Patent number: 9679668Abstract: A spent fuel storage rack that accommodates and stores spent fuels in a large number of cells formed in a grid pattern includes a flat rectangular plate-shaped base forming the bottom of the rack, columnar members extending upward from the four corners of the base, and at least a pair of upper and lower grid-shaped frame plates disposed above the base and fixed to and supported by the columnar members. Each of the cells is formed by assembling metal plates to which boron is added to a density greater than 1% into a polygonal tube, and the cells are arranged contiguously at fixed intervals in the grid-shaped frame plates.Type: GrantFiled: April 5, 2010Date of Patent: June 13, 2017Assignee: KABUSHIKI KAISHA TOSHIBAInventors: Toshimasa Mukai, Takao Sato, Hidenobu Hasegawa, Kaoru Takagi, Tetsuro Takeshita

Publication number: 20030020056Abstract: Disclosed is a method for building an overhead infrastructure capable of minimizing loads to utility poles, increasing suspension spaces on the utility poles, decreasing costs for constructing the overhead infrastructure, and improving an appearance and maintenance workability thereof. The method comprises a step of drawing a tensile line between utility poles, a step of putting around the tensile line a plastically deformable coil having a metal wire formed in a spiral shape and synthetic resin coated on a surface of the metal wire, a step of elongating the coil until its plastic deformation so as to form a basic construction with a series of overhead cableway capable of holding a plurality of overhead lines inside the spiral of the coil, and a step of extending an overhead line in an empty space of the overhead cableway on demand.Type: ApplicationFiled: November 7, 2001Publication date: January 30, 2003Applicant: Daimei Telecom Engineering Corp.Inventors: Takayuki Nimiya, Zenichi Komine, Akira Kuno, Norio Takemura, Katsunori Misaku, Kazue Misaku, Kaoru Takagi, Makiko Barker
