Abstract
PURPOSE: To make it possible to combine together variations of the output voltage of a power circuit, by using the output of a frequency dividing circuit composed of a flip-flop as an input for varying the output voltage of the power circuit.
CONSTITUTION: Once signal input V0 is supplied, a waveform generated by clock oscillator 1 is applied to a frequency dividing circuit composed of FF's 3 and 4 via gate 2. Then if outputs of FF's 3 and 4 would arrive while signal input V0 is being applied, input signals are supplied from gates 5 and 6 to relay circuits 7 and 8. Further, resistances V3 and V6 of constant voltage supply 9 are shorted via relay contacts of relay circuits 7 and 8 to vary output voltages V1 and V2.
