Abstract

PURPOSE: To facilitate an easy alteration of the timer set time by using the pulse voltage obtained by rectifying the commercial power surce for the power voltage of the oscillation circuit the oscillation frequency of which is made variable and then using the output signal of the oscillation circuit for the time reference signal of the timer respectively.
CONSTITUTION: The full-wave rectification is given to commercial power source AC via diode bridge D, and the full-wave rectification voltage is used for the power voltage of oscillation circuit 1 consisting of the multivibrator the oscillation frequency of which is made variable. Then the output of circuit 1 receives the pulse amplification via transistor T3 and then supplied to counter circuit 2, and load control relay Ry is controlled with the output of circuit 2. Circuit 1 starts oscillation with the frequency which is decided by resistances R4 and R5 plus capacitors C2 and C3 and when the full-wave rectification voltage becomes higher than the working voltage of the multivibrator, thus generating the group pulse synchronized with power source AC. The pulse number occurring within the half cycle of power source AC can be set freely by making one of R4 and R5 variable. Thus the alteration can be facilitated for the set time of the timer.
