Publication number: 20040209099Abstract: A flexible natural wood sheet excellent in softness and folding endurance, which is obtained by overcoming a disadvantage of a thin natural wood plate material that it is easily cracked or broken, without loosing texture and feeling inherent to natural wood, is provided. Cavities in the thin natural wood plate material are filled with a polymer compound to impart softness and folding endurance to the thin natural wood plate material. At the same time, the surface of the thin natural wood plate material is not entirely covered by filling the polymer compound. Accordingly, the problem can be solved.Type: ApplicationFiled: December 23, 2003Publication date: October 21, 2004Inventors: Manshi Ohyanagi, Shin'ichi Higuchi, Takeshi Yamamoto

Publication number: 20040126306Abstract: A process for producing graphite grains, characterized by graphitizing carbon black by induction heating. A process in which at least one element selected from metals, boron and silicon is contained in graphite grains is preferable. Refractories obtained by molding a composition containing a refractory filler and the graphite grains produced by the foregoing process are excellent in thermal shock resistance, oxidation resistance and corrosion resistance. Consequently, a process for producing graphite grains in which the graphitization of carbon black that requires quite a high temperature in an ordinary heating method can easily proceed is provided. Further, refractories excellent in thermal shock resistance, oxidation resistance and corrosion resistance and having a low carbon content are provided.Type: ApplicationFiled: February 11, 2004Publication date: July 1, 2004Inventors: Tsunemi Ochiai, Shigeyuki Takanaga, Manshi Ohyanagi

Patent number: 6432150Abstract: A superabrasive containing layered composite is provided which comprises a substrate block consisting of either ceramic material and metallic or several metallic materials, and a superabrasive containing body adjacent said substrate block. The superabrasive contains superabrasive particles, and a metallic ingredient which is distributed in the superabrasive containing layer, including a working surface. The superabrasive material may be formed using a compression cell wherein the compression cell comprises a die defined by a vertical wall and a flat closed bottom. Placed in the die, in order from bottom upward, comprises a formed pallet of single body or layers of mixed powder forming a refractory compound, a material mass of a working layer containing diamond particles, a mass of ignition material comprising an SHS composition, and an electrical heating element.Type: GrantFiled: May 12, 2000Date of Patent: August 13, 2002Assignees: The Ishizuka Research Institute, Ltd., Moscow Steel and Alloys Institute, SHS-CenterInventors: Evgeny Alexandrovich Levashov, Alexander Sergeevich Rogatchov, Boris Vladmirovich Spitsin, Mitsue Koizumi, Manshi Ohyanagi, Satoru Hosomi
