Patent number: 11613683Abstract: There is provided a production method of a chain silica particle dispersion. This production method includes a dispersion preparation step of hydrolyzing alkoxysilane in the presence of ammonia to prepare a silica particle dispersion, an ammonia removal step of removing the ammonia from the silica particle dispersion such that an ammonia amount relative to silica contained in the silica particle dispersion is 0.3% by mass or less, and a hydrothermal treatment step of hydrothermally treating the silica particle dispersion having a silica concentration of 12% by mass or more, from which the ammonia has been removed, at a temperature of not lower than 150° C. and lower than 250° C. An abrasive including such chain silica particles is high in polishing rate and excellent in polishing properties.Type: GrantFiled: December 27, 2018Date of Patent: March 28, 2023Assignee: JGC CATALYSTS AND CHEMICALS LTD.Inventors: Miki Egami, Masanobu Taniguchi, Mitsuaki Kumazawa, Ryo Muraguchi

Patent number: 10358353Abstract: Silica particles calcined in a calcination step are supplied in a swirling flow generated by a gas introduced in a disintegration container and disintegrated therein, whereby the silica particles can be easily disintegrated and there can be obtained disintegrated silica particles having both low hygroscopicity and high dispersibility in resin. In addition, the introduction of dehumidified air (gas) during the disintegration reduces hygroscopicity and greatly improves dispersibility in resin. Furthermore, performing heating treatment (calcination) again after the disintegration causes the surface modification of the disintegrated silica particles, greatly improving hygroscopicity and dispersibility in resin. The resin composition obtained in this manner including silica particles provides good injectability and filterability when used for an underfill material for semiconductors and an in-plane spacer or sealing spacer of liquid crystal displays.Type: GrantFiled: August 1, 2014Date of Patent: July 23, 2019Assignee: JGC Catalysts and Chemicals Ltd.Inventors: Ryo Muraguchi, Miki Egami, Mitsuaki Kumazawa, Masanobu Taniguchi, Tsuguo Koyanagi, Michio Komatsu, Kazutaka Egami

Patent number: 6837549Abstract: A light alloy wheel for a vehicle comprising a disc portion comprising a hub portion and a design portion and a rim portion, the design portion having as-die-cast spoke portions having a taper angle of less than 5.0°. This wheel can be produced by using a casting apparatus comprising a die assembly comprising at least a stationary lower die and a movable upper die, a movable platen to which the upper die is fixed, a first cylinder and at least three synchronous second cylinders mounted onto a frame of the apparatus for moving the movable platen; driving the first cylinder to slowly reduce the clamping force of the lower die and the upper die; synchronously driving the second cylinders to elevate the movable platen in parallel from a position at which the lower die and the upper die are clamped to a position at which the wheel would not impinge on the lower die even if the movable platen were slanted; and then further elevating the movable platen by the first cylinder.Type: GrantFiled: January 10, 2002Date of Patent: January 4, 2005Assignee: Hitachi Metals, Ltd.Inventors: Hajime Ito, Minoru Kanai, Masanobu Taniguchi, Kenji Usui

Publication number: 20030197830Abstract: Disclosed is a double-fronted eyeglass frame comprising an eyeglass frame having a front and two temples hinged to its opposite side joints, and a detachable front to be detachably attached to the front of the eyeglass frame. The bridge of the front of the eyeglass frame has magnets fixed to its opposite rear extensions, and likewise, the bridge of the detachable front has magnets fixed to its opposite rear extensions. The bridge of either front has guide pieces attached to its rear extensions, thereby permitting the magnets of the detachable front to be put on those of the front in correct position when the detachable front is hung on the front of the eyeglass frame.Type: ApplicationFiled: November 20, 2002Publication date: October 23, 2003Inventor: Masanobu Taniguchi
