Title: Production of alloy powder for dental amalgam
Inventor: KAJI HIROYUKI
IPC: B22F1/00
Filed: 1980-06-27
Abstract: PURPOSE: To improve the characteristics of dental amalgam of Ag-Sn-Cu by mixing an alloy contained with In to prevent sulfurization of Ag and an alloy added with Sn to delay the curing time of an Ag-Cu eutectic alloy at specific ratios thereby forming the raw material alloy for said amalgam.  
     CONSTITUTION: As the dental amalgam alloy, a mixture of the particles of ≤44μ made by spraying the molten alloy comprising 60W72% Ag, 20W30% Sn, 1W9% Cu, 2W10% In and <0.5% Zn and the alloy particles comprising 66W72% Ag,  23W32% Cu and 1W10% Sn at ratios of 55W15% is used. Since the former alloy  contains In, sulfurization blackening of Ag does not occur, and since the latter alloy permits controlling the curing time of an Ag-Cu eutectic alloy by controlling an Sn content, the alloy powder for dental amalgam which permits easy filling operation to teeth and has superior physical properties is obtained.

Title: Manufacture of heat exchanger
Inventor: SHIMIZU FUJIO
IPC: B23K3/06
Filed: 1989-04-07
Abstract: PURPOSE:To firmly braze a fin and a tubular body by making a through-hole in a fin and forming an insert-through hole by extending the peripheral edge of the through- hole vertical to the fin so as to make a flange, inserting the tubular body into the insert-through hole, and also, heating and melting a brazing filler metal and joining it. CONSTITUTION:A circular hole 4 is made in a fin 1 made of a copper alloy by using a punch. Subsequently, a cylindrical flange 10 is formed by using a die 6 and a projecting punch 8. Also, the diameter of the circular hole 4 is expanded, and an insert- through hole 14 for allowing a heat exchange tube 12 to pass through is formed. The fin 1 in which the insert-through hole 14 is made is fitted into a projecting base 18 in which a groove 16 is formed, and a plate-like notch die 20 is depressed in the direction as indicated with an arrow C by aligning it with the groove 16. An L-shaped notch 22 is formed extending over the flange and the fin. By arranging plural fins 1 in parallel and allowing the heat exchange tube 12 to pass through the insert-through hole 14, a heat exchanger is brought to temporary assembly. By allowing a brazing filler metal 26 to pass through a void 28 and heating the heat exchanger, the brazing filler metal is melted. In such a way, the heat exchange performance of the heat exchanger is improved, and also, the quality of the heat exchanger can be improved.

Title: Wiring system with erroneous wiring detecting function
Inventor: HIRAUMA HIDEYOSHI
IPC: G01R31/02
Filed: 1983-05-20
Abstract: PURPOSE:To elevate the working efficiency by a method wherein information on wired points to a wrapping tool from a tester for display and an error display is performed immediately when erroneous wiring is generated. CONSTITUTION:A wiring information is fed to a wrapping tool 5 from a tester 7 with a magnetic tape 70 storing a terminal number information and indicated on a digital display section 50. A worker wraps a wire 4 between terminals according to the display. The tester 7 detects any erroneous wiring automatically and sounds a buzzer to inform of the same. Any erroneous wiring in the course of the wiring can be repaired immediately by a warning thereby reducing the man-hours of the wiring and the repair drastically. This eliminates the wiring diagram and the wiring testing is regarded to be ended upon the finishing of the wiring work.

Title: Terminal device for high frequency device
Inventor: AISAKA MAKOTO
IPC: H01P5/08
Filed: 1988-04-11
Abstract: PURPOSE:To reduce the transmission loss and to eliminate the need for a matching circuit by fitting a core line perpendicularly to a strip line sub board provided close to a metallic case with a coaxial connector fitted thereto and fitting the board perpendicularly to a main printed circuit board. CONSTITUTION:The core wire 3 of a coaxial connector 1 is inserted perpendicularly to the strip line sub board 4 and connected to the strip line in terms of a high frequency. The distance between the coaxial connector 1 and the strip line sub board 4 is selected to be a small value with respect to the wavelength of a UHF or SHF wave concretely to be 1-5mm. Moreover, the characteristic impedance of the strip line on the board 4 is selected to be the same as the characteristic impedance of the coaxial connector 1. Thus, since the inductance component of the coaxial connector 1 is negligibly small, impedance matching is applied between the coaxial connector 1 and the strip line of the strip line sub board 4. Thus, the transmission loss is small and no matching circuit is required because of the provision of a broad band frequency characteristic.
