| 1987 | Invention patented by Hiroshi Matsuda, Haruki Kawada, Kunihiro Sakai, Yuko Morikawa, Ken Eguchi, Takashi Hamamoto, and Masaki Kuribayashi on December 21th, 1987. Abstract: A switching device is provided which comprises a pair of electrodes, and a insulating zone and a conductive or semiconductive zone that are provided between said electrodes. Another switching device is also provided which comprises a pair of electrodes, and a laminated structural body in which an insulating thin film and a conductive or semiconductive thin film are alternately laminated between said electrodes in the direction vertical to the surfaces of said electrodes. This device may be used for a switching process in which an electric circuit is switched from the switched off state to the switched-on state by irradiation of electromagnetic radiation. |
| 1990 | Invention patented by Tomoaki Itabashi on July 9th, 1990. Abstract: A switching device having an operation button member to be depressed includes at least one contact member to be moved by the operation button member when the operation button member is depressed. The contact member is electrically conductive and a conductive member for contacting the contact member when the operation button member is depressed by a predetermined amount is provided. An elastic member is arranged opposite to the at least one contact member with respect to the conductive member, so as to be elastically deformed when the operation button member is depressed, after the contact member has contacted the conductive member. |
| 1992 | Invention patented by Rombaut Willy on June 21th, 1992. Abstract: A switching device for an on-off switching of electrical current operable units includes a first series of first switches which are each time connected with an address generator which is connected via a bus with a branching member, which branching member is further connected with a second series of second switches on which the units are connectable. The branching member further includes a control signal generator which is connected with the address generator and which is provided for, under control of the control signals, fetching the address each time under the form of partial addresses from the address generator. |
