Patent number: 7862190Abstract: A surface light source device includes a light-emitting element which generates light, and a light guide plate which causes light emitted from the light-emitting element to be incident from an end face, causes the light to be reflected between opposite plate surfaces to guide the light along the plate surfaces and make the light emerge from the plate surfaces, and transmits light incident from one plate surface toward the other plate surface. A first optical element is placed on one plate surface side of the light guide plate, transmits part of light emerging from one plate surface of the light guide plate toward a front side, and returns the remaining light to a rear side. A second optical element is placed on the other plate surface side and transmits at least part of light emerging from the other plate surface side.Type: GrantFiled: October 24, 2007Date of Patent: January 4, 2011Assignee: Casio Computer Co., Ltd.Inventor: Hiroshi Higashiyama

Patent number: 7083317Abstract: An LED is mounted on a flexible wiring board, and this flexible wiring board is adhered by a both-surface adhesive tape to a back of a light guiding plate to which a light reflecting film is adhered by an adhesive layer. The LED is kept at a desired set position by retaining the LED by a retaining section formed integrally with the light guiding plate in a state where a light emitting surface of the LED air tightly contacts a light entrance end surface of the light guiding plate, and by adhering a rear surface of the LED to an inner surface of the retaining section by an adhesive agent.Type: GrantFiled: December 29, 2003Date of Patent: August 1, 2006Assignee: Casio Computer Co., Ltd.Inventor: Hiroshi Higashiyama

Patent number: 4936157Abstract: A rack and pinion type steering apparatus is provided with a rack guide made of synthetic resin. In the outer periphery of the rack guide, peripheral ribs are formed in the direction of its circumference and axial ribs are formed in its longitudinal direction, respectively. The space formed between those ribs and the inner periphery of a guide bore of the rack guide is set to be generally about the same as the space between a conventional rack guide made of sintered alloy and the inner periphery of the guide bore. As a result, at room temperature, each rib enables the same press performance as the conventional rack guide and the suitable reacting force at steering will be kept. Also at high temperature atmosphere, when each rib thermally expands and abuts the guide bore, the outer periphery excluding the portions of the ribs is thermally expanded, thus, thermal creep is prevented and stable engagement of the rack and pinion of the steering apparatus can be maintained at all times.Type: GrantFiled: April 19, 1989Date of Patent: June 26, 1990Assignee: Koyo Seiko Co., Ltd.Inventors: Yoshima Kotake, Keiichi Sakamoto, Hiroshi Higashiyama
