Title: Control device for working fluid driving gas injection valve
Inventor: OZU TADAHIRO
IPC: F02M21/02
Filed: 1985-11-26
Abstract: PURPOSE:To easily bleed gas, by providing a route, which drains working fluid, and supplying working fluid of low pressure from a working fluid pump to a drain tank, in the case of a device equipped with the working fluid pump for driving a gas injection valve. CONSTITUTION:High pressure fluid, generated by lifting action of a plunger 33 in a working fluid pump 8, is allowed to flow into a piston chamber 5 of a gas injection valve 1 through a delivery valve 28 and the first passage 7, and the valve 1 injects fuel from a fuel gas flow path 3 by lifting upward a piston 6 and a needle valve 4. Working fluid in the piston chamber 5 returns to a drain tank 10 through the second passage 9 and a relief valve 11. When bleed work of gas in a working fluid route is performed, low pressure fluid, if it is supplied from a hole 36 after opening ball valves 40 for a bypass passage 39 of the delivery valve 38 and placing a selector valve 12 in a conduction position, is drained to the drain tank 10 through a chamber 32, bypass passage 39, ball valves 40, first passage 7, piston chamber 5, second passage 9 and the selector valve 12, thus the bleed work of gas is finished.

Title: Reluctance type motor driven at low voltage
Inventor: BAN ITSUKI
IPC: H02P6/08
Filed: 1988-10-24
Abstract: PURPOSE:To make the fall and rise of exciting currents steep, and to obtain a motor, which has high torque and is turned at high speed, even at low voltage by converting the stored magnetic energy of an exciting coil into the magnetic energy of a subsequently electrified exciting coil. CONSTITUTION:When the electric signal of a curve 54a is input to a terminal 41a to electrify an exciting coil K, and the exciting currents of a dotted line 58a flow. Since transistors 22a, 22b are converted into a non-continuity state at the terminal of the curve 54a, magnetic energy stored in the exciting coil K is discharged as shown in a dotted line 58b. Since there is a diode 49, however, the magnetic energy of the exciting coil K charges a capacitor 47 through diodes 23a, 23b, and increases voltage from a power terminal 2a and quickly dissipates voltage. Consequently, it falls along the dotted line 58b within a range of 45 deg. or less: the generation of antitorque can be prevented. The dotted line 59a of the rise section of the exciting currents of an exciting coil L is made steep by the voltage of the capacitor 47, thus also obviating the generation of de-torque, then turning a motor at high speed.

Abstract: PURPOSE:To exactly set a gap depth and to prevent the degradation in electromagnetic conversion characteristics by wear by forming a magnetic metallic film to one end face of one core material, then machining this material to form a C core and integrally joining the other core thereto. CONSTITUTION:The magnetic metallic film 3 is formed to the end face 11 of the core member 1 to be made into the core 2. The magnetic film 3 is a high saturation magnetic film and is formed to >=3mum thickness. The constituting material thereof is amorphous alloys, such as 'SENDUST' and Co-Zr system. This member is subjected to machining to form the C shaped core which is then joined and integrated to the other core 7 via a gap 6. As a result, the straight line MLJ can be machined to the complete straight lines and the exact measurement and setting of the gap depth are possible. Even if the sliding surface 9 of the head wears, the increase in the exposed area of the magnetic metallic film 3 by the wear does not arise and, therefore, the wear resistance of the sliding surface is not degraded.

Title: Detector of tape termination for tape recorder
Inventor: KENMORI OSAMU
IPC: G11B15/093
Filed: 1984-12-20
Abstract: PURPOSE:To obtain a detector of tape termination which has simple constitution and is free from the defective working due to an aged change, by making use of the displacement caused by oscillations of a cam for detection of the tape termination. CONSTITUTION:Both a revolution detecting arm 12 and a detector 13 continue their oscillations while a tape is driven, i.e., the reel drive disks 1 and 2 are rotated. When a tape take-up action is over, these paired disks 1 and 2 stop their revolutions by the tension applied to the tape. Then the arm 12 stops its oscillations together with the revolutions of the detector 13. Thus a cam 15 of a rotary cam mechanism 19 touches the end face of another side 13b of the detector 13 and the revolution of a cam gear 16 is impossible. However the revolving force is transmitted continuously to the gear 16 from a drive gear 17. Thus the gear 16 is rotated round the axial core of the gear 17. When the gear 16 has a displacement, an oscillating arm 18 is turned counterclockwise. Therefore an automatic inverting mechanism 21 is actuated via a coupling rod 22.
