Title: Key switch
Inventor: HASEGAWA TAKESHI
IPC: H01H3/12
Filed: 1988-03-07
Abstract: PURPOSE:To make it possible to operate at low noise by employing a bushing section made with a resilient member at a joining section between a means for restricting a key button to move parallel when the key button is operated and the key button. CONSTITUTION:To prevent noise from being produced between a parallelism maintaining bar 5 and ribs 3a, 3b of a key button 2, bushes made of a resilient material are inserted between slit holes 3c, 3d and the fore-ends 5a, 5b of the parallelism maintaining bars 5. The ribs 3a, 3b and the parallelism maintaining bars are joined almost without play due to the resilience of the bush 4a or 4b at either position of the upper and lower dead centers of the ribs 3a, 3b and the fore-ends 5a, 5b of the parallelism maintaining bar, especially even at the intermediate point of a large play. Even if there is a small play, noise is prevented by the resilience of the bushes 4a, 4b.

IPC: H01H73/26
Filed: 1992-01-27
Abstract: PURPOSE: To make free tripping action possible and constitute with a small number of moving members by providing a bimetal thermosensitive element, a trip flag, a movable contact, an oscillating member (actuator), and the like. CONSTITUTION: A trip flag 30 (trip plate) is movably supported in a housing 10, in such a way that a part of the flag 30 leans on a movable contact 18, when a contact is closed and that a part of the flag 30 moves between the contact 18 and a fixed contact 14, when a switch is opened. In the case of a bimetal thermosensitive element 16 being thermally expanded by an excessive current state, the element 16 moves from a normally closed contact position. As a result, the contact 18 is put in mechanical opening action with respect to the contact 14, which is possible also by the movement of the oscillating member 12 into a specified position.  Accordingly, once an element 16 is moved to the member 12 into an off position, the member 12 is prevented from being manually reset to an on position until the temperature returns to normal, thus attaining overload protection of an internal circuit.

Title: Molding die
Inventor: GOTO KAORU
IPC: B29C45/33
Filed: 1993-03-12
Abstract: PURPOSE:To surely prevent the positional deviation of a molded article during ejection from occurring. CONSTITUTION:A molded article 6 has grooves 11 and 12, which are respectively undercut parts, inside three side plate parts. The grooves 11 and 12 are molded respectively by the slide cores 58 and 96 of a movable mold. A mold opening, the three slide cores 58 and 96 are simultaneously ascended, resulting in ejecting the molded article 6 from the movable mold 22. The two slide cores 58, which mold the left and right grooves 12 and have larger releasing resistance start to move horizontally and simultaneously with ascending, resulting in starting to leave from the grooves 12. The one slide core 96, which molds the deep groove 11 and has smaller releasing resistance firstly ascends perpendicularly and then starts to move horizontally, resulting in leaving from the groove 11. Thus, during the leaving of the former slide cores 58 from the grooves 12, the latter slide core 96 suppresses the molded article 6, resulting in preventing the position of the molded article from deviating.
