Title: Vapor growth method for deformation quantum well semiconductor lasor
Inventor: FUKAYA KAZUO
IPC: C30B25/02
Filed: 1993-07-29
Abstract: PURPOSE:To enable execution of a stable operation at a high yield by a method wherein a growth temperature of an InGaAs deformation quantum well active layer to be formed by a crystal growth on a GaAs substrate is made in a specified temperature range and the growth temperature of a crystal growth layer after the formation of the active layer is made equal to the growth temperature of the active layer. CONSTITUTION:A GaAs buffer layer 2 is formed by a vapor phase epitaxial growth on an Si-doped GaAs substrate 1 and then an Al0.4Ga0.6As layer 3, a GaAs barrier layer 4, an In0.24Ga0.76As deformation quantum well layer 5 and a GaAs barrier layer 6 are made to grow sequentially. On the occasion when the InGaAs deformation quantum well active layer 5 is formed by a crystal growth, a growth temperature of this layer 5 is made in a range of 580 to 640 deg.C in order to obtain stability of an intake rate of In in a solid phase and in-plane uniformity of an emission characteristic. Besides, the growth temperature of a layer formed by the crystal growth after the active layer is made equal to the growth temperature of the active layer so as to obtain the deformation quantum well layer 5 having few defects.

Filed: 1980-12-29
Abstract: PURPOSE:To wire among electrode pads or a plurality of chips with good efficiency and high reliability, by positioning wiring boards provided with a designated wiring pattern on an IC chip in piles, and connecting the wiring pattern to pads on the chips. CONSTITUTION:For instance, wiring patterns of Au 8-11 are formed on a heat- resistant and transparent resin film 7 to shape wirings of IC chips. Electrode pads 8a, 8b-11b projected to each pattern end are provided to make a wiring board 1. The wiring board 1 is so positioned that the pads 8a-11 face to pads 3a-6b on the chips 2. A LASER beam or electron beam is irradiated on each pad of the wiring board. This makes the facing pads, for instance, 8a-3a and 8b-3b welded and fixed. The wiring pattern 8 connects between the pads 3a and 3b. The wiring among chips can be done similarly by connecting a plurality of chips to a single wiring board.

Abstract: PROBLEM TO BE SOLVED: To provide a fitting which can stably attach an object to a substrate in spite of the dimensional variation of the object by giving elasticity to one-side contact section of the fitting. SOLUTION: Firstly, a substrate is inserted into an object fitting 1 by bending the elastic part 3 of the fitting 1.

Therefore, the object can be attached stably to the substrate and, at the same time, the fitting 1 can be positioned surely. In addition, the assemblage of the object with the substrate also becomes easier.

Title: Optical disk device
Inventor: KATSUKI MANABU
IPC: G11B7/09
Filed: 1999-07-02
Abstract: PROBLEM TO BE SOLVED: To prevent a servo out-of-control state from continuing by controlling an actuator drive signal generation means so that the drive signal of focus or tracking can be retained for a position for causing a servo out-of-control when the number of retry operations exceeds a specific value at the same location. SOLUTION: In the retry operation when a servo out-of-control occurs, when a count is less than a specific value, the retry operation is made and information is recorded or reproduced by servo again. Also, when the count is equal to or more than a specific value, tracking and focus are corrected, and the position of a laser beam is detected on a disk. When the laser beam arrives at a position where the servo out-of-control has continuously occurred the drive signal of the actuator of tracking or focus is retained. When a servo error signal becomes stable, the retention operation of the drive signal of the actuator of tracking or focus is canceled.

IPC: D03D49/70
Filed: 1987-07-30
Abstract: PURPOSE: To obtain the subject device capable of precisely cutting wefts without cutting miss by forming a cutting area out of a polygon-shaped rotary blade, and a disk-shaped fixed blade, and catching the wefts diving in the area. CONSTITUTION: A space formed out of a polygon-shaped rotary blade 4 and a disk-shaped fixed blade 5, and surrounded by lines connecting A'-C' and C'-F' is constituted as a cutting area. When only the polygon-shaped blade 4 is rotated, the wefts diving in the neighbor of the lines connecting A-A and A-C' are precisely caught, guided to the crossing point C' of the rotary blade 4 and the receiving blade 5 and broken off because the lines connecting A-A and A-C' are straight lines. The remaining yarns after cutting the wefts 15 fall from the crossing point C' downward by the gravity, and hardly coil around a supporting shaft of the receiving blade 5 because the shaft is short and not rotated. Even if the yarns coil around the shaft, the yarns hardly provide a bad effect to the rotation of the rotary blade 4, and the cutting of the wefts is carried out precisely without cutting miss.

Filed: 1994-08-11
Abstract: PURPOSE:To improve the size precision and the mount precision of the dielectric resonator by forming the dielectric resonator coupled electromagnetically with a line on a board on which the line is formed through photo etching. CONSTITUTION:A microstrip line 2 is formed on a uniform dielectric board 1 being a high purity alumina board as typical board. Then a high dielectric material is adhered to the board 1 by coating or sputtering. Then a photo resist is coated and a desired photo mask is placed and exposed to remove selectively the photo resist. Then a high dielectric material of an undesired part is removed by using the remaining photo resist as mask through etching. When the photo resist is removed, the high dielectric material is formed to be a prescribed shape on the board 1. The procedure steps above are repeated till the high dielectric material reaches a desired height to form the dielectric resonator 3. The photo mask alignment is facilitated by simultaneously forming the line 2 and the dielectric resonator 3 to reduce the manufacture process.
