摘要:
A sheet material (1) includes a stiffness-increasing concave-convex part (20). A first reference plane (K1) and a second reference plane (K2) serve as a reference system. Numerous at least substantially (H) shaped first reference areas (213), each including two parallel longitudinal bar parts (214) and a latitudinal bar part (215) that connects center portions the two parallel longitudinal bar parts together, are arrayed with the same orientation in the second reference plane (K2). First areas (21) respectively protrude from the first reference areas (213) in the second reference plane (K2) toward the first reference plane (K1). Each first area (21) includes a first top surface (211), which is a reduced projection of its first reference area (213) into the first reference plane (K1), and first side surfaces (212) that connect the outer periphery of the first top surface (211) with the outer periphery of the corresponding first reference area (213).
摘要:
A sheet material (1) includes a stiffness-increasing concave-convex part (20). A first reference plane (K1), an intermediate reference plane (K3), and a second reference plane (K2) serve as a reference system. First unit areas (241) and second unit areas (242) are defined in the intermediate reference plane (K3). Each of the first unit areas (241) and the second unit areas (242) contains first virtual squares (243) and second virtual squares (244). Icosagonal areas that contain only adjacent first virtual squares (243) are designated as first reference areas (213), and icosagonal areas that contain only adjacent second virtual squares (244) are designated as second reference areas (223). The concave-convex part (20) contains first areas (21), which are formed based on the first reference areas (213), as well as second areas (22) and/or plane areas (23), which are formed based on the second reference areas (223).

A sheet material (1) includes a stiffness-increasing concave-convex part (20). A first reference plane (K1), an intermediate reference plane (K3), and a second reference plane (K2) serve as a reference system. First reference areas (213), which have a specific shape, and second reference areas (223), which are all areas other than the first reference areas (213), are disposed in the intermediate reference plane (K3). The concave-convex part (20) is formed of first areas (21) as well as second areas (22) and/or plane areas (23).
摘要:
A sheet material (1) has a concave-convex part (20). Using first, second and intermediate reference planes (K1, K2, K3) as a reference system, a virtual lattice longitudinally and laterally divides a unit area (23) disposed in the intermediate reference plane (K3) into n equal parts that are categorized as first boxes (231) and second boxes (232). A first reference area (213) contains a plurality of the first boxes (231), and a second reference area (223) contains a plurality of the second boxes (232). First areas (21) respectively protrude from the first reference areas (213) toward the first reference plane (K1). Second areas (22) respectively protrude from the second reference areas (223) toward the second reference plane (K2). Each of the first areas comprises a first top surface (211) and first side surfaces (212). Each of the second areas comprises a second top surface (221) and second side surfaces (222).

There is disclosed a permanent current switch which has a high temperature margin and which is thermally stable and which securely performs a switching operation between a superconducting state and a normal conducting state. The permanent current switch of the present invention has a coiled superconducting wire and a heater wire which switches the superconducting wire between the superconducting state and the normal conducting state, the superconducting wire is a magnesium diboride superconducting wire having a high-resistance metal on an outer side and a magnesium diboride superconducting portion on an inner side and prepared by forming a superconducting metal on a layer between the high-resistance metal and the magnesium diboride superconducting portion, and the permanent current switch further comprises a superconductive connecting section superconductively connected to a lead wire guided from the superconducting wire and a superconducting wire for a wiring line.
摘要:
In a metal sheath MgB2 superconducting wire, it is intended to achieve a wire having increased current density and a long length at the same time, by densitying superconducting core part. The superconducting wire is manufactured by forming diffusion hardened layer on the inner surface of the sheath such that the hardness of the inner surface becomes higher than that of the outer surface, filling MgB2 superconductor, and further if necessary, a critical current density increasing material such as indium, copper, and tin, in a metal sheath, to subject it to wire drawing. For the metal sheath, a material with toughness such as steel is used. Even if the sheath is made to a long wire, it does not break, thereby, enabling to density superconducting core part.
