  • Patent number: 8880135
    Abstract: The present invention is configured such that, in a low AC loss oxide superconductor constituted by providing an oxide superconducting layer 6 on a substrate 1, said oxide superconducting layer 6 is separated into a plurality of filament conductors 2 in parallel to the lengthwise direction of said substrate 1 by dividing grooves 3 plurally formed in the widthwise direction of said substrate, and a high-resistance oxide 8 is formed in said dividing grooves 3. Because of the invention, it is possible to increase the insulation properties of individually divided mated filament conductors, and to obtain an oxide superconductor that has low AC loss.

  • Patent number: 8409657
    Abstract: A production process of a thick-film tape-shaped RE-type (123) superconductor having a high critical current value. The production process has the steps of providing a composite substrate having Gd2Zr2O7 and CeO2 stacked in that order onto a Hastelloy substrate, coating a raw material solution prepared by dissolving a trifluoroacetate of Y and Ba and a naphthenate of Cu onto the composite substrate, heat treating the coated composite substrate by calcination, then subjecting the calcined assembly to intermediate heat-treatment at a temperature below the temperature of heat-treatment for superconductor production, and then heat treating the assembly in an argon gas atmosphere under conditions of highest heating temperature 760° C., water vapor partial pressure 13.5%, and oxygen partial pressure 0.09% for superconductor production to produce a tape-shaped RE-type (123) superconductor having a YBCO superconducting film having a thickness of more than about 2 ?m.

  • Patent number: 8079473
    Abstract: A medical device holder is comprised of a flexible elongated sheet member, and includes a holding portion configured to hold a three-dimensionally configured part connected of the device. The holding portion is configured to bend back on itself to cover the three-dimensionally configured part. A slit is provided in the sheet member to allow insertion of the distal end portion of the holding portion so that the state in which the holding portion covers the three-dimensionally configured part connected can be maintained. The distal end portion of the holding portion is folded toward the opposite direction from the direction to pull out when retrieving the catheter from the sheet member.

  • Publication number: 20090270263
    Abstract: This invention provides a production process of a tape-shaped superconductor which can realize high Jc and Ic values by virtue of the elimination of the cause of generation of cracks and deterioration of an electrical connectivity in crystal grain boundaries. In producing an Re-base (123) superconductor on a substrate by an MAD process, the use of a raw material solution having a Re:Ba:Cu molar ratio of 1:X:3, wherein X is a Ba molar ratio satisfying X<2 (preferably 1.0?X?1.8, especially 1.3?x?1.7), can realize the production of a thick-film tape-shaped superconductor having a superconductivity of Jc=3.20 MA/cm2 and Ic=525 A/cm (X=1.5).

  • Patent number: 5622309
    Abstract: The disadvantages of conventional carton for packaging cut sheets of paper such as the facts that fingers or finger nails are injured upon opening the carton, tearing requires a large force, the removal of the cut sheets is difficult, the beauty of surroundings is spoiled, movement of the carton is required, and industrial wastes are produced are solved by the present invention. A pair of opening face cut lines such as threaded lines, zipper and the like are formed on two selected faces of the rectangular parellelepiped carton, and a trigger cut line such as a threaded line, zipper and the like is formed on this one face or another face. The trigger cut line is connected to the opening face cut lines. The trigger cut line and the opening face cut lines are torn off after cutting and raising a part of the trigger cut line. The face having the opening face cut lines is used as an opened face.
