Title: Manufacture of semiconductor device
Inventor: KIMURA SHINICHIROU
IPC: H01L29/78
Filed: 1983-12-26
Abstract: PURPOSE:To enable forming a film which is not inferior in the interfacial characteristics to an insulation film formed at high temperature treatment at a comparatively low temperature by using a microwave plasma oxidization equipment. CONSTITUTION:In a gas which contains oxygen maintained at 1X10<-3>-1Pa as a constituting element, a microwave and a magnetic field of 100 gauss or more field intensity are doubly applied and a plasma which contains active elements such as atoms and molecular ions generated using electronic cyclotron resonance is irradiated on silicon. For example, after a gate electrode 22 is processed, a semiconductor element is treated with plasma oxidation. If oxygen plasma treatment is carried out for a substrate at a temperature of 700 deg.C for 1hr with power of 140W applied to a plasma of oxygen gas pressure 2.7X10<-2>Pa, an oxidized film 21 which is not covered with the gate electrode 22 is increased and the reduction of a gate oxidized film after the gate electrode processing can be compensated.

Title: Nonlinear optical element
Inventor: TOYAMA WATARU
IPC: G02F1/35
Filed: 1990-09-17
Abstract: PURPOSE:To enable secondary higher harmonic generation by using a simple optical material and to modulate SHG intensity by the application of a voltage by charging nematic liquid crystal which has dimer forming ability between two glass substrates which have electrodes. CONSTITUTION:This nonlinear optical element form a liquid crystal panel A by charging the nematic liquid crystal 20 which has the dimer forming ability between the two glass substrates with the electrodes having oriented films 22 adhered on one-surface sides. It is considered that a liquid crystal panel like this generates SHG since a dimer is separated into monomers by a radical, etc., in the oriented film and the separated monomer liquid crystal molecules 26 are adsorbed to the boundary surface of the oriented film 24 to form an electric double layer although liquid crystal molecules and the oriented film operate on each other on the boundary surface of the oriented film 22 in the liquid crystal panel A. This layer is a sort of dielectric, so the polarization can be inverted by inverting the polarity of the external applied voltage. This polarization inversion is used to impose SHG intensity modulation with the voltage. A representative example of the nematic liquid crystal having the dimer forming ability is 4-n-pentyl-4'-cyanobiphenyl.

Title: Butt welding method for metallic tube or bar
Inventor: SATO YUICHI
IPC: B23K37/053
Filed: 1996-09-13
Abstract: PROBLEM TO BE SOLVED: To join a metallic tube or a bar without a devriation of material at the time of a butting and without horizontal sliding after a butting, in diffusion welding in which these materials are abutted on each other in a longitudinal direction with an insert metal interposed in a joining face of materials. SOLUTION: The two materials are restrained horizontally by stretching plural bar-like supporting bodies 6 across the joining faces 4. In the case of joining metallic tubes, they are horizontally restrained by providing a projection in plural places in the circumferential direction of one joining face 4 and a recess to fit with each projection in the other. Similarly, in the case of metallic bars, they are also horizontally locked by forming a projected part on one joining face and a recessed part on the other. Consequently, excellent diffusion welding can be carried out through a simple structure. It is inexpensive and easy compared with other joining means such as MIG, TIG and pressure welding; it is suitable for joining steel tubes, bars, etc., in the field pipe installation for an oil well or in various kinds of construction sites.

Title: Heat exchanger
Inventor: ISHIKAWA ATSUYUMI
IPC: F28D1/047
Filed: 1989-09-20
Abstract: PURPOSE:To reduce in size a heat exchanger, to reduce ventilation resistance and to improve a heat exchanging rate by raising the air inlet side end of a flat tube higher than an outlet side end, and aligning the tubes substantially in an L or arc shape. CONSTITUTION:A heat exchanger 2 is composed of an upper heat exchanger unit 6 and a lower heat exchanger unit 7, and a plurality of flat tubes 11, 15 are disposed substantially in an L or arc shape. Thus, heat exchanging area can be increased even if the size of the exchanger is suppressed to a small size. Accordingly, a housing for containing the exchanger can be reduced in size. Further, since the tubes are all so inclined as to raise an air inlet side end 19 higher than an outlet side end 20, the air flowing among the tubes flows downward, and drain water 25 adhered to heat exchanging fins 12, 16 among the tubes tends to easily flow down along the tubes. Therefore, its heat exchanging efficiency can be improved.

