摘要： A tunneling Josephson junction is disclosed in which first and second superposed superconducting electrode layers are formed of thin films of oxide superconducting materials having a perovskite structure of BaPB.sub.1-x Bi.sub.x O.sub.3. A barrier layer interposed between these superconducting electrode layers is a thin film of long service life which is stable and breakdown free under heat cycles from room temperature to ultra low temperatures. This film is made of an oxide with perovskite structure which has the same crystal structure and thermal expansion coefficient as those of the first and second superconducting layers for functioning as an insulator or a semiconductor. The oxide with perovskite structure may be BaSnO.sub.3, Ba.sub.1-y Sr.sub.y Pb.sub.1-x Bi.sub.x O.sub.3 (wherein 0.ltoreq.x.ltoreq.0.3, y>0.3) or BaPb.sub.1-x (A.sub.1-y Bi.sub.y)O.sub.3 (wherein A is at least one member selected from the group consisting of V, Nb, Ta and Sb; 0.1.ltoreq.x.ltoreq.0.3; and 0.ltoreq.y.ltoreq.0.5).

摘要： In a stator core is formed by laminated strip-shaped straight cores including a plurality of teeth portions, bent portions being provided with V-shaped notches, which define V-shaped gaps opened to one direction and interposing between each of the teeth portions, the straight cores being formed into an annular configuration by bending the bent portions in a direction so as to close the V-shaped notches and circular holes being provided at the bent portions so as to form a series of gaps between each of the teeth portions. The straight cores further include deformation preventing portions formed on the bent portions by cutting off a part of a pair of oblique lines defining the V-shaped notches toward the circular holes so as to expand the gaps of the V-shaped notches and the circular holes for preventing the bent portions from deforming by stress of bending process.

摘要： A motor includes a cylindrical stator. The stator includes a stator core having teeth, which project inwardly in the radial direction, and coils, which are formed by winding a conductive wire onto each tooth with first and second insulators. The first insulator includes a support extending axially from an outer restriction wall. Each of first to third bus bars is supported by the support of the first insulator in a state in which a main portion is exposed. The main portions of the first to third bus bars are thus in contact with ambient air.

摘要： In a method of manufacturing a thin film of a compound oxide, different types of materials for forming the compound oxide are evaporated in vacuum. The evaporated materials are heated and deposited on a substrate to form a thin film. An oxygen ion beam having energy of 10 to 200 eV is implanted in the thin film which is being formed on the substrate. Alignment of the constituting elements is performed on the basis of a substrate temperature and energy of the oxygen ion beam, thereby causing epitaxial growth.
