Patent number: 8519336Abstract: The present invention provides an infrared sensor and an infrared sensor module having reduced noise, improved detection precision, and reduced manufacture cost. The infrared sensor includes a first substrate transmitting infrared light including at least one reduced-pressure and sealed cavity, at least one infrared sensing unit provided on the side of the first substrate, and at least one infrared sensing unit generating an output change. The infrared sensor includes a second substrate stacked on the first substrate with a recess, a reflection face capable of reflecting the infrared light, and at least one arithmetic circuit for amplifying or integrating an output, arranged in such a manner that the reflection face is sandwiched between the at least one sensing unit and the least one arithmetic circuit.Type: GrantFiled: December 28, 2010Date of Patent: August 27, 2013Assignee: OMRON CorporationInventors: Makoto Ohhira, Fumiji Aita, Yutaka Koyama, Sho Sasaki

Patent number: 7455443Abstract: A surface light source device capable of suppressing generation of bright line and preventing generation of crush of pattern forming on a light guide plate even when pressure is applied, includes a plurality of deflection patterns and diffusion patterns wherein the diffusion pattern is formed on the light source side of the deflection pattern. Further, the diffusion pattern is provided so as not to protrude outwards from the light guide plate from the plane opposite to the light-emitting plane and the diffusion pattern diffuses the light incident from a light guide direction to a direction different from the light guide direction seen from a direction perpendicular to the light emitting plane.Type: GrantFiled: July 21, 2006Date of Patent: November 25, 2008Assignee: OMRON CorporationInventors: Kenji Sakurai, Makoto Ohhira, Gouo Kurata, Yasuhiro Kawabata, Masayuki Shinohara

Patent number: 7434976Abstract: A double-side LCD having a surface light source device including a light guide plate and a light source facing one end face of the light guide plate. A plurality of deflection patterns are formed in a surface facing a light outgoing plane of the light guide plate, the deflection pattern includes an inclined plane facing the light source side and a re-incident plane substantially perpendicular to the light outgoing plane. Light from the light source is reflected by the inclined plane and outputted from the light outgoing plane to the LCD. A tilt angle (?) of the inclined plane satisfies: 45°?[Sin?1(Sin ?/n)]/2???45°+[Sin?1(Sin ?/n)]/2, wherein ? is an angle between a direction of peak brightness of outputted light and a direction perpendicular to the light outgoing plane, n is a refractive index of the light guide plate, and ? is within 6-15°.Type: GrantFiled: March 16, 2006Date of Patent: October 14, 2008Assignee: OMRON CorporationInventors: Kenji Sakurai, Makoto Ohhira, Gouo Kurata, Akihiro Funamoto, Shigeru Aoyama

Patent number: 7324179Abstract: A reflector is used in a display device and is disposed parallel to a predetermined plane, and has plural unit reflecting portions each having a reflection face for reflecting incident light in a direction different from that of regular reflection light of the predetermined plane. Further, the distance between a first tangential plane abutting on a first reflection face arranged in an arbitrarily extracted first unit reflecting portion at a reference point arranged in an arbitrary position on the first reflection face, and a second tangential plane abutting on a second reflection face arranged in a second unit reflecting portion adjacent to the first unit reflecting portion in parallel with the first tangential plane is preferably half or more of a coherent length of the incident light.Type: GrantFiled: February 27, 2004Date of Patent: January 29, 2008Assignee: Omron CorporationInventors: Makoto Ohhira, Motohiko Matsushita, Akihiro Funamoto, Shigeru Aoyama

Patent number: 7163330Abstract: According to a front light comprising an optical waveguide 25 and a light source 24 arranged on the side of the optical waveguide 25, the optical waveguide 25 comprises a light input surface and light emission surface 28, and a plurality of deflection patterns 26 are formed on the surface opposed to the light emission surface 28. Light from the light source 24 is input from the light input surface of the optical waveguide 25 and propagated in the optical waveguide 25. The light totally reflected by the deflection patterns 26 among the light propagated in the optical waveguide 25 is emitted from the light emission surface 28 in the direction oblique to the normal direction of the light emission surface 28. The light is emitted from the light emission surface 28 so as to be aligned in one direction regardless of its position.Type: GrantFiled: May 11, 2004Date of Patent: January 16, 2007Assignee: Omron CorporationInventors: Yuki Matsui, Makoto Ohhira, Motohiko Matsushita, Akihiro Funamoto, Shigeru Aoyama

Patent number: 7154576Abstract: A reflector used for a display device has a plurality of unit reflecting portions. The unit reflecting portions are arranged by repeating arrangement patterns of unit regions. The unit regions have a repetition pitch that is integral times the pitch of pixels of a liquid crystal display and more than 5000 ?m. More preferably, the repetition pitch of unit regions is integral times the pitch of pixels of a liquid crystal display and more than 10000 ?m.Type: GrantFiled: February 27, 2004Date of Patent: December 26, 2006Assignee: Omron CorporationInventors: Tomohiko Matsushita, Shigeru Aoyama, Makoto Ohhira, Motohiko Matsushita, Yasuhiro Kawabata
