    摘要: A rotation sensing system includes a rotation sensor for outputting sinusoidal pulses, a waveform shaping circuit for shaping each of the sinusoidal pulses into a rectangular pulse, and a microcomputer for receiving an output of the waveform shaping circuit. In the microcomputer, the rectangular pulse appearing in the output of the waveform shaping circuit is processed so as to obtain information on the rotation of an object to be sensed, and also a malfunction of the rotation sensor is detected. Namely, when the rectangular pulse is not inputted into the microcomputer during a set time period, and at the same time when the level of the output of the waveform shaping circuit is equal to the level of the rectangular pulse, the microcomputer produces a signal representative of the malfunction of the rotation sensor.

    摘要: A driving circuit for use in controlling a motor for controlling an air mixing door, an inner and surrounding air change-over door and a mode setting door and the like used in a vehicle air conditioning device, or a motor used in opening or closing of window panes of a vehicle or in opening or closing the door which includes a control transistor for use in controlling a transistor circuit having a transistor to cause both normal and reverse directed currents to flow in a vehicle motor, the control transistor being operated until a specified period of time has elapsed after the power supply switch is turned on, the motor input being shut off by the control transistor so as to prevent erroneous operation of the motor just after the power supply switch is turned on or to prevent the production of a chattering sound caused by the operation of gear trains with the motor. The control transistor is operated with a charging voltage in a capacitor for sensing a load of the motor, the motor input is shut off when an excessive load is applied to the motor, the shut-off condition of the motor input is maintained by a self-holding transistor, an electric load in the capacitor is discharged through the control transistor when the motor is stopped, the shut-off condition of the motor input is not continued with the remaining electric load of the capacitor, whereby the stationary motor may subsequently be driven.
