Title: Heat treating method for austenitic stainless steel of high resistance against stress corrosion cracking
Inventor: KIRIHARA SEISHIN
IPC: C21D6/00
Filed: 1978-06-21
Abstract: PURPOSE:To prevent the generation of stress corrosion cracjing, by cooling the austenitic stainless steel including the sensitized zone due to the heat affection of the welding, etc., to under the Ms point for forming the martensite structure. CONSTITUTION:In the grain boundary of the austenitic stainless steel and the heat affected zone of the welded joint of the same steel, the chronium carbide precipitates forming the so-called sensitized zone, which causes the stress corrosion cracking when it is exposed to the corrosive environment. In this case, the material is cooled using the liquiefied nitrogen, liquiefied oxygen, liquiefied air, etc., down to the martensite transformation beginning point (Ms point ); hereby, the cooled part is transformed into the martensite structure. Hereby, the low chromium part due to the precipitation of the chromium carbide causes the martensite transformation and improves its strength; and besides, depending on the expansion due to the martensite transformation, the residual stress is locally changed from the tensile stress to the compression stress, so that the generation of the stress corrosion cracking is further reduced.

Title: Multi-stage pulley and its manufacture
Inventor: MASAHARA HIROSHI
IPC: F16H55/42
Filed: 1998-03-23
Abstract: PROBLEM TO BE SOLVED: To reduce the manufacturing costs of a multi-stage pulley by preventing damage of a groove-equipped roller. SOLUTION: A ring-shaped groove 104 is formed between groove parts 101, and groove parts 101 are formed in the condition that the ring-shaped groove 104 is pressed. Thereby a stress generated in association with plastic deformation when the groove parts 101 are formed can be released to the ring-shaped groove 104 having a smaller rigidity than the groove parts 101, so that unnecessary plastic deformation of the groove parts 101 can be precluded to lead to enhancement of the dimensional accuracy in furnishing a multi-stage pulley. Further the investment in the equipment for groove-equipped rollers 204 and 207 can accordingly be suppressed, which should reduce the manufacturing costs of the multi-stage pulley.

IPC: B29C55/12
Filed: 1998-03-24
Abstract: PROBLEM TO BE SOLVED: To provide excellent scratch resistance by forming a film so that the elastic deformation quantity in the total deformation quantity at a time when push-in deformation is applied to a surface becomes a specific ratio. SOLUTION: Polyethylene-2,6-naphthalate is dried under vacuum to be extruded from a T-die in a molten state. This extrudate is closely bonded to a cooling drum while static electricity is applied to the drum to be cooled and solidified to obtain an unstretched web. Thereafter, steam spraying treatment is applied to both surfaces of the web and, succeedingly, this unstretched web is stretched by 3.3 times in its longitudinal direction by a roll type longitudinal stretching machine. Further, this web is stretched by a tenter type lateral stretching machine so that lateral stretching magnification is 3.3 times. Subsequently, the web is heat-treated and further thermally fixed in a thermal fixing zone. The web is gradually cooled while slackened by 5% laterally to be taken up to obtain a film with a thickness of 85 μm. This film is further heat-treated at 110 deg.C for 48 hr.  In this film, the ratio of the elastic deformation quantity of the total deformation quantity at a time when push-in deformation is applied, to the surface of the film is 60% or more, that is, 64%.
