Abstract: At least part of constituent yarns extending in the warp direction outside and adjacent a core thread woven or knitted in an element attachment edge portion has a higher elongation recovery ratio R than all the other constituent yarns and the core threads extending in the warp direction, the elongation recovery ratio R being expressed by the following equation based on a measurement according to JIS L1096:

Abstract: Dyed, colorless transparent, or semi-transparent yarns or dyed transparent or semi-transparent yarns are used in combination as composition yarns of a belt to be woven or knitted. Consequently, color of the dyed yarns can be seen through the transparent yarns at intersections of the both yarns, so that beautiful intersections are produced. Further, the belt having a specific color tone produced by mixing various colors may be obtained. If it is intended to change the color of the belt, the belt having a desired color can be produced easily only by changing part of the composition yarns.

Abstract: In a fastener tape having a tape main portion obtained by weaving and an element-mounting edge portion in which core strings are woven, foundation warps used for the tape main portion have a lower thermal contraction coefficient than the other warps. The core strings have a high thermal contraction coefficient. The warps adjacent to the core strings at an inner side thereof have a thermal contraction coefficient lower than that of the core strings. Therefore, it is possible to obtain a fastener stringer in which no puckering occurs in an element-mounting edge portion even after elements are attached, so that linearity can be secured.

Abstract: A slide fastener which permits easy attachment of electric conductors and ensures supply of electric current to all metallic coupling elements even if a part of the electric conductors is cut off. And it has a neat appearance because the electric conductors exposed in spaces among the coupling elements do not look unsightly. In the slide fastener having a fastener tape, a core cord and metallic coupling elements disposed along a longitudinal edge of one side of the fastener tape, a plurality of electric conductors are used as a part of warps of the fastener tape, and the exposed portions of the electric conductors are shifted one another in the longitudinal direction. Therefore, the electric conductors are substantially continuously exposed on the front surface of the fastener tape along the outer edge of the core cord and weaved in the fastener tape body.

Abstract: A superconducting magnet which is capable of improving the refrigerating and the assembling characteristics and of composing in small size. A helium vessel 2 contains a cylindrical superconducting coil for cryogenically refrigerating it by liquid helium. A second and a first heat-shields 5 and 6 and a vacuum vessel 4 are coaxially provided so as to surround the helium vessel 2. Over the helium vessel 2, a L-letter shaped duct 50 is provided to be exposed to helium gas atmosphere being evaporated in the helium vessel 2. A refrigerator-mounting cylinder 51 has an end coupled to the L-letter shaped duct 50 through the bellows 52 and is mounted on an end surface of the vacuum vessel 4 substantially in parallel to the axial direction of the superconducting coil. A three-stage cold heat accumulation refrigerator 30 is inserted into and fixed to the refrigerator-mounting cylinder 51 for reliquefying the helium gas having been drawn into the L-letter shaped duct 50 by a third heat state 43.
