摘要： PROBLEM TO BE SOLVED: To provide a valve device having simple construction for opening a valve with a low pressure loss when a fluid is supplied to flow and for closing the valve when the fluid is not supplied. SOLUTION: The valve device 1 provided in a water distribution flow path of a fuel cell system comprises a valve stem 2 provided in a valve box 5 having a valve hole 6 across the flowing direction, a valve element 3 provided on the valve stem 2 in an axially rotatable manner for opening and closing the valve hole 6, a magnetic part 10 formed of a magnetic substance and provided on the valve element 3, and a permanent magnet 11 provided outside the valve hole 6. The valve element 3 is always energized to the valve closing direction with the magnetic effect of the magnetic part 10 on the permanent magnet 11. When water flows, the magnetic element 3 is pushed by fluid pressure to open the valve, and when the water does not flow, it closes the valve by a magnetic energizing force to suppress the convection of gas in the flow path. The valve element energized by the magnetic force can be operated by a relatively small force at the initial stage of opening the valve against the energizing force. When water does not flow in the flow path, the valve element 3 can be restored into a valve closing state by the relatively weak magnetic force. Thus, the weak magnetic force is required to be set, resulting in the lower pressure loss. COPYRIGHT: (C)2007,JPO&INPIT
摘要翻译：要解决的问题：提供一种阀装置，其具有简单的结构，用于在流体供应流体时打开具有低压力损失的阀，并且当不供应流体时提供关闭阀。解决方案：设置在燃料电池系统的分配流路中的阀装置1包括设置在具有沿着流动方向的阀孔6的阀箱5中的阀杆2，设置在阀上的阀元件3 阀杆2可轴向旋转，用于打开和关闭阀孔6，由磁性体形成并设置在阀元件3上的磁性部分10以及设置在阀孔6外侧的永久磁铁11.阀元件3是总是通过磁性部件10在永磁体11上的磁力作用向阀关闭方向通电。当水流时，磁性元件3被流体压力推动以打开阀门，并且当水不流动时，它关闭阀通过磁力来抑制气流在流路中的对流。通过磁力激励的阀元件可以在打开阀抵抗通电力的初始阶段通过相对小的力来操作。当水不在流路中流动时，阀芯3可以通过相对较弱的磁力恢复到关闭状态。因此，需要设定弱磁力，导致较低的压力损失。版权所有（C）2007，JPO＆INPIT

摘要： PROBLEM TO BE SOLVED: To form a valve in compact size, and make it possible to open and close it under low pressure without lowering seal performance.
SOLUTION: One end of a cylindrical valve box 2 is set as an inflow port 3, and the other end is set as an outflow port 4. A valve seat 5 is formed on the inflow port 3, and a valve element 6 is movably provided. The valve seat 5 is composed of a circular magnet concentric with a valve hole 5c centered to a cylinder axis. The valve element 6 is formed of magnetic material. The valve element 6 is attracted to the valve seat 5 by magnetic force to close the valve hole 5c in the valve seat 5, and it opens the valve hole 5c by fluid pressure. The magnetic field from the circular magnet is distributed as a concentric circle along its circumference. Attracting force to the valve element 6 is uniformly added around the axial center of the valve hole 5c. The valve element 6 is attracted by a dense magnetic field at an inner circumferential part of the magnet to be guided toward the valve hole 5c constantly along the axial center. The valve is thus smoothly opened and closed. Since a stopper 7 in the valve box 2 regulates the valve element 6 to move in an effective range of the magnetic force, valve restoration force can be adjusted. By providing a porous member 8 impregnated in oil on the valve seat 5, seal performance can be effectively secured.

摘要： PROBLEM TO BE SOLVED: To provide a relief valve for an electrical double layered capacitor which is small in size and has a high performance.
SOLUTION: In an opening of a vessel 7 with an electrolyte inside, a gasket 2 is installed. In the opening of the vessel 7, there is also a disc spring-like disc 3 with a bottom which selectively connects or disconnects the inside and outside of the vessel 7, depending whether it closely contact the gasket 2 or not. Normally, the disc 3 is in close contact with the gasket 2 and seals the vessel 7. When the internal pressure of the vessel 7 becomes the release operation pressure or above, the disc 3 moves inversely in a direction away from the gasket 2, connecting the inside and outside of the vessel 7. Under the sealing recovery pressure or below, the disc 3 returns to the original condition to be adhered to the gasket 2 and seal the vessel.

