Title: Manufacture of roll having excellent surface stability
Inventor: NOMICHI SUEYOSHI
IPC: C21D8/00
Filed: 1984-06-13
Abstract: PURPOSE:To obtain a roll having uniform and minute structure and excellent surface stability by applying cold plastic working to a roll barrel material which is cast from an austenitic alloy, and then subjecting the material to recrystallization heat treatment. CONSTITUTION:A columnar roll barrel material is cast from an austenitic alloy by centrifugal casting, etc. The material is subjected to cold plastic working at >=10% draft, and then to recrystallization heat treatment at about 900 deg.C. Then solid soln. treatment is applied in accordance with the requirement at about 1,000-1,250 deg.C. Since the roll barrel part obtained by said method has uniform and fine crystal structure and hence excellent surface structure, the initial smooth surface is kept without generating ruggedness even when used under conditions where thermal stress is generated. Accordingly, the roll is applicable to a bending roll for manufacturing sheet glass, etc.

Title: Lockup controller for automatic transmission
Inventor: SHIMIZU HIROFUMI
IPC: F16H61/14
Filed: 1996-04-22
Abstract: PROBLEM TO BE SOLVED: To relieve gear shift shock caused by gear shift by conducting real time feedback control based on various variables changing with respective gear shift conditions even if gear shift occurs during lockup control. SOLUTION: After a gear shift command detection means 202 detects gear shift start, gear shift inertia phase start is discriminated during lockup control by an inertia phase detection means 204. In the case of driving with an inertia phase, real time feedback control is conducted for optimum lockup engagement pressure corresponding to respective gear shift conditions by a slip control pressure change means 206 so that a difference between actual engine speed obtained by an engine speed detection means 210 and target engine speed calculated by an engine speed detection means 210 may be zero. It is thus possible to set the fastening face of a lockup clutch 31 to a prescribed range at the time of gear shift completion for relief of gear shift shock even if the various variables of an automatic transmission 15 change at the time of respective gear shift.

Title: Ice making pan
Inventor: OBATA SHINGO
IPC: F25C1/24
Filed: 1996-05-17
Abstract: PROBLEM TO BE SOLVED: To enable a thermal conduction to be increased and ice to be manufactured within a short period of time by a method wherein an ice making pan is formed by a polypropylene resin added with a high thermal conductive substance. SOLUTION: This ice making pan is produced by making a resin mixed with a high thermal conductive substance 8 and polypropylene resin 6 and injecting the mixed resin through a molding machine. As regards a thermal conductivity of the ice making pan, the more an adding amount of the high thermal conductive substance 8, the higher the thermal conductivity and them an ice making time is shortened. In addition, since a contact probability between the high thermal conductive substance 8 becomes high if a phase of the additive agent is in a fibrous form rather than a particle shape and its fiber length is longer, its thermal conductivity is increased and the ice making time can be shortened. Further, when the high thermal conductive substance 8 is of solid carbon, the ice making time can be shortened.  Since a specific weight of the solid carbon is low, a proper characteristic of polypropylene resin such as light weight and superior molding characteristics can be maintained, its mechanical strengths such as the flexural modulus and impact strength or the like can be improved.
