Patent JP-H0477607-A (JP)
Title: Stage-position detecting mechanism
Inventor: TONO HIDEHIRO
IPC: G01B11/00
Filed: 1990-07-20
Abstract: PURPOSE:To make it possible to obtain the detecting accuracy which is twice that of a conventional device by using a reflector by which an incident light path and a reflecting light path are deviated in parallel, and providing a fixed mirror for measuring light which reversely reflects the measuring light to advance in the reverse direction. CONSTITUTION:Measuring light LM is obtained by splitting laser light L from a laser light source 9 through a light splitting optical system 15. The measuring light LM is sequentially reflected from two reflecting planes 21a and 21b of a stage reflector 21. Then, the light is reflected with a fixed mirror 22 for the measuring light and made to advance in the reverse direction. The measuring light LM which is reflected from the reflector 21 and the fixed mirror 22 is overlapped on reference light LR which is reflected from a fixed mirror 11 for the reference light in an interference optical system 18, and one luminous flux LI is formed. The luminous flux is cast into an interferometer detector 10 under the interfered state. The detector 10 measures a displacement (d) of the reflector 21 from an original point 0 based on the change in light path of the measuring light LM in the interfered luminous flux LI and detects the position of the stage. In this way, the detecting accuracy is twice that of a conventional apparatus. Therefore, the moving stage of a stepper can be adjusted with sufficient accuracy.

Title: Rear wheel steering angle controller for four-wheel steered vehicle
Inventor: SHIMOYAMA OSAMU
IPC: B62D7/14
Filed: 1989-07-24
Abstract: PURPOSE:To secure the safe traveling by forming a rear wheel steering angle restricting mechanism for restricting the max. steering angle for steering rear wheels to a prescribed steering angle beforehand as a mechanical mechanism using only a hydraulic system, at least in the case when the car speed is high. CONSTITUTION:When the car speed increases, and the revolution speed of a propeller shaft 12 increases, the oil quantity discharged from a hydraulic pump 11 increases, and the speed passing through the throttle part of a venturi pipe 18 increases, and the pressure in a high pressure passage 19 increases, and the pressure in a low pressure passage 20 lowers, and the differential pressure increases in proportion to the increase of the car speed. Further, when the car speed increases, and the differential pressure between in the oil passages 19 and 20 increases, the piston 5b of a steering angle restricting power cylinder 5 is pushed down to the lowest position, and a steering angle restricting pin 4 reaches the bottom of a steering angle restricting groove 3. Therefore, the movement of the rod of a rear wheel steering power cylinder 2 is restricted, and the steering angle for steering a rear wheel 1 is restricted within a small steering angle. Even if a trouble is generated in a rear wheel steering angle control system such as the cylinder 2, valve 10, etc., the rear wheel 1 is not steered in the large steering angle.

Title: Method and device for amplifying light
Inventor: HENMI NAOYA
IPC: H01S5/06
Filed: 1989-07-25
Abstract: PURPOSE:To recover a gain with a relaxation constant equal to or under a picosecond by inputting signal light which is within the amplification-enabled wavelength band of a light amplifying medium and has different wavelength from the oscillated wavelength of an optical oscillator in the light amplifying medium and obtaining the amplified light as output. CONSTITUTION:A semiconductor laser amplifier 1 having the gain in a constant wavelength band is used as the semiconductor amplifying medium, and an optical resonator constituted of two mirrors, which are (a) terminal 9 obtained by mirror-coating the end of an optical fiber and a wavelength selection mirror which reflects and returns constant light out of the light outputted from the end 17 of the fiber to the end 17 of the fiber by a lens 14 and a diffraction grating 15, is used as an outside optical resonator. Since the optical resonator has the semiconductor laser amplifier 1 functioning as a gain medium in itself, oscillation occurs by increasing an inrush current from a direct current source 30 and enhancing the amplification factor of the semiconductor laser amplifier. Thus, the relaxation time that an original state is restored from an amplification saturated state is accelerated to be equal to or under a picosecond.

Abstract: PROBLEM TO BE SOLVED: To provide an interferometer provided with a pass match optical system for measuring the surface shape of a transparent thin plate and can form the high-contrast interference fringe image of a surface to be inspected with a simple constitution by positioning two polarizing plates and two optical phase plates at prescribed positions on the optical path of the interferometer and only making two luminous fluxes (linearly polarized light) which are required for obtaining the interference fringe image of the surface incident on an observation system. SOLUTION: The light from a light source 1 is transformed into P-polarized light by positioning a first polarizing plate 21 which transmits P-polarized light between the light source 1 and a half mirror 4 and, at the same time, the light which detours a pass match optical system is transformed into S-polarized light by positioning a λ/2 optical phase plate 22 into the optical path of the pass match optical system and synthesized with a luminous flux which advances straight as P-polarized light at the half mirror 4. In addition, the light reflected by a surface 11a to be inspected is transformed into P-polarized light from S- polarized light, or vice versa, by positioning a λ/4 optical phase plate 23 between a reference plate 11 and the plate 12 to be inspected.  Then the transmission of the P-polarized light which becomes background light is blocked by positioning a second polarizing plate 24 which transmits S-polarized light in the preceding stage of an image pickup camera 14.

IPC: G03G15/16
Filed: 1998-07-08
Abstract: PROBLEM TO BE SOLVED: To prevent faulty transfer from occurring even when transfer paper whose the width is sufficiently more narrow than the length of a transfer roller passes by using a roller whose the electric resistance is under a specified value as a transfer roller and forming an air gap within the range of a specified value between a photoreceptor drum and the transfer roller. SOLUTION: In a printer where this image output equipment is applied, a constant current is supplied to the roller shaft of a transfer roller 4. When transfer paper is fed between the roller 4 and a photoreceptor drum 20 in the state that the constant current is supplied to the roller shaft of the roller 4, a toner image on the drum 20 is electrostatically transferred to the transfer paper. Then, the roller whose the electric resistance is <1×109 Ω is used as the roller 4, and an air gap between the drum 20 and the roller 4 is set to a value within the range of >=0.1 mm and <=0.3 mm. Thus, the faulty transfer is prevented from occurring when the transfer paper whose the width is sufficiently more narrow than the length of the roller 4 passes through.

Filed: 1986-08-19
Abstract: PURPOSE:To decentralize a change in current in time wise and to reduce a power source noise by applying a deviation in the activating timing of the sense amplifiers of memory cell groups of two systems selected by the same row level. CONSTITUTION:In the memory cell arrays 11, 12, the plural memory cell groups selected by same row level are divided into memory banks of two systems of A, B. While word lines WL1, WL2 are selected, a constant delay is applied between the system of A, B. At the same time, at the time of selecting sense amplifier activating control lines lines S1, S2, the constant delay is applied between the systems of A, B. Then, data read to input/output lines 41, 42 is converted into serial data through input/output sense amplifiers 51, 52 transfer gates 61, 62, output data latch circuits 71, 72, and shift registers 81, 82 and taken our from an output buffer circuit 9. In such a way, since the deviation is applied to the activation for the sense amplifier, the change in the current can be decentralized in time wise, accordingly, the noise in the power source can be reduced.
