Title: Carbon fiber reinforced carbon composite material crucible for pulling up semiconductor single crystal
Inventor: YAMAJI MASATOSHI
IPC: H01L21/208
Filed: 1996-08-20
Abstract: PROBLEM TO BE SOLVED: To obtain a crucible having excellent resistance to reaction with Si by forming a pyrolytic carbon protective coating film on a semiconductor pulling-up crucible totally or partly consisting of a carbon fiber reinforced carbon composite material (C/C material). SOLUTION: In the manufacture of this crucible, the production of a C/C material used comprises e.g.: impregnating a 3-D (three-dimensionally structured) fibrous material consisting of carbon fiber with a resin; subjecting the impregnated fibrous material to heating and hardening to form a formed body; carbonizing the formed body in a non-oxidizing atmosphere to form a carbonized C/C material; then, successively subjecting the carbonized C/C material to re-impregnation, carbonization and heat treatment at a high temp. to convert it into a graphitized C/C material. At this time, in order to inhibit the conversion of a part of the graphitized C/C material thus produced into SiC by reaction with SiO2 in the surface of the graphitized C/C material, a pyrolytic carbon coating film is formed over minute open pores in the surface of the graphitized C/C material.  This film is a high purity pyrolytic carbon coating film and formed by subjecting a gaseous hydrocarbon having three carbon atoms to pyrolysis to form pyrolytic carbon and depositing the resulting pyrolytic carbon on a deep layer inside the graphitized C/C base material and preferably has a <=20μm film thickness. In the figure showing examples of such crucibles, a crucible (a) has a pyrolytic carbon coating film 3 formed over the open pores of a main body 2 and a crucible (b) has a side cylinder part 2a which consists of a graphitized C/C material and only on the inner surface side of which a pyrolytic carbon coating film 3 is formed.

Title: Decorative panel for space heating
Inventor: MASUGUCHI YOSHITSUGU
IPC: B27K5/06
Filed: 1986-10-06
Abstract: PURPOSE:To enhance the dimensional stability retaining the characteristics of wood, prevent odor from being generated at the time of space heating and reduce the cost by a simplified manufacture of a space heating decorative panel having a lamination of a porous panel and a wooden panel on one side of a heat generating body by impregnating the wooden panel with synthetic resin liquid, which is dried and solidified. CONSTITUTION:Synthetic resin is dissolved in a solvent, and is impregnated to a wooden panel 4 under either a decompressioned condition or normal condition. It solidifies in the wooden panel 4 by vaporizing the solvent by drying. When a polymer having a hydrophilic radical is used as a synthetic resin, its film covers the surface of cell membrane without entering inside the cell of wood, and so, the dimensional stability of the wooden panel 4 is enhanced and its moisture absorbing property is reduced. On the top of a planar heat generating body 1 which utilizes an electric heater or hot water as its heat source, a porous panel 3 and the wooden panel 4 are laminated and bonded in this order with a heat diffusing sheet underneath. The heat diffusing sheet 2 is made of either thermally conductive metallic sheet, plastic sheet, paper or fabric etc., or a lamination of two or more kinds of them. It helps to uniformly distribute the heat transmitted from the heat generating body 1, and, at the same time, reinforces or insulates the heat generating body 1.

Title: Fuel injection valve
Inventor: YAMAMOTO YASUHIRO
IPC: F02M51/06
Filed: 1992-09-08
Abstract: PURPOSE:To keep off the worsening of accuracy in an injection quantity by delaying the valve opening velocity of a needle valve in time of fuel injection. CONSTITUTION:When a piezoelectric element 8 is contracted and a volume in a back pressure chamber 20 is increased as well as when volumetric capacity increases and the piezoelectric element 8 extends but the volume of the back pressure chamber 20 is decreased, there is formed a pressure control chamber 24 where the volume is reduced. In addition, the pressure control chamber 24 and the back pressure chamber 20 are interconnected by a throttle passage 25. When the volume of the back pressure chamber 20 is increased and a needle valve 4 gets going up by means of a valve opening signal, fuel pressure in the back pressure chamber 20 goes up. At this time the volume of the pressure control chamber 24 grows larger and the fuel pressure in this chamber 24 is being lowered. In consequence, there is produced a difference between the fuel pressure in the chamber 20 and that in the control chamber 24, therefore fuel in the back pressure chamber 20 is gradually flowing out via the throttle passage 24. Since the needle valve 4 goes up with this fuel outflow, an up velocity in the needle valve 4 is lowered.

Title: Godet roller
Inventor: OGATA KENJI
IPC: C23C24/10
Filed: 1986-10-08
Abstract: PURPOSE:To improve the abrasion resistance by forming a padding layer through the powder padding welding at the contact part with the fiber of a godet roller and carrying out the surface hardening through the vapor deposition method. CONSTITUTION:The basic material 3 of a godet roller is made of the austenite group hot working tool steel, and a prescribed heat treatment is applied. The abrasion-resistive alloy is padding-welded onto the outer periphery of the basic material 3 through the powder padding-welding, and a padding layer 4 is formed. Since the padding layer 4 is fixed with the basic material 3 with a strong bonding force through a diffusion layer, generation of exfoliation is prevented. Further, since the padding layer 4 is formed by the melting of the powder whose constituent and content can be arbitrarily selected, the abrasion resistance can be improved. Further, a hardened layer 5 whose surface layer is hardened by the vapor deposition method is formed onto the padding layer 4. Therefore, the abrasion resistance can be improved markedly, and the long service life of the roller can be achieved, and cost cut is permitted.
