Title: Semiconductor laser amplifier
Inventor: MAKINO TOSHIHIKO
IPC: H01S5/00
Filed: 1988-05-10
Abstract: PURPOSE:To amplify an incident laser light perpendicularly to the face of a semiconductor substrate and to output it perpendicular to the substrate by forming both end faces of an optical guide wave including an active layer at approx. 45 deg. to the face of the substrate, and forming input/output light reflecting face. CONSTITUTION:Both end faces 10, 11 of an optical guide wave having incident and emitting sections of a light perpendicular to the face of a semiconductor substrate 1 and including an active layer 3 are formed at an approx. 45 deg. to the face of the substrate 1 to form an input/output light reflecting face. An input laser light enters perpendicularly to a cap layer 5, totally reflected on a first totally reflecting section 12 perpendicular to the layer 3 of the end face 10 formed at 45 deg. to the layer 5, and propagated in the layer 3. It is again totally reflected at a second totally reflecting section 13 crossing the layer 3 of the end face 11 formed at 45 deg. to the layer 5, and radiated oppositely to the incident direction from the layer 5. Thus, input/output light becomes perpendicular to the face of the substrate of a semiconductor laser.

Title: Spraying method for asphalt emulsion
Inventor: MAEDA TOSHIAKI
IPC: E01C7/35
Filed: 1998-04-23
Abstract: PROBLEM TO BE SOLVED: To instantaneously decompose an asphalt emulsion and separate water to form asphalt film by bringing a light metal electrolytic decomposer into contact with a cationic asphalt emulsion using an emulsion mainly composed of amine by spraying the decomposer. SOLUTION: An asphalt emulsion is sprayed on road base, a binder course, or a surface course. After it has been sprayed or immediately after that, a decomposer is sprayed on the asphalt emulsion to bring the decomposer into contact with the emulsion. Then, the asphalt emulsion is decomposed after about 1-5 min from the contact with decomposer and bleeding water is brought and further, asphalt film is formed. Asphalt or the like is emulsified with an aqueous solution of an emulsifier in a colloid-mill or the like to prepare the asphalt emulsion. Meanwhile, a light metal electrolyte is used for the decomposer. In this way, the construction time can be greatly reduced and since the decomposer has no influence to human bodies and it can be used as an aqueous solution, the workability is excellent as an effect.

IPC: A61B8/02
Filed: 1999-04-21
Abstract: PROBLEM TO BE SOLVED: To automatically execute optimum positioning of a pulse wave probe at a time of attachment and after the attachment of a pulse wave detector. SOLUTION: Ultrasonic signals from all pairs of a plurality of transmitting piezoelectric transducers 101A-101D for oscillating ultrasonic waves to an arteria part and a plurality of receiving piezoelectric transducers 102-102D for receiving ultrasonic waves from the arteria part is obtained. Before or during detecting the pulse wave, the optimum combination of the piezoelectric transducers for transmission and receiving for a measurement of pulse is determined based on the strength of the obtained ultrasonic signal. Then, the transmitting and the receiving piezoelectric transducers are allowed to conduct oscillation and reception by the determined optimum combination. Thus, the pulse wave can be detected and measured while automatically determining the optimum position of the pulse wave probe.

Title: Extrusion molding method and device for material composed of thermoplastic polymer
Inventor: HARORUDO KIISU SORUTAA
IPC: B29C48/09
Filed: 1989-05-02
Abstract: PURPOSE: To enable a consecutive molding of an extrusion profiles having excellent characteristics by rapidly compacting and extruding a material comprising a thermoplastic polymer and forcing the material through an aperture in die means so as to extrude it therethrough, the extrusion being made at below the melting point of the material. CONSTITUTION: As a wheel 11 rotates, a material 18 in a groove 13 is carried forward by a frictional drag of walls of the groove 13 and forced against an abutment portion 15. Pressure is thus generated in the material 18 so that it is rapidly compacted and forced through an orifice 16. This causes rapid heating of the material 18 and longitudinal orientation in the orifice 16. The heat sink provided by a shoe member 14 cools the material 18 almost immediately as the material 18 passes through the orifice 16 to an extent such as to substantially retain the desired longitudinal orientation in the extruded material 18.

