Title: Molding of cover integrated foam molded object
Inventor: MIYAGUCHI MASATO
IPC: B29C39/10
Filed: 1995-01-18
Abstract: PURPOSE: To certainly mold a cover integrated foam molded object having a regular shape by sufficiently expanding a cover. CONSTITUTION: A molding wire 30 made of a shape memory alloy is attached to the interior of the cover 10 housed in a mold 50 along the seam 18 thereof. When a foamable filler 20 is injected into the cover 10, the molding wire 30 heated by the heat of the foaming reaction of the filler is deformed to be restored to a memory shape and the cover 10 is expanded into a predetermined shape by the restoration force of the wire to come into close contact with the inner wall of the mold 50. Since the molding of the cover is performed by the shape restoration force of the shape memory alloy stronger than the foaming expansion force of the foamable filler 20, the cover 10 can be certainly expanded into a regular shape.

Title: Production of two-phase stainless steel
Inventor: SAKASHITA MOTOKI
IPC: C22C38/00
Filed: 1988-02-03
Abstract: PURPOSE:To improve the corrosion resistance, strength, toughness, corrosion fatigue strength, etc., of the title steel having specified composition and structure by holding the steel at a specified solid soln. temp. for specified hours, and then cooling the steel by forced air. CONSTITUTION:The casting of the title steel consisting of <=0.03% C, <=1% Si, <=2% Mn, 23-25% Cr, 3.5-5.5% Ni, 2-4% Mo, 0.5-1.5% Co, <=1% Cu, 0.15-0.25% N, and the balance Fe and wherein the ferrite amt. in the two-phase structure of austenite and ferrite is controlled to 50-70% in terms of an area ratio is prepared. The casting is held at a solid soln. temp. of 1000-1150 deg.C for 0.5-2hr per inch thickness, and then cooled by forced air. When the solid soln. temp. is lower than that above mentioned or the holding time is shorter, the solid soln. rate of the alloy elements and the homogenizing of the structure are insufficient. Meanwhile, when the temp. is higher and the time is longer, a state of sensitization is caused, and the corrosion resistance is deteriorated. Since the cooling is carried out by forced air, residual stress is reduced, and a specified soln. heat treatment effect can be secured.

Title: Method and device for cold molding iron and non-ferrous metal by roller bending
Inventor: BUARUTAA SHIYUPEETO
IPC: B21D11/06
Filed: 1990-02-03
Abstract: PURPOSE: To conduct cold forming without damaging an outer shell and changing in a cross section by freely setting a coiling form position adjustable on the same line as a bending line of a bending head without providing intervals in all three directions and complementarily remote controlling the coiling form freely rotatably. CONSTITUTION: A forming object 17 (coiling wire) is bent in spatial axes (X, Y, Z) in three directions by a tool. The forming object 17 to be bent to a spherical shape is freely bent in a space by a bending head 52 without a die frame for bending or a boring bar support. Thus a coiling form 48 is freely set with its position adjustable on the same line as a bending line of a bending head 52 without providing intervals in all three directions. In addition, remote control for freely rotating is conducted. By this method, the forming object is free from collapsing in a bending process and deforming a cross section.

IPC: B62D3/12
Filed: 1997-02-07
Abstract: PROBLEM TO BE SOLVED: To surely restrain the occurrence of gear meshing sound in the whole region of gaps indispensable for assembly while excellent steering feeling is being kept. SOLUTION: A spring frictional body 34 is held between a rack guide 24 and a cap 26. The spring frictional body 34 is equipped with a disc spring part 36 functioning as a spring element, and with a leg part 38 functioning as a frictional element. Frictional force as specified is produced by letting the leg part 38 intended to be displaced to the outer side in the radial direction be pressed into contact with the outer side wall surface 40A of an annular recessed part 40. Yet, in this case, no constituent in the axial direction is produced, by which the disc spring part 36 is affected. Therefore, the occurrence of gear meshing sound can surely be prevented in the whole region of gaps necessary and indispensable for assembly while excellent steering feeling is being kept.

Title: Semiconductor element
Inventor: SUGIMOTO HIROYUKI
IPC: H01L27/12
Filed: 1989-02-06
Abstract: PURPOSE:To prevent a heat-dissipating property from being lowered while an SOI(silicon on insulator) structure is being held by a method wherein a diamond which is insulating and whose heat-conducting property is good is used instead of SiO2 as an insulator layer. CONSTITUTION:A diamond is used as an insulator layer 2 instead of SiO2; the insulating layer 2 is formed on a silicon substrate 1; a silicon layer 3 having an electronic circuit is pasted on it. A thermal conductivity of the SiO2 is 0.1J/ cmKs and that of the diamond is 23J/cmKs; that of the diamond is large by 200 times or higher; this directly contributes toward a heat-dissipating property of an element. In addition, this effect becomes much more large when a metal such as nickel or the like is used as the substrate on which the diamond is grown. Thereby, it is possible to obtain a semiconductor element of an SOI structure whose heat-dissipating property is good.
