Title: Low temperature vessel
Inventor: NAKAMURA KAZUAKI
IPC: F17C3/08
Filed: 1983-11-09
Abstract: PURPOSE:To prevent a freezing mixture from its evaporation even if the supply of cold gas to a heat-shield plate is stopped, by providing a plurality of heat- shield plate-heat exchangers in the heat-shield plate placed in vacuum heat-insulating layers and transferring the cold gas to be fed from the outside of a low temperature vessel to said heat exchangers. CONSTITUTION:A freezing mixture reservoir part 16, placed in the case of a low temperature vessel and maintained to a high vacuum by vacuum heat-insulating layers 15a, 15b, provides a heat-shield plate 2 so that heat from the case 1 may be not directly radiated into said layers. The heat-shield plate 2, even if a cold- cooling transfer circuit or a refrigerator for cooling said plate causes a trouble, can be cooled in every heat-shield plate-heat exchanger 3A, 4B, enabling evaporation of a freezing mixture to be prevented by opening cold gas injection valves 6, 8 and cold-cooling discharge valves 12, 14 so as to transfer cold-cooling to the heat-sheidl plate 2 from cold gas injection lines 5, 7 to be discharged from cold gas discharge lines 11, 13.

Title: Liquid sealed vibration proof bush
Inventor: MAENO TAKASHI
IPC: F16F13/14
Filed: 1990-08-08
Abstract: PURPOSE:To simplify a manufacturing process, and to reduce cost by forming an inner cylinder out of a metal cylinder and of a resinous layer solidly adhered to the outer periphery thereof, by protruding a part of the resinous layer so as to form an agitation plate, and by forming a whirl-stop of the inner cylinder 2 on the resinous layer at the time of molding a vibrationproof rubber. CONSTITUTION:An inter-ring 4 is fixed to the inner circumference of an outer cylinder 1, and a vibrationproof rubber 3 is linked with the upper half inner circumference thereof, while an inner cylinder 2 is buried in the center part of the bottom wall of the vibrationproof rubber 3. The inner cylinder 2 is composed of a metal cylinder 21 and of a resinous layer 22, a part of which is an agitation plate 23 protruded in a main liquid chamber A, while a whirl-stop part 24 is formed on the circumferential surface of both ends of the resinous layer 22. At the time of inputting large vibration, the volume of the main liquid chamber A is varied according to the upper and lower movement of the inner cylinder 2, and a sealed liquid is flown into a sub-liquid chamber B through an orifice channel 41, so as to generate periodic damping force. At the time of inputting fine vibration, the sealed liquid in the main liquid chamber A is resonated by the vibration of the agitation plate 23, and the vibration is absorbed thereby. Since the agitation plate 23 and the whirl-stop part 24 are integrated with the resinous layer 22, the assembly and process are simplified and the cost is reduced.

Title: Heat dissipation fin structure with built-in micro-heat-pipe
Inventor: YAMAGATA TOSHIO
IPC: H05K7/20
Filed: 1986-09-09
Abstract: PURPOSE:To achieve highly efficient heat dissipation by a method wherein a heat-pipe is composed of a part which is in contact with the upper surface of an electronic device and a part which penetrates the body of a heat dissipation fin main part is built in the heat dissipation fin main part which is composed of a plurality of plate- shape fin parts provided with certain intervals and the body which links the fin parts. CONSTITUTION:The lower part of a micro heat-pipe 20 is formed into a flat spiral 21 and warped upward from the center of the spiral. If the micro heat-pipe 20 is inserted into a heat dissipation fin main part 10, the lower spiral part 21 is fitted in the opening 14 of the heat dissipation fin main part 10 and the part 22 extended upward penetrates through the hole 15 of the body 13 of the heat dissipation fin main part 10. As the spiral part 21 is directly in contact with the upper surface of an electronic device 1, it receives the heat from the electronic device 1 and the liquid in the spiral part 21 is vaporized and quickly transferred to the upper part 22. As the upper part 22 is close to fin parts 11, the part 22 is always cooled and the vaporized liquid is condensed and transferred to the lower spiral part 21 through capillaries by gravity. By repeating this cycle, highly efficient heat dissipation can be achived in a short period.

Filed: 1985-09-24
Abstract: PURPOSE:To reduce the fluctuation in magnifying power due to temperature change by a method wherein the fluctuation of projection magnifying power due to the temperature change of a projection lens is nearly offset by the distance fluctuation due to temperature change in a reticle and a projection lens. CONSTITUTION:Multiple posts 4 are fixed between a base 5 and a column 2 to provide the distance (d) between an incident iris diaphragm (ep) of a projection lens 3 and the pattern surface of a reticle R with specific design value. Said posts 4 with pertinent thermal expansion coefficient subject to the expansion and contraction corresponding to temperature changes make the distance (d) fluctuate slightly. In such a constitution, an error in magnifying power DELTAM due to any temperature change can be self-corrected (offset) by means of specifying the material and dimension of posts 4 so that the reticle R may be displaced upward by DELTAd when the temperature change is +DELTAt from the reference specified temperature.

Title: Method for regulating fatigue strength of hot rolled high strength steel sheet
Inventor: KONO OSAMU
IPC: C22C38/00
Filed: 1995-07-28
Abstract: PROBLEM TO BE SOLVED: To secure desired fatigue strength in a steel sheet, at the time of subjecting a high strength steel sheet to hot rolling, by regulating the contents of Mn and Si in the compsn. of the steel sheet and the grain size of ferrite in the steel sheet structure. SOLUTION: At the time of subjecting a steel sheet to rolling at a temp. of the transformation point or above and thereafter allowing the same to undergo a cooling stage to form into a product, the contents of Si and/or Mn in the compsn. of the steel sheet and the grain size (d) of ferrite in the microstructure in the steel sheet are regulated so as to satisfy the formula to obtain fatigue strength 0.9 to 1.1 times the objective fatigue strength. Moreover, as for the cooling after the hot rolling, any of air cooling and water cooling may be executed.  Though secondary phase structures other than ferrite (pearlite, bainite, martensite, cementite, residual austenite and their tempered structures) also have influence on its fatigue strength, their influence is small as to the hot rolled steel sheet in the case of the one essentially consisting of ferrite (>=70% occupancy ratio), and it is ignorable.
