Publication number: 20240085831Abstract: The present invention relates to an image heating apparatus that includes a heater including a plurality of independently controllable heating blocks in a longitudinal direction thereof, each including a first conductor, a second conductor, and a heating element. At least one of electrodes corresponding to the respective heating blocks is disposed in an area where the heating element is located in the longitudinal direction on a second surface of the heater that is opposite to a first surface that comes into contact with an endless belt. An electrical contact is arranged so as to face the second surface of the heater. An overheating occurring in a no-media passage portion when an image formed on a recording material having a small size is heated is suppressed or reduced.Type: ApplicationFiled: November 20, 2023Publication date: March 14, 2024Inventors: Yasuhiro Shimura, Koji Nihonyanagi, Ryota Ogura

Patent number: 10186368Abstract: Disclosed herein is a coil component that includes a base, a metal wire that is wound around the base and contains copper, and a terminal electrode that is provided on the base and contains nickel and tin. The terminal electrode includes a wire connection area to which an end portion of the metal wire is connected and which contains a CuNi alloy or a CuNiSn alloy, and a mounting area which is different from the wire connection area. The wire connection area includes a portion that contains a small amount of tin than the mounting area.Type: GrantFiled: November 21, 2016Date of Patent: January 22, 2019Assignee: TDK CORPORATIONInventors: Nobuo Takagi, Setu Tsuchida, Koji Shimura

Patent number: 10170234Abstract: A coil device includes a magnetic core and terminal electrodes. The terminal electrodes include attachment pieces, wire connection rising pieces, connection pieces, and fillet forming pieces. The wire connection rising pieces are integrally risen from one ends in a longitudinal direction of the attachment pieces along a side surface in the X-axis direction of a flange. The connection pieces are integrally formed with upper end sides of the wire connection rising pieces and have welded balls connected to lead parts of a wire by laser welding. The fillet forming pieces are integrally risen from one ends in a lateral direction crossing the longitudinal direction of the attachment pieces along a side surface in the Y-axis direction of the flange. Laser shielding members are arranged between the welded balls and the flange of a magnetic core.Type: GrantFiled: January 21, 2016Date of Patent: January 1, 2019Assignee: TDK CORPORATIONInventors: Hiroyuki Iwata, Nobuo Takagi, Hiroyuki Abe, Koji Shimura

Patent number: 7800476Abstract: A coil component having a core, first and second terminal electrodes provided on the core, and a conducting wire having a winding portion provided on the core and end portions electrically connected to the first and second terminal electrodes to provide first and second connecting portions. The core has one side surface at which the first and second connecting portions are provided. When viewing the one side surface, a wire portion in the winding portion extends in a first direction, and a wire portion extending from the second connecting portion extends toward the winding portion in a second direction. The first and second directions define an intersection angle of not more than 90 degrees.Type: GrantFiled: April 24, 2009Date of Patent: September 21, 2010Assignee: TDK CorporationInventors: Daisuke Urabe, Yasuhiko Kitajima, Takashi Ishii, Hitoshi Sasaki, Koji Shimura, Yoshiyuki Takanashi

Patent number: 7037312Abstract: An intraocular-lens insertion device is adapted to deform a deformable intraocular lens into a smaller size and insert the intraocular lens into an eye via an insertion tube. An intraocular-lens guide is provided on the inner surface of the insertion tube. The guide may be a rail-shaped projection or a groove, which extends parallel to a direction along which the intraocular lens is pushed out. A stress release structure is provided on the insertion tube in order to release stress of the intraocular lens produced due to deformation thereof. Moreover, a frictional-resistance increasing structure is provided on the inner surface of the insertion tube to be located in the vicinity of the stress release structure. The frictional-resistance increasing structure increases frictional resistance between the inner surface of the insertion tube and the intraocular lens. The frictional-resistance increasing structure may be a roughened surface which completely or partially covers the inner surface of the insertion tube.Type: GrantFiled: August 16, 2002Date of Patent: May 2, 2006Assignee: Canon-Staar Co., Inc.Inventors: Toshikazu Kikuchi, Kenichi Kobayashi, Hidenori Yoshida, Koji Shimura
