Title: Manufacture of semiconductor laser element
Inventor: HAYAKAWA TOSHIROU
IPC: H01S5/028
Filed: 1979-09-13
Abstract: PURPOSE:To obtain the stable laser light irradiating surface of the semiconductor laser element by adsorbing protective gas for preventing oxidation to cleavage plane of the laser element and covering the protective film on the plane thereof. CONSTITUTION:When the laser element is cleavaged, it is executed in protective atmosphere of N2, H2, Ar or the like. These atmospheric gases are adsorbed to the activated laser cleavaged plane just after the cleavage, and abrupt natural oxidation is suppressed immediately after cleavage. Thereafter, protective film is coated on the cleavage plane, so that stable laser light irradiating surface may be obtained. The atmospheric gas at that time employs N2, H2 Ar or the like having large adsorption speed to Ga1-xAlxAs to be controlled so that O2, H2O for oxidation may not contain in the atmosphere in the step of cleavage the laser element as low as possible.

Title: Aluminum composite member
Inventor: KAJI TOSHIHIKO
IPC: C25D11/04
Filed: 1999-04-26
Abstract: PROBLEM TO BE SOLVED: To enhance the adhesion of a coating film and the mirror finishing properties in the surface by forming an Al-contg. coating film having specified thickness on the surface of an Al alloy-contg. base material having specified crystal grain size. SOLUTION: The base material contains an Al alloy having 0.05 to 10 μm crystal grain size. The coating film has 1 to 30 μm film thickness and contains Al. The purity of Al in the coating film is preferably controlled to >=99.99 wt.%. In this way, at the time of subjecting the coating film to anodic oxidation treatment to form an anodically oxidized film, the anodically oxidized film can be made approximately colorless and transparent. Thus, the transmissivity of visible light in the anodically oxidized film can be increased, and the mirror finishing properties in the Al composite member can be enhanced. The roughness in the surface of the base material is suitably controlled to <3.0 μm by the maximum height (Rmax), by which the adhesion between the base material and the coating film can moreover increased.

Title: Sodium liquid-level meter
Inventor: TAKAHASHI HITOSHI
IPC: G01F23/26
Filed: 1985-06-03
Abstract: PURPOSE:To reduce the space necessary for the feeding-out and feeding-in of a liquid-level meter at the time of the maintenance of said liquid-level meter, by dividing the bobbin, coil and protective pipe constituting a liquid level measuring part into plural parts and connecting said parts by flexible joints each having a shape securing the path communicating inert gas sealed in the passage of the coil and the protective pipe. CONSTITUTION:A bobbin 1, a coil 2 and a protective pipe 3 are divided into plural parts which are, in turn, connected by joints 15. Because each joint 15 takes out the induced voltage signal generated by the coil of each part and the mutual action of liquid levels, it is necessary to connect the coils of the divided parts to each other. Then, it is necessary to secure the passage therefor and to bend the same at the times of feeding-in and feeding-out. Because of this, each joint 15 is formed into a structure having flexibility.

Title: Liquid pressure brake device for vehicle
Inventor: TODA HIROSHI
IPC: B60T8/48
Filed: 1994-05-31
Abstract: PURPOSE:To control independently the brake liquid pressure of two vehicle wheel brakes by means of inexpensive actuators. CONSTITUTION:When the brake liquid pressure of vehicle wheel brakes 13, 14 is reduced suddenly, the brake liquid is made to flow out to a low pressure reserver 19 by operating a solenoid changeover valve 20. The brake liquid of the low pressure reserver 19 is returned to a master cylinder 12 side by means of a motor-driven pump 25. Although the brake liquid flows into the vehicle brakes 13, 14 from the master cylinder 12 side via orifices 26, 27, its flow is small, and sudden depressurization is not hindered. When a solenoid cutting-off valve 21 and/or a solenoid cutting-off valve 22 are/is operated, the slow pressure increase of the vehicle wheel brake 13 and/or the vehicle wheel brake 14 is carried out by the inflow of the brake liquid from the orifices 26, 27. When the operation of the solenoid changeover valve 20 is released and at the same time the operation of the cutting-off valve 21 and/or the cutting-off valve 22 are is released, the sudden pressure increase of the brake liquid pressure of the vehicle wheel brake 13 and/or the vehicle wheel brake 14 is carried out.

Title: Dc generating circuit for actuator control
Inventor: SAITOU AKIHIKO
IPC: G11B5/588
Filed: 1983-06-30
Abstract: PURPOSE:To generate always an optimum DC for control even in case of variable speed reproducing by changing the period of a generated saw tooth wave signal in accordance with a tape speed. CONSTITUTION:When a rotation pulse signal FG corresponding to the running speed of a magnetic tape is generated, a saw tooth wave generating circuit 1 outputs a saw tooth wave signal AC' where a two-field time is one period. Meanwhile, the signal FG is shifted successively by an n/2-stage shift register 5 and is supplied to an n-notation counter 6. Consequently, a saw tooth wave generating circuit 4 outputs a saw tooth wave signal BC' whose phase is shifted from that of the signal AC' by 180 deg.. A head switching signal HS is differentiated, and a positive-polarity differential signal corresponding to the rise of this signal HS is outputted from a diode 10, and the signal AC' is sampled and held by turning-on of a transistor TR15. Consequently, an inverting amplifier 21 generates a controlling DC signal ADC for a head A. By an inverted signal of the signal HS which is supplied through an inverter 11, a controlling DC signal BDC for a head B is generated synchronously with the fall of the signal HS. The similar operation is performed also in case of variable speed reproducing.

Abstract: PROBLEM TO BE SOLVED: To automatically reproduce various information according to a procedure without requiring a control file such as a command file by reading files out of a storage medium in the order of reproduction numbers and reproducing them on the basis of reproduction information. SOLUTION: In the file names of respective files of image data, sound data, character data, etc., reproduction information representing reproduction procedures of reproduction order, switching time, etc., is registered, and the respective files are stored on a storage medium 10 such as an IC memory card in order. When this storage medium 10 is loaded in a medium I/O 8, a readout control part 12 reads the file names out of the storage medium 10, stores the reproduction information in a memory 17a of a reproduction control part 17, and also stores the reproduction number in the reproduction information in a memory 12a. Then the files stored on the storage medium 10 are read out in the order of the reproduction numbers and reproduced on the basis of the reproduction information.  Therefore, automatic reproduction can be performed according to the reproduction information of the reproduction order, switching time, etc., registered previously in the file names.
