Title: Extremely high-speed thermal spraying device
Inventor: ASADA KAZUO
IPC: H05H1/42
Filed: 1988-04-26
Abstract: PURPOSE:To improve the adhesive strength and porosity of a thermal spraying material and to increase the hardness of the material surface by providing an accelerating gun consisting of a couple of conductive rails confronting each other with a plasma spraying material in between and a circuit for impressing a current on the rails. CONSTITUTION:The spark plug 17 of an explosion spraying gun 10 is ignited to explode a gaseous mixture of oxygen and acetylene. When the generated plasma spraying material 31 enters between the rails 22a and 22b of the accelerating gun 20, the switch 25 of the current impressing circuit 26 is closed, and a current flows from power source 24 through the rail 22a, the plasma spraying material 31, and the rail 22b. As a result, a magnetic field is generated in the material 31 by the current, and the material 31 is accelerated by the interaction of the current flowing through the material 31 and the magnetic field. Consequently, the adhesive strength and porosity of the material 31 are improved, and the hardness of the material surface is increased.

Title: Float to be used for fuel supplying device and liquid level gage
Inventor: NODA EISHIROU
IPC: B29C65/70
Filed: 1984-05-24
Abstract: PURPOSE:To prevent thoroughly the disengagement of a supporting arm and a float by mounting the supporting arm to an expanded compsn. subjected to preliminary crosslinking expansion molding and subjecting the compsn. to simultaneously integral expansion molding at the temp. below the temp. at which the resin supporting arm causes a thermal deformation. CONSTITUTION:One end of a preliminarily crosslinking expansion molded part 2 is inserted to the fitting part 4 of the preliminarily molded synthetic resin supporting arm 1 and thereafter the assembly is loaded into a metallic mold for a product and is subjected to simultaneous integral expansion molding by heating (at the temp. below the temp. at which the arm 1 causes a thermal deformation, for example, 170 deg.C and for about 30min) under the pressurization (about the pressure under which the metallic mold does not open). The steam of the pressurizing press is thereafter changed over to cooling water to cool the molded part for about 10min. When the pressurizing press and the metallic mold are opened upon solidification of the product, the float product molded integrally with the float 6 having the closed cell structure and the arm 1 is obtd. The disengagement of the supporting arm and the float is thus thoroughly prevented.

Title: Metal halide lamp and floodlight using it
Inventor: KAWASHIMA HIROMICHI
IPC: H01J61/30
Filed: 1993-04-30
Abstract: PURPOSE:To keep high the maintenance factor of luminous flux by keeping the tube wall of an arc tube away from portions where temperature is high so as to restrain the temperature rise of the tube wall, and restraining reaction of quartz glass with a metal halide so as to prevent devitrification of the quartz. CONSTITUTION:A floodlight 60 is used with the optical axis O2-O2 of its reflector 2 pointed in a roughly horizontal direction, and a short arc metal halide lamp 1 is horizontally lighted. The lamp 1 is connected to a DC power supply 50 and lighted by DC while the load on a tube wall is as high as 63W/cm. In this case, devitrification of the wall of a light emission tube can be prevented by satisfying I/D O0.6A/mm wherein the lamp current is IA and the maximum bore of the arc tube 20 in the direction perpendicular to a line connecting electrodes 21, 22 is Dmm. Since the wall of the light emission tube is kept away from an arc by I/D being 0.6 or less, the temperature rise of quartz is restrained and thus the rate of reaction of the quartz with the metal halide is reduced.

Title: Manufacture of single crystal thin-film member
Inventor: NISHIMURA HITOSHI
IPC: H01L21/3065
Filed: 1989-04-24
Abstract: PURPOSE:To obtain a thin-film having high rupture strength and arbitrary film thickness by partially exposing an epitaxial layer, etching the exposed region of the epitaxial layer through reactive ion etching and bringing the exposed region to specified thickness. CONSTITUTION:A thin-film composed of a second conductivity type epitaxial layer 2 is etched through reactive ion etching, and the second conductivity type thin-film having desired film thickness is shaped. Consequently, the thickness of the thin-film acquired does not depend upon the thickness of a semiconductor substrate 1, and can be determined by the thickness of the epitaxial layer 2 and the conditions of etching of reactive ion etching. Since the film thickness of a section to be removed through an etching process by the reactive ion etching is reduced, the variation of the thickness of a single crystal thin film 7 obtained is lowered extremely, thus avoiding the local-concentration of stress when pressure is applied and the thin-film 7 is fluctuated. Accordingly, the multikind single crystal thin-film having high rupture strength and arbitrary film thickness is acquired easily.

Title: Bolt for hollow part
Inventor: IKUTA KAZUICHI
IPC: F16B35/06
Filed: 1995-04-27
Abstract: PURPOSE: To prevent engaging generation of a supporting member even if a V-shaped recessed part is formed on the back surface side of a hole, and prevent an incomplete fixing condition and failures of a wall surface and a building material by forming a corner part which is brought in contact with the wall surface and the like on the back end side of the supporting member on a missed curving surface or an inclining surface. CONSTITUTION: A hollow part bolt 1 consists of a bolt 2 and a supporting member 3 installed on one end side, and it is installed so as to be rotatably at an angle of 90 deg. or more in the supporting member 3. When it is slipped out from a hole C1 , the top end side of the supporting member 3 is rotated in a clockwise direction around a shaft 10. Since a corner part is formed on a missed curving surface 11 or an inclining surface, the curving surface 11 is not engaged with a recessed part D at the time of rotation of the supporting member 3. When a nut 12 is fastened, the curving surface 11 abuts on the recessed part D, and then the supporting member 3 is slid and laminated along the back surface of a building material B. It is thus possible to fix an apparatus material to the building material B by the nut 12 and the supporting member 3 which is crossed with the bolt 2.

Abstract: PURPOSE:To decrease the noise caused by electromagnetic force for working an inclined magnetic field coil without complicating particularly the constitution, and to decrease the discomfort of a patient. CONSTITUTION:An inclined magnetic field generating coil part 14 provided on the inside of a superconductive magnet being a main magnet for forming a static magnetic field is provided with a roughly cylindrical bobbin 20, and inclined magnetic field coils 21x...21z (three coils of x, y and z coils) embedded in this bobbin 20. As for wall thickness of the bobbin 20, the end part is set to the same prescribed thickness as conventional, and as the outside peripheral surface side advances to the center part from this state, it becomes thicker linearly. That is, a cross sectional shape in the axial direction on the outside peripheral surface of the bobbin 20 draws a crest shape in which the center in its axial direction is the apex. Therefore, as it approaches the center, the deflection rigidity becomes high. In such a way, the resolution of a diagnostic image is improved.