摘要： PROBLEM TO BE SOLVED: To provide a safety device which can avoid the danger of firing and explosion caused by the misuse (abnormal use) of a battery. SOLUTION: In a safety device 10, lower aluminum foil 4 provided with an air vent 4b on a concentric circle at a center fusing position C is fused to the bottom surface of a metallic case 1, and upper aluminum foil 3 laminated with the lower aluminum foil 4 with an insulating ring 5 sandwiched at their contours is fused at the fusing position C to form a sealed element 20, with a ring-shaped PTC(positive temperature coefficient) element 6 placed on the upper surface of the upper aluminum foil 3 while being sandwiched between the upper surface of the foil 3 and the peripheral edge of a terminal cap 2. If the resistance value of the PTC element 6 increases as the result of the flow of an excess current, a current conducted decreases to prevent damage to a battery. When gas is produced, the gas directly presses the upper aluminum foil 3 through the air vent 4b in the lower aluminum foil 4, exerting a shearing force on the vent hole 4b and causing rupturing of the lower aluminum foil 4. The aluminum foils 3, 4 are separated from each other to shut off a current in a current- conducting path to prevent the temperature of the battery from rising. As the internal pressure further rises, the upper aluminum foil 3 is pressed against the inner peripheral edge of the PTC element 6 and ruptured to allow the gas to leak out.
摘要翻译：要解决的问题：提供一种可以避免电池误用（异常使用）引起的爆炸和爆炸危险的安全装置。解决方案：在安全装置10中，在中心熔接位置C的同心圆上设置有排气孔4b的下铝箔4熔融在金属壳体1的底面上，与铝箔在其熔合位置C处熔合具有夹在其轮廓上的绝缘环5的箔4以形成密封元件20，其中环形PTC（正温度系数）元件6放置在上铝箔3的上表面上，同时被夹在箔3的上表面和端帽2的周缘之间。如果PTC元件6的电阻值随着过电流的流动而增加，则传导的电流减小以防止损坏电池。当产生气体时，气体通过下铝箔4中的通气口4b直接压入上铝箔3，在通气孔4b上施加剪切力并引起下铝箔4的破裂。铝箔3， 4彼此分离以截止导通路径中的电流，以防止电池的温度升高。随着内部压力进一步升高，上部铝箔3被压靠在PTC元件6的内周边缘上并破裂，从而使气体泄漏。

摘要： PROBLEM TO BE SOLVED: To improve insulating performance without making a pressure switch and a thermostat large in size.
SOLUTION: In the pressure switch or the thermostat in which by installing a switch part S having a pair of terminals 11, 12 in a resin base member 1 having the peripheral wall part 14 in the whole periphery, by covering a resin made middle cap 2 on the terminal 11 side of a movable side of the switch part S, by placing a metallic reversing disc 5 on the outside of that middle cap 2, and by reversing the direction of the reversing disc 5 to a switch part S side, the middle cap 2 pushes the terminal 11 of the movable side and the paired terminals 11, 12 are made to contact or separate, at the outer peripheral part of the middle cap 2, an annular protruding part 13 surrounding the switch part S by protruding to the switch part S side is installed at the whole periphery. Since the annular protruding part of the middle cap 2 and the peripheral wall part 14 of the base member 1 make an insulation distance between the switch part S and the reversing disc 5 and a cap 10 longer, its insulation performance can be improved without making the device large in size.

摘要： PROBLEM TO BE SOLVED: To provide a valve element which can exhaust gas generated from the inside of an electrolytic capacitor to the outside.
SOLUTION: Seals 8, 9 are arranged so as to close both ends of the aperture of a cylindrical housing 10 which are opened at an upper part and a lower part. The seals 8, 9 are made of a porous member 5 wherein a large number of very detailed holes, air gaps, etc. which pass gas and do not pass water are formed. The porous member 5 which is impregnated with oil 7 is arranged on the upper surface of the lower seal 9. A space is arranged between the porous member 5 and the upper seal 8. When the seals are attached in the electrolytic capacitor, humidity outside the capacitor passes the seal 8 and can enter inside the housing 10, but the humidity can not pass the porous member 5 and not advance inside the capacitor due to action of the oil 7 with which the porous member 5 is impregnated. When gas is generated at the inside of the capacitor and internal pressure rises with generation of the gas, the gas passes the lower seal 9, becomes air bubbles, passes the porous member 5 and is exhausted outside the capacitor through the upper seal 8.
