The present invention provides a terminal structure of a superconducting cable including a cable core having a superconducting shield layer and an electrical insulation layer. The superconducting shield layer has a radially outer portion provided with by a connection electrode and the superconducting shield layer and the connection electrode are connected together with a low melting solder. The connection electrode has a ground wire connected thereto to ground the superconducting shield layer. For a multiphase cable including a plurality of cable cores, connection electrodes are linked by a conductive coupling member to short circuit superconducting shield layers. The superconducting shield layer can be grounded without impaired insulating property of the electrical insulation layer.

A phase split structure of a superconducting cable includes three cable cores each having a shield layer provided around a superconductor, a splitter box housing the three cable cores extending from an assembly portion where the three cable cores are assembled into the cable, in a state in which the cable cores are spaced apart from each other, and a shield connecting portion connecting respective shield layers of the cable cores to each other within the splitter box. The shield connecting portion allows the cable cores to have their respective shield layers connected together with low resistance and each shield layer can pass a current substantially equal in magnitude to that which each superconductor passes. Thus in each shield layer a magnetic field can be formed having a level that can cancel a magnetic field generated from each superconductor. The structure can thus effectively prevent a large magnetic field external to the cable core.

An interface circuit includes an interface communication section for performing communication with an upstream device; a system interface communication section for performing communication with a system controller; and an interface control section for controlling these sections. The interface control section includes a section for executing first reset processing; a section for requesting the system interface communication section to request the system controller to permit execution of second reset processing different from the first reset processing; a section for requesting the system interface communication section to receive a report of the permission of the execution of the second reset processing from the system controller; a section for executing the second reset processing in accordance with the report of the permission of the execution of the second reset processing; and a section for requesting the interface communication section to report completion of the second reset processing to the upstream device.
摘要:
To provide a cooling method of a superconducting cable line wherein moistures contained in the cable in the superconducting cable line after laid is removed before cooling, so that solidification of the moistures can be prevented from clogging of piping including a coolant flow channel and a return pipe. There is provided an inert gas generating vessel so that before the coolant is flown into the superconducting cable line 15, the inert gas is blown into the cable line from an inflow pipe 23 connected with a supply pipe 19′ and is discharged from a discharge pipe 22 together with the gas. The inert gas is preheated by a heater 3 before feeding it into the cable line. The discharge pipe 22 connected with a discharge side B of the return pipe 19 is provided with a moisture measuring instrument 20 to measure a moisture content of the discharged gas.

A stage constituent circuit of a display device drive circuit includes a first-node to a third-node, a thin-film transistor that changes a potential of a scanning signal toward a VDD potential when a potential of the first-node is in a HIGH level, a thin-film transistor that changes a potential of a different stage control signal toward a potential of a clock when a potential of the second-node is in the HIGH level, a capacitor between the first-node and the second-node, and a capacitor between the second-node and the third-node. The potential of the first-node is raised on the basis of a different stage control signal output from the stage constituent circuit in the different stage, and then the potential of the second-node and a potential of the third-node are sequentially raised. Herein, an amplitude of the clock is set to be smaller than an amplitude of the scanning signal.

A monolithic gate driver capable of operating with a relatively small number of circuit elements is realized. A stage constituent circuit constituting each stage of a shift register includes two output terminals connected to scanning signal lines, two thin-film transistors each having a drain terminal to which an output control clock signal is supplied and a source terminal connected to the output terminal, a first-node connected to the two thin-film transistors in common, a first-node control circuit, and an input terminal for receiving a set signal. In this configuration, the first-node changes from an OFF level to an ON level based on the set signal. Further, the first-node control circuit changes the first-node from the ON level to the OFF level.

There is provided a method for separating an arsenic mineral from a copper-bearing material containing arsenic, such as a copper ore or a copper concentrate, to obtain a copper concentrate with low arsenic grade.The method for separating an arsenic mineral from a copper-bearing material by flotation includes adding a flotation agent containing a depressant, a frother, and a collector to a slurry composed of a copper-bearing material containing arsenic, and blowing air into the slurry to float a copper concentrate, wherein the depressant is sodium thiosulfate. The sodium thiosulfate is preferably added in an amount of 10 kg or more and 200 kg or less in terms of sodium thiosulfate pentahydrate per ton of copper-bearing material to be subjected to flotation. Further, the oxidation-reduction potential of the slurry to be subjected to flotation, as measured against a silver/silver chloride reference electrode, is preferably −10 mV or more and 50 mV or less.
