Abstract

PURPOSE:To secure the same duty as well as to prevent the chattering of the switch by giving the instantaneous charging to the oscillation capacitor via the trigger application means to secure the oscillation with a fixed time. CONSTITUTION:Diode 6, inverter 7, R8, power voltage +B and switch 9 are added to the multivibrator consisting of 1st and 2nd NAND circuits 1 and 2, oscillation capacitor C3 plus resistance 4 and 5. As a result, a free running multivibrator, which is capable of retriggering by having oscillation with a fixed time even with application of the trigger at any moment during oscillation, can be obtained. With application of trigger (B) through ON/OFF of switch 9, the output of inverter 7 is charged (C) instantaneously by C3 via diode 6. Thus the voltage of waveform (A) can be obtained at output terminal 10 to secure the time.
