摘要： A cable and cable system is provided having a conductor and an insulation layer on an outer circumference of a conductor. The insulation layer is impregnated with a medium-viscosity insulating oil that has a viscosity of 10 centistokes (cst) to less than 500 cst at 60° C. The insulation layer includes an insulating tape that may be one or a combination of composite tape having a polyolefin resin film laminated with a kraft paper on both its sides and an insulating tape including a polyolefin resin film. The cable includes a metal sheath provided on an outer circumference of the insulation layer, and a reinforcing layer formed on an outer circumference of the metal sheath. The reinforcing layer reinforces the metal sheath by absorbing hoop stress exerted on the metal sheath. The cable system includes a submarine-portion cable and a land-portion cable, an oil stop joint box, and an oil feeding tank. The oil stop joint box connects the submarine-portion cable to the land-portion cable, and the oil feeding tank is connected to the land-portion cable which feeds the medium-viscosity insulating oil to the land-portion cable.

摘要： A cooling device suitable for cooling a laser diode bar constituting a surface illuminating device as a light source for exciting a laser medium of a solid-state laser oscillator of high power. The cooling device is capable of flowing coolant at sufficient flow rate by reducing the pressure loss in the flow passage of the coolant in the device, to realize a light source device of small thickness with high cooling capability and high reliability. The cooling device comprises a first plate member, one or more second plate member and a third plate member to be joined together to form a laminated body. The second plate member has grooved paths formed on both surfaces thereof and having depths greater than a half of thickness of the plate member, and also opened paths for communicating grooved paths formed on the first plate member and the third plate member. The pressure loss in the flow passage of coolant is reduced by increasing a sectional area of the flow passage by the grooved paths and the opened path of the second plate member without lowering mechanical strength of the device and without increasing a manufacturing cost of the device.

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.

摘要： The method concerns fabricating heat-resistant heavy-duty components of a rbine, e.g. disk, wheel, etc. wherein two or more different kinds of alloys are junctioned, which comprises solidifying the one alloy powder by hot isostatic pressing or extrusion, junctioning and solidifying the solidified alloy with the other alloy powder by hot isostatic pressing or extrusion, and subjecting the alloys thus obtained to superplasticity forging thereby to secure the junction boundary. Ni-base superalloys having different complete solid solution temperatures of gamma prime phase are selected for use in the hub and rim of a turbine disk or the like, the one alloy which is higher in the temperature being disposed for the hub and the other alloy for the rim. The difference in the temperature between both alloys is at least 8.degree. C. Further solution heat treatment is performed at a temperature between the complete solid solution temperatures to adjust crystal grain size. Heat-resistant heavy-duty components of a turbine, e.g. disk, etc. are thus fabricated by superplasticity forging from Ni-base superalloys.
