Title: Relay having arc detector
Inventor: RUISU ESU PORUSUTAA
IPC: H01H50/04
Filed: 1990-03-16
Abstract: PURPOSE: To control a relay by opening or closing a zero-current point in an AC load circuit with a relay connected to a load, and controlling an operating or dropout point so as to eliminate arc discharge in a relay contact. CONSTITUTION: A relay 42 and a detector 46 are connected to an AC circuit and a control circuit respectively, in order to minimize relay arc discharge by operating a relay 42 so as to open or close the contact in a zero-current point in the AC circuit. That is, the control circuit receives an instruction signal, inspects its memory, sends an operation signal to the relay to operate the relay 42 by opening or closing the contact in the zero-current point. When a load is switched to on or off, the relay for supplying an AC load is controlled, so as to minimize arc discharge in the relay contact and maximize the life time of the relay.

Title: Timing generator
Inventor: HAYASHI YOSHIHIKO
IPC: G06F1/06
Filed: 1982-04-23
Abstract: PURPOSE:To generate a high-precision, high-stability timing signal which has resolution more than a period determined by the operation speed of a counter, by performing phase control over a clock to be supplied to the counter. CONSTITUTION:Output signals 34a, 34b, and 34c of latches contain information on a phase difference between the clock to be supplied to the counter and a clock for generating the timing signal. The output 19 of a frequency divider is supplied to the counter and when the outputs 34a, 34b, and 34c have a phase difference ''3'' or ''4'', an OR gate 46 outputs ''1'' to select a delay line 40. Therefore, a control signal 35 is ''0'' during a period determined by the delay line 40, ''1'' during a period determined by a delay line 45, and ''0'' thereafter. Consequently, an output 22 or 23 having the phase difference ''3'' or ''4'' from the output 19 is passed through an AND gate 18 to obtain a timing generation signal 25.
