    摘要: An object detector capable of reliably detecting objects around a vehicle is mounted on a wall of a bumper of a vehicle. Thicknesses of the bumper and of a bottom surface portion of a housing are less than one-half the wavelength of ultrasonic waves generated by a piezoelectric vibrator. This suppresses the reflection of ultrasonic waves by the bumper and by the bottom surface portion of the housing, and enhances the ultrasonic wave propagation efficiency, making it possible to reliably detect objects positioned around the vehicle.

    摘要: An ultrasonic sensor includes an inner case mainly made of plastic and having a shape of a cylinder with a bottom portion. A conductive film is attached to the bottom portion. An electrode formed at a surface of the piezoelectric vibrator is attached to the conductive film to be electrically connected with the conductive film. Therefore, by connecting leads with the conductive film and another electrode at the other side of the piezoelectric vibrator, the electric conduction between an external circuit and both electrodes at both surfaces of the piezoelectric vibrator is ensured.

    摘要: An ultrasonic sensor includes a piezoelectric vibrator, a reverberation measuring device and a compensating device. The piezoelectric vibrator vibrates to transmit an ultrasonic wave, receives a reflected wave of the transmitted ultrasonic wave and produces an output signal corresponding to vibration of the piezoelectric vibrator. The reverberation measuring device measures a reverberation period of the piezoelectric vibrator from the output signal. The compensating device compensates for an operation characteristic of the piezoelectric vibrator in accordance with the measured reverberation period. Thus, the ultrasonic sensor can decrease a reverberation period, which may cause reduction in detection accuracy and impossibility of detection of an obstacle at a short distance.

    摘要: A location detection apparatus is disclosed that includes: a light source; a light output side reflector having a reflecting surface for reflecting light from the light source to a space; a rotation mechanism for rotating the light output side reflector; a first light receiving element for receiving the light reflected from an object existing in the space; a light reception side reflector for reflecting the light from the object to the first light receiving element; a second light receiving element for receiving the light from the light output side reflector; a light conductor for conducting the light reflected from or transmitted through the reflecting surface toward the second light receiving element when the light output side reflector is in a predetermined position; and a rotational position detector that detects rotational position of the light output side reflector based on a detection result of the second light receiving element.

    摘要: An electromagnetic relay switches to conduct and interrupt currents having different magnitudes and flowing though mutually opposite paths via the electromagnetic relay. The relay includes a coil generating a magnetic force and a pair of contact sections opened and closed selectively by the magnetic force. The contact sections comprise a pair of fixed contacts and a pair of movable contacts. Each fixed contacts is held by a pair of conductive fixed holders and is near a tip section of each fixed holder. The movable contacts are fixed to a conductive movable holder and moves toward and away from the fixed holders selectively in response to the magnetic force. The relay further includes two arc-extinguishing magnet members adjacent to the contact sections such that, the arc generated by interrupting one current having a magnitude larger than the other current is extended toward the tip section at each contact section.
