    • An electroacoustic transducer adapted to be mounted on a printed circuit board in which a coil spring is accommodated and supported in a cylindrical recess of a frame while it is fixed to neither a terminal plate nor the frame. Particularly, a protruding pin of the coil spring is passed through a though hole of the terminal plate to allow a leading portion of the protruding pin to be hooked thereon. When the electroacoustic transducer is mounted on the printed circuit board, any horizontal displacement between the compressed spring and the printed circuit board would not cause stress concentration on the coil spring since the coil spring is onlly horizontally shifted in the cylindrical recess until a coil portion of the coil spring hits against the wall of the cylindrical recess.
    • 一种电声换能器,其适于安装在印刷电路板上,其中螺旋弹簧被容纳并支撑在框架的圆柱形凹部中,同时固定到端子板或框架。 特别地,螺旋弹簧的突出销穿过端子板的通孔,以允许突出销的引导部分钩在其上。 当电声换能器安装在印刷电路板上时,压缩弹簧和印刷电路板之间的任何水平位移不会引起螺旋弹簧上的应力集中,因为螺旋弹簧在圆柱形凹槽中水平移位,直到线圈部分 螺旋弹簧撞击圆柱形凹槽的壁。

    • A hydraulic pressure control device in a vehicle anti-skid braking system includes a wheel brake actuating cylinder for braking a vehicle wheel, a fluid pressure supply passage connected between a master cylinder and the wheel brake actuating cylinder and having a restriction, and a first directional control valve disposed in the fluid pressure supply passage and having at least pressure-increasing and pressure-decreasing modes, the first directional control valve being normally in the pressure-increasing mode to connect the master cylinder to the fluid pressure supply passage. A second directional control valve is connected between the master cylinder and the wheel brake actuating cylinder, the second directional control valve being normally open to provide a bypass passage across the first directional control valve to connect the master cylinder passage to the wheel brake actuating cylinder. A control unit is responsive to a decelerating condition of the vehicle wheel for actuating the first directional control valve into the pressure-decreasing mode and for actuating the second directional control valve to shut off the bypass passage.

    • To provide an electret capacitor microphone in which change of sensitivity characteristic caused by thermal deformation of an electret layer can be prevented even in the case where a reflow process is carried out. An electret capacitor microphone includes: an electret capacitor portion including a diaphragm, and a back electrode plate disposed opposite to the diaphragm through a spacer; an electrically insulating bush for electrically insulating/supporting an outer circumferential edge portion of the back electrode plate; a metal cover in which the electret capacitor portion and the electrically insulating bush are stored; and a gate spring having a pressing function for elastically pressing the back electrode plate toward the diaphragm to form a predetermined gap between the electrically insulating bush and an inner surface of a rear wall of the metal cover. Consequently, collapse of a spacer-abutting portion of an electret layer is prevented from being caused by thermal expansion.
    • 为了提供即使在进行回流处理的情况下也能够防止由驻极体层的热变形引起的灵敏度特性的变化的驻极体电容式麦克风。 驻极体电容器麦克风包括:包括隔膜的驻极体电容器部分和通过间隔件与隔膜相对设置的背电极板; 电绝缘衬套,用于电绝缘/支撑背电极板的外周边缘部分; 其中存储驻极体电容器部分和电绝缘衬套的金属覆盖物; 以及具有按压功能的闸门弹簧,用于将背面电极板朝向隔膜弹性按压,以在电绝缘衬套和金属盖的后壁的内表面之间形成预定的间隙。 因此,防止了驻极体层的间隔件邻接部分由热膨胀引起的塌陷。
