Filed: 1998-08-20
Abstract: PROBLEM TO BE SOLVED: To prevent a pressure relief during a high speed rotation while reducing a friction torque during a low speed rotation in a gear pump. SOLUTION: Both ends of a casing 10 having a cavity 14 are closed by a cover 11. A side plate 12 clamping a gear 4 from both sides is floatingly accommodated in the cavity 14. A seal groove 20 is provided on a back surface 12b of a gear side surface of the side plate 12 and a seal 13 of an approximately 3 shape separating the inside of the cavity 14 to a low pressure area L and a high pressure area H is accommodated in the seal groove 20. When a portion 23 at the low pressure area L side of the back surface 12b of the side plate 12 is closely contacted with an opposed surface 11a of the cover 11 by an influence of a disturbance, a gap SH is formed between a concave portion 22 provided on a portion of the high pressure are H side of the back surface 12b and the opposed surface 11a of the cover 11.  A pressure oil is introduced through the gap SH and the side plate 12 is urged back to the gear 4 side by preventing a generation of a fluid anchoring phenomenon.

Title: Directional coupler for polarization plane maintaining optical fiber
Inventor: ISHIKAWA TOSHIHIKO
IPC: G02B6/28
Filed: 1988-09-21
Abstract: PURPOSE:To improve the extinction ratio of the directional coupler for a polarization plane maintaining optical fiber by specifying the ratio of the minor axis diameter of the elliptical jacket of the optical fiber and the clad diameter thereof to a specific value or below. CONSTITUTION:The elliptical jacket type polarization plane maintaining optical fiber having the ratio k=ds/dc of the minor axis diameter ds of the elliptical jacket and the clad diameter dc as small as <=1.2 is used, by which the influence of the stress relief in the polished part of the elliptical jacket which is a stress imparting part and consequently the degree of decreasing the stresses to be exerted to the core are lessened. As a result, the mode coupling between the two orthogonal polarized waves of the light propagating in the optical fiber is shallowed and the directional coupler for the polarization plane maintaining optical fiber which is greatly improved in the extinction ratio is obtd. This coupler is used for an optical measuring instrument such as optical fiber gyro.

Title: Thermal transfer recorder
Inventor: MATSUNO JUNICHI
IPC: B41J31/00
Filed: 1984-11-09
Abstract: PURPOSE:To provide a thermal transfer recorder in which a carrier is neither broken nor deformed and can be easily positioned, by a construction wherein a platen roller with a high coefficient of friction is provided, and a carrier and a recording medium are disposed between a thermal head and the platen roller. CONSTITUTION:The width of the carrier is set to be smaller than that of a recording medium so that the recording medium does not make direct contact with the carrier, whereby a carrier made mainly of a polyester suitable for obtaining high image quality can be fed. Even in the case where feeding for positioning of an extremely thin transfer material with low mechanical strength is impossible because of the high coefficient of friction between a transfer film 1 and a rubber roller 3, protruding of the leading end of the film 1 can be performed under a low coefficient of friction between the film 1 and a recording paper 6, by determining the sizes of the film 1 and the paper 6 so that the film 1 does not make direct contact with the rubber roller 3. Accordingly, defective feeding due to rupture of the extremely thin transfer film 1 or the like does not occur.

Title: Semiconductor device
Inventor: SHIGEKANE TOSHIO
IPC: H03K17/567
Filed: 1984-11-08
Abstract: PURPOSE:To decrease the temperature change of a limit value of a current fed externally by connecting reversely in polarity the 1st and 2nd diodes in parallel between the base of a bipolar transistor (TR) and the cathode of a Zener diode so as to compensate the temperature change in the operating resistance of an FET. CONSTITUTION: One or plural temperature compensation dioded D1 are connected in a polarity in the direction passing through a base current IB. A communication diode D2 commutates a collector current Ic of a main TRQ1 to the Zener diode ZE when composite TRQ1, Q2 are turned off. A large temperature change in the limit value of the collector current Ic is suppressed easily based on the large temperature dependancy of the operating resistance of the FETQ2 without losing the high speed commutation function of the collector current when the composite TRs are turned off.

Title: Image display device
Inventor: INOHARA SHIZUO
IPC: H01J31/12
Filed: 1984-11-08
Abstract: PURPOSE:To discharge high voltage and make visual rectification of image and to make the protection of circuit and the improved quality by utilizing capacity load in signal electrode, and inserting a resistor between the edge of output of signal of PWM circuit and signal electrode. CONSTITUTION:1-kOMEGA resistance in series 50 is inserted between the end of the outputs of respective PWM circuits 37-1-37-n, e.g., the end of the output of pulse amplifier included in PWM circuits 37-1-37-n and respective electricity inducing plates 15-1-15-n of the signal electrode. Thus, even if high voltage is discharged, the high voltage can't be applied to the output part of PWM circuits 37-1-37-n directly by series resistance 50, so that the discharged energy can't be a rapid pulse leading to a rather dull one, achieving the protection of circuit in the output part. Since the signal electrodes forms about 10pF load between other electrodes, the output signal from PWM circuits 37-1-37-n becomes dully by the series resistance and the load capacity, so that almost visual rectification can be realized.

Title: Egr control system for internal combustion engine
Inventor: HARADA YASUO
IPC: F02D21/08
Filed: 1997-09-01
Abstract: PROBLEM TO BE SOLVED: To compute with accuracy a real air-fuel ratio of an internal combustion engine and a target air-fuel ratio thereof as the final target of the opening angle control of its EGR valve whether the engine is at its steady running or transient running. SOLUTION: The real air-fuel ratio of an internal combustion engine 1 is computed in dependence on the detection value of an air-fuel ratio sensor 7 during steady engine running and in dependence on the detection value of an airflow meter 3 during transient engine running. Even during transient running, the detection value of the meter 3 is held substantially equal to the quantity of new charge to be fed into the engine 1, for accurate computations of the real air-fuel ratio. The calculation of a target air-fuel ratio of the engine 1 is based, at steady running, on the real injection quantity of fuel according to the detection values of the meter 3 and sensor 7, not to a requested injection quantity of fuel, and at transient running, on the corrected injection quantity of fuel that takes into consideration changes with the lapse of time of the fuel injection system.  The system thus computes a target air-fuel ratio with accuracy despite of changes with the lapse of time of the injection system.
