avoidance: collision

prediction

and avoidance.

Collision

prediction

is

to

predict

that two or

more vessels

will

happen

io occupy

the

same

point

at the

same time,

while collision

avoidance is

to maneuver

vessels not to

occupy

the

same

point

at the same

time.

In

practical

operation

of

vessels, a spot

of collision

has to

be deemed to be a single

point

but a closed

zone. The closed

zone

is

conceptually

defined

as CPA

(Closest

Point

of

Approach). ln

collision

prediction,

the time to be

taken

until

a ship reaches

the

CPA

is

defined

as a TCPA

(Time

of CPA).

called

"Collision

Radar

is

still

playing

an

important

roll for

collision

prevention

and

positioning.

A

plotter

is

used to

further enhance

the radar functionality. The

plotter

is capable

of

plotting

other

positions

of other

ships

in

3 to 6 minute intervals

to monitor

their movements. The

plots

of other ships

represent their tracks relative to own ship,

and

it is shown whether

there

is a there is a

risk

of collision, namely

CPA and

TCPA can

be obtained. This method

using

a

plotter

is

fairly effective,

but the number of target

ships, which

are

manually

plotted,

is limited and

it

takes several minutes to measure those

PREPARATION

Tuning

[TUNE]

This

control

is

used

to tune

the

receiver.

lf

the

receiver is

detuned

from the best

level, the receiving

sensitivity

falls, and the targets on a long

range

or

the small targets on a short

range may be

overlooked.

In manual

tuning, rotate the

IIUNE]

control clockwise or anticlockwise and adjust so that

the

target

echoes are

the clearest. lf no suitable target

is

present,

adjust

the control

so

that the

tuning

indicator

bar

graph

at the upper

left of the

radar

display is maximized.

After

setting the radar

to

the

TRANSMIT mode,

it

take about

10 minutes until the oscillation

frequency of the magnetron is stabilized.

Therefore,

tune

the receiver once again after about 10
minutes.
For

automatic

tuning, set

"TUNE"

to

"ON"

in the

AUTO Menu.

(Refer

to

page

3-8).

Sensitivity Gontrol

IGAINI

This

is

used

to control

receiving sensitivity.

Clockwise

rotation

of

the

obseryation range.

lf the

sensitivity

is

too

high,

the

receiver

noise will increase

to reduce the

contrast

of the targets

with

the

background video

and make the targets obscure

on

the display.

To

observe densely crowded targets

or

the

targets on a short

range,

rotate the

[GAIN]

control

anticlockwise

to reduce the

sensitivity

so that the

tiargeis

are easy to

observe.

Be careful not to
