摘要： PROBLEM TO BE SOLVED: To ensure a stable flow rate even with a small differential pressure and to exhibit flow rate stability regardless of a mounting direction.SOLUTION: An annular magnet 2 is provided in a valve body, and a seal 4 made of ethylene-propylene rubber is put on the magnet 2. The seal 4 is used as a valve seat 5, and a valve element 3 made of ferritic stainless steel is provided in an openable/closable manner at the valve seat 5. The weight of the valve element 3 is made less than attracting force of the magnet 2 at the maximum opening of the valve. Dispersion in cracking pressure to the valve mounting direction is thereby reduced to ensure the flow rate stability of a fluid. The surface side, abutting on a valve hole, of the valve element 3 is formed with an adhesion preventing layer 8 made of polytetrafluoroethylene, thereby preventing adhesion between the valve element 3 and the valve seat 5 when a valve closed state continues.

摘要： PROBLEM TO BE SOLVED: To provide a safety apparatus for a battery with which explosion of a battery case caused by the rise of the internal pressure can be prevented. SOLUTION: An electricity flowing route of a safety apparatus 5 comprises a lead wire 18, a terminal 17 of a conductive case 6, a PTC plate 12a, a circular terminal 12b, a contact piece 15, and an electrode cover 16 in this order. When gas is generated from an electricity generating element 2 and the internal pressure of a battery case 3 rises, an aluminum foil 8 swells due to the pressure of the inside of the battery case 3 and a spacer 10 is lifted up. When the spacer 10 is lifted up, the spacer 10 protrudes the center part of a coned disk spring 11 and turns over the coned disk spring 11. When the coned disk spring 11 is turned over, the coned disk spring 11 protrudes the contact piece 15 and parts the contact piece 15 from the circular terminal 12b, so that the electricity flowing route of the safety apparatus 5 is shut. Consequently, electric current is cut and gas evolution from the electricity generating element 2 can be suppressed.

摘要： PROBLEM TO BE SOLVED: To inform of an increase in the internal pressure within an electrolytic capacitor to the outside. SOLUTION: When the internal pressure of an electrolytic capacitor increases, a dome-like inner pressure sensing valve 24 is reversed so as to project in the opposite direction from such a state that it projects to the bottom side, and a pressing member 23 is moved thereby. The movement of the pressing member 23 pushes up the outer circumferential part of a spring member 25 in contact with two lead terminals 22 and 22, and while a projection 211 is used as a fulcrum, the spring member 25 is released from the lead terminals 22 and 22. Therefore, there becomes nonconductive between the lead terminals 22 and 22, and such a state is detected from the outside so that the increase in the internal pressure of the electrolytic capacitor can be recognized.

摘要： PROBLEM TO BE SOLVED: To enable external communication of an increased internal pressure inside an electrolytic capacitor. SOLUTION: When the internal pressure of the electrolytic capacitor increases, a domed internal pressure sensitive valve 24 is inverted like depicting an arc from its downward state to the upward state to push an arm part 221 of a switch member, whereby a contact 222 of the arm 221 is released from a metallic plate 25 electrically connected to an accommodation case 20. As a result, the case 20 and a cap member 21 become nonconductive, but, when the nonconductive state is externally detected, an increased internal pressure of the electrolytic capacitor can be known.

摘要： PURPOSE: To provide a safety device of secondary battery in which whether an operation for keeping safety is performed without breaking or not can be confirmed. CONSTITUTION: A safety device 1 is mounted on a battery case. When a gas is generated in the battery case to raise the pressure in the battery case, an aluminium foil 5 and a moving piece 8 are pushed up by this pressure, and this pressure is transmitted to a disc spring 9 through the moving piece 8. when the disc spring 9 is reversed by this pressure, and both ends of the disc spring 9 are separated from first and second terminals 7, 12, a current-carrying passage is cut to interrupt the flow of current. Thus, the generation of the gas is suppressed, and the rise of pressure is stopped. When the pressure in the battery case is further continuously raised, the aluminium foil 5 is broken to release the gas in the battery case to the outside. Thus, the explosion of the battery case can be avoided.

摘要： PURPOSE: To cut off a charge/discharge circuit without breakage, surely conduct cut-off job, and conduct the cut-off function inspection of the whole product, in the state of overcharge and short circuit. CONSTITUTION: A pressure switch S is fixed to a partition wall 4 between a case 1 and a cover 3. The pressure switch S has such a function that when a coned disc spring 11 is turned reversely, a contact piece 15 is separated from terminals 12a, 12b through a moving contact 14 to cut off a circuit. When the internal pressure in a power generation element zone 2 is increased by overcharge, for example, the coned disc spring 11 is turned reversely to cut off the circuit, and the power generation element zone 2 stops the function to prevent further pressure increase. Since the caned disc spring 11 is instantaneously turned reversely, the cut-off is surely conducted and the circuit is not broken. Since the reversely turning function can be inspected previously, this inspection can be applied to the whole product.
