Abstract

PURPOSE:To economically execute the sequence of turning on and off of a few channels, by turning on and off regulating circuits by use of output signals of time constant circuits which are controlled by a switch at the same time. CONSTITUTION:When a flip-flop 1 is set by a switch, output of buffers 2a, 2b become a high level, and each input voltage v1, v2 of comparators 4a, 4b rises by a time constant decided by capacitors C1, C2 and a resistance group, respectively. The comparators generate outputs when the input voltage exceeds set voltage V1 or V2, and driving regulator circuits CH#1, CH#2, respectively. When the flip- flop is reset by the switch, the capacitors are discharged, and the regulator circuits are turned off after the time decided by the respective time constants. The turn-on and off time is set freely by the time constant and the set voltage.
