Publication number: 20240182742Abstract: A covering composition in which a heat-resistant resin (A), a non melt-processible fluorine-containing polymer (B) and a melt-processible fluorine-containing polymer (C) are dispersed in a water medium. The particulate resins (A) to (C) have an average particle size of 0.1 to 10 ?m, and the covering composition is substantially free from methylcellulose. Also disclosed is a covered article including a substrate; a primer layer formed by directly applying the covering composition to the substrate; and a topcoat layer containing a fluorine-containing polymer.Type: ApplicationFiled: January 30, 2024Publication date: June 6, 2024Applicant: DAIKIN INDUSTRIES, LTD.Inventors: Seitaro YAMAGUCHI, Yukari Honda, Yasukazu Nakatani

Patent number: 11183852Abstract: A control unit repeats the series of processing of comparing a first phase representing a phase of the first reference sine wave and being a phase included in the first synchronization signal, with a second phase that is the phase of the second reference sine wave when the first synchronization signal is received when the communication unit receives the first synchronization signal from the other inverter generator, changing a phase change amount per unit time of the second reference sine wave in accordance with the comparison result, continuing to update the phase of the second reference sine wave so that the phase of the second reference sine wave changes with a phase change amount per unit time after the change with reference to the first phase until the next first synchronizing signal is received from the other inverter generator.Type: GrantFiled: December 12, 2017Date of Patent: November 23, 2021Assignee: SHINDENGEN ELECTRIC MANUFACTURING CO., LTD.Inventors: Kazuo Yamashita, Yasukazu Yamaguchi

Patent number: 8573908Abstract: A machining center wherein improved workability of a control board, a widened movable zone of a column and a reduced installation space are achieved. The machining center includes a column movably supported on a column sliding portion in an X-axis direction, a work table movably supported on a table sliding portion in a Z-axis direction, a main spindle head slidably supported on the column in a Y-axis direction, and an automatic tool changer disposed at an inner side of the column sliding portion. The control board is arranged at an opposite side of the automatic tool changer and is provided in parallel with a side surface of a front portion of a table sliding portion and is arranged side by side with an openable/closable door for an operator provided on a side surface of a cover in a vicinity of a rear end portion of the side surface of the table sliding portion.Type: GrantFiled: October 23, 2008Date of Patent: November 5, 2013Assignees: JTEKT Corporation, Mitsui Seiki Kogyo Co., Ltd.Inventors: Kozo Imanishi, Yasukazu Yamaguchi, Yasutaka Uchimura, Masanao Kato

Patent number: 6082939Abstract: In a machine tool having a worktable feed mechanism of the type that a worktable is moved in a horizontal direction relative to a tool spindle along a pair of guideways in parallel with the horizontal direction, there is provided a cutting chips collection space formed between the pair of guideways fixed to a base. A pair of ball screws are arranged outside of the cutting chips collection space for moving the worktable relative to the tool spindle in the horizontal direction. The cutting chips and coolant generated by contacting a tool with a workpiece drop into the cutting chips collection space directly without being heaped onto a cover mechanism of the worktable feed mechanism.Type: GrantFiled: September 8, 1998Date of Patent: July 4, 2000Assignee: Toyoda Koki Kabushiki KaishaInventors: Kunimichi Nakashima, Tetsuo Teramura, Yasukazu Yamaguchi, Akiyoshi Tashiro, Hirotaka Imaizumi, Mitsuyoshi Taniguchi, Koji Toyama
