Title: Safety device for throttle valve opening and closing control mechanism
Inventor: YOSHIDA MASATO
IPC: F02D9/02
Filed: 1987-10-28
Abstract: PURPOSE:To enable emergency operation to be performed, when a throttle valve is in trouble, by providing the throttle valve and a closing valve in an intake pipe and closing the closing valve while controlling a bypass valve in a bypass passage when the throttle valve causes the trouble. CONSTITUTION:An intake pipe main passage 1 arranges in series a throttle valve 2 controlled by a servomotor 5 and a closing valve 7 controlled by a rotary solenoid 8. In a bypass passage 3 detouring around these throttle valve 2 and closing valve 7, an idle speed control(ISC) valve 4 is arranged. In the normal time, a control unit controls the servomotor 5 and the throttle valve 2 so as to be in an optimum opening while the closing valve 7 to be fully opened, and the ISC valve 4 controls an idle speed. When the throttle valve 2 is disabled to be controlled, the rotary solenoid 8 drives the closing valve 7 so as to be fully closed, and closing the main passage 1, emergency operation is performed by controlling the ISC valve 4.

Title: Magnetic head
Inventor: SANO KAZUTATSU
IPC: G11B5/17
Filed: 1984-12-21
Abstract: PURPOSE:To obtain a magnetic head that does not cause fluctuation of output even at the time of off-track and does not cause decrease in S/N ratio by applying short-circuit ring to an erasing head core. CONSTITUTION:Besides winding for erase head, short-circuit ring 65 is applied to the erasing head core. It is enough to install such a short-circuit ring 65 to induce a magnetic field in the direction opposite to AC magnetic field induced in the erasing head at the time of off-track. By applying such a short-circuit ring 65, an AC magnetic field induced in the erasing head at the time of off- track can be canceled.

IPC: C23G3/00
Filed: 1985-12-02
Abstract: PURPOSE:To surely clean the narrow and highly rugged parts of a work by setting the work which is subjected to an impregnation treatment and from which an excess impregnating liquid is drained into a cleaning tank contg. a cleaning liquid and rotating the work so that the work is put into and out of the cleaning liquid. CONSTITUTION:The work stuck with the impregnating liquid after the impregnation treatment is rotated in the cleaning tank by which the work is put into and out of the cleaning liquid. The cleaning liquid is forcibly put into and out of the recesses such as holes and pits formed on the work surface to dilute the impregnating liquid in the recesses and thereafter the impregnating liquid is discharged and removed. The impregnating liquid is automatically removed without the aid of a manual operation, by which the efficient sure cleaning of the work is executed. Since the impregnation stage is sequentially executed like impregnating, liquid draining, cleaning, water draining, and drying, the impregnation treatment can be fully automated to meet line tact and the productivity is improved. The work is rotated in directions varying 90 deg. by executing the cleaning stage in two stages, by which the through cleaning in the different directions of the work is made possible. The sure cleaning is thus executed.

Title: Recording data processor
Inventor: OISHI KAZUHIRO
IPC: G07G1/12
Filed: 1990-10-09
Abstract: PURPOSE:To prevent a prepaid card from being issued illegally by erasing cryptographic data stored in a cryptographic data storage means when it is discriminated that every kind of instruction is not a normal instruction by a discrimination means. CONSTITUTION:A reader/writer means 2 performs the encipherment/ decipherment of data in a recording medium based on the cryptographic data stored in the cryptographic data storage means 1, and performs the read/write of the recording medium such as a magnetic card, etc., and an execution control means 3 performs every kind of processing according to every kind of instruction. An erasure means 5 erases the cryptographic data stored in the cryptographic data storage means 1 when it is discriminated that every kind of instruction is not the normal instruction by the discrimination means 4. Therefore, since the cryptographic data is erased when a different instruction is issued even when data is tried to write illegally on the prepaid card, no normal data can be written on the prepaid card. Thereby, it is possible to prevent the prepaid card from being issued illegally.
