    • An ultrasonic detection device is constructed in such a way as to include a discriminating processing unit (a time width detecting part 13 and a pulse width discrimination part 14) for approximating the shape of each signal which is a reflection signal which is reflected from an object as a result of transmitting a ultrasonic pulse toward the object, or a noise as an isosceles triangle and computing a pulse time width equal to the length of the base of the approximating isosceles triangle, and for discriminating between the reflection signal and the noise signal by determining whether the computed pulse time width exceeds a predetermined pulse width discrimination threshold. Therefore, the ultrasonic detection device can determine the pulse time width with stability, and carry out the discriminating process with a high degree of reliability.

    • An air-coupled ultrasonic sensor capable of changing setting of an output sound pressure or an ultrasonic wave propagation distance depending on a use application, an installation site, or the like, with a simple structure. An air-coupled ultrasonic sensor includes: a closed-end cylindrical case including an opening portion at one end in its axial direction and a bottom surface at another end; a piezoelectric oscillator firmly fixed onto an inner bottom surface of the closed-end cylindrical case; an open-end cylindrical case including opening portions at both ends in its axial direction; and a thin film firmly fixed on one of the opening portions at one end of the open-end cylindrical case. The open-end cylindrical case is fitted to the closed-end cylindrical case, and includes a structure capable of moving along a side wall of the closed-end cylindrical case.

    • An ultrasonic sensor module attaching device and attaching method include an ultrasonic sensor module 1 having a flange 7 of which the diameter is larger than the hole diameter of a through hole 5 prepared through a bumper 4 of a vehicle; and a fixing ring plate 3 having an engaging section 3b with the flange of the ultrasonic sensor module temporarily fixed on the back of the bumper 4 and a large-diameter fixing section 3c which extends circumferentially of the engaging section and is fixed to the back of the bumper 4; thus, the necessity for positioning the fixing ring plate 3 to the hole 5 of the bumper 4 is eliminated, which can attach easily the ultrasonic sensor module 1 to the back of the bumper.
    • 超声波传感器模块安装装置和安装方法包括:超声波传感器模块1,其具有直径大于通过车辆缓冲器4制备的通孔5的孔径的凸缘7; 以及固定环3,其具有与超声波传感器模块的凸缘临时固定在保险杠4的背面上的接合部3b;以及大直径固定部3c,其在接合部的周向延伸并固定在 保险杠4; 因此,消除了将固定环板3定位到保险杠4的孔5的必要性,这可以容易地将超声波传感器模块1附接到保险杠的后部。
