Abstract

PURPOSE: To improve the stability and accuracy of control function of an engine revolving rate controller by employing a highly stable and highly accurate digital one-shot pulse generating circuit as means of pulse generation in an engine revolving rate controller.
CONSTITUTION: A one-shot pulse generating circuit comprises data type FF circuits 51W54. Each of the FF circuit 51W54 has functions of providing an input signal to a terminal D from the terminal Q in synchronism with the rising-up period of an input pulse to a CL terminal and of providing acting as a set-reset FF circuit when a signal "1" is applied to the terminal S or R. The one-shot pulse generating circuit comprises an up-down counter 55 of 4 bits which can be preset, and a clock pulse generator 62 including a crystal oscillator element 59. The counter 55 is adpated to provide a reset signal according to the rising-up of the first clock pulse after the count of the counter 55 has reached a predetermined count.
