Patent number: 7296419Abstract: To provide a cooling method of a superconducting cable line wherein moistures contained in the cable in the superconducting cable line after laid is removed before cooling, so that solidification of the moistures can be prevented from clogging of piping including a coolant flow channel and a return pipe. There is provided an inert gas generating vessel so that before the coolant is flown into the superconducting cable line 15, the inert gas is blown into the cable line from an inflow pipe 23 connected with a supply pipe 19? and is discharged from a discharge pipe 22 together with the gas. The inert gas is preheated by a heater 3 before feeding it into the cable line. The discharge pipe 22 connected with a discharge side B of the return pipe 19 is provided with a moisture measuring instrument 20 to measure a moisture content of the discharged gas.Type: GrantFiled: March 31, 2003Date of Patent: November 20, 2007Assignees: Sumitomo Electric Industries, Ltd., The Tokyo Electric Power Company IncorporatedInventors: Chizuru Suzawa, Takato Masuda, Kengo Ohkura, Yoshihisa Takahashi, Shoichi Honjo, Masato Shimodate, Yoshibumi Sato, Toshiyuki Uchiyama

Publication number: 20040005433Abstract: A MCP 1 according to the present invention is one in which outer circumferential glass 5 is disposed around channel glass 3 that is provided with a plurality of channels 7 in a long and thin hole shape and is formed in a plate shape. This channel glass 3 contains 35 to 55% of SiO2, 0 to 5% of Al2O3, 25 to 46% of PbO, 0.5 to 10% of &Sgr;(Li2O+Na2O+K2O), 0.1 to 8% of &Sgr;(Rb2O+Cs2O), 0 to 5% of &Sgr;(MgO+CaO+SrO+BaO), 0.1 to 7% of ZrO2, and 0 to 5% of Bi2O3 (all the above % are wt %). With such a composition, a sufficient glass network structure is formed in the channel glass 3. Moreover, the channel glass 3 can be sufficiently restricted from becoming porous, and moisture can be restricted from being adsorbed thereto. As results of these, a change with time, such as a “warp” can be sufficiently restricted from being generated even in a high-humidity environment.Type: ApplicationFiled: December 6, 2002Publication date: January 8, 2004Inventors: Masahiko Iguchi, Takeo Sugawara, Shigeki Matsuura, Yutaka Kusuyama, Toshiyuki Uchiyama
