Title: Radiographic image information reader
Inventor: ISHIKAWA HIROMI
IPC: G03B42/02
Filed: 1985-01-18
Abstract: PURPOSE:To attain small size for a light collecting means of luminescent light offering ease of manufacture by laminating a thin film having a high refractive index having a light inlet grating at one end and a photodetector to the other end to a substrate having a low refractive index so as to form a light guide board and using it as the light collecting means of luminescent light. CONSTITUTION:The light collecting board 1 consists of the substrate 2 having a low refractive index and the thin film 3 having a refractive index formed on the surface of the substrate, the light inlet grating 4 is formed to one end of the thin film 3, the photodetector 5 is connected to the other end and a lens form light collecting section 6 is formed at a midpoint. An excited light 8 scanning a storage fluorescent sheet 7 excites a storage fluorescent layer of the sheet 7, from which the luminescent light 9 corresponding to the picture image information stored and recorded is emitted. After the luminescent light 9 is reflected directly or in a concaved mirror 10, the light is made incident to the light inlet grating 4 of the light collecting board 1, propa gated in the thin film 3 and collected by the lens light collecting part 6, made incident to a photodetecting face of the photodetector 5 and converted into an electric signal. The electric signal corresponds to image information stored and recorded on the sheet 7.

Title: Motor driving device for motor-driven power steering
Inventor: AOTANI TOMOAKI
IPC: B62D5/04
Filed: 1987-01-13
Abstract: PURPOSE:To improve the linearity of the output torque for the steering torque by effectively utilizing the electric current continuation effect by a flywheel diode, by setting the frequency of the pulse width modulation signal for high speed switching higher than an audio frequency region. CONSTITUTION:The uppers FET1 and FET3 for maintaining the electric conduction in the right/left steering are turned-ON, so far as the voltage outputted from a torque sensor TS continues when a steering wheel 100 is steered right and left, and the lower FET2 and FET4 for the high speed switching in the right/left steering perform high speed switching for the repetition of ON/OFF operation by a PWM modulation signal. Since the input signal level supplied from the torque sensor TS is proportional to the steering power which a driver supports onto the steering wheel 100, the superior linearily of the output torque of a motor M for the steering power is obtained, and the steering feeling which a driver's hand receives is improved.

Abstract: PURPOSE:To obtain a magentic bubble element with less deterioration in bias magnetic field margin or the like and excellent in the electric characteristic by forming a diameter of a bubble as a specific size or below and a product between the thickness of a hard bubble suppressing layer by ion implantation and the saturated magnitization of magnetic thin film to a limited value. CONSTITUTION:In a magnetic bubble element forming a bubble transfer pattern by a soft magnetic substance, the diameter of bubble is <=1.7mu and the product between the thickness t(mu) of the hard bubble suppressing layer by ion implantation and the saturated magnetization 4piMs(Gauss) of the magnetic thin film is taken as >=10 Gauss.mu and <30 Gauss.mu. The 4piMs of the magnetic garnet layer and the thickness (t) of the ion implantation layer are measured and the relation betwen them and the margin of a bias magnetic field is shown in Figure. In Fig., there are regions (arked X) without margin at smaller (t), and this indicates that errors without reproducibility occur and the hard buble suppression is incomplete. This limit exists at regions with lower 4piMs and larger (t).

IPC: G01R1/073
Filed: 1984-01-18
Abstract: PURPOSE:To position a line of chips and the moving direction of a stage parallel to each other with accuracy and facility by a method wherein the movement of semiconductor devices being successively manufactured is made to look roughly immobile by regularly interrupting the light beam thrown upon a moving wafer or by regulary interrupting the reflection from the wafer. CONSTITUTION:For the satisfaction of an equation theta=0, a light beam, serving the operator watching the pattern on a wafer on a stage moving back and forth by means of a microscope or the like, is regularly interrupted at frequency T that equals Nd/v, where d is the repetition frequency of chips 22, v the traveling speed of the stage, and N a natural number. When a traveling wafer is exposed to a light beam switched off and on at frequency T, the wafer seems to the operator as if occupying the same position every time the light is switched on, provided theta equals 0. When the frequency is so chosen somewhere between several tens to several 100mm. per second as to fall in the range of the afterimage phenomenon, the chips 22 as the operator watches them seem to be immobile. When theta-, the chips 22 seem to move slowly up and down as the stage reciprocates. It is easy to adjust and realize theta=0.

Abstract: PURPOSE:To effectively operate a GTO and to reduce the capacity of an OFF gate condenser by forcibly turning OFF a transistor which turns the gate ON by a synchronizing signal synchronized with a gate OFF current. CONSTITUTION:When an OFF pulse logic signal is generated from a logic unit 21, a transistor 20 is turned ON through the primary winding of a pulse transformer 22, and a reverse bias synchronizing signal is applied between the emitter and the base of a transistor 3 through the second winding 23 in synchronization with that.

Filed: 1999-01-14
Abstract: PROBLEM TO BE SOLVED: To increase the excitation efficiency of a photocatalyst, and at the same time, efficiently bring the photocatalyst into contact with air containing odor components by filling deodorizing grains containing the photocatalyst having a catalyst reaction to deodorize the odor components in air by ultraviolet rays in a container, and providing a means to stir the deodorizing grains in the container. SOLUTION: A large number of deodorizing grains 3 are filled in a container 5, and an ultraviolet light source 2 is disposed at the central section in the container 5 in parallel with the ventilation direction, and a fan 4 is disposed at the lower section of the container 5. Air is fed from the lower direction into this air purifying device 1 by the fan 4, and at the same time, the group of the deodorizing grains 3 in the container 5 is stirred by the air force. Respective deodorizing grains 3 move in the container, and when the grains move to the ultraviolet region from the light source, a photocatalyst contained in the deodorizing grains 3 is excited. Also, since respective deodorizing grains 3 move at random in every direction in the container, the grains 3 collide with air containing odor components, and the odor components are adsorbed by an adsorbing agent contained in the deodorizing grains 3, and the odor components are decomposed by a catalyst reaction by the excitation of the photocatalyst.

Abstract: PURPOSE: To keep the interval between a pickup cartridge and a record disc surface constant by detecting the interval between the tip of the pickup arm and the record disc surface to control driving of the pickup arm vertically.  
     CONSTITUTION: Assuming that angle detection arm 15 and record disc 5 are in proper positions in case of angle θ 1  between them, lights of the same quantity are incident onto CdS elements 18 and 19 and voltage levels at their both ends are equal to each other because angle detection arm 15 which operates as an optical shutter is placed in the middle between CdS elements 18 and 19. In case of warp of the record disc surface, the detected angle is changed from θ 1 Wθ 2 , and element 19 is cut off by arm 15, and therefore, the output of differential amplifier 21 rises in the positive direction to generate torque in rotor 28, and pickup cartridge 13 is lifted. Consequently, the interval between the pickup cartridge and the record disc surface is kept constant.
