Patent number: 7522078Abstract: The length portion of part of a multiband superconductor line 10 is used as a closed circuit line part Rc that constitutes part of a closed circuit allowing passage of an electric current Io generated by an electric current source 12. Meantime, the line part extending and continuing into the closed circuit line part Rc is used as an open circuit line part Ro adapted to serve as an open circuit regarding the electric current source 12. By keeping the multiband superconductor line 10 under a temperature environment falling short of the critical soliton temperature and injecting a nonequilibrium electric current Io from the electric current source 12 into the closed circuit line part of the multiband superconductor line, it is rendered possible to induce generation of an interband phase different soliton So. The generated interband phase difference soliton So is forwarded as separated from the electric current Io to the open circuit line part Ro and is made to run therein.Type: GrantFiled: August 27, 2007Date of Patent: April 21, 2009Assignee: National Institute of Advanced Industrial Science and TechnologyInventors: Yasumoto Tanaka, Akira Iyo, Adrian Crisan, Kazuyasu Tokiwa, Tsuneo Watanabe, Norio Terada

Patent number: 7104017Abstract: Outer cables disposed in a box girder in the longitudinal direction of a box girder bridge to prestress the box girder each have a transparent sheath made of a transparent polyethylene resin, vinyl chloride resin, polypropylene resin or the like, thereby allowing the grouting condition in the sheath to be inspected reliably and easily. If a colored grout is filled, the filling condition can be inspected even more reliably and easily. In addition, it is possible to readily find a portion left unfilled after the grout has hardened and to refill it for repairing by using openings for injection and ejection made at each side of the void left.Type: GrantFiled: May 15, 2000Date of Patent: September 12, 2006Assignees: Anderson Technology Corporation, Sumitomo Electric Industries, Ltd., Shinko Wire Company, Ltd., Berger/ABAM Engineers, Inc.Inventors: Tsutomu Kadotani, Norio Terada, Yoshitaka Nishida, Takashi Takagaki, Toshikazu Minami

Patent number: 6655104Abstract: A joint made between prestressing strands with a prestressing strand coupler is covered with a transparent coupler sheath having a retarded-hardening resin filling material injection opening and discharge opening provided in a tube wall thereof, and a resin filling material is injected into the transparent coupler sheath from the injection opening to fill the coupler sheath with the filling material. Thereafter, the whole outer peripheral portion of the prestressing strand joint, including the coupler sheath, is embedded with placed concrete. Tension is applied to the prestressing strands after the concrete has hardened and before the resin filling material hardens, thereby completing an excellent prestressing strand joint structure. According to the present invention, the filling condition of the resin filling material in the coupler sheath around the prestressing strand joint can readily be confirmed by visual observation.Type: GrantFiled: October 30, 2001Date of Patent: December 2, 2003Assignee: Anderson Technology CorporationInventors: Tsutomu Kadotani, Yasuo Inokuma, Norio Terada, Hideaki Sakai, Toshikazu Minami, Jun Yamazaki, Yoshitaka Nishida
