Patent JP-H0348023-A (JP)
Title: Connection mechanism
Inventor: MIROSURAFU PETORUTSUEKA
IPC: F16C3/02
Filed: 1990-06-25
Abstract: PURPOSE: To break a pipe axial to cope with the requirement of energy at the time of head-on collision of automobiles when an axially pressurized pressure is greater than a lengthwise adhesive strength between the end of a pipe and a sleeve, and the pipe axial made of fibrous composite material changes its wall thickness along the length by additional windings to glide on the sleeve. CONSTITUTION: A connecting element 8 is closely fitted in a tooth form 2 on the end of a sleeve 1 to be contact-joined to the inside cylindrical surface of an end 7 of a pipe. At the end part 7 of the pipe, the wall thickness of the pipe is thicker by additional windings as it approaches the end to form a thickness 10 capable of having effect on transition of breaking force at the end part to reduce the progress of the breaking force. Further, when the thickness of the end of the pipe is thinner the breaking force progresses. Thus, breaking of the end 7 of the pipe can be controlled in time sequence, or the elapse of stress can be demonstrated to cope with the requirement on absorption of energy of automobiles at the time of head-on collision.

Title: Magnetic encoder
Inventor: ONO HIROYUKI
IPC: G01D5/245
Filed: 1993-07-02
Abstract: PURPOSE:To heighten measuring precision of a speed and a position by arranging a plurality of magnetic detection means at a symmetrical position of a magnetic record medium and reducing the amplitude fluctuation of a detection signal of a magnetic field. CONSTITUTION:An A-phase signal (B-phase signal) transmitted from leads L1-Ln are added with a group of addition circuits in order. The output of a final stage addition circuit 15 is the total of signals of the leads L1-Ln and its amplitude becomes a sine wave (cosine wave) of nalpha. And the signals of a waveform level are gotten from the leads L1-Ln by averaging the output of the circuits 15 with an operation circuit 16. Thereby a gap between a magnetic record medium and a magnetoresistance effect device fluctuates so that the rotation of a disk may not be in the same plane and, even if an error is produced in the amplitude, a fluctuation part of the amplitude is canceled by averaging the signals of the leads L1-Ln. A detection error caused by the amplitude fluctuation included in the average of the A-phase signal and the B-phase signal, calculated with the circuit 16 are very small.

Title: Semiconductor laser device
Inventor: KOMAZAKI IWAO
IPC: H01S5/00
Filed: 1984-08-08
Abstract: PURPOSE:To obtain the high output having the excellent characteristics of oscillation spectrum and temperature and being capable of the control of a horizontal lateral figure by facilitating the control of impurity concentration and diffusion depth by diffusing the conductive type impurity in the region which will become a crystal plane vertical to a light-proceeding direction at least to the depth beyond the active layer. CONSTITUTION:A block layer 2 is formed on a conductive type semiconductor substrate 1 and a current narrowing part 3 is formed by zinc diffusion. Because the surface of impurity diffusion is of high concentration and crystallizability is deteriorated, the surface is etched and then a clad layer 4 is laminated and an active layer 5 of super lattice structure is formed. A clad layer 6 is laminated on the layer 5 and further a cap layer 7 is grown on that. By the high-temperature heat treatment and impurity diffusion, the refractive index becomes equal to that of the composition in which the refractive indexes of the semiconductors are levelled by the respective layer thickness. Accordingly, the carriers which is current-narrowed recombined in the active region to generate the light and the refractive index in both sides of the active layer becomes small by impurity diffusion so that the horizontal lateral figure can be controlled.
