    • PURPOSE:To prevent live gas from being discharged at resetting operation of a valve, in which the connection part of a gas cock is provided and the valve is actuated by an electromagnetic operating part, by forcibly attaching a valve main unit to a valve seat through the pressure of gas and opening the valve only through release of the pressure of the gas. CONSTITUTION:If an electric current is conducted to flow in a coil 6 so as to generate magnetic flux in the same direction as a movable permanent magnet 5, the movable permanent magnet 5 is attracted to a fixed iron core 4 against a spring 12. Then a pipe 9 lifts a ball valve 7 to a valve seat position, and the ball valve 7 is forcibly attached to a valve seat 11 by a pressure of gas flowing into a valve main unit 1, then gas is shut off. Then if the coil 6 is electrically conducted so as to generate magnetic flux in the reverse direction to the movable permanent magnet 5, the pipe 9 is depressed by the spring 12. However, the ball valve 7, being pressed by the pressure of the gas, can not be detached from the valve seat 11. Accordingly, a gas cock 2 is shut off before conducting an electric current, and gas in the valve main unit 1 must be previously released by operating a manual button 15.
    • 目的:为了防止活塞气体在阀的复位操作时被排出,其中提供了气体旋塞的连接部分并且阀由电磁操作部驱动,通过将阀主体强制地附接到阀座,通过 气体的压力仅通过释放气体的压力来打开阀门。 构成:如果使电流流过线圈6以产生与可动永磁体5相同方向的磁通,则可动永久磁铁5抵抗弹簧12被吸引到固定铁芯4上。然后, 管道9将球阀7提升到阀座位置,并且通过流入阀主单元1的气体的压力将球阀7强制地附接到阀座11,然后关闭气体。 然后如果线圈6被导电以便产生与可移动永磁体5相反方向的磁通量,则管9被弹簧12压下。然而,球阀7被气体的压力 不能从阀座11拆卸。因此,在进行电流之前关闭气阀2,通过操作手动按钮15,必须预先释放阀主体1内的气体。

    • PURPOSE:To improve the accuracy in sensing earthquakes, by providing a receiving tray of a non-magnetic material which is provided with an iron core for adjusting the spacing from a magnet ball and holding the same in the upper part, accepts the magnet ball and resets the ball in the holding position, and turning a read switch on with the magnetic field of the ball. CONSTITUTION:A groove hole 2 and an iron 3 which can be put into and out of the same are provided in the upper end on the outside in the upper part 1 of a body made of a non-magnetic material. A magnet ball 4 is provided in the hollow and the ball 4 attracts to the core 3 each other and is against gravity. The position of the core 3 is so adjusted that the ball loses the holding force with the core 3 and falls at a set seismic intensity. A receiving tray 5 of a non- magnetic material having an arm shape which accepts the ball 4 and resets the same in the holding position at the top end of the hollow is provided in the hollow. A small iron piece 7 is provided in the lower part 6 of the body so that a reed switch 8 is turned on by the magnetic field of the ball 4 on the tray 5. This seismoscope senses the oscillation of an earthquake with the closure in the circuit of the switch 8. The adjustment of the seismoscope is thus made easy, and the small-sized constitution free from malfunction even if in vertical oscillation is obtained.
    • 目的:为了提高感测地震的准确性,通过提供一种非磁性材料的接收托盘,该托盘设置有铁心,用于调节与磁球的间隔并将其保持在上部,并接受磁铁球, 将球重置在保持位置,并用球的磁场打开读取开关。 构成:在非磁性材料制的主体的上部1的外侧的上端设置有可以放入和移出的槽孔2和铁3。 磁珠4设置在中空部分中,并且球4相互吸引到芯部3并且抵抗重力。 芯3的位置如此调节,使得球与芯3失去保持力并以设定的地震强度落下。 具有臂形状的非磁性材料的接收托盘5设置在中空部中,该托盘5接受球4并将其重置在中空部的顶端处的保持位置。 在本体的下部6中设置小铁片7,使得簧片开关8被托盘5上的球4的磁场接通。该地震仪感测到在该位置处的闭合的地震的振荡 开关8的电路。因此,地震仪的调节变得容易,并且即使在垂直振荡中也能够获得没有故障的小型结构。

