Abstract

PURPOSE:To improve reliability by suppressing an error output in a short time by applying a timer circuit with clock pulses higher in frequency that normal clock pulses when electric power supply is broken. CONSTITUTION:In normal operation, after the counter is reset by information input signal G, output signal F is generated as long time as clock pulses D are counted to a fixed value. If instantaneous break H of the electric power supply occurs, the instantaneous-break detecting circuit charges clock pulses to the counter over to high- frequency clock pulses E. Consequently, even if output signal F is generated by mistake, output signal F can recover in a short time by counting high-frequency clock pulses E.
