1. Introduction
All the elements necessary for the hybrid computation such as comparators, including
electronic switches, servo-set potentiometers, servo-set function generators, etc., have
been provided to apply HITACIIT 505 Analog Computer to the hybrid computation system.
This literature deals only with the tunctions of HITACHI 505 (hereinafter called 505) in re-
ference to hybrid computation capabilities. For detailed descriptions of the hybrid linkage,
a separate literature is provided,
Some of the electronic spuvcitications and/or physical structures described in this
literature may be Subject to preliminary change without notification at the convenience of
manufacturing.
2. Configurations and Functions
2.1. Functions as the hybrid computing system
(1) Capability of being connected with A-D converter and D-A converter, 505 is designed
to be able to accept maximum eight (8) channels of inputs and outputs of A-D converter
and D-A converter respectively through Trunk Line Panel TR-151. Analog output signal
voltage to be transferred to A-D converter from 303 is Limited within +100V, while
analog input signal voltage to be received from D-A converter is within either +100V
or +10V.

Capability of reading out D-C amplifiers and comparators outputs.
Outputs of each D-C amplifier and comparator are capable to be directly read out by
the linkage because they, quite individually, have a relay system for their own output
selection. Accordingly, the control signal of +24V, 30 mA for each relay must be
provided by the linkage for the automatic read out. However, to read out all of the
outputs of amplifiers automatically is not supposed to be necessary anyhow, because
some of D-C amplifiers combined to non-linear elements of 505 are not necessarily
read out. Usually, outputs signals of D-C amplifiers are read out through A-D con-
verter by means of patch connection, if the read-out is required. Automatic output
selector is optional and is not described in this literature.

(5) Hybrid linkage controls 505's control mode.
All the control modes of 505 such as RESET, COMPUTE, HOLD,POT-SET, ALL-
RESET and REP-OPE can be controlled by an external control signal specified as
follows:
Rise time ON +5V to +8V
less than 10yus NN
OFF OFF OV or within +0.5 V
@ More than 1 ms in case of RESET, COMPUTE and HOLD
@ More than 10 ms in case of POT-SET and ALL-RESET

Related to SFG-251
One each input line and one each output line for each SFG-251 are connected to the
patch board through TR-151. Therefore, 1 ea connection cable between CS-505C and
Servo-set Console is necessary at customer's expense.
Modification on 2nd Computing Console
In case that 505 has two each of CS-505C, two each of TR-151 which is provided to
each CS-505C are occupied for the signai between one CS-505C and the other
CS-505C, Accordingly, transmission in such case, additional TR-131 (3 each alto-
altogether) must be mounted into the section to which normally MC-151 is mounted
Additional external connector of 50 pins for additional TR-151 is provided at
customer's expense.
