Patent number: 11935328Abstract: Iris image pick-up devices have the same field of view and are disposed at mutually different positions. An overall image pick-up device performs image pick-up over a wide field of view. A guiding device guides a subject. An illumination device illuminates the subject with light. The controller controls, using an image from the overall image pick-up device, at least one of reading out an image from the iris image pick-up devices, presenting at least of an image and a sound through the guiding device, or providing illumination with light from the illumination device.Type: GrantFiled: February 12, 2020Date of Patent: March 19, 2024Assignee: NEC CORPORATIONInventors: Keiichi Chono, Takahiro Toizumi, Masato Tsukada

Publication number: 20220308374Abstract: A liquid crystal display device includes a liquid-crystal display module, a holder, an exterior panel, and a fixing part. The liquid-crystal display module includes the liquid-crystal panel and a polarizing plate. The holder holds a back light that is glued to a back surface of the liquid-crystal display module. The exterior panel surrounds a periphery of the liquid-crystal display module. The fixing part fixes the holder and the exterior panel to each other in a part where a straight line and a periphery portion of the holder intersect with each other, the straight line extending in a direction that is different from a light-transmission-axis direction of the polarizing plate.Type: ApplicationFiled: October 12, 2020Publication date: September 29, 2022Applicant: DENSO TEN LimitedInventors: Takahiro TSUKADA, Kiyoshi TAKENO, Shogo FUCHISAKI, Keiji NEBIKI, Takeshi YASUDA, Haruya TSUGIMOTO

Patent number: 10790535Abstract: An electrode for a secondary cell includes a current collector and an electrode layer. The electrode layer has a gas flow passage disposed on the surface and/or in the interior of the electrode layer. The gas flow passage extends in the in-plane direction of the electrode layer. The electrode layer is made from an electrode layer forming material that contains an electrode active material and an ion conductive liquid and is a non-bonded body. A secondary cell comprises a power generation element having an electrolyte layer, a positive electrode disposed on a first surface side of the electrolyte layer, and a negative electrode disposed on a second surface side on the back of the first surface side of the electrolyte layer; and an outer casing that houses the power generation element. At least one of the positive electrode and the negative electrode is the electrode for a secondary cell.Type: GrantFiled: December 14, 2017Date of Patent: September 29, 2020Assignee: Nissan Motor Co., Ltd.Inventors: Takamasa Nakagawa, Hiroyuki Tanaka, Takahiro Tsukada, Hideaki Horie, Yuuki Kusachi, Yuusuke Emori, Yuusuke Mizuno

Patent number: 7991032Abstract: Disclosed herein is a laser driver including a light emission controlling section configured to stop generation of a control voltage by a control voltage generating section, causing a given voltage corresponding to a magnitude of a reference current to be outputted to an input node of a first emitter follower to operate the first emitter follower for a first time period from start of a light emission time period, release stop of the generation of the control voltage by the control voltage generating section, causing the control voltage to be outputted to the input node of the first emitter follower to operate the first emitter follower until end of the light emission time period of the laser, and operate a second emitter follower to discharge electric charges accumulated in the laser for a second time period after the end of the light emission time period of the laser.Type: GrantFiled: March 4, 2010Date of Patent: August 2, 2011Assignee: Sony CorporationInventors: Katsuhisa Daio, Takahiro Tsukada
