A method (and apparatus) includes that a duty ratio of a driving voltage output to each wiper motor be required to be set according to several conditions. That is, while each wiper blade is moved in an interval from a starting position to a predetermined first wiping position in an upward operation, the duty ratio of a wiper motor on a driver's seat side is set so that the duty ratio is larger than the duty ratio of a wiper motor on a passenger seat side. Also, while each wiper blade is moved in another interval from each upper return position to a predetermined second wiping position in a return operation, the duty ratio of the wiper motor on the passenger seat side is set so that the duty ratio is larger than the duty ratio of the wiper motor on the driver's seat side.

Control method for wiper apparatus

An automatic car-speed controller is disclosed, which is provided with an actuator having a solenoid clutch comprising a sector wheel rotatable around a shaft and an output pulley rotatable independently from the sector wheel around the shaft coaxially. The sector wheel consists of a gear portion, a solenoid, and a sector arm alienating the solenoid from a rotational center thereof. The output pulley consists of a pulley portion attached with a throttle cable nearly to the rotational center, a magnetic body attracted by the solenoid of the sector wheel, and an arm connecting the magnetic body with the pulley portion.

Actuator and an automatic car-speed controller

An automatic speed control device for a vehicle or a stationary generator for emergency use is disclosed. The device comprises a speed signal detector means for generating speed pulses of a frequency proportional to a speed, a constant time generator means connected to the detector, a speed pulse counter means for counting the speed pulses received within the constant time, an auxiliary pulse generator means for generating auxiliary pulses of a constant period from the leading edge of each speed pulse, an auxiliary pulse counter means for counting from the leading edge of each speed pulse auxiliary pulse of constant period sufficiently smaller than a period of the speed pulse at the highest speed, an actual speed computing means connected to both counters for computing an actual speed from the counted result of speed pulses at the end of the constant time and the counted result of auxiliary pulse, a setting speed memory means connected to the actual speed computing means, a speed comparator means for comparing the actual speed and the setting thereby to generate an output signal corresponding to the difference thereof, and an electromechanical transducer means connected to receive the output signal of actual speed computing means for driving an adjustable speed mechanism of a prime mover.
