Patent number: 8659721Abstract: A liquid crystal display device capable of efficiently obtaining a high brightness with reduced unevenness in brightness using a single light-emitting section is provided. The liquid crystal display device includes: a liquid crystal panel for controlling display by changing orientation of a liquid crystal composition; a single cylindrical light-source section (634); and a reflecting section (636) provided so that the single cylindrical light-source section is sandwiched between the reflecting section and the liquid crystal panel, for reflecting the light emitted from the single cylindrical light-source section (634) toward the liquid crystal panel, in which at least a part of a sectional shape of a reflecting surface of the reflecting section (636) in a cross section perpendicular to an axial direction of the single cylindrical light-source section (634) is formed based on a parabola whose focal point is a position of the single cylindrical light source section (634).Type: GrantFiled: November 19, 2010Date of Patent: February 25, 2014Assignee: Panasonic Liquid Crystal Display Co., Ltd.Inventors: Toshiyuki Amimoto, Masaki Tsubokura, Tomohiro Maeyama

Patent number: 7367374Abstract: The present invention is directed to a display device that overcomes the limitation on tact time, and the defective phenomenon attributed to the generation of bubbles, pasting and visual irregularities at the time of laminating a film to a display panel. A polarizer is positioned in parallel to the vicinity of a main surface of a liquid crystal cell by holding two portions of the polarizer at suction stages. A portion of the polarizer is pushed and brought into contact with the main surface of the liquid crystal cell. From the portion of the polarizer, the polarizer is pushed to the main surface toward one end of the main surface along a first direction thereof. The polarizer is pushed to the main surface of the liquid crystal cell toward another end of the main surface in the first direction so as to laminate the polarizer to the main surface.Type: GrantFiled: November 23, 2004Date of Patent: May 6, 2008Assignees: Hitachi Displays, Ltd., Hitachi Display Devices, Ltd., Hitachi Display Technologies, Ltd.Inventors: Toshiyuki Amimoto, Tetsuya Takei, Toshihiko Saitou, Tetsuo Matsuzaki

Publication number: 20050109457Abstract: The present invention provides a manufacturing method and a manufacturing apparatus of a display device which can overcome the limitation on a tact time, and a defective phenomenon attributed to the generation of bubbles, pasting and visual irregularities at the time of laminating a film to a display panel thus manufacturing a display device having no bubbles, pasting and visual irregularities with high accuracy and at a high speed. A polarizer is positioned in parallel to the vicinity of a main surface of a liquid crystal cell by holding two portions of the polarizer at suction stages. Thereafter, a portion of the polarizer is pushed and brought into contact with the main surface of the liquid crystal cell. Then, from the portion of the polarizer, the polarizer is pushed to the main surface of the liquid crystal cell toward one end of the main surface of the liquid crystal cell along the first direction of the main surface of the liquid crystal cell.Type: ApplicationFiled: November 23, 2004Publication date: May 26, 2005Inventors: Toshiyuki Amimoto, Tetsuya Takei, Toshihiko Saitou, Tetsuo Matsuzaki

Publication number: 20050052587Abstract: The present invention can enhance the impact resistance in a display device provided with a lower frame having mounting portions. In a display device including a display panel and a lower frame which is arranged on a side opposite to a display screen of the display panel, the lower frame includes a body portion which is positioned on a back surface side of the display screen of the display panel, a mounting portion which projects toward the outside of the display panel, and a plurality of connecting portions which connect the body portion and the mounting portion. The plurality of connecting portions is folded toward the mounting portions from the body portion.Type: ApplicationFiled: September 7, 2004Publication date: March 10, 2005Inventors: Takaaki Kitada, Toshiyuki Amimoto

Patent number: 5371931Abstract: Software and hardware such as part feeding and assembling devices constituting a production system are simplified with the use of a plurality of processing and assembly integrated units in which processing and assembling of parts are coupled and integrated in accordance with products to be produced. The necessities for an automatic warehouse and an automated ground vehicle are eliminated by getting rid of futility of mere movements of the parts. A fundamental idea is that a production system is constructed of units in which three sections--a section for processing a raw material, a check functional section and an assembling section--are integrally combined in accordance with the products to be produced. The parts are processed, checked and assembled by single units just in time while targeting molded parts of plastic and pressed parts.Type: GrantFiled: September 8, 1992Date of Patent: December 13, 1994Assignee: Hitachi Ltd.Inventors: Takeshi Kawana, Toshiyuki Amimoto, Yasuhiro Fujita, Yuuji Enomoto, Tatsuya Niinomi, Sadao Ohara, Shin Hashizume, Yasuo Shibasaki, Tatsuhisa Matsunaga, Takeshi Yano

Patent number: 4934044Abstract: A method for wiring an electronic device including a plurality of electronic components and a plurality of connector elements for interconnecting the plurality of electronic components, the connector elements being arranged on the same plane in spaced relation to each other so as to define passages includes a number of steps. A first discrete line is connected to a surface of a first connector element such that the first discrete line extends on a first passage extending along the first connector element. Two pins are positioned along the first passage, substantially perpendicular thereto. The first discrete line is bent along the two pins, a distance between the at least two pins is then reduced, and the at least two pins are then moved away from the first passage. Similar, steps can be used to provide multiple discrete line between two connector elements or along the same passage between different connector elements.Type: GrantFiled: December 12, 1988Date of Patent: June 19, 1990Assignee: Hitachi, Ltd.Inventors: Hiroshi Hasegawa, Toshiyuki Amimoto, Mitsukiyo Tani
