  • Patent number: 8242773
    Abstract: A holder is disposed in the case. The holder is mounted with an actuator that moves in the predetermined direction and a wiring board having a detector. A positioning mechanism between relevant components for detecting the positions of components is provided such as a wiring board and a holder, the position of magnet in particular. In this way, the magnet and the detector opposing to each other are positioned. As a result, when a vehicle switch is assembled, the variation in position of the magnet and detector is reduced.

  • Patent number: 8154367
    Abstract: Regarding a switch used for various controls of a motor vehicle in particular and a switch device using the switch, it becomes possible to simplify the configuration and to perform reliable detection of trouble. A first detector is disposed on a surface opposing to a magnet fitted to an actuator, and a second detector is disposed thereunder. A controller detects magnetism of the magnet by using the first detector and the second detector. In case one of the detectors is out of order, it can also be detected from ON/OFF signal from the first detector and the second detector.

  • Publication number: 20100307708
    Abstract: Unlike related art in which a variety of recycling aluminum materials are directly inputted into a pre-rolling melting furnace, the present invention provides the step of melting used planographic printing plates roughened by hydrochloric acid-based electrolysis in another melting furnace into a recycled metal ingot having a predetermined shape and weight and the step of using the results obtained by analyzing the recycled metal ingot to determine the mix proportions of the recycled metal ingot, the fresh metal ingot, and the trace metal master alloy to be inputted into the pre-rolling melting furnace. As a result, the amount of CO2 produced at the time of manufacture can be greatly reduced, and an aluminum plate having an aluminum purity of 99.0% or higher, which is required in a hydrochloric acid-based electrolytic roughening, can be manufactured.
