Title: Semiconductor laser device
Inventor: ISHIKAWA MAKOTO
IPC: H01S5/00
Filed: 1986-01-24
Abstract: PURPOSE:To manufacture a low threshold and high efficiency buried semiconductor layer in good reproducibility and high yield by disposing a contracted portion varying in a forward mesa face from a reverse mesa face in a GaAs substrate, and forming an AlGaAs grown layer of a reverse mesa face preferably moistened all with solution. CONSTITUTION:An N-type Al0.4Ga0.6As clad layer 2, an Al0.1Ga0.9As active layer 3, a P-type Al0.4Ga0.6As clad layer 4 and a P-type Al0.15Ga0.85As electrode layer 5 are sequentially grown on an N-type GaAs substrate 1 by first liquid epitaxial growth. Then, with SiO2 as a mask only a light emitting unit remains by chemical etching to etch in a reverse mesa shape. In this case, a contracted portion 11 varying from reverse mesa to a forward mesa is so etched as to depend on the substrate 1. Further, a burying growth is executed by an N-type Al0.4Ga0.5As buried layer 6 to surround the light emitting unit by second liquid epitaxial growth. With an SiO2 film 8 as a mask a P-type diffused layer 7 is eventually formed to form a P-type electrode 9 and an N-type electrode 10.

Title: Method for improving blood circulation and device therefor
Inventor: NAKATANI SOJI
IPC: A61H33/02
Filed: 1994-02-08
Abstract: PURPOSE:To obtain a blood circulation effect as good as that of bathing in a short time by discharging the hot water containing carbon dioxide dissolved of a specific concentration like a shower from many pores. CONSTITUTION:When hot water is taken in a hollow thread film 2 from a hot water takein port 4 of a dissolver 11 through an introducing tube with a flow rate detector 14, the carbon dioxide passes the hollow thread film 2 from outside and is dissolved so as to reach the concentration of 60ppm or higher and lower than 3000ppm. The obtained carbon dioxide solution is ejected from an take-out port 5 and ejected like a shower from a nozzle 13 with many pores. The carbon dioxide is supplied from a cylinder 12 through a piping to the dissolver 11. An opening/closing valve 15 in the piping is opened and closed based on the detection signal of the flow rate detector 14. In short, when the hot water does not flow, the opening/closing valve 15 is closed. A pressure reducing valve 16 is attached to the cylinder 12 to reduce the pressure in the cylinder 12 down to a prescribed pressure.

Title: Dropout compensator
Inventor: MITANI HIROSHI
IPC: H04N5/94
Filed: 1987-01-23
Abstract: PURPOSE:To shorten a time necessary for the correction action for a demodulated signal by providing a monostable monomultivibrator which is triggered by an output signal from a dropout detection means and an adding means to add a reproduced signal and an output signal from said monomultivibrator with each other. CONSTITUTION:A dropout detector 101 outputs a dropout detection signal after the lapse of a detection delay time td. The monostable monomultivibrator 102 is triggered by said dropout detection signal, and outputs an output pulse (c) of a time duration tc. And this time duration tc of an output pulse is so selected that the trailing edge of the pulse comes in a normal position, and further, the duration must be longer than the inverse number of the maximum input frequency of an FM demodulator 104. Therefore, the detection delay time td needs to be sufficiently shorter than the half period of a carrier signal so that the time duration of an output pulse form the monostable monomultivibrator 102 can satisfy said condition. The adder 103 adds the output signal (c) from the monomultivibrator 102 with a reproduced signal (b) to compensate a pulse that dropped out.

Title: Tablet for resin flow analysis and method for resin flow analysis using it
Inventor: YAMAGUCHI TATSUYOSHI
IPC: B29B9/12
Filed: 1996-01-31
Abstract: PROBLEM TO BE SOLVED: To make it possible to visually recognize the flowing behavior of resin within a metal mold and analyze resin flow with reliability by incorporating color markers in a transparent, columnar resin tablet in specified positions. SOLUTION: In an area where color markers are scattered about, colored resin powders 1b (red), 1c (blue) and 1d (green) move to positions A, B and C, respectively as the position of the flow front of transparent resin is drifted. The flow of resin within cavity can be continuously monitored in real time by picking up the image inside a metal mold using a CCD camera at this time Further, how the resin moves in the cavity and how its curing is completed are made quite obvious by analyzing the recorded image and tracking a specific marker that enters the cavity frame by frame. This greatly helps clear up the causes of any molding defect, improves the productivity of molded products, and enables good maintenance and control of molding quality.

Title: Magnetic head assembly and magnetic disk device
Inventor: TAKAHASHI KENJI
IPC: G11B21/21
Filed: 1998-01-28
Abstract: PROBLEM TO BE SOLVED: To stably float a magnetic head assembly by restricting the displacement of a magnetic head with respect to a suspension at the restriction region constituted with a positional relation having a gap with the head when the head is displaced to make the rigidity of the outside of surface direction of a suspension gimbal part low and the rigidity of the intra-surface direction high. SOLUTION: In a normal floating state, since magnetic head slider restricting parts 7 are not in contact with a magnetic head 1, they do not affect the floating of the head. At the time of a seeking operation and an attraction releasing operation, a suspension gimbal part 5 is bent in an outside of surface direction and the head 1 and the restriction parts 7 are brought into contact to suppress the deformation of gimbals. Then, the deformation of the gimbals due an external force is prevented by making the gap between the head 1 and the restricting parts 7 in the normal floating state to be within the elastic deformation of the intra-surface direction of the gimbal part.  The gimbal part 5 has only a function supporting the head 1 flexibly and secures its strength with restricting parts 7 and supports the head 1 flexibly at the outside of surface direction and, moreover, obtains a magnetic head assembly having high strength at the intra-surface direction.

Title: Optical exclusive orarray circuit
Inventor: TSUDA HIROYUKI
IPC: H04B10/00
Filed: 1991-01-14
Abstract: PURPOSE:To provide the optical exclusive OR circuit which can make an exclusive OR operation between two light input signals. CONSTITUTION:Two sets of the light beams propagating in space or in waveguides or in optical fibers are formed as 1st to 4th sets of light beams and are guided to an optical inverter element array constituted of a 1st set of an optical inverter element 1V1k and a 2nd set of an optical inverter element 1V2k. The optical inverter element array is inputted with these 1st to 4th sets of the light beams and output these beams by lowering the light transmittance or light reflectivity thereof. The output light beams are multiplexed by an optical output section OT and are outputted. Consequently, the exclusive OR operation of two sets of the light signals is eventually executed at a high speed by effectively utilizing the wide band characteristics of the optical elements and since the circuits are constituted of only the elements having the inverter functions, the computation of the exclusive OR by one stage of operation is executed and the need for obtaining synchronization between the elements is eliminated. In addition, the circuitry is simplified and the integration of the circuits is facilitated.
