Patent number: 6668172Abstract: A reception apparatus and a reception processing method are proposed to improve a reception characteristic by compensating deterioration of transmission quality independently of the traveling speed of a terminal. When a transmission signal sent via a radio transmission path is received and data is demodulated by carrying out various kinds of reception processing on the received signal, the present invention can perform reception processing best suited to a radio transmission path whose state changes according to the traveling speed of the terminal itself by receiving traveling speed information from speed detection means for detecting the traveling speed of the terminal itself and controlling reception processing on the reception signal according to the traveling speed information.Type: GrantFiled: October 27, 2000Date of Patent: December 23, 2003Assignee: Sony CorporationInventor: Osamu Yoshimura

Lenticular lens sheet capable of reducing color shift and improving overall light team transmittance
Patent number: 6101031Abstract: A lenticular lens sheet capable of reducing the color shift and improving the overall light beam transmittance. The lenticular lens sheet has an incident side lenticular lens on its light beam incident side surface and further has an emergent side lenticular lens on its emergent side surface, with peak portions of the emergent side lenticular lens being formed at substantially convergent positions of the incident side lenticular lens.

Patent number: 5751478Abstract: A rear-projection screen having at least a Fresnel lens and a light-diffusing member, and is characterized by having vertical-direction light diffusion properties greater at its upper and lower end portions than at its middle portion. For example, the light-diffusing member contains light-diffusing fine particles and has a vertical lenticular lens that diffuses light in the vertical direction, provided on the light-incident surface of the Fresnel lens. This decreases the rainbows caused by misdirected light and also improves the brightness at the border, without causing a lowering of peak gain.Type: GrantFiled: April 3, 1996Date of Patent: May 12, 1998Assignee: Kuraray Co., Ltd.Inventors: Osamu Yoshimura, Ichiro Matsuzaki

Patent number: 5749035Abstract: A conveying guide for conveying a sheet onto which an image has been transferred is made of a synthetic resin having a resistance higher than the resistance of the transfer sheet. The upstream side end of the upper surface of the conveying guide is located sufficiently lower than the position at which the sheet is separated from the surface of the photoreceptor drum. With these arrangements, the charging of the conveying guide due to the friction between the sheet and the guide is prevented, thereby restraining the image quality deterioration.Type: GrantFiled: October 10, 1996Date of Patent: May 5, 1998Assignee: Mita Industrial Co., Ltd.Inventors: Keiji Ban, Tetsuro Tomoe, Masami Fuchi, Hiroaki Tsuchiya, Osamu Yoshimura, Shinichi Tanaka

Patent number: 5479357Abstract: A circuit designing system improves precision of fan out checking and further improves reasonableness of construction and consistency of derivation of a wiring capacity. Therefore, wiring lengths of respective wiring connected to respective output terminals of the circuit element of an objective circuit to be designed is predicted on the basis of a circuit design information and the wiring capacity is derived on the basis of the predicted wiring length. In the alternative, the wiring capacity is derived on the basis of the wiring length of respective wiring determined as a result of layout designing. The wiring capacity thus derived is used only for fan out checking, but also for logic synthesizing and logic simulation.Type: GrantFiled: November 1, 1994Date of Patent: December 26, 1995Assignee: NEC CorporationInventor: Osamu Yoshimura

Patent number: 5432636Abstract: In a rear-projection screen comprising a Fresnel lens and a light-diffusing member such as a lenticular lens sheet, a rise angle in a central region of the Fresnel lens is smaller than a rise angle in an intermediate region thereof (e.g., the former is not larger than 3.degree. and the latter is larger than 3.degree. ). The rise angles may preferably gradually increase from the central region of the Fresnel lens toward the intermediate region thereof. The central region of the Fresnel lens may preferably be a region extending within the range of from 1/4 to 1/3 from the middle point of a diagonal of the rear-projection screen. Such a Fresnel lens is effective for improving white uniformity in the intermediate region of the rear-projection screen and eliminating color corn in the central region thereof.Type: GrantFiled: May 31, 1994Date of Patent: July 11, 1995Assignee: Kuraray Co., Ltd.Inventors: Masaki Ishii, Yoshihiro Kumagai, Osamu Yoshimura, Ichiro Matsuzaki, Shinichi Asano, Takao Kibushi

Patent number: 5424818Abstract: A transferring apparatus transfers a toner image formed on the surface of a photoreceptor drum onto a sheet. The photoreceptor drum surface and a transfer roller are arranged in such manner that a gap larger than the thickness of the sheet is left between the photoreceptor drum and transfer roller, and a lower guide member for guiding the sheet in such direction that the sheet abuts the drum surface at a predetermined angle is arranged between a resist roller pair and the drum. The sheet which abuts the drum surface by way of the upper surface of the guide member is in close contact with the drum surface while being bent and deformed along the drum surface. A conveying roller is provided, opposite the upper surface of the lower guide member, with a predetermined gap between, at a position close to but out of contact with the drum surface. The conveying roller may also be arranged to contact the transfer roller.Type: GrantFiled: November 24, 1993Date of Patent: June 13, 1995Assignee: Mita Industrial Co., Ltd.Inventors: Osamu Yoshimura, Shigeki Hayashi, Hiroshi Ishida, Hiroshi Kubota, Yasuo Hatade, Masahiro Hashizume, Hiroyuki Ueda, Tadakazu Ogiri

Patent number: 5127644Abstract: A conveying roller conveying a paper has a stepped structure with the diameter of portion positioned at the middle in the axial direction of the conveying roller slightly larger than that on opposite sides or ends of the conveying roller. The center in the axial direction of such middle portion almost coincides with the center in the axial direction of a paper-supplying roller positioned upstream of the conveying roller. The promotion of the inclined conveyance of paper resulting from inclined supplying to the conveying roller is prevented, particularly in the case of a one-end standard paper-supplying mode wherein one side end in the direction of the width of paper is regulated by a paper-supplying guide. The middle roller portion is displaced axially toward the side of the paper-supplying guide. The forces of two springs for urging an image-read out device toward the conveying roller to be almost equal to each other.Type: GrantFiled: July 12, 1990Date of Patent: July 7, 1992Assignee: Mita Industrial Co., Ltd.Inventors: Takeo Yoshihiro, Hiroyoshi Ohmura, Kazuo Nakamura, Osamu Yoshimura, Masayuki Mizuno

Patent number: 5093739Abstract: This invention relates to an STN liquid crystal display device and a retardation means, in which coloring caused by wavelength dependency of a birefringent effect is compensated for and decolored by using a novel combination of retardation films. At least a pair of retardation films manufactured by stretching a polymeric film and having positive and negative intrinsic birefringence values are arranged such that their main stretching directions cross each other. Coloring is decolored and at the same time viewing angle dependency of display is minimized by this arrangement. Decolored black-and-white display having small viewing angle dependency can be obtained, bright display with less light absorption is realized, and the thickness of the display device can be decreased.Type: GrantFiled: April 29, 1991Date of Patent: March 3, 1992Assignee: Citizen Watch Co.Inventors: Kazuhiko Aida, Osamu Yoshimura, Motonao Arai, Satofumi Koike
