Publication number: 20060091736Abstract: The conventional linear drive apparatus has the problem that in constructing a linear motor of a multiphase structure by connecting a plurality of armature units, the length of the armature becomes longer in proportion to the number of the phases, thus limiting the locations where the apparatus can be installed. The problem is solved by a linear drive apparatus comprising a plurality of armature units 3 formed by a magnetic material on which a conductor coil 4 is disposed, and an armature comprising an arrangement of the armature units 3. The armature units 3 comprise a plurality of opposing portions having opposing magnetic pole teeth. The magnetic pole teeth of adjacent opposing portions are arranged in an interdigitated manner. A secondary member 6 is disposed between magnetic pole teeth of the opposing portions. The armature units 3 comprise the coil 4 arranged on opposite sides thereof in an alternating manner.Type: ApplicationFiled: December 12, 2005Publication date: May 4, 2006Inventors: Houng Kim, Kohji Maki, Misao Tadokoro, Hideki Shimane, Hitoshi Shibata, Keijiro Sakai

Publication number: 20040069873Abstract: A nozzle holder includes a support portion, which supports a downstream end surface of a planar wall of an injection hole plate. The injection hole plate provided with injection holes is welded to one of the valve body and the nozzle holder. The planar wall may be curved and may be thus convex in an upstream direction toward a downstream end opening such that the planar wall is urged against a peripheral edge of the downstream end opening of the valve body. The planar wall may include a reinforcing rib located radially outward of the injection hole.Type: ApplicationFiled: July 16, 2003Publication date: April 15, 2004Inventors: Yasuhide Tani, Kimitaka Saito, Nobuo Ota, Yoshitaka Wakamatsu, Hitoshi Shibata, Masaaki Konishi

Patent number: 4841155Abstract: Disclosed is an indication device of a gauging apparatus comprising an indicator panel having, on its surface, indication marks including patterns and characters, and a black light source for illuminating the surface of said indicator panel to excite a phosphor. Background portions of the indicator panel other than the indication marks are printed with a phosphor-containing paint which differs in color when it is exposed to light from the black light source from when it is exposed to ordinary light unable to excite the phosphor. The indication marks are printed with a white color paint which does not contain a phosphor and the phosphor-containing paint assumes a dark color when it is exposed to the ordinary light and assumes a bright color when it is exposed to light from the black light source.Type: GrantFiled: May 28, 1987Date of Patent: June 20, 1989Assignee: Nippondenso Co., Ltd.Inventors: Masahiko Ushida, Hitoshi Shibata