Title: Concentrating method for sludge
Inventor: ITOU KAZUYUKI
IPC: C02F11/12
Filed: 1979-09-06
Abstract: PURPOSE: To control an increase of nitrogen concentration in separated water, by adding nitrate and organic carbonaceous compound to the sludge generated by the waste water treatment and promoting the denitrifying treatment by the denitrifying bacteria and then, floating and concentrating the sludge by generated N 2  gas effectively.  
     CONSTITUTION: Nitrate suce as NaNO 3  etc. and organic carbonaceous compound such as glucose etc., are added to the sludge generated at the time of treating waste water by activated sludge method and denifrifying reaction is promoted by denitrifying bacteria in the sludge. It is preferable to add said nitrate in such an amt. that the nitric acid type nitrogen in the suldge exists at about ≥30ppm. Also, treating condition other than adding nitrate and organic carbonaceous compound, is preferable to be in the normal condition of denitrifying reaction, for example, 0W50°C, especially 25±5°C, 6W8pH. Next, the sludge having a high concentration of solid matter, which is floated by generated N 2  gas, is separated by the normal solid- liquid separation means and on the one hand, separated liquid is returned to the purifying process. Further, deterioration of quality of treated water, is restrained by decreasing the concentration of NO 3   -  in the separated liquid, since the NO 3   -  can't be decomposed in the purifying process.

Title: Cd player capable of higher fidelity reproduction
Inventor: OHARA KAZUO
IPC: G11B17/028
Filed: 1998-03-19
Abstract: PROBLEM TO BE SOLVED: To prevent scattered laser light from being incident upon a pickup and to accurately reproduce a digital signal by indenting grooves in a discoid board having the same size as a clamping area of the CD, which are gradually larger in depth toward the inner periphery of the discoid board, fitting smooth metallic reflecting films to the bottom surfaces of the grooves respectively and closely fitting this discoid board to the clamping area of the disk. SOLUTION: Two grooves, each in a shape of increasing its depth toward the inner periphery at an inclined angle of about 20 deg. are indeted in the surface of the clamping area of a disused disk by using a circle cutter, and the surfaces of the inclined grooves are polished and smoothened. Subsequently, the smoothened surfaces are vapor-deposited with aluminum, and a part of the clamping area is separated away to make the discoid board 3. This discoid board 3 is fitted to a clamper 1. Consequently, the scattered laser light that is incident upon the clamping area of the CD is released outside the CD, and hence a digital signal can accurately be reproduced to approach an expected stereo effect.

Title: Compressor
Inventor: KUBO MASAHIRO
IPC: F04C23/02
Filed: 1984-06-06
Abstract: PURPOSE:To promote miniaturization speedfulness in a compresor as well as to aim at reduction in axial turning torque and vibration, by having an eye to characteristic frequency in a whole system consisting of a rotation system, a bearing, a bearing supporter and so on, and thereby raising a degree of rigidity in parts other than the rotation system in the whole system. CONSTITUTION:A rotary shaft 1 is one-sidedly supported by an upper bearing 4 and a lower bearing 6, respectively. In this case, axial turning torque comes to minimum at a time when rotational frequency si 5/8 of characteristic frequency on a whole system. Therefore, the characteristic frequency of the whole system is set to the range of 1.5-1.7 times over the maximum operation frequency. If so, secondary and primary resonances both are preventable. In addition, an apparent vibration of the rotary shaft 1 at a supporting point A is dependent upon how about rigidity in the upper bearing 4, a cylinder 5, a joining part B and a vessel 7. Accordingly, rigidity in the joining part B is raised up whereby the characteristic frequency of the whole system is heightened, thus it is adjustable to the proper range.
