It's

just

what

you've

come

to

expect

from

Hitachi,

one

of

the

most

experienced manufacturers

of high-

head

pump-turbines

and

the

first

to offer the 500

m

head

reversible

type. To date,

we've

installed

or

begun

construction

on

41

high-head

pump-turbines

in

13

different

projects

for

a combined

total

output

of 11

,250

MW.

Now

we've

successfu

lly-

completed

development

of the

1,000

m

head

double stage

prototype.

This

ultrahigh-head

reversible

pump-turbine

features

movable

wicket

gates

for

both the

upper

and

lower

stages. lt's

capable

of regulating

power

output

just

like

a single

stage

reversible

pump-turbine,

but with

shal lower

su bmergence.

For

the best

results in

large

capacity

electric

power

generation,

trust

Hitachi's

expertise

-

proven

leadership

and reliability in

pumped

storage

power

plant

equipment.

DIGITAL

EARTHQUAKE

RECORDING DEVICE

2.

Block

Diagram

Senser

This dJvice

is

a digital

earthquake

recording

device, has

an

all-in-one

configuration

and

uses sensers

of the

feedb,ack

type to

detect

the

acceleration

component

of

earthqurake

movement

and

other

forms

of

vibration

and to

record them

on magnetic

tape.

Accordingly,

the connection

of

this device

to the

sens-

ers

manufactured

by

this company,

ffid

the suppll'

of

power will

enable

it

to

function

as

a measuring

device-

The

configuration

of

the

system

comprises

the sitart

control

part

which

sets the device

in

motion

upon the

gen-

eration

of an

earthquake,

the

data

delay

part

for the record-

ing

of

the earthquake

motion

before

the start,

the auton:ntic

corrector

for correction

of

the

recorded

waveform,

the iligi-

tal

clock

part for

recording

the

time

at the

beginninjg

of

operation

of

the

devi@,

an

FM

receiver

for correction

of

the digital

clock

and the

data

control

part

which controls

the digital

magnetic

taPe.

Magnetic

tape

which

has been

recorded in

this

manner

is

removed

from

the

device

for

high-speed

processing by

computer.

Futhermore,

this

device

has a

simultaneous

an.alog

monitor

when

recording,

and

enables

analog

monitoring

through reproduction

D/A

conversion.

ln order to do

this,

the device

is

provided

with

a

signal

selector

and a

visigraph

(optical-type recording

device)

for

waveform recording.

In

addition,

it is

provided

with

a

fail'safe

power

devic,e

to

guarantee

records

in times

of

power failure.

Civil

Trans-

ducers

are

different

in

that

they use

performance-proven

Kyowa

gages

as

sensing

elements.

Peripheral

with

instrument,

allow-

ing

more

inexpensive

than

by

conventional

types.

And

the

indicator

for

use with

these

employs

a unique

cir-

cuit

developed

by

Kyowa

and

eliminates

the need

for

correction

for up

5

km

extension

to

save

time and labor.

The

adding

of

it to a
