摘要： PURPOSE:To obtain a Tl-Pb oxide superconducting material with the crystal structure consisting essentially of a 1223 phase and/or a 1234 phase and with the critical current density improved when energized in a magnetic field by using a precursor powder consisting essentially of a 1212 phase as the raw material. CONSTITUTION:A precursor powder consisting of a Tl-Pb 1212 phase shown by formula I or the 1212 phase and Ca2PbO4 is prepared.

摘要： PURPOSE:To prevent cracking of sealing glass, by providing roundness having a required radius of curvature at the peripheral part of a lead part after blanking, thereby removing stress concentration to the peripheral part of the lead part. CONSTITUTION:The cross sectional shape of a lead part 8 of a part sealed with sealing glass 3 is made to be an approximately rectangular shape by chemical polishing and the like as a whole. The lead part is formed by a flat part, which has a width of 50mum or more and is used for wire bonding, and a peripheral part, which has roundness with the radius of curvature of 0.2mum or more. Then, thermal stress is not concentrated to the sealing glass, which is closely contacted with the lead part 8. Thus, cracking of the sealing glass can be prevented.

摘要： PROBLEM TO BE SOLVED: To provide a Mg-Ni based hydrogen storage alloy sheet which consists of a tape- or sheet-like sintered compact combined with a good electric conductor, is easily producible, has high energy density per weight and is rapidly chargeable and dischargeable.
SOLUTION: Using Cu, a Cu alloy, Ni or an Ni alloy as a core material, an Mg-Li alloy sheet and an Ni or Ni alloy sheet consisting essentially of Ni are rolled on the core material to produce a jelly roll of a multilayer structure of Mg-Li/Ni (S101). The jelly roll is inserted into a Cu pipe and extruded (S102, S103), is subjected to wire drawing (S104, S105), and is further subjected to rolling (S106) so as to form a sheet or tape. Further, heat treatment (S109) is applied to produce an Mg-Ni alloy.

摘要： PROBLEM TO BE SOLVED: To maintain superconductive connecting state in a magnetic field, and obtain characteristics of critical current value or more of an oxide superconductive material unit by wrapping the end of one composite body in the end of the other composite body with a specified width of wrapping part for heat-treating at least once after that. SOLUTION: Composite bodies 3a and 3b are formed by forming oxide superconductive precursor layers 2a and 2b on the surface of bases 1a and 1b. Next, when each of the composite bodies 3a and 3b is folded and wrapped with the oxide superconductive precursor layers inside, the end of one composite body 3a is wrapped into the end of the other composite body 3b with a specified width of wrapping part D. Finally, the material formed by wrapping a part of the composite body 3b with the composite body 3a is heat-treated at least once. Thereby, the adjacent oxide superconductive precursor layers 2a and 2b are partially dissolved to be oxide superconductive layers, and oxide superconductive layers of the composite bodies 3a and 3b are joined to be oxide superconductive material.
