Title: Rotary compressor
Inventor: NISHIMURA KOICHI
IPC: F04C18/32
Filed: 1996-03-12
Abstract: PROBLEM TO BE SOLVED: To prevent wear-out of a contact part between a vane tip end part and a roller and improve reliability by providing a roller fitted to the outer circumference of an eccentric part and a gear-form part geared with a contact part with a vane contacting the tip end thereof with the outer circumference face of the roller and partitioning a compression chamber into a high-pressure and low-pressure chambers. SOLUTION: A refrigerant gas flowing from a cooling system is sucked into a low-pressure chamber 5b of a compression chamber 5 from an suction path 18, is compressed by eccentric swinging of a roller 30, and delivered from a delivery part 19. Part of the outer circumference of the roller 30 fitted to a crankshaft eccentricity part 4 forms a tooth form part while the tip end part of a vane 32 accommodated reciprocating-slidably in a vane groove 6 forms a tooth-form part. The ear end part of the vane 32 is pushed by means of a spring in an assembling state, and the tooth-form part at tip end thereof and the tooth-form part of the roller 30 are contacted in geared state. Thereby, sliding movement by which a contact point changes is eliminated, and rolling movement by which each contact point changes anywhere is obtained.

Title: Photocatalyst having catalytic activity in visible light region
Inventor: SHINOHARA KIYOAKI
IPC: B01J23/847
Filed: 1996-03-12
Abstract: PROBLEM TO BE SOLVED: To obtain a photocatalyst showing catalytic activity against light within a visible light region and having a laminar structure by adding a transition metal element in the constitutional elements of a photocatalyst respresented by a specific structural formula. SOLUTION: A photocatalyst having catalytic activity within a visible light region composed of composite oxide decomposing water by light to generate hydrogen and/or oxygen is represented by general formula, AB2 C3-x Mx O10-x (wherein A is hydrogen or an alkali metal element, B is a divalent element containing an alkaline earth element, C is a pentavalent element, M is a trivalent element and (x) is an arbitrary number of 0-3). Concretely, M is Fe or Ni and A is H or Na and B is Ca or Cr and C is V or Nb. Since a transition metal element is added to constitutional elements, catalytic activity is shown even against light within a visible light region and, since the interlaminar parts of a laminar structure can be utilized as a place of hydrocracking reaction, a larger quantity of hydrogen can be generated.

Title: Output buffer circuit
Inventor: ABE KOICHI
IPC: H03K19/0175
Filed: 1995-03-15
Abstract: PURPOSE: To reduce power noise by suppressing the peak of a power supply current attended with a logic state change in the output. CONSTITUTION: When a logic state of an input signal SA is subject to change, at first a 2nd output drive circuit comprising a P-channel MOS transistor(TR) TP2 and an N-channel MOS TR TN2 drives a capacitive load CL while using a power capacitor C as an auxiliary power supply. After a delay time by buffer gates B1, B2, a 1st output drive circuit comprising a P-channel MOS TR TP1 and an N-channel MOB TR TN1 drives the capacitive load CL. Since the capacitive load CL is driven at first by using the auxiliary power supply in the case of logic state change, the peak of the power current is suppressed when the logic state is subject to change and power noise is reduced.

IPC: H03H17/00
Filed: 1996-02-19
Abstract: PROBLEM TO BE SOLVED: To output a fixed signal before fluctuation when the fluctuation quantity of an input signal is smaller than a set value and to output a signal suppressing fluctuation when that fluctuation quantity is larger than the set value. SOLUTION: Concerning a digital filter composed of coefficient equipment 2 and 5, adder 3 and delayer 4, a hysteresis circuit 52a is provided for outputting a signal Q when any one of set values Sa and Sb is selected by a switching signal and the difference between an output signal P from the adder 3 and an input signal Q to the adder 3 is smaller than the set value Sa (or Sb) and for outputting the signal P when that difference is larger than the set value Sa and when the fluctuation is small, the fixed signal Q before the fluctuation is outputted but when the fluctuation is large, the signal P suppressing the input signal is outputted.  When this digital filter is utilized for a gradation adaptive and inversion correction type error diffusion processor, even when the gradation is inverted or is not inverted, an image having no flicker can be provided by suppressing the loop vibration of 'gradation characteristic acquisition' → 'error diffusion' →'gradation characteristic acquisition' →... and especially, flicker can be suppressed without lowering the accuracy of threshold value at the time of non-inversion.

Abstract: PURPOSE:To provide an automatic speed change gear which can engage rapidly and assuredly by engaging a solenoid clutch in fixed cycle for a short time to cause an engaging gear to generate a vibration of rotating direction, so that the gear is free from a contact state at a plane portion thereof. CONSTITUTION:When a back R position of a selector switch is selected, a slide gear 13 is axially slided to be engaged with a back gear 23 by action of a hydraulic actuator 23. Simultaneously, an output is generated in AND circuit 36 to operate an oscillation circuit 37 so that a control transistor 38 is turned on in a fixed cycle for a short time to pulse-engage a clutch 1. As a result, power of an engine is intermittently transmitted through first-speed gears 9, 10 to the back gear 23, so that the back gear generates vibration in the rotating direction. Therefore, even if the engaging portion of the slide gear 13 contacts at a plane portion thereof, there is slippage in the contact postion to complete the engagement of the slide bear 13.

Title: Movable position controller
Inventor: SARUGAKU SHINICHI
IPC: G05B19/18
Filed: 1989-03-10
Abstract: PURPOSE:To increase the contact detecting speed and to shorten the time needed for detection of the contact by applying the force acting on the direction opposite to the traveling direction of a movable member to this member at the time of detecting, therefore, reducing the coasting distance of the movable member produced for a period when a distance run by inertia is detected and the movable member is stopped. CONSTITUTION:An actuator 40 which actuates a movable member 9 when a contact is detected is controlled during a sensing action so that the acceleration produced in the direction opposite that so far applied to the member 9 is applied to the member 9 just for a prescribed time. Therefore, the force eliminating the inertia is applied to the member 9. As a result, the satisfactory damping force is applied to the member 9 without using any special and independent damping device, etc. Thus the distance run by inertia of the member 9 can be easily reduced down to a prescribed level despite an increased sensing speed. Then the time needed for the sensing action can be satisfactorily shortened.
