Patent number: 11245174Abstract: The housing includes a first base portion and a second base portion which are conductive respectively. The first base portion and the second base portion are disposed in contact. The antenna element is connected to the antenna ground. The antenna ground is formed on the antenna board. The gasket is located between the first base portion and the antenna ground in a height direction of the housing, and is conductive. The fixing member fixes the second base portion and the antenna ground so that the second base portion and the antenna ground are electrically connectable to each other in a state where the gasket is in contact with the first base portion and the antenna ground.Type: GrantFiled: June 24, 2019Date of Patent: February 8, 2022Assignee: DYNABOOK INC.Inventors: Toshiyuki Hirota, Hikaru Hirata, Tomofumi Miyamoto, Shingo Koide

Patent number: 11018407Abstract: According to a notebook-sized personal computer of an embodiment, a base housing retains an arithmetic unit, an antenna having antenna elements, and covers. An LCD housing retains an LCD. Hinges rotatably couple the base housing and the LCD housing to each other. In the base housing, a pair of depression sections are formed by depressing both ends of one side thereof. In each of the pair of depression sections, an antenna element is accommodated. On the base housing, to end sections respectively adjacent to the pair of depression sections along the one side of the base housing, the hinges are respectively provided. The covers respectively accommodate each of the antenna elements, and are constituted of a material through which a radio wave is passed.Type: GrantFiled: December 27, 2018Date of Patent: May 25, 2021Assignee: Toshiba Client Solutions CO., LTD.Inventors: Toshiyuki Hirota, Takeshi Iwata, Kazuya Fukushima, Yusuke Sugiura, Tomomi Murayama, Shogo Maeshima, Tomofumi Miyamoto, Shingo Koide, Hikaru Hirata

Patent number: 7154705Abstract: A magnetic head for a rotary head drum is disclosed which can suppress abrasion thereof while a sufficient contact thereof with a magnetic tape is secured. An upper side tape sliding surface and a lower side tape sliding surface are formed on a tape sliding surface at an end of a head chip on the opposite upper and lower sides of a central tape sliding surface, which has a magnetic gap thereon, with a pair of upper and lower grooves left therebetween. The upper side tape sliding surface which is brought into contact with a magnetic tape earlier than the central tape sliding surface is formed with an increased thickness while the lower side tape sliding surface which is brought into contact with the magnetic tape later than the central tape sliding surface is formed with a decreased thickness.Type: GrantFiled: December 22, 2005Date of Patent: December 26, 2006Assignee: Sony CorporationInventors: Masahiro Kanaguchi, Jiro Fujiwara, Hikaru Hirata
