Abstract: PURPOSE:To perform one-to-many switching and mixing of plural light beams at a high speed with low power consumption and high reliability by varying the intensity of a magnetic field applied at right angles to a film surface and the intensity and the direction of a magnetic field applied in the surface. CONSTITUTION:Optical input fibers 4a and 4b are connected across a polarizer 7 to one side of a garnet film 9 as a magnetic material forming a nonionic injection disk 1 (having an ion injected area shown by 3), and an output fiber 5 is connected to the opposite side across an analyzer 8.

Patent JP-H0722700-A (JP)
Title: Wavelength selecting switch
Inventor: SAKATA HAJIME
IPC: H01S5/50
Filed: 1993-07-06
Abstract: PURPOSE:To selectively separate an arbitrary wavelength from a wavelength- multiplexed optical signal by forming a guided mode/emitting mode converter by at least partly duplicating two guided modes on a region in which the two modes are interacted to each other. CONSTITUTION:A guided mode/emitting mode converter 14 is formed on a phase matching grating 13. Accordingly, a light transferred from a mode 1 to a mode 2 is immediately emitted, and not returned to the mode 1 even if an interacted region is longer than a completely coupling length. Therefore, the interacted region, i.e., the grating 13 is formed longer than the coupling length, thereby effectively emitting a selected light to be space-separated.

Title: Finite rotation motor
Inventor: OTA KAZUO
IPC: H02P3/00
Filed: 1989-06-30
Abstract: PURPOSE:To control a minute angle at high speed and with a high accuracy by detecting a direct-acting operation through a position sensor after converting a motor rotation angle into the direct-acting operation through pinion and rack, by obtaining a deviation between a temperature-compensated sensor signal and position command signal and a speed command signal deviation, and by feedback-controlling these deviations so that they are reduced to zero. CONSTITUTION:In a moving coil type motor 1 using a high flux density magnet, the rotation angle of the motor is converted into DC voltage by a DC tachometer generator 3 and into the direct-acting operation of a magnetic plate 7 via pinion and rack 4, 5 and further converted into a signal by a non-contact sensor 8. Then, a position sensor signal Vpf passed through a temperature compensator 10 and a position command signal Vpo from a commander part 9 are compared by a first comparator 11 so that a position deviation signal  Vp is outputted and inputted to PID controller to output a speed command signal Vs. In a second comparator 13, the speed command signal Vs and a feedback signal Vsf from the tachometer generator are compared with each other and a speed deviation signal  Vs is outputted and inputted to a power amplifier 14 to output a motor control signal Vout.

Title: Method and apparatus for measuring tire breaker rro
Inventor: KOJIMA YOSHIHIDE
IPC: G01B17/00
Filed: 1991-07-08
Abstract: PURPOSE:To measure breaker RRO continuously and efficiently by sending ultrasonic wave toward a rotating tire under water and receiving the ultrasonic wave reflected by a breaker of the tire. CONSTITUTION:A tire 13 is installed in a rotary shaft 12 and the tire 13 is rotated on the rotary shaft 12. Ultrasonic wave is sent toward the center of the radial direction of the tire 13 from an ultrasonic wave head 14 under water and the ultrasonic wave reflected from the breaker 16 is received by the supersonic wave head 14. Since the measurement carried out part of the tire 13 is under water, ultrasonic wave becomes easy to go into the tread rubber and breaker RRO can be measured and the measurement is carried out continuously and efficiently by rotating the tire 13.

Title: Headlamp device for vehicle
Inventor: KATO YOSHIKI
IPC: F21S8/10
Filed: 1998-06-15
Abstract: PROBLEM TO BE SOLVED: To reduce the number of part items by eliminating the need for optical device for removing a light-less part in a middle part other than a projector lens. SOLUTION: A first light-guide material 4 and a second light-guide material, each having a substantially elliptic cross-section shape, are used. The rays of light incoming into the minor axis direction side of an incoming end 40 of the first light-guide material 4 and the second light-guide material, are converged on the middle part side of an outgoing end 41 of the first light-guide material 4 and the second light-guide material, while the rays of light incoming into the major axis direction side of the incoming end 40 of the first light-guide material 4 and the second light-guide material, are diffused to the both end part sides of the outgoing end 41 of the first light-guide material 4 and the second light-guide material. The rays of light outgoing from the outgoing end 41 of the first light-guide material 4 and the second light-guide material, each having a substantially elliptic cross-section shape, form a light distribution pattern PW having a horizontally large irradiation area and, at the same time, a high- illuminance hot zone HZ substantially in a middle part of the light distribution pattern PW, and therefore no optical devices are needed for removing a light-less part in the middle part, thus reducing the number of part items.

Filed: 1989-06-29
Abstract: PURPOSE:To increase a resonance driving wave number and to improve detecting accuracy by forming a curved conduit by resin or the like having excellent workability and anticorrosion and fixing a metallic rod with high rigidity to increase Coriolis force.

Abstract: PURPOSE:To make the title cooker more convenient, by a method wherein a cooking-starting means for rice, a timer means, and a control means for inputting a signal from a temperature-detecting means are provided, and the rice is cooked by a heating means. CONSTITUTION:A control means 7 controls a heating means 2 and begins to start rice-cooking when a signal from a cooking-starting means 4 for rice is inputted therein, and decides that the temperature of a food being cooked in a vessel 1 is beyond a definite temperature when a signal from a temperature- detecting means 6 is inputted therein. After that, the control means 7 controls a timer means 5, and begins to start a timer, and controls by a heating means 2 so that the rice is cooked until the time of the timer elapses by the time preset by a timer-presetting means 3 after a signal from the timer means 5 is inputted therein. In addition, a microcomputer 12 inputs a signal outputted from an A/D converter 6c for the temperature-detecting means 6, and decides whether the temperature of the food cooked in the vessel 1 is higher than the temperature of 90 deg.C or not.

Title: Bending angle measuring method
Inventor: MARUYAMA RYOSUKE
IPC: G01B21/22
Filed: 1988-07-05
Abstract: PURPOSE:To measure the bending angle efficiently by providing two distance sensors shifted heightwise and widthwise directions each other in a bracket. CONSTITUTION:A pair of distance sensors 3a, 3b which are shifted each other at least in a heightwise direction and in a widthwise direction (shifting distance l1, l2) are provided at a measuring surface 2b which confronts to one piece 1b of an article 1 and which has a predetermined angle theta1 from a reference surface 2a in contact with the other piece 1a of the article 1. Distances A, B between the piece 1b of the article 1 and the measuring surface 2b are measured by sensors 3a, 3b. The bending angle theta of the article is obtained by a predetermined formula based on the distances A, B and the prefetermined angle theta1. Since the sensors 3a, 3b are shifted each other in the widthwise direction, even when the angle theta of the small article 2 can be measured with the distance l1 reduced, the actual distance l2 between the sensors 3a, 3b can be elongated and accordingly bed influences due to a mutual interference of the sensors can be removed. Therefore, the distance of even a small article can be measured correctly.