IPC: B60J10/82
Filed: 1984-11-17
Abstract: PURPOSE:To prevent a hinge from rattling, by applying a resilinet load to the engagement sections of hinge halves which are engaged together, with the use of an auxiliary hinge spring that abuts against both hinge halves. CONSTITUTION:When a hinge is removed, the leg 30 of a hinge spring 26 enters in a retainer 38 with a certain degree. Upon attachment of a cover 34 the longer legs 30 of the hinge spring 26 serves as a guide surface of a hinge pin 36. When the hinge pin 36 reaches a receiving surface 37, the hinge spring 26 is compressed as shown in the drawing. Therefore, the hinge spring 26 applies a component of force which is directed upward reaward, to the hinge pin 36 which is therefore pressed against the receiving surface 37 by the force component. Such depressing force acts upon the hinge pin 36, irrespective of the positions of the cover 34, that is, close, elevated and intermediate positions so that noise of the hinge may be restrained.

Title: Amorphous silicon type photoconductor
Inventor: WAKITA KAZUKI
IPC: G03G5/08
Filed: 1987-09-29
Abstract: PURPOSE:To attain excellent photoconductive characteristics and to enhance resistivity by specifying the activation energy of a dark conductivity.

Title: Injection compression molding method
Inventor: TANAKA YUJI
IPC: B29C45/50
Filed: 1997-09-10
Abstract: PROBLEM TO BE SOLVED: To easily correspond even with a design of a wide range of a thick- walled part by low gas pressure and to stably mold the thickwalled part having sink free appearance by allowing a resin to flow backward from the resin gate provided in the vicinity of a thickwalled rib part at a time of mold closing compression to allow gas to flow to the periphery of the thick-walled rib part. SOLUTION: In such a state that a mold 2 is slightly opened, a molten resin 3 is injected into a cavity 1 from the resin gate provided in the vicinity of a thick-walled rib part 11 by an injection nozzle 20. Next, compressed gas is injected through an ejector pin 6 and the mold 2 is closed and compressed subsequently to allow the resin 3 to flow backward into the cavity 1 from the resin gate. After mold closing compression is completed, the mold is held for a predetermined time and the mold 2 is opened to take out the molded product 10. Therefore, since the resin pressure of a rib part 11 can be effectively lowered, the gas can be certainly guided to the periphery of the rib part 11. By this constitution, resin spreading effect in compression molding is not sacrified and the rib part 11 can be selectively pressed by using low pressure gas.

Abstract: PURPOSE:To prevent the overlap of a turn-on state between each timing pulse by generating the timing pulse by deriving an AND condition of plural parallel outputs outputted, based on plural clock signals of the same frequency whose phases are different. CONSTITUTION:By synchronizing with clock signals ST1, ST2, a first and a second shift registers 11, 12 execute a shift operation, respectively, and output each parallel output Q1a-Q1d, Q2a-Q2d. Each parallel output thereof Q1a-Q1d, Q2a-Q2d is inputted to an AND arithmetic part 3, and the AND arithmetic part 3 derives an AND condition by each AND element 3a-3d and generates timing pulses T1-T4. As for these timing pulses T1-T4, its contents are determined by cycle width of clock pulses ST1, ST2, a phase difference and holding data of each register 11a-11d, 12a-12d. In such a way, a time difference is generated in each rise time of the timing pulses T1-T4, and it can be prevented that a turn-on state occurs simultaneously between each of each timing pulse T1-T4.
