摘要： PURPOSE:To easily widen a noise removal width and to improve reliability by sampling interruption input signals by clock signals for the plural number of times, inputting the input signals and the output of an oscillation stopping signal holding latch to a gate circuit and outputting the oscillation stopping signals. CONSTITUTION:A sampling circuit 10 performs sampling by the clock signals 7 by using three D flip-flops 11-13 for instance. Thus, the output 18 of the sampling circuit 10 can be asserted only when the sampled interruption input signals 2 are in an asserted state equal to or more than three times. The output 18 of the sampling circuit 10 is reset by the oscillation stopping signal holding latch 3, the output of the oscillation stopping signal holding latch 3 is inputted to the gate circuit 30 and the output of the gate circuit 30 is negated even after the interruption input signals 2 are negated. The output 33 of the gate circuit 30 is connected to the control input of an oscillation circuit 20 and the oscillation circuit 20 continues oscillation. Thus, the noise removal width can be easily and accurately extended and set.

摘要： PURPOSE:To prevent generation of gate noise by providing a diode between an oscillator circuit and a narrow-width pulse circuit and providing a resistance between a negative power source and the base of an oscillation transistor in the gate pulse generation circuit of a switching element such as a thyristor. CONSTITUTION:Wide-width signals are applied to terminal A to make transistor Tr1 conductive and operate oscillator circuit 2, and the oscillation output is subjected to full-wave rectification to obtain gate pulses at an output terminal. Since capacitor C1 is charged and discharged by transistor Tr1, circuit 3 generates narrow- width pulses. Here, diode Dd5 is provided for preventing noise from being generated from narrow-width pulse generation circuit 3 dependently upon discharge of capacitor C1 in case that the voltage of power source 1 is lowered, and resistances R6 and R7 are provided for preventing noise from being generated by the malfunction of oscillator circuit 2 dependently upon discharge of capacitor C1 in case that the voltage of the power source becomes high.
