摘要： PURPOSE:To increase the reliability of the path selection relay by discharging the charge stored to the driving cable via the resistance and then eliminating the working action of the relay contact. CONSTITUTION:Channel driving unit 1 and channel unit 2 are connected each other via driving cable 5 and 6. And driving gate switch 3 and 4 plus driving source 11 are provided to unit 1, and unit 2 contains load 8 and path selection relay contact 7. Then resistance 12 is connected to cable 6, and the resistance value is increased up to such level that no effect is given to the driving current and that is small enough compared with the off-resistance of switch 4. As a result, the potential which is deleted through cable 6 when switch 3 and 4 plus contact 7 have no action becomes nearly identical to the earth, and thus floating capacity 10 is discharged, eliminating the working action of contact 7. Thus, the reliability can be enhanced for the relay.

摘要： PURPOSE:To make it possible to detect the fault of a data generating circuit by providing two data generating circuits and by using the output of one circuit for data to a controlled unit and the other for input information to a parity-bit generator. CONSTITUTION:As data generating circuits, unit-number decoders 1 and 1' are provided; when the output of decoder 1 generating unit number ''2'' as input information of unit-number collating circuit 6 inside the controlled unit is supposed to get into stack trouble, information different from that of decoder 1 in the stack trouble can be obtained since decoder 1' generating information inputted to parity- bit generator 4 is normal. As a result, the check result of collating circuit 6 of the controlled unit becomes ''error'' . In addition, the output of decoder 1' is also ''error'' in case of the stack trouble, thereby detecting the trouble of the data generating circuit.
