摘要： An ultrasonic wave generating device includes a substrate, a heat insulation layer on the substrate, a membrane heating portion on the heat insulation layer, and a membrane oscillator on the heating portion. The heating portion is electrically driven with a predetermined period, and produces heat for thermally displacing a surface of the oscillator. The oscillator receives a temperature variation with the predetermined period from the heating portion, and oscillates so as to generate ultrasonic waves.

摘要： An ultrasonic sensor includes a plurality of vibrating parts, a plurality of receiving elements, and a waveguide. Each of the vibrating parts vibrates when a corresponding ultrasonic wave reflected by a detection object is transmitted thereto, and receives the ultrasonic wave. Each of the elements includes corresponding one of the vibrating parts and detects the object using the corresponding ultrasonic wave. The ultrasonic wave is transmitted through the waveguide to each of the elements. The waveguide includes a first opening facing the object, a second opening, and a reflecting surface that reflects the ultrasonic wave in a direction to each of the vibrating parts. The ultrasonic wave enters through the first opening. The second opening is not viewable from the first opening. The second opening holds the elements such that the each of the vibrating parts faces a direction where the each of the vibrating parts receives the ultrasonic wave.

摘要： An ultrasonic sensor for detecting a position and/or a shape of an object located around an automotive vehicle is mounted on a structure of the vehicle such as a bumper. The ultrasonic sensor includes a receiving member for receiving ultrasonic waves reflected on the object to be detected and receiving element having plural vibrating portions. The receiving member is sectioned by intercepting slits into plural receiving regions each corresponding to each vibrating portion. The intercepting slit eliminates or suppresses crosstalk between neighboring receiving regions, and thereby reducing detection noises due to the crosstalk and improving detection sensitivity of the ultrasonic sensor. The shape of the intercepting slit is made to satisfy the formula: 0.35≦L/T≦0.60, where L is a depth of the slit and T is a thickness of the receiving member. In this manner, the crosstalk resulting in detection noises is sufficiently suppressed.

摘要： An ultrasonic sensor includes an ultrasonic detecting element, an acoustic matching member, and an oscillation damping member. The ultrasonic detecting element detects an ultrasonic wave. The acoustic matching member has a receiving surface that is adapted on a side of the certain object to be exposed to a space, in which the detected body exists. The receiving surface receives the ultrasonic wave reflected by the detected body. The acoustic matching member is made of a material having an acoustic impedance larger than that of air and smaller than that of the ultrasonic detecting element. The oscillation damping member is disposed between an attachment portion and the acoustic matching member. The attachment portion is adapted for attaching the ultrasonic sensor to the certain object. The oscillation damping member damps transmission of oscillation from the certain object to the acoustic matching member.

摘要： An ultrasonic sensor composed of a substrate and a piezoelectric vibrator mounted on the substrate is advantageously used as a sensor for detecting a distance to an object located in front of an automotive vehicle. Ultrasonic waves transmitted from the sensor are reflected by the object, and the reflected waves are received by the sensor. Based on the reflected waves, the distance from the vehicle to the object is calculated. To reduce rigidity and thereby to lower a resonant frequency of the substrate to a desirable level, grooves are formed in the substrate. A thickness of the substrate is not reduced to maintain its mechanical strength against an impact force. A resonant frequency which is desirable to realize a sufficiently high directivity and sensitivity is obtained in this manner without enlarging a size of the ultrasonic sensor.
