Patent number: 7682667Abstract: An adhesion strength of spray coating comparable to that obtained in a conventional combination of blast treatment and gas flame spraying can be realized even if roughening is conducted with the use of simple tools by performing in advance such a roughening treatment that the average roughness (Ra) of the surface of the thermal spray subject falls within the range of 2 to 10 ?m with the use of a grinding tool, and thereafter carrying out thermal spraying under such conditions that the average area of each of molten particles when molten particles of a thermal spray material have stuck to the surface of thermal spray subject falls within the range of 10000 to 100000 ?m2. In the roughening by grinding tools, a large-scale apparatus is not needed as different from the blast treatment, and portable small tools can be used in overhead location work at field repair. The scattering of powder resulting from grinding is slight so that the danger of environmental pollution is low.Type: GrantFiled: October 15, 2004Date of Patent: March 23, 2010Assignees: Nishinippon Plant Engineering and Construction Co., Ltd., Yamada Corrosion Protection Co., Ltd., Kyushu Electric Power Co., Inc.Inventors: Yukio Imaizumi, Hiroki Kamakura, Toshio Sakurada, Kenichi Yamada, Katsuhiko Ishibashi

Publication number: 20090031978Abstract: A heat accumulator (1) is formed by connecting a first container (4) and a second container (5) using a spring (6). The first container (4) has a wall-shaped inner side wall that corresponds to the shape of a cylinder bore wall (7). Provided on this inner side wall is a flexible structural part (8). The flexible structural part (8) is formed of highly elastic resin. The second container (5) has a similar structure. A heat storage medium within the first container (4) and the second container (5) absorbs heat, which generates a change of phase from a solid to a liquid. When this happens, the volume of the heat storage medium increases. The increase in the heat storage medium projects the flexible structural part (8), and separates the first container (4) and the second container (5) from the cylinder bore wall (7).Type: ApplicationFiled: February 8, 2007Publication date: February 5, 2009Applicant: TOYOTA JIDODHA KABUSHIKI KAISHAInventors: Hideo Kobayashi, Katuhiko Arisawa, Kenichi Yamada, Yoshio Yamashita, Kunihiko Hayashi
