Patent number: 7829494Abstract: A method for synthesizing carbon nanocoils with high efficiency, by determining the structure of carbon nuclei that have been attached to the ends of carbon nanocoils and thus specifying a true catalyst for synthesizing carbon nanocoils is implemented. The catalyst for synthesizing carbon nanocoils according to the present invention is a carbide catalyst that contains at least elements (a transition metal element, In, C) or (a transition metal element, Sn, C), and in particular, it is preferable for the transition metal element to be Fe, Co or Ni. In addition to this carbide catalyst, a metal catalyst of (Fe, Al, Sn) and (Fe, Cr, Sn) are effective. From among these, catalysts such as Fe3InC0.5, Fe3InC0.5Snw and Fe3SnC are particularly preferable. The wire diameter and the coil diameter can be controlled by using a catalyst where any of these catalysts is carried by a porous carrier.Type: GrantFiled: May 28, 2004Date of Patent: November 9, 2010Assignees: Japan Science and Technology Agency, Public University Corporation, Osaka Prefecture University, Otsuka Chemical Co., Ltd., Nissin Electric Co., Ltd.Inventors: Yoshikazu Nakayama, Lujun Pan, Toshikazu Nosaka, Osamu Suekane, Nobuharu Okazaki, Takeshi Nagasaka, Toshiki Goto, Hiroyuki Tsuchiya, Takashi Okawa, Keisuke Shiono

Patent number: 7651668Abstract: A material gas and a catalyst are introduced through a material supplying tube path and a catalyst supplying tube path together with a carrier gas into a reactor equipped on its outer periphery with a heat applicator for thermally decomposing the material gas. The reactor has a convention regulator fitted to the discharge end of the catalyst supplying tube path. The convection regulator covers an edge side of the reactor to regulate gas flow in the reactor so that the flow does not reach the edge side. Due to this, a convection state can be efficiently produced in a reaction region. Consequently, it becomes possible to prevent contamination defect caused by accumulation/adherence of concretion of catalyst, which was generated by aggregation of cooled catalyst in the low-temperature region of the reactor and a decomposition product of the material gas. Thus the efficiency of carbon nanostructure production can be improved.Type: GrantFiled: September 21, 2005Date of Patent: January 26, 2010Assignees: Japan Science and Technology Agency, Public University Corporation Osaka Prefecture University, Taiyo Nippon Sanso Corporation, Otsuka Chemical Co., Ltd., Nissin Electric Co., Ltd.Inventors: Yoshikazu Nakayama, Hiroyuki Tsuchiya, Yugo Higashi, Toshiki Goto, Keisuke Shiono, Takeshi Nagasaka, Nobuharu Okazaki

Patent number: 7649679Abstract: A photon pair generating device capable of further increasing generation efficiency of a correlation photon pair is provided, the photon pair generating device generating the correlation photon pair by a hyper-parametric scattering. A quantum well is provided in a resonator. An incident light radiated from a light source to the resonator resonates therein and becomes a particular resonator mode. The generation efficiency of the correlation photon pair by the hyper-parametric scattering in the quantum well is enhanced by disposing the quantum well in a position where electric field strength of the light becomes higher by this resonator mode.Type: GrantFiled: August 11, 2006Date of Patent: January 19, 2010Assignees: Japan Science & Technology Agency, Public University Corporation Osaka Prefecture UniversityInventors: Hiroshi Ajiki, Hajime Ishihara

Publication number: 20080063589Abstract: The subject invention provides a stable mass production method of carbon nano structure at low cost immune to variation of particle diameter of the catalyst microparticle in the catalyst material. The subject invention also provides a production device used for the method, and a new carbon nano structure having a conformation suitable for the mass production. The production method of carbon nano structure comprising fluidizing a material gas and catalyst microparticles in the reactor so that the material gas and the catalyst microparticles are brought into contact with each other, wherein said catalyst microparticles are suspended by the instantaneous spraying of the high-pressure gas, and then the suspension effect of the catalyst microparticles is stopped so that the catalyst microparticles naturally fall. The particle diameter of the catalyst microparticles is thus selected. With this arrangement, only the selected catalyst microparticles with the desired diameter are supplied to the reactor.Type: ApplicationFiled: July 13, 2005Publication date: March 13, 2008Applicants: JAPAN SCIENCE AND TECHNOLOGY AGENCY, PUBLIC UNIVERSITY CORPORATION OSAKA PREFECTURE UNIVERSITY, TAIYO NIPPON SANSO CORPORATION, OTSUKA CHEMICAL CO., LTD., NISSIN ELECTRIC CO., LTD.Inventors: Yoshikazu Nakayama, Takeshi Nagasaka, Toru Sakai, Toshiki Goto, Hiroyuki Tsuchiya, Keisuke Shiono, Nobuharu Okazaki
