Abstract

PURPOSE:To prevent the breakdown of the component parts of the like of the circuit to which the pulse signal is supplied, by applying the pulse signal to the differentiating circuit having the different time constants at the discharging and charging time each and then limiting both the pulse duration and the duty ratio down to the prescribed levels or less. CONSTITUTION:The parallel circuit of resistor 4 and diode 6 is connected in series to capacitor 3, and the other end of resistane 5 one end of which is connected to the output side of the parallel circuit is earthed. Thus a differential circuit having the different time constants at the charging and discharging time each is formed. And then the ratio between the time exceeding the potential of the fixed threshold level at output terminal 2 and the time exceeding the potential of the fixed threshold level to the fixed cycle is set to the level under the prescribed pulse duration and the prescribed duty ratio each. As a result, the breakdown can be prevented for the component parts or the like of the circuit to which the pulse signal is supplied.
