摘要： Provided is an insulated oxide superconducting cable conductor having a high critical current and a high critical current density. The insulated oxide superconducting cable conductor comprises an elongated former, a plurality of tape-shaped multifilamentary oxide superconducting wires which are wound on the former at a bending strain factor of not more than 0.5%, and a spirally wound tape-shaped insulating material covering the tape-shaped multifilamentary oxide superconducting wires. The tape-shaped multifilamentary superconducting wires are superposed on the former in layers, whereby stabilizing materials of the superposed superconducting wires are in contact with each other. The tape-shaped insulating material consists essentially of a material which is contracted at a thermal contraction rate of at least three times that of the tape-shaped multifilamentary wires by cooling from a temperature of 298 K to that of 77 K. The tape-shaped insulating material can apply a pressure to the superposed multifilamentary superconducting wires toward the former while improving electrical contact between the superposed multifilamentary superconducting wires by cooling in employment. The former can be formed of a flexible tube.

摘要： In a compact wide-angle zoom lens having a two-group configuration composed of positive and negative lens groups, the first lens group is composed of G1A and G1B groups, while a stop is disposed between the G1A and G1B groups, thereby yielding a small lens thickness at its telephoto end and making it compact. The first lens group G1 is composed of G1A group comprising, successively from the object side, a negative lens having a meniscus form with a concave surface directed onto the object side and a positive lens having a meniscus form with a convex surface directed onto the object side, and G1B group having at least one biconvex lens. A shutter (stop) is disposed between the G1A and G1B groups, thereby allowing the first and second lens groups to be disposed close to each other at the telephoto end. Further, the zoom lens is set so as to satisfy the following conditional expressions: −0.6