    • PURPOSE:To allow valve return operation with a post cock closed, and thereby to attain safety valve function, by leading gas to the downstream of a main valve provided in a valve body by operating a pin opposed to the main valve. CONSTITUTION:When current is supplied to a coil 3 so as to create magnetic flux having a reverse direction to a movable permanent magnet 2, an attractive force between a fixed iron core 1 and the movable permanent magnet 2 is reduced, and accordingly a pipe 7 is urged by a spring 10. However, a ball valve 5 is held in abutment to a valve seat 9 because of gas pressure applied to the ball valve 5. Therefore, prior to supply of current, a post cock 16 is closed, and a manual button 14 outside of the valve body is pushed to open the ball valve 5 with the aid of a pin 12, thereby leading high pressure gas from a primary port 17 to a secondary port 13 to equalize gas pressure in both the ports and to remove gas pressure to the ball valve 5. Upon supply of current, the ball valve 5 is returned. As an even nut and a screw rod are magnetically connected in a meshed manner, when a rotary member 16 corresponding to a drive nut is rotated, a valve shaft 14 which is prevented from rotation is moved forwardly or backwardly in association with the rotation of the rotary member to operate the ball valve 5 supported by the shaft 4.
    • 目的:通过使柱塞阀关闭,从而达到安全阀功能,通过操作与主阀相对的销将气体引导到设置在阀体中的主阀的下游,允许阀返回操作。 构成:当向线圈3提供电流以产生具有与可移动永磁体2相反方向的磁通时,固定铁芯1和可移动永磁体2之间的吸引力减小,因此管7 被弹簧10推压。然而,球阀5由于施加到球阀5上的气体压力而与阀座9保持邻接。因此,在供给电流之前,柱塞16关闭,并且 在阀体外部的手动按钮14被推动以借助于销12打开球阀5,从而将高压气体从主端口17引导到次级端口13,以均衡两个端口中的气体压力并且去除 球阀5的气体压力。在供给电流时,球阀5返回。 由于均匀的螺母和螺杆以啮合的方式磁连接,所以当与驱动螺母相对应的旋转部件16旋转时,阻止旋转的阀轴14随着旋转部件16的旋转而向前或向后移动 旋转构件来操作由轴4支撑的球阀5。

    • A cleaning sheet has a base sheet, a foamed layer of a porous material on the base sheet and a polishing layer formed on the foamed layer. The foamed layer includes non-fibrous abrading particles and air bubbles. Such a cleaning sheet may be produced by preparing a paint having air bubbles dispersed inside by mechanically foaming a foaming material containing a foaming resin material and abrading particles, forming on the base sheet a foamed layer having abrading particles dispersed inside by coating a surface of the base sheet with this paint and drying it, and forming a polishing layer on the foamed layer. A probe having a tip may be cleaned with such a cleaning sheet by causing a surface of its polishing layer to be pressed against the tip of the probe and causing the tip of the probe to penetrate the polishing layer and further to be inserted into the foamed layer having abrading particles dispersed inside.

    • A path of a signal extends from an initial point through first and second cells to an end point. The signal is supplied as a first signal to the first cell and outputted therefrom as a second signal. The signal is supplied as a third signal to the second cell and outputted therefrom as a fourth signal. First delay amounts of the signal in the first cell and a transition time of the second signal are calculated based on a transition time of the first signal and a voltage supplied to the first cell. Second delay amounts of the signal in the second cell and a transition time of the fourth signal are calculated similarly. Here, the transition time of the second signal is set to be a transition time of the third signal. Jitter values in the end point are calculated based on the first and second amounts.
