Publication number: 20100280229Abstract: The present invention provides a polypeptide inducing the production of an antibody in permucosal administration in the presence of no immunological adjuvant, a composition containing the polypeptide, and use thereof. The present invention solves the above object by providing a polypeptide inserted with a cell attachment motif of a cell adhesive molecule to the peptide which has an amino acid sequence of multiagretope type T cell epitope at the amino terminal side of an inserted linker peptide, and an amino acid sequence of a B cell epitope at the carboxyl terminal side of the inserted linker peptide, a composition containing the polypeptide, and use thereof.Type: ApplicationFiled: July 19, 2010Publication date: November 4, 2010Applicant: KABUSHIKI KAISHA HAYASHIBARA SEIBUTSU KAGAKU KENKYUJOInventor: Toshiki NISHIZAWA

Patent number: 7599587Abstract: In a wavelength selective switch according to the present invention, an isolator is disposed between a lens array and a first lens. The isolator includes an isolator element and a transmitting means. The isolator is disposed so that the isolator element is on light paths of input lights and that the transmitting element is on a light path of an output light. The isolator element is shared among the light paths of the plurality of input lights. The isolator element intercepts lights propagating in an opposite direction to the input lights and prevents coupling of the lights to input ports. The transmitting element transmits the output light and couples it to an output port.Type: GrantFiled: August 29, 2008Date of Patent: October 6, 2009Assignee: NTT Electronics CorporationInventors: Toshiki Nishizawa, Kenji Kobayashi, Yuji Mitsuhashi, Hiroshi Tomita

Patent number: 7413355Abstract: A light emitting module according to the present invention is characterized in that a light emitting device and a light-emission-side lens are held close to each other by a holding part extended from part of a stem in parallel with outgoing light of the light emitting device, and light emitted from the light emitting device is refracted. A single-fiber two-way optical communication module according to the present invention has the light emitting module and, in addition, collimate lenses close to an optical fiber and a light receiving device, and is characterized in that splitting of light to a light receiving module or coupling of light from the light emitting module is performed with parallel rays. Each of the collimate lenses condenses the parallel rays to an incident/outgoing end face of the optical fiber, condenses the parallel rays to a light receiving face of the light receiving device, and outputs, as parallel rays, outgoing light from the light emitting module.Type: GrantFiled: June 13, 2006Date of Patent: August 19, 2008Assignee: NTT Electronics CorporationInventors: Toshiki Nishizawa, Yuji Mitsuhashi, Toshiaki Uchida

Patent number: 7364370Abstract: An optical receptacle according to the invention includes a columnar stub ferrule having an optical fiber inserted into a center line connecting both opposite end faces; a cylindrical sleeve into which a part of the stub ferrule is inserted; and a housing in which a through hole is formed, which houses the stub ferrule and the sleeve in the through hole, which holds a part on a side on which the stub ferrule is not inserted into the sleeve, with a projecting portion formed in the through hole, and which surrounds a side surface of the stub ferrule on the side on which the stub ferrule is not inserted into the sleeve. The optical receptacle has a space between the side surface of the stub ferrule on the side on which the stub ferrule is not inserted into the sleeve and an inner peripheral surface of the housing opposing the side surface.Type: GrantFiled: August 21, 2006Date of Patent: April 29, 2008Assignee: NTT Electronics CorporationInventors: Toshiki Nishizawa, Kenji Kobayashi

Publication number: 20080003186Abstract: It is intended to provide an effective cariostatic material which inhibits dental plaque formation as well as onset of dental carries. A material for inhibiting enamel demineralization containing, as the active ingredient, a proanthocyanidin-like polyphenol originating in hop bract or immature apple, which effectively inhibits not only dental plaque formation but also the dental caries process including proliferation of bacteria, formation of acids by the bacteria and enamel demineralization. Also, foods, drinks and oral care goods with the use of the above substance as an enamel demineralization inhibitor are provided.Type: ApplicationFiled: July 3, 2007Publication date: January 3, 2008Applicant: Asahi Breweries, Ltd.Inventors: Susumu IMAI, Motoyuki Tagashira, Tomomasa Kanda, Toshiki Nishizawa, Nobuhiro Hanada
