Publication number: 20200370200Abstract: Provided is a method of manufacturing an oriented steel plate having two or more regions in each of which a crystal orientation is arranged in a specific direction. In the method, at least two single crystal steels are brought into contact with a principal surface of a polycrystalline steel plate so that crystal orientations of the single crystal steels and are arranged in different directions, and heat treatment of the single crystal steels and the polycrystalline steel plate is performed. This causes crystal growth following the crystal orientations of the single crystal steels to occur in the polycrystalline steel plate. Then, two or more single crystal steels having different crystal orientations are formed in the polycrystalline steel plate.Type: ApplicationFiled: May 22, 2020Publication date: November 26, 2020Inventors: Hiroki TAKAHASHI, Satoshi DOI, Keiichi OKAZAKI, Hidemasa OTSUBO, Yutaro SUGIMOTO, Jun YANAGIMOTO

Patent number: 6252482Abstract: A high voltage post terminal is accurately located within a support aperture during manufacturing processes by at least one inwardly directed projection to avoid assembly problems caused by sizing the entire aperture itself to locate the terminal with sufficient accuracy. By thus improving the concentricity of the high voltage coil components it is possible to achieve more reliable insulation between components at even relatively small-sized coils used for individual engine plug holes. An especially advantageous range of critical parameters has been discovered as achievable by using this more reliable manufacturing process.Type: GrantFiled: December 10, 1998Date of Patent: June 26, 2001Assignee: Denso CorporationInventors: Tomonari Chiba, Kazutoyo Oosuka, Keiichi Okazaki, Hiromitsu Oonishi, Masahiko Aoyama
