Title: Production of cylindrical fiber reinforced metallic composite material
Inventor: KITAMURA ATSUSHI
IPC: B22D19/14
Filed: 1987-04-10
Abstract: PURPOSE:To permit extremely easy removal of a core when the core is cooled after production by arranging the innermost layer of an assemblage of reinforcing fibers in such a manner that the direction of the reinforcing fibers is in the peripheral direction of the core. CONSTITUTION:The assemblage 2 of the reinforcing fibers is disposed around the round bar-shaped core 1 in a metallic mold 3. The innermost layer 4 of the assemblage 2 is so arranged that the reinforced fibers are directed in the circumferential direction of the core. The reinforcing fiber layer 5 is arranged on the outside of the layer 4 according to applications, etc. A melt 6 of a metal to serve as a matrix is then poured into the mold 3 and is pressurized by a plunger 7 by which the molten metal is impregnated into the assemblage 2 and is solidified. The mold 3 and a base 8 are separated, upon solidification of the molten metal 6, and an FRM is taken out together with the core 1 from the mold 3. The core 3 is then removed. A difference in the coefft. of thermal expansion between the core 1 and the FRM in the radial direction is increased and the removal of the core 1 is facilitated.

Title: Semiconductor device
Inventor: ADACHI GENICHI
IPC: H01L23/52
Filed: 1978-07-21
Abstract: PURPOSE: To restrain corrosion of an Al wiring by covering it with a titanium alloy film.  
     CONSTITUTION: An Al wiring 3 is formed on a Si substrate 1 through an oxidized film 2, and a Ti-W film 4 is formed on the wiring 3. Then a PSG film 5 is formed and an opening is formed where a projected electrode is made. A Cr film 6 and a Cu film 7 are formed in series by means of vacuum vapour coating. Then a photoresistor film 8 is formed except for the area where the projected electrode is made; and with this film 8 as a mask, an Au layer 9 is selectively electoplated to form the main section of the projected electrode. Then the photoresistor film 8 is removed, and the both Cu film 7 and Cr film 6 are etched one by one with the Au layer 9 as a mask. Thus by covering the Al wiring by the Ti alloy film, corrosion of the Al is  restrained effectively; and as a result, the wiring can be used in a high temperature  and high humidity atmosphere.

Title: Device for detecting abnormal member carried on steel plate carrying line
Inventor: NITTA KAZUHIRO
IPC: B21B37/28
Filed: 1997-04-08
Abstract: PROBLEM TO BE SOLVED: To provide a detection device free from any secular degradation, wear or breakage by measuring the thickness of a center part of a steel plate by a non-contact type center part displacement meter to judge presence/absence of any lapped part of steel plates, measuring the displacement of a side part by a side part displacement meter, and combining both measurement results to judge presence/absence of any warp of the steel plate. SOLUTION: An upper center part displacement meter 12A and a lower center part displacement meter 12B measure the thickness of a center of a steel plate 1 to detect presence/absence of the lapping of the steel plate 1. The upper center part displacement meter 12A detects the warp in the longitudinal direction of the steel plate 1. A pair of side part displacement meters 13A, 13B measure the displacement of the side parts of the steel plate 1. The difference between the indicated value by the upper center part displacement meter 12A and the indicated value of the side part displacement meters 13A, 13B is operated to detect the warp in the width direction of the steel plate 1.  An abnormal plate judging means 16 compares the detected warp in the longitudinal direction or the detected warp in the width direction with the preset allowable value in a plate information setting means 17, and judges to be abnormal when the detected value exceeds the allowable value.

Filed: 1999-03-30
Abstract: PROBLEM TO BE SOLVED: To provide a wire clamping and cutting device to be used in clamping and cutting a wire, reduced in size, simple in structure, and easy in adjustment of a position for fixing a cutting edge. SOLUTION: An upper clamping part 60 is constituted by providing a retaining member 122 retaining a cutting edge part 124 with a pressing part 136 supported by the retaining member through a plate spring part 140. The plate spring part 140 is capable of bending deflection in such a direction as to separate from the receiving surface 166 of a lower clamping part 62 by the deflection amount equal to the relative displacement amount of the cutting edge part 124 and the pressing surface 146. Thus, the plate spring part 140 is subjected to bending deflection when the pressing surface 146 of the pressing part 136 which is positioned so as to face the receiving surface 166 is pressed against the receiving surface 166, so that the pressing part 136 is displaced relatively in such a direction as to approach the retaining member 122.  The cutting edge part 124 retained by the holding member 122 so as to be fixed at a relative position is displaced toward the lower supporting part 62 relatively to the pressing part 136, so that a cutting edge 154 is protruded from the pressing surface 146.

Filed: 1979-07-13
Abstract: PURPOSE: To make the mounting of a strip ring easier, by hardening to a desired hardness only the bottom portion of a groove, to which the strip ring is mounted, through a use of a heat source in which electrodes are not brought into connection but a high energy density is produced.  
     CONSTITUTION: A nontransfer arc discharge as a heat source of a high energy density makes use of a plasma jet 70 which is produced by connecting an in-torch central electrode 71 to a negative electrode and also connecting a nozzle 72 surrounding in an electrically noncontacting fashion the central electrode 71 to a positive electrode, and then by blowing an inert gas 8 such as argon against an arc produced between both electrodes. Since an item 1 to be heated is not connected to the electrodes, the plasma jet 70 of the high energy density is attracted toward the item 1 without diversion and can perform a prompt local heating of a bottom portion 51 of a groove 5. Upon suddenly quenching the bottom portion 51, the bottom portion 51 can be hardened to a desired degree of hardness. Acconrdingly, without deforming the bottom portion 51, a strip ring (not illustrated) can be smoothly mounted into the mounting groove 5.

Abstract: PURPOSE:To constitute a simple structure to prevent the occurrence of floating electrode in such a manner that the number of parts is reduced by a method wherein a resilient member is brought into direct contact with a second operation shaft and the drive lever of a drive mechanism part brought into a ground touching state and the second operation shaft are electrically interconnected. CONSTITUTION:The insulating rod 4 of a vacuum opening closing device electrically interconnects a drive lever 31 and a second bolt 44 in a way that the linear part 70a of a coil spring 70 is brought into direct contact with a second bolt 44. Thus, the second bolt 44 is brought into ground touching state by the drive lever 31 in spite of a vacuum opening closing device being in an opening closing state and prevented from forming a floating electrode. Further, the coil spring 70 is arranged to the periphery of a drum part 44c protruded from a bottom 40b by a given length between the bottom 40b of the recessed part 40a of an insulating member 40 and a contact piece 45 positioned by the stepped part of a second operation shaft (bolt). Thus, the initial length of the coil spring 70 is easily kept at a constant value through constitution having the reduced number of parts.
