Patent number: 5571612Abstract: An anisotropic nanophase composite material and a method of producing same. The composite material comprises a nanophase composite structure containing a multiplicity of particulates of at least one material. The particulates of one material are spaced from each other three-dimensionally and anisotropically oriented in a given direction. The particulates have an average thickness of 1 to 10 nanometers and an average length of not less than 10 nanometers, the length being larger than the thickness. Since the particulates of dimensions on the order of nanometers are oriented only in a given direction, the composite material produces an intensified nonlinear optical effect and is excellent in polarizing characteristics, birefringent characteristics, or photovoltaic characteristics.Type: GrantFiled: December 20, 1994Date of Patent: November 5, 1996Assignee: Kabushiki Kaisha Toyota Chuo KenkyushoInventors: Tomoyoshi Motohiro, Yasuhiko Takeda, Shoji Noda, Yoshihide Watanabe

Patent number: 5120971Abstract: The invention relates to a method and a device for reflection-type pattern copying, characterized by letting beams of light be incident on a pattern reflection plate on which a pattern to be copied is drawn, converging a pattern figure contained in the light reflected by the pattern reflection plate by means of a concave mirror and copying a two-dimensionally reduced pattern of the above pattern onto a surface of a specimen. Unlike conventional methods, the invention achieves two-dimensional reduced pattern copying by using one concave convergence mirror. A region of copying in which the blur size is not larger than a certain sufficiently small value can be expanded by parallelly arrnaging many concave convergence mirrors having the same shape and combining mechanical sweeping of the pattern reflection plate and the specimen.Type: GrantFiled: December 26, 1990Date of Patent: June 9, 1992Assignee: Hiroshima UniversityInventors: Hideki Matsumura, Yoshihide Watanabe

Patent number: 5112790Abstract: A catalyst used for purifying exhaust gases resulting from the combustion of a lean fuel-air mixture mixture comprises a porous support material having a framework formed by MO.sub.2, where M is silicon or a metal, AlO.sub.2 and PO.sub.2, and at least one base metal and at least one metal of the platinum group which are carried on ion exchange sites of the support material a coexistent state. The catalyst exhibits a high level of NO.sub.x conversion for a long time even at a high temperature owing to the high heat resistance and durability of the support material, and the cooperative action of the two kinds of metals, i.e. the promotion of the catalytic action of the base metal (e.g. copper) by the metal of the platinum group (e.g. palladium) serving as cocatalyst.Type: GrantFiled: April 27, 1990Date of Patent: May 12, 1992Assignees: Kabushiki Kaisha Toyota Chuo Kenkyusho, Toyota Jidosha Kabushiki KaishaInventors: Yoshihide Watanabe, Mareo Kimura, Shinichi Matsumoto
