Abstract

PURPOSE:To set a time limit accurately by each forming a digital timer, which sets a time limit sufficiently longer than the period of commercial AC voltage, to a logic circuit section and a timer, which sets a time limit sufficiently shorter than the period of AC voltage, to a linear circuit section. CONSTITUTION:The bipolar semiconductor integrated circuit 1 of a single chip used for a controller for an electronic sewing machine has the linear circuit section 21 consisting of an ignition controlling section 15 with the timer 18 for setting pulse width and a source synchronous signal generating section 19 and th logic circuit section 33 consisting of the counter 31 counting source synchronous signals and a drive control command generating section 32. The timer 18 for setting pulse width is the charge and discharge type timer with a resistor and a capacitor, and sets the time limit sufficiently shorter than the period of source voltage, and the timer composed of the counter 31 sets the time limit sufficiently longer than the period of source voltage, and sets it accurately.
