    • In order to provide a flexible oxide superconducting cable conductor which is reduced in ac loss, tape-shaped multifilamentary superconducting wires covered with a stabilizing metal are spirally wound on a flexible former. Each of the multifilamentary superconducting wires has a plurality of filaments. The filament contains an oxide superconductor. The superconducting wires are preferably wound on the former at a bending strain of not more than 0.3 %. In winding on the former, a prescribed number of tape-shaped multifilamentary superconducting wires are wound on a core member in a side-by-side manner, to form a first layer. Then, an insulating layer is provided on the first layer. This insulating layer can be formed by an insulating tape. A prescribed number of tape-shaped superconducting multifilamentary wires are wound on the insulating layer in a side-by-side manner, to form a second layer. The insulating layer is adapted to reduce ac loss of the conductors. When the former is made of a metal, it is more preferable to provide an insulating layer between the former and the multifilamentary superconducting wires.
    • 为了提供减少交流损耗的柔性氧化物超导电缆导体,用稳定金属覆盖的带状多丝超导线被螺旋缠绕在柔性成形器上。 每根多丝超导线具有多根长丝。 灯丝包含氧化物超导体。 超导线优选以不大于0.3%的弯曲应变缠绕在前者上。 在卷绕在前者上时,规定数量的带状复丝超导线以并列方式卷绕在芯部件上,形成第一层。 然后,在第一层上设置绝缘层。 该绝缘层可以由绝缘带形成。 规定数量的带状超导复丝线并排缠绕在绝缘层上,形成第二层。 绝缘层适于减少导体的交流损耗。 当前者由金属制成时,更优选在前者和多丝超导线之间设置绝缘层。

    • An apparatus for manufacturing an oxide superconducting film employing laser ablation method having a thin film forming chamber having a laser-transparent laser entrance window, a target being provided in the thin film forming chamber and containing components of an oxide superconductor, a laser beam source for irradiating the target with a laser beam from the exterior of the thin film forming chamber through the laser entrance window, and a controller for controlling power of the laser beam which is applied to the target for preventing the power of the laser beam, being applied to the target, from reduction by contamination of the entrance window caused by scattered particles. According to the present invention, it is possible to form an oxide superconducting film having high and uniform characteristics even if a long time is required for film formation, thereby attaining a remarkable effect in improvement of superconductivity of a large area oxide superconducting film.

    • Diclosed are a fluid mixing element in which at least one helical shaft provided with at least one helical groove on an outer peripheral wall thereof throughtout its length is inserted in a cylindrical passage tube provided with at least one helical groove on an inner peripheral wall thereof throughout its length.According to the mixing element of the present invention, the fluid supplied into the mixing element flows partly along the helical groove formed in the passage tube and partly along the helical groove formed on the helical shaft to produce the turbulent mixing of the fluid in the mixing element. When the fluid flows through the helical grooves formed in the passage tube and on the helical shaft of the mixing element, the phase transfer is also carried out at planes perpendicular to the flow direction by inertia of the fluid. Accordingly, the fluid in contact with the helical grooves and the fluid out of contact therewith are replaced with each other in series. The mixing is further effected by division of the fluid in series at each of many contact portions of the passage tube and the helical shaft.As a result, the fluid mixing efficiency can be improved. The number of the mixing elements is therefore reduciable, when the plural mixing elements are connected to each other to form the mixer, and in addition, the time required for mixing in the mixer is also reducible.
    • 密闭式是一种流体混合元件,其中至少一个螺旋轴在其外周壁上至少有一个螺旋槽穿过其长度被插入到一个圆柱形通道管中,圆柱形通道管在其内周壁上设有至少一个螺旋槽 它的长度。 根据本发明的混合元件,供给到混合元件中的流体部分地沿着形成在通道管中的螺旋槽流动,部分地沿着形成在螺旋轴上的螺旋槽流动,以在混合中产生紊流混合 元件。 当流体流过形成在通道管中的螺旋槽和混合元件的螺旋轴时,相位转移也通过流体的惯性在与流动方向垂直的平面处进行。 因此,与螺旋槽接触的流体和与其不接触的流体被相互替换。 进一步通过在通道管和螺旋轴的许多接触部分中的每一个处分离流体来进行混合。 结果,可以提高流体混合效率。 因此,当多个混合元件彼此连接以形成混合器时,可以减少混合元件的数量,此外,混合器中混合所需的时间也可以减少。
