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： In an ultrasonic transceiver, an inner housing has a bottom portion, a first tubular side wall extending from one end surface of the bottom portion and a first flange portion formed on an outer peripheral portion of the first tubular side wall. The bottom portion and first tubular side wall provide a tubular cavity formed therebetween, and the piezoelectric member is mounted on the one end surface of the bottom portion in the tubular cavity. An outer housing has a second tubular side wall coaxially arranged around the outer peripheral portion of the first tubular side wall with a predetermined gap therebetween. The second tubular side wall is provided with one end portion which is opposite to one end surface of the first flange portion and contacted thereto. A first absorption member is inserted in the gap between the first tubular side wall and the second tubular side wall.

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 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 a transmitting device, a receiving device, and a circuit device. The circuit device determines that the receiving device receives an ultrasonic wave reflected from an object, when an output voltage of the receiving device is equal to or greater than a first threshold. The circuit device includes a humidity detection section configured to detect an ambient humidity of the transmitting and receiving devices and a threshold adjustment section configured to calculate, based on the detected ambient humidity, a sound pressure of the ultrasonic wave that is received by the receiving device after propagating over a round-trip distance between the ultrasonic sensor and the object. The threshold adjustment section reduces the first threshold, when the output voltage corresponding to the calculated sound pressure is less than a second threshold that is greater the first threshold.

摘要： An exhaust manifold has inner and outer tubes made of stainless steel and welded to flanges provided at inlet ports of the exhaust manifold, from which exhaust gas discharged from an engine enters the exhaust manifold. The inner tube has flat portions, and shield plates disposed within the inner tube protect the flat portions from being directly vibrated by pressure waves of the exhaust gas. Accordingly, the vibration of the flat portions is lowered, so that high frequency noise from the exhaust manifold is reduced.

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.
