Filed: 1957-01-09
Abstract: 825,662. Nuclear reactors. A. E. I.-J. THOMPSON NUCLEAR ENERGY CO. Ltd. Jan. 1, 1958 [Jan. 9, 1957]. No. 872/57. Drawings to Specification. Class 39(4). In a gas cooled nuclear reactor the fuel ducts are sealed at the upper ends by a removable closure and a valve, to permit the access of a fuel charging apparatus to the duct. Normally, with the closure removed, there is a pressure drop across the valve, owing to the difference between the duct gas and the atmospheric pressures. The pressure difference operates a catch mechanism to prevent opening of the valve. However upon connecting to the upper end of the duct, a charging apparatus which has a pressurized gas supply associated with it, the catch is released and the valve is operable. The cooling gas and the valve servo fluid are both carbon-dioxide with leakage from the servosystem to the reactor does not latex contamination of the coolant. The servo-system discharges into the cooling system.

Abstract: PROBLEM TO BE SOLVED: To reduce the dispersion of resonance frequencies to avoid resonance with outside vibration and make production easy by pressing a frame part from the inside to the outside, and pressing the vicinity of the joining point of the frame part from the inside to the outside to deform the whole frame. SOLUTION: An elastic bottom supporting part 7 of a frame 3 is depressed from the inside to the outside, and the vicinity of the joining point of a metal thin plate holding frame part 6 is depressed from the outside to the inside. As the depressing point of the elastic bottom supporting frame part 7, a plurality of depressing points may be set in addition to the central point of the elastic bottom supporting frame part 7 for more uniform deformation. The metal thin plate holding frame part 6 is uniformly deformed, tension applied to an electrode is made almost uniform, and the dispersion of resonance frequency is reduced. Since the elastic bottom supporting frame part 7 is depressed from the inside, the interference of a fixing device for fixing the electrode with a pressing device for applying the depressing force is not produced, and the production is made relatively easy.

Title: Manufacture of semiconductor integrated circuit
Inventor: OOTSUKI HIROAKI
IPC: H01L21/324
Filed: 1983-01-07
Abstract: PURPOSE:To enable to simply control the resistance value of a polycrystalline silicon film in the final step by performing the annealing at relatively low temperature lower than the melting point of aluminum as a metal wiring material in hydrogen gas atmosphere or nitrogen gas atmosphere. CONSTITUTION:When hydrogen atoms are introduced into polycrystalline silicon to be coupled to unpaired electrons, the energy barrier of polycrystalline grain boundary becomes small so that free carrier density substantially increases with the result that the resistance value of the polycrystalline silicon decreases. On the contrary, when the hydrogen atoms which are once introduced are dissociatand released by applying energy from the exterior thereto, the resistance value again increases. The introduction or release of the hydrogen atoms can be readily performed by annealing in the hydrogen gas atmosphere or nitrogen gas atmosphere of relatively low temperature (e.g., 500 deg.C) lower than the melting point of aluminum as general wiring material.

Title: Apparatus for heat-treating macromolecular material
Inventor: ISHIHARA HIDEAKI
IPC: B29C35/10
Filed: 1984-01-06
Abstract: PURPOSE:To make uniform temperature heating possible so as to provide stable quality, by applying to a macromolecular material an adhesive agent whose boiling point is up to the melting point of the macromolecular material and whose boiling point is near the heat-treating operation temperature, and heating the adhesive agent to evaporate. CONSTITUTION:A mocromolecular material 2 is dipped in a dipping tank 6 containing an adhesive agent 7 so that the material 2 is impregnated with the adhesive agent 7. The macromolecular material 2 impregnated with the adhesive agent 7 is subjected to microwave dielectric heating by a heating apparatus 10, and when the temperature level reaches the level of the boiling point of the adhesive agent 7, the adhesive agent 7 evaporates. Thus the macromolecular material 2 is deprived of the heat due to the heat of evaporation, and therefore the temperature thereof would not increase. Accordingly, by setting the moving speed of the macromolecular material 2 suitably, uniform temperature heating of the macromolecular material 2 can be easily attained, so that abnormal rising of temperature of scattering of temperature can be prevented.
