    摘要： When a door locking operation is conducted in a vehicle, an in-vehicle device executes a vehicle compartment checking to check whether a mobile unit exists in the vehicle compartment. When the in-vehicle device receives a response from the mobile unit, the in-vehicle device transmits a search signal to the mobile unit, prohibits the door locking, and activates a buzzer, etc. The mobile unit can be prevented from being blocked in a vehicle compartment. When the mobile unit receives the search signal, it blows the buzzer, thereby making it possible to indicate the location of its existence.

    摘要： Two standard waves from a standard waveform generation circuit are output via an output gate while being interchanged by a direction selector. The switching operation of the direction selector is controlled by a direction control signal M/I. 200 cycles of the standard waveforms are counted up by a 200-cycle counter. A drive counter is downcounted every 200 cycles, while the drive counter is upcounted in accordance with the number of drive pulses DRIVE. When the count value of the drive counter becomes zero, output from the output gate is thereby stopped. At the time of startup, outputs from the 200-cycle counter are counted so as to output a drive wave in a predetermined number in a predetermined direction.
