摘要： PROBLEM TO BE SOLVED: To provide an ultrasonic sensor which secures excellent directivity, even when the ultrasonic sensor is put in a housing and is attached to the rear face of a bumper or a resin part of a vehicle. SOLUTION: In a part of the bottom face portion 3 of the housing 2 interposed between an ultrasonic vibrator 1 and the vehicle bumper 11, an ultrasonic wave transmission portion 4 is made of material different from that of the housing 2. Accordingly, the acoustic impedance of this transmission portion 4 is approached more to the mean value of the acoustic impedances of the piezoelectric vibrator 1 and the vehicle bumper 11, than the acoustic impedance of the housing 2. As a result, transmission of an ultrasonic wave in the bottom face 3 of the housing 2 is performed mainly through the transmission portion 4, when transmission and reception of the ultrasonic wave by the piezoelectric vibrator 1 is performed. Consequently, since a vibration region in the vehicle bumper 11 is restricted, the directivity is prevented from being excessively narrow or irregular. COPYRIGHT: (C)2007,JPO&INPIT
摘要翻译：要解决的问题：即使超声波传感器被放置在壳体中并且安装到车辆的保险杠或树脂部分的后表面上，也提供了确保优良方向性的超声波传感器。解决方案：在超声波振动器1和车辆保险杠11之间的壳体2的底面部分3的一部分中，超声波传输部分4由与壳体2不同的材料制成。因此，该传输部分4的声阻抗比压缩振动器1和车辆缓冲器11的声阻抗的平均值更接近壳体2的声阻抗。结果，超声波在当执行由压电振动器1发送和接收超声波时，壳体2的底面3主要通过透射部分4进行。因此，由于车辆保险杠11中的振动区域受到限制，所以防止方向性变得过窄或不规则。版权所有（C）2007，JPO＆INPIT

摘要： PROBLEM TO BE SOLVED: To secure electric continuity with the electrodes of a piezo-electric vibrator when a resin-made case body is adopted as the case body for an ultrasonic sensor.
SOLUTION: The ultrasonic sensor 90 includes an inner case body 21 which is formed of a resin having a blind cylindrical shape. A conductive film 6 is joined with the bottom surface 21a. One of both the side surfaces of the piezo-electric vibrator 1, where the electrodes are formed, is made to adhere onto the conductive film 6. Accordingly, the electrode contacts the conductive film 6, so as to obtain the electric continuity. When a lead wire 5 is connected to the conductive film 6 and the electrode which is formed on the other surface of the piezo-electric vibrator 1, the electric continuity is secured with the electrodes of the piezo-electric vibrator.

A CPU 25 computes a motion (such as rotational center position and a rotational angle of the vehicle) by a handle angle signal, a vehicle speed signal, a yaw rate signal and an ultrasonic sensor signal, reads the bird's-eye view image obtained at the previous operation timing, rotates, transfers it, overlays the latest bird's-eye view image obtained in this operation timing to create a synthetic bird's eye view image and stores the synthetic bird's eye view image in a history image storage memory 27 and an image memory 29 for display. A monitor 31 displays the synthetic bird's-eye view image including the past history read from a display for display. In a D range, similar processing is executed by using the front camera 11 for photography. COPYRIGHT: (C)2007,JPO&INPIT

摘要： PROBLEM TO BE SOLVED: To provide an obstacle detector capable of positively detecting an obstacle positioned around a vehicle.
SOLUTION: The thicknesses of a bumper 1 and a bottom portion 7 of a housing 6 are established so as not to be greater than a half of a wavelength λ of an ultrasonic wave which a piezoelectric vibrator 2 transmits. This can restrain the reflection of the ultrasonic wave at the bumper 1 and bottom 7 of the housing 6 to increase the transmission efficiency of the ultrasonic wave, thus positively detecting the obstacle positioned around the vehicle.
