Title: Semiconductor laser device
Inventor: ADACHI AKIHIRO
IPC: H01S5/00
Filed: 1989-01-09
Abstract: PURPOSE:To obtain a high reflection coupling efficiency eta with a semiconductor laser device and a narrow emission spectrum width with a structure of a small size by using a silicon crystal having a reflecting surface formed to a spherical surface, with its center at the laser beam emitting point and, at the same time, an incident surface also formed to a spherical surface, with its center at the laser beam emitting point. CONSTITUTION:A rear emitted light beam 2 emitted from the rear emitting end face 3 of a semiconductor laser chip 1 is made incident on the plane of incidence 10 of a silicon crystal 9. Since the plane of incidence 10 is a spherical surface having its center at the emitting point of the rear emitted light 2, the light beam advances straight without refraction and is made incident on the reflecting surface 11 of the crystal 9 after passing through the crystal 9 straight. Since the reflecting surface 11 is formed to a spherical surface having its center at the emitting point of the light beam 2, the reflected light beam is necessarily reflected in the direction in which the light beam enters. Therefore, the light beam 2 emitted from the rear emitting end face 3 of the semiconductor laser chip 1 is reflected by the reflecting surface 11 and necessarily re-coupled with the light emitting position on the end face 3 from which the original light beam is emitted and a high re-coupling efficiency eta is obtained.

Title: Tape tension detection device
Inventor: IMAGAWA SEIJI
IPC: G11B15/43
Filed: 1998-01-09
Abstract: PROBLEM TO BE SOLVED: To highly accurately detect tape tension without performing correction by providing a magnetic body with a shape thin and long in a direction vertical to a moving direction and detecting the position of the magnetic body based on the output result of a magnetic/electric conversion means. SOLUTION: When the tension of a traveling tap 1 changes, a movable pin 2 agitated in the direction of an arrow 2 and two magnets attached to an arm are agitated in synchronism with the movable pin 2. A Hall element 9 outputs signals corresponding to the strength of a magnetic field in the direction vertical to the upper surface and an amplifier 10 sends the amplified signals to a tape tension detector 12. Then, the tape tension detector 12 compares the signals from the amplifier 10 with the contents of a memory 11 and calculates the tension value of the tape.  In such a manner, by arranging the magnets above and below the Hall element, turning a magnetic flux in a Z axis direction and prolonging the shape of both magnets in the direction vertical to the agitation direction of the movable pin, the detection error of the tension accompanying the component attaching errors and distortion in Y and Z axis directions is reduced.

Title: Method and circuit for outputting fault alarm of peripheral controller
Inventor: SHIRASAKA ICHIROU
IPC: G06F11/34
Filed: 1991-01-16
Abstract: PURPOSE:To perform preventive maintenance by temporarily storing the content of an error after the content is analyzed and edited and using the stored content for comparison and collation with the content of another error which occurs thereafter and, when a count value is smaller than a fixed value, predicting the occurrence of a fault. CONSTITUTION:When an error occurs, an error analyzing section 5 generates a status byte by analyzing and editing the content of the error, but does not make storing operations and inputs the new status byte to an error comparing section 7, since a flag 10 provided in an error storing section 6 indicates a fully occupied state of the section 6. Upon receiving the status byte from the analyzing section 5, the comparing section 7 receives a corresponding status byte from the storing section 6 and compares both bytes with each other. When both bytes coincide with each other, a fault information output section 9 reads the count value of a counter section 8 and, when the count value is smaller than a prefixed value, outputs a fault alarm to a central processing unit 1.

Title: Liquid receiver
Inventor: HONDA SHIN
IPC: F25B39/04
Filed: 1992-01-10
Abstract: PURPOSE:To obtain a liquid receiver capable of controlling an excess cooling degree of liquid refrigerant in conformity with cooking load. CONSTITUTION:A pipeline 12 on the inlet side of a condenser 2 and a pipeline 14 on the outlet side of the condenser 2 are arranged to run through a case 16 which contains gas refrigerant and liquid refrigerant. The pipeline 12 is installed in such a fashion that it may exchange heat with the liquid refrigerant collected in the case 16 whereas the pipeline 14 is installed in such a fashion that it may exchange heat with the gas refrigerant filled in the case 16. There is communicated a communication pipeline 25 which allows both the liquid refrigerant flowing in the pipeline 14 and the liquid refrigerant collected in the case 16 to enter or leave. When cooking load (refrigerant flow rate) is increased, its increased load generates a liquid drop accompanied by vaporization of the liquid refrigerant in the case 16 and increases a substantial refrigerant quantity which contributes toward a refrigeration cycle, thereby increasing the degree of excess cooling of the Liquid refrigerant at the outlet of the condenser 2. This construction makes it possible to maintain the refrigeration cooling efficiency at an optimum level.

Title: Liquid crystal display element
Inventor: KUBO KIICHIRO
IPC: G02F1/1343
Filed: 1987-01-12
Abstract: PURPOSE:To permit control of the spacing between upper and lower substrates to a desired value by arranging plural pieces of metal wirings intersecting with the sealing part on the specific side between the upper and lower substrates of a liquid crystal cell by distributing the adjacent spacings between the same nearly evenly over the entire length of the sealing part on said side. CONSTITUTION:Plural pieces of the metal wirings 2 intersecting with the sealing part on the specific side of the liquid crystal cell are arranged by distributing the adjacent spacings between the same nearly evenly over the entire length of the sealing part 1 on side regardless of the disposition of transparent electrodes 5 for display arranged irregularly on the display surface. The display element, in the case of a chip on LCD (liquid crystal), is constituted of the transparent electrodes 5 for display consisting of ITO transparent conductive films and an LSI chip for driving the liquid crystal display element. The length of the sealing part and the number of the metal wirings in the drawing-out part are the same. The drawing- out parts of the metal wirings are disposed so as to correspond to the positions where the transparent electrodes for display are disposed. The pressure to be exerted between the upper and lower substrates is thereby uniformly acted on the respective parts over the entire surface of the substrates. The spacing sizes between the upper and lower substrates are thus maintained uniformly and correctly maintained at desired values at any point. The generation rate of the uneven color defect of the liquid crystal display element is thereby greatly lowered.
