Title: Circulation pipe for heat storage system
Inventor: OKUMURA MASAHIKO
IPC: F28F19/04
Filed: 1997-07-01
Abstract: PROBLEM TO BE SOLVED: To achieve the stability of ice making rate by applying polyethylene or crosslinked polyethylene on the internal and external surfaces of an aluminum pipe to form a composite pipe with a specified thickness, which prevents a drop in heat conductivity caused by corrosion of the internal surface of a circulation pipe. SOLUTION: A polyethylene layer or crosslinked polyethylene layers 22 and 23 are applied on the internal and external surfaces of an aluminum pipe 21 to form a composite pipe with a thickness of 1.0-3.0 mm. A circulation pipe thus formed is arranged in a closed water tank in a multi-stage zigzag fashion or in a coil-like pattern. In this manner, since the composite pipe which has the chemically stable polyethylene or cosslinked polyethylene applied on the internal surface of the circulation pipe is used, even when a large amount of moisture is contained in a circulation oil mixed refrigerant, the internal surface of the circulation pipe can be kept stable to be protected from the corrosion. The simultaneous application of the same coating is made on the external surface of the circulation pipe thereby allowing the elimination of the corrosion of the external surface.

Title: Manufacture of semiconductor device
Inventor: MIENO FUMITAKE
IPC: C08G77/12
Filed: 1992-07-03
Abstract: PURPOSE:To provide a method for forming an insulator film of fine film quality not only on a silicon but also on an insulator by adopting a CVD method which uses TEOS and O3. CONSTITUTION:Polysilane with hydrophilic functional group at an end is brought into contact with a substrate whereon silicon and an insulator (SiO2 PSG, BPSG, Si3N4, etc.) are mixed by adopting Langmuir-Blodgett's technique. A thin film of polysilane is formed by combining hydrophilic functional group of polysilane with a surface of a substrate. After the hydrophilic functional group of polysilane is decomposed and removed by performing thermal treatment or optical irradiation for a substrate whereon a thin film of polysilane is formed, a flat insulator film is formed on a substrate by adopting a CVD method which uses mixture gas of TEOS and O3.

Title: Drain-drying method
Inventor: NAKAGAWA TETSUO
IPC: B01D12/00
Filed: 1990-07-03
Abstract: PURPOSE:To eliminate the generation of a stain and to reduce the number of the remaining foreign matters on the surface of a substrate of a substrate by a method wherein the substrate is immersed in a specific solvent and subsequently drawn up to be drained, or the level of the solvent is lowered to drain the substrate and, thereafter, the substrate is dried by the remaining heat thereof or heating. CONSTITUTION:A washed substrate is immersed in a solvent freely mixing with water and drawn up to be drained or the level of the solvent is lowered to drain the substrate and the substrate is further dried by the remaining heat thereof or heating. As the solvent freely mixing with water, alcohols, ketones, cellosolves and mixtures thereof are used. Since the solvent is low in surface tension and has high water solubility, even the water in the fine recessed parts of the substrate having a complicated surface shape is dissolved to be removed from the substrate. Next, the substrate is drawn up or the level of the solvent is lowered and, at this time, the film of the solvent remains on the substrate but the thickness thereof is suppressed to a low level because of the low surface tension of the solvent.

Title: Treatment of exhaust gas
Inventor: ITO YOSHIRO
IPC: B01D53/81
Filed: 1992-06-11
Abstract: PURPOSE:To efficiently remove a harmful substance from exhaust gas by making the caliber of the aperture parts of the air permeable structure on the side of an exhaust gas inlet larger than the diameter of a granular substance. CONSTITUTION:The walls on the inlet and outlet sides of exhaust gas are respectively constituted of air permeable structures 2, 3 and the caliber of the aperture parts of the air permeable structure 2 is made larger than the diameter of a granular substance 12. Whereupon, a part of the granular substance 12 flowing down in the vicinity of the air permeable structure 2 on the inlet side of exhaust gas passes through the aperture parts to fall in an exhaust gas introducing part 7 to be accumulated on the lower part of the exhaust gas introducing part 7 and passes through the return passage 10 of the granular substance 12 to meet with the granular substance flowing down through a moving bed in a discharge part. By this constitution, the accumulation of dust or a reaction product on the air permeable structures or the granular substance in the vicinity thereof can be prevented. Therefore, an apparatus can smoothly be operated without generating a rise in pressure loss or the offset flow of gas.

Abstract: PROBLEM TO BE SOLVED: To effectively reduce vibration caused by reciprocating motion of a slider by providing a reciprocating mechanism capable of reciprocating a counterweight in the inverse direction via an annular body according to the reciprocating motion of the slider.

Abstract: PURPOSE:To set up a beam crossing angle on a reading window to a prescribed angle or more and to reduce the width of the reading window by forming penetration parts on facets of a hologram disk and making a penetrated laser beam incident again from another position of the same facet through optical means. CONSTITUTION:While rotating the hologram disk 22, a laser beam (a) reflected by a mirror 12 is vertically irradiated from a fixed position upon the surface of the hologram disk. When the laser beam (a) is made incident upon a facet A, the beam (a) is diffracted by the hologram as shown in a solid line, reflected by mirrors 8, 9 and emitted from the reading window 11 as a laser beam (b). On the other hand, the laser beam (a) made incident upon a facet B is straight passed through the penetration part 28 as it is and then vertically irradiated from an upper part to another position of the same facet B through mirrors 23-25. Thereby, the emitting points of two laser beams (b), (c) emitted from the hologram disk 22 are different positions on the reading window 11 though the incident point of the laser beam (a) emitted from an unshown laser beam source to the hologram disk 22 is a single point.
