摘要： PROBLEM TO BE SOLVED: To enhance safety of a device mounting an internal apparatus, by detecting overheat state of the internal apparatus quickly.SOLUTION: Through holes 3 are formed in a heat-sensitive plate 1 for planar thermostat so as to penetrate from one side to the other side thereof. Since radiation r from an internal apparatus reaches the inner lid 4 of a thermostat 6 and a guide pin 5 through the through holes 3, the inner lid 4 and the guide pin 5 are heated by the radiation r together with the heat-sensitive plate 1 for thermostat, and the heat escapes to the side of the inner lid 4 and guide pin 5 of lower temperature than the heat-sensitive plate 1 for thermostat, thus preventing temperature rise of the heat-sensitive plate 1 from delaying as much as possible. Consequently, overheat state of the internal apparatus is detected quickly, and safety of a device mounting the internal apparatus can be enhanced.

摘要： PROBLEM TO BE SOLVED: To efficiently and accurately fill a through-hole with filling ink without deposits on the four edge faces, two longitudinal edges faces and two lateral edge faces, of a printed board, by filling holes in the edge faces of the printed board which deteriorates the printed board markedly in productivity. SOLUTION: A pressing roll 5 is so provided as not to make its peripheral part come into contact with ink 10 which is properly controlled in volume and shape by an ink scraper 7 to fill a through-hole. That is, the pressing roll 5 is arranged at a proper station so as to prevent ink 10 from adhering to it, whereby ink 10 is prevented from adhering to the edge faces of the printed board 1. In a hole filling process, the printed board 1 is kept moving continuously at a constant speed. To prevent ink 10 from adhering to the four edge faces of the printed board 1, the board 1 is made to move continuously at a constant speed till the through-hole is treated with a squeegee after the through-hole is filled up with ink 10.

摘要： PROBLEM TO BE SOLVED: To maintain the cutoff condition even when a reset shaft is held inserted for any reason. SOLUTION: The thermostat TH1 is structured so that the internal connection between terminals 10, 11 is broken by a snap motion of a bimetal 15 and it is restored by insertion of a reset shaft 9. Two sets of contacts are provided, consisting of movable contacts 3, 4 moving in response to the snapping motion of the bimetal 15 or the inserting motion of the reset shaft 9 and stationary contacts 1a, 2a in the fixed arrangement in confronting the movable contacts 3, 4. When the bimetal 15 is in a snap motion, the contacts 1a, 3 are opened, and when the reset shaft 9 is inserted, the contacts 2a, 4 are opened, and the condition is maintained as long as the reset shaft 9 is inserted.

摘要： PROBLEM TO BE SOLVED: To provide a make and break contact switch with a contact reducing the possibility that a foreign material is caught therein stably operating for a long period of time by providing a small projection opposite to the plane-form external surface of a first contact in a part of the external surface of the hill-like spherical surface of a second contact. SOLUTION: The displacement of a bimetal dice 2 is transmitted to a contact spring 4 through a guide pin 3 to bring a movable contact 5 provided at its one end into contact with a fixed contact 6 or separate it therefrom. In the above-mentioned thermostat 1, the external surface of the movable contact 5 is formed into a hill-like spherical surface, and a small projection is provided in a part of the hill-like spherical surface. The movable contact 5 is formed of, for instance, a connection part 7 made of copper and a contact part 8 made of silver, and a small projection 8b having a height of not more than 0.1mm is formed in the contact part body 8a of a hill-like spherical surface. Therefor, when a foreign material is caught between both contacts, sure contact is obtained, and the foreign material is removed by arc discharge generated in being used several times and at the same time the small projection itself disappears. After that, the make and break operation of both contacts is stabilized.

摘要： PROBLEM TO BE SOLVED: To prevent the explosion of a battery sustainable from the result of overcharge, a shortcircuit or the like. SOLUTION: The power supply circuit of a safety device 5 is formed out of components ranging over a power generation element 2 to an electrode cover 18 via a lead wire 22, the terminal 21 of a conductor case, a cylindrical frame 11, a PTC board 15, an annular terminal 16 and a contact piece 17. When the state of overcharge or shortcircuit occurs, the PTC board 15 generates heat, thereby restraining an overcurrent flow. Regardless of the current flow restrained, however, the heat generation of the PTC board 15 causes a rise in the temperature of a temperature hole opening disc spring 13 up to the prescribed level. Then, the disc spring 13 is reversed and pushes up the contact piece 17 to interrupt the power supply circuit. When gases are generated, pressure quickly rises. Thus, a pressure hole opening disc spring is reversed to push up the contact piece 17, thereby interrupting the power supply circuit. When the pressure continues to rise, an aluminum foil 8 is broken, and gases are released outside to prevent the explosion of a battery case 3.

摘要： PURPOSE:To prevent an external liquid leaking from a pressure switch for opening and closing a contact through the detection of the pressure of a liquid- operated circuit. CONSTITUTION:A pressure sensitive section 8 and a switch section 10 are housed in a housing 2. In addition, a metallic case 4 is coupled and fixed to the open side of the housing 2 via an O-ring 6. Furthermore, the metallic case 4 has a pair of leads 50 and 51 inserted and led in such state as sealed with a glass material. Also, the inner end sections of the leads 50 and 51 are connected to the terminals 52 and 54 of the switch section 10, and the outer end sections are connected to harnesses 64 and 66. The leads 50 and 51 are formed to have a pipe form, and pins 56 and 58 soldered to the switch terminals 52 and 54 are inserted in the pipe leads 50 and 51. In this case, the outer end sections of the pipe leads 50 and 51 are welded, thereby keeping electrical connection between the pins 56 and 58, and liquid tightness in the lead pipes 50 and 51.
