IPC: G11B15/02
Filed: 1980-07-11
Abstract: PURPOSE:To run a tape automatically, as it was run before the power source is turned off, when the power source is turned on again, by controlling the tape run by storing the tape direction before the power source is turned off when the power source is turned off. CONSTITUTION:During normal-tape-direction reproduction when a power switch 28 is closed, a driving plunger 16 is driven through the 1st driving circuit 15 to set a tape driving mechanism part in a prescribed normal-tape-direction state. When the power source is turned off by opening the power switch 28, a driving plunger 18 and a two-way plunger 23 are turned off, but the moving contact 26a of a changeover switch 26 makes a connection between contacts F and C. Therefore, the tape in the normal tape direction which is the same as that before the power source is turned off. In this constitution, even if the power source is turned on and off repeatedly, the normal tape direction run state before the power source is turned off is set automatically.

Title: Photoswitch
Inventor: YOSHIKAWA TAKEO
IPC: G02B26/08
Filed: 1979-07-26
Abstract: PURPOSE:To obtain a photoswitch of a small size, low electric power and a low price by constituting this by an optical fiber movable structural body, a winding assembly corresponding to this, a positioning guide for both ends of fibers, a fiber aligning structural body and a connecting part. CONSTITUTION:As predetermined electric current is flowed from a fixed direction to a winding 9, the movable part 5 including an optical fiber 7 is attracted to the iron core 1 side, by which the switch is closed. At this time, the fiber 7 moves along a guide pipe 13 and its leading end moves to the leading end of the guide 14. Hence, it goes sufficiently closer to the stationary side fiber and this makes possible the transmission of light. The moving distance of the fiber of this case coincides with the gap between a spring 2 and the iron core 1. Even if the applied current is disconnected after this, the switch is held latched and closed by the residual magnetic flux of the iron core 1. Thereby, low power driving may be accomplished.

Abstract: PROBLEM TO BE SOLVED: To provide an embedded array or a standard cell which incorporates a flash EEPROM that can deal with a request of a client without changing a design method or manufacturing process even if the request is the one that exceeds the time of rewriting which a standard process can guarantee. SOLUTION: Flash EEPROMs 11-1 to 11-3 of the number corresponding to the necessary number of rewriting times are proportionally mounted, all terminals except an input terminal of a chip enable signal are provided to counters 13-1 to 13-3 corresponding to these flash EEPROMs, and the number of erasure times is counted respectively. Then, when a counting value of the counter exceeds the number of rewriting guarantee times, a control circuit 12 selects another flash EEPROM and successively makes it enable state. Since plural flash EEPROMs are switched and accessed, it is possible to guarantee the number of rewriting times corresponding to a demand of a client even when they are manufactured by a standard process.
