Patent JP-S58174706-A (JP)
Title: Pump flow control device
Inventor: FUJITA YASUO
IPC: F15B11/17
Filed: 1982-04-07
Abstract: PURPOSE:To solve insufficiency of a flow in case the plural number of selector valves are operated simultaneously by providing such a piston as the pressure in each pilot circuit of which works individually in the same direction. CONSTITUTION:A piston 8 is composed of stepped pistons, for example, and pressure of each individual pilot circuit 4 is introduced into each of said step part for operation of said pressure in the same direction so that pushing pressure corresponding to the total pressure of each pilot circuit 4 is generated. Further, the structure of a pressure control valve 9 is such that the valve 9 generates, on the secondary side circuit 7a, the pressure corresponding to a load which is produced due to a flexure of a spring caused when a spool is pushed by the piston 8 through a spring in case the piston 8 is pressed. Accordingly, even if the plural number of selector valves are operated simultaneously, a discharge quantity control device 6 can be operated with the pressure corresponding to the total pressure of each pilot circuit 4.

Abstract: PURPOSE: To measure the quantity of movement in the width direction of a metallic beltlike body accurately by a method wherein a rotatory polyhedral mirror is mounted at the location of the focus of a parabolic mirror, the luminous energy of the metallic beltlike body is scanned, and converted into electric signals by means of an infrared sensor and a location of an edge is detected.  
     CONSTITUTION: A parabolic mirror 2 is installed to the upper or lower section of a metallic beltlike body 1 while a rotatory polyhedral mirror 3 is set up at a location of the focus thereof. The luminous energy of the metallic beltlike body 1 is inputted to an infrared sensor 4 through the parabolic mirror 2 and the rotatory polyhedral mirror 3, the value is converted into electric signals and the location of an edge is measured continuously by means of a signal processor 6 during the movement of the beltlike body 1 by the reference signals of a reference location detector 5 separately mounted. Thus, the quantity of the movement of the metallic beltlike body 1 can be measured in high accuracy because light energy signals which the rotatory polyhedral mirror 3 scans do not change.

Filed: 1987-03-13
Abstract: PURPOSE:To improve input/output characteristics and to obtain a sufficient power gain in a high frequency range by applying a DC bias between a base and an emitter in a power amplifier using a hetero junction bipolar transistor. CONSTITUTION:A DC bias smaller than the ON voltage of a hetero junction bipolar transistor (HBT) 11 is applied between the base and the emitter of the input side of the HBT11 by the HBT11 having narrower band gap of a base region than that of an emitter region as an element having an amplifying operation.

Title: Coordinate input device with back light
Inventor: KUMADA OSAMU
IPC: G06F3/03
Filed: 1989-03-09
Abstract: PURPOSE:To remove the unevenness of brightness in a back light part without converting a lighting polarity by arranging respective cathodes at the time of lighting up a fluorescent lamp with DC so as to be opposed to the anode of the other fluorescent lamp or arranged adjacent to the anode. CONSTITUTION:The fluorescent lamp 5 is arranged so that the cathode side of the other fluorescent lamp 5 is arranged on the other side end face position of a light guide 1 opposed to the another side of the fluorescent lamp 5. Since respective brightness uneven states generated by respective lamps 5 are mutually inverted, the unevenness of a light emitting face can be removed by reversely superposing these brightness uneven states. Even when an extinction phenomenon is generated in the cathode due to long DC lighting, the light emitting face of the light guide 1 is prevented from generating the unevenness of brightness.

Title: Electrolytic cell of water using solid polymer electrolyte membrane
Inventor: INASUMI CHIKASHI
IPC: C25B9/19
Filed: 1998-03-10
Abstract: PROBLEM TO BE SOLVED: To prevent damages to an ion exchange membrane by press-joining a reinforcing ion exchange membrane layer to the area of the ion exchange membrane to be in contact with a sealing member. SOLUTION: The electrode-joined membrane 3 consists of an ion exchange membrane 4 with a thick peripheral part and anode-side and cathode-side catalyst electrode layers 5, 6 attached to both faces of the membrane 4. The ion exchange membrane 4 is obtd. by press-joining a frame-like reinforcing ion exchange membrane 39 to a flat ion exchange membrane body 4a. By this constitution, since the part of the ion exchange membrane 4 to be in contact with an O-ring gasket 24 is reinforced, the outside of the O-ring gasket 24 of the ion exchange membrane 4 is dry while the inside is wet, so that even when large stress generates in the peripheral part of the ion exchange membrane 4, no damage is caused in the ion exchange membrane 4. Moreover, since the thickness of the part in contact with anode and cathode feeders 7, 8 where an electric current is applied does not change, the electric resistance is not increased.

Abstract: PURPOSE:To enlarge an operating margin by supplying the power source of a sense amplifier, a decoder and a comparing circuit from a voltage limit circuit in a non-volatile semiconductor memory device. CONSTITUTION:In the non-volatile semiconductor memory device, a voltage limit circuit 2, whose output limit voltage is a Vt, is provided. This voltage is supplied to the gates of a Y-decoder 3, an X-decoder 4, a sense amplifier 5, a sense amplifier 6 for reference, a comparing circuit 7, a reference transistor 11 and a Y-transistor 10 for reference. When Vcc<=Vt is obtained for an input voltage Vcc<1>, the device is operated samely as a conventional example. In case of the Vcc>=Vt, since Vout=Vt is always obtained, a reference level is always set to the medium of output levels L and H of the sense amplifier 5. Thus, the apparent writing depth of a memory transistor 9 is caused to rise in comparison with the conventional device and the operating margin is enlarged.

Abstract: PURPOSE:To improve the performance of an engine at the time of its idling operation, by preventing leakage of fuel by feeding compressed air from a supercharger to holes having a shaft of a throttle valve fitted therein, providing a valve at an intermediate portion of a supercharging-pressure transmitting passage, and opening the valve only when the supercharging pressure is higher than a prescrbed value. CONSTITUTION:A supercharging-pressure transmitting passage 7 formed in an upper suction barrel 2 is connected via a valve 8 to bearings fitted at diameter- reduced portions 5, 6 of a throttle valve shaft 4 disposed at a lower suction barrel 11. At the time of idling operation of an engine, its supercharger is not oprated, so that a valve member 9 of the valve 8 closes the upper suction barrel 2 side of the passage 7 by the force of a spring 10. On the other hand, when the supercharger is in operation, the valve member 9 is released by the supercharging pressure supplied from the side of the upper suction barrel 2, so that the supercharging pressure is acted in holes into which the throttle valve shaft is inserted and the pressure in said holes is balanced with the pressure acted in the lower suction barrel 11. Therefore, it is enabled to prevent leakage of fuel to the outside from the side of the suction barrel.
