    • A double gong bell has an outer gong and an inner gong separately arranged to accommodate the inner gong within the space defined by the inner surface of the outer gong. In one embodiment at least two hammer driving members, disposed within the space defined by the inner surface of the outer gong and slidably supported within a mounting means are adapted for reciprocal movement upon the action of a hammer driving means. The ends of the hammer driving members closest to the gongs are attached to a first resilient member and a hammer. A pair of second resilient members attached to the hammer driving members and the mounting means are biased to urge the hammers to strike the inner and outer gongs upon the action of the hammer driving means generating a bell sound having composite tone colors.
    • 双锣钟具有外锣和内锣,分别布置成将内锣容纳在由外锣内表面限定的空间内。 在一个实施例中,设置在由外锣的内表面限定并且可滑动地支撑在安装装置内的空间内的至少两个锤驱动构件适于在锤驱动装置的作用下往复运动。 最靠近锣的锤子驱动构件的端部附接到第一弹性构件和锤子。 附接到锤驱动构件和安装装置的一对第二弹性构件被偏压,以在锤驱动装置产生具有复合色调的铃声的作用下促使锤撞击内和外锣。

    • A cylindrically shaped valve rod is housed in a valve hole formed in a cylinder body in a manner so as to be rotatable around a center axis line, and a connecting hole having a first hole opening that is allowed to communicate with a first flow path hole, and a second hole opening that is allowed to communicate with a second flow path hole is formed in the valve rod. A flow adjusting groove that is extending in a circumferential direction around an outer periphery of the valve rod from a position of the first hole opening is formed, and the flow adjusting groove is formed such that a groove width gradually narrows toward a tip end side and the groove depth gradually shallows at the same time, so that the valve opening extent is adjusted along with rotating operation of the valve rod.
    • 圆柱形的阀杆容纳在形成在缸体中的阀孔中,以便能够围绕中心轴线旋转,以及具有第一孔口的连接孔,其允许与第一流路孔 并且在阀杆中形成允许与第二流路孔连通的第二孔开口。 形成有从第一开孔的位置沿圆周方向围绕阀杆的外周延伸的流量调节槽,并且流动调节槽形成为使得槽宽朝向前端侧逐渐变窄, 槽深度同时逐渐变浅,因此阀门开度随着阀杆的旋转运行而调整。

    • An alarm device capable of producing an audible as well as a visual alarm is disclosed. The alarm device comprises a gong, a DC motor of a commutator type and a hammer operatively connected to an output shaft of the motor for striking the gong. The alarm device further comprises a high-voltage generating circuit connected to the motor, a flash tube and an exciter circuit for the tube. When a DC power is supplied to the motor to strike the gong by the hammer, the high-voltage circuit generates a high voltage in accordance with a square-wave current which flows through the motor. The exciter circuit is energized by the high voltage and excites the flash tube to thereby produce flashes of light.
    • 公开了能够产生听觉和视觉警报的报警装置。 报警装置包括锣,换向器型的直流电动机和可操作地连接到电动机的输出轴的敲击锣的锤。 报警装置还包括连接到电动机的高压发生电路,闪光管和用于管的激励器电路。 当直流电被提供给电动机以通过锤撞击锣时,高压电路根据流过电动机的方波电流产生高电压。 励磁电路由高电压激励,激发闪光管,从而产生闪光。
