摘要： A single-phase motor driving circuit includes a controller for outputting a control signal to drive a single-phase motor in a period in which a saw-tooth voltage of a predetermined cycle is larger than a duty setting voltage based on a result of comparing a detected temperature voltage changed based on a temperature detected by a temperature detecting device with a starting duty setting voltage increased with time while a voltage smaller than the detected temperature voltage at the time of starting the single-phase motor is set as an initial value. The controller sets the duty setting voltage as the starting duty setting voltage when the result of the comparison shows that the starting duty setting voltage is smaller than the detected temperature voltage, and the duty setting voltage as the detected temperature voltage when the starting duty setting voltage is larger than the detected temperature voltage.

摘要： To generate a drive wave for driving a piezo-actuator. Drive data concerning the number of drive waves supplied through a serial bus is stored in a drive data storage unit. A comparing circuit detects whether or not the number of drive waves have been generated, the number being specified by the drive data, and the drive wave keeps being generated until such detection is made.

摘要： Fundamental waveform data transferred through a serial interface is stored in a register. A fundamental waveform generation circuit uses the data to generate a fundamental waveform. A selector is capable of providing fundamental waveform data stored in a fixed memory to the register to replace the fundamental waveform data provided through the serial interface. An initial counter provides a low level signal to an exclusive OR gate until its count value reaches a first predetermined value. A direction control signal M/I is provided to the exclusive OR gate from an external source and the direction control signal M/I at high or low level inverts a direction control signal to be provided to a direction selector.
