    摘要： A dielectric strength test method of a superconducting cable that can evaluate the insulation characteristic of a superconducting cable in a state in which a refrigerant is filled without filling a refrigerant is provided.A tested superconducting cable is filled with gas in place of a refrigerant and a regular dielectric strength test is conducted at room temperature. Preferably, a preliminary dielectric strength test is conducted prior to the regular dielectric strength test. In the preliminary dielectric strength test, a first reference superconducting cable filled with a refrigerant at a predetermined pressure and a second reference superconducting cable filled with gas in place of a refrigerant at a predetermined pressure are provided. The preliminary dielectric strength test is conducted for the first reference superconducting cable at refrigerant temperature and the second reference superconducting cable at room temperature to find the correlation between the dielectric strength characteristics of the cables. At the time, the test voltage is determined based on the dielectric strength characteristic of the second reference superconducting cable. The regular dielectric strength test is conducted at the test voltage.

    摘要： A cooling device for a semiconductor component which increases mechanical strength thereof and reduces a pressure loss of coolant. Plate members constituting the cooling device are formed with flow passages such as coolant supply and discharge openings, grooves divided by ridges, and through portions separated by projections or partitions. The ridges, projections, and partitions are joined to a adjacent plate member to increase the joining strength, which is further increased by forming the ridges, projections, and partitions of different plate members at the same positions. In the case of laminating the plate members having surfaces formed with solder layers, a number of minute vacant spaces are formed in those joining faces of the plate members which are not formed with passages, etc., and solder filets are formed over the entire joining faces to increase the joining strength. The grooves and through portions can be formed by chemical etching together with outer shapes of the plate members. A plurality of plate members can be fabricated from a single sheet material at a time.

    摘要： A solid DC cable is made of a conductor having multilayered insulating layer around the outer circumference of the conductor. The insulating layer has a layering configuration selected from one of the following arrangements: (i) a main insulating layer and a low resistance tape layer, where the low-resistance tape layer contains carbon paper that has a volume resistivity which is smaller than that of the main insulating layer; (ii) a main insulating layer containing kraft paper, and a low-resistance insulating layer containing a low resistance kraft paper having a resistivity smaller than the kraft paper of the main insulating layer; (iii) a main insulating layer containing a composite tape, where the tape is contains a laminate of a low-loss plastic film and kraft paper, and a low-resistance insulating layer containing kraft paper having a resistivity lower than the main insulating layer; or (iv) a low-resistance tape layer containing carbon paper described in (i), a low-resistance insulating layer containing the low-resistance kraft paper described in (ii) and a main insulating layer. The low-resistance insulating layer or the low-resistance tape layer is positioned above the conductor in a region where the pressure of the insulating oil becomes negative when a voltage load is cut off.

    摘要： The air inside a housing containing heat generating parts is forced by an inside air fan to flow in a heat exchanger case through an inside air inlet, flow partially upward and partially downward in an inside air passage while being cooled by inner fins, between the inner fins, installed in the inside air passage, that form a heat exchanger heat sink, and discharge from the inside air passage through an upper, first inside air outlet and a lower, second inside air outlet. The air discharged through the two inside air outlets flows over the surfaces of the heat generating parts in the housing, taking heat from them.

    摘要： A joint for a superconducting cable joints superconducting cables with one another. The superconducting cable comprises a former, superconducting conductor, and insulating layer. The construction of the joint comprises the following steps: preparing a jointing ferrule for jointing the formers, sliding the ferrule over the end portions of the formers to be jointed, butting the end faces of the formers against each other in the jointing ferrule, compressing the jointing ferrule to joint the formers such that the compressed ferrule has a diameter equal to that of the former, butting the end faces of the superconducting conductors against each other at the outside of the compressed ferrule, and jointing the superconducting conductors with each other such that the jointed superconducting conductors have a diameter equal to that of the superconducting conductor of the superconducting cable. The foregoing steps can decrease the size of the joint.
