20100058790ROTARY TYPE ULTRALOW TEMPERATURE REFRIGERANT SUPPLY APPARATUS - The rotary type ultralow temperature refrigerant supply apparatus includes a refrigerant introduction pipe coupled to the super conductive rotor for supplying a liquid-phase ultralow temperature refrigerant cooled by the refrigeration system to the evaporator, a refrigerant withdrawal pipe disposed spaced apart from the refrigerant introduction pipe for withdrawing a gas-phase ultralow temperature refrigerant obtained through the evaporation of the liquid-phase refrigerant by the evaporator and guiding the withdrawn gas-phase ultralow temperature refrigerant to the refrigeration system, and a vacuum housing fixedly disposed outside the refrigerant introduction pipe and the refrigerant withdrawal pipe, the vacuum housing having a vacuum heat insulation space defined inside.03-11-2010
20100060089DEVICE FOR COOLING CURRENT LINES OF SUPERCONDUCTING ROTATING MACHINE - A cooling device for current lines of a superconducting rotating machine, which is capable of removing heat generated from the current lines of the superconducting rotating machine, thereby effectively preventing a superconducting coil from being deformed due to the heat generated from the current lines, is disclosed. The cooling device includes heat conduction members respectively mounted to outer surfaces of the current lines. Each heat conduction member is in contact with an inner peripheral surface of the stator such that the heat conduction member transfers, to the stator, heat generated from a corresponding one of the current lines. The heat conduction member further includes insulators each surrounding a corresponding one of the current lines between a corresponding one of the heat conduction members and a power slip ring arranged in the stator, to thermally insulate the heat generated from the corresponding current line.03-11-2010
20100061869CRYOGENIC FLUID CIRCULATION PUMP - Disclosed is a cryogenic fluid circulation pump that is capable of preventing heat from permeating into a cryogenic fluid by convection during the circulation of the cryogenic fluid by the pump and, at the same time, minimizing the transfer of heat to the cryogenic fluid circulating through a shaft rotating to rotate the pump. The cryogenic fluid circulation pump includes a magnet pump unit mounted in a vacuum chamber having an introduction channel and a discharge channel formed therein to prevent heat from permeating into the cryogenic fluid by convection for rotating by a magnetic force to circulate the cryogenic fluid, when a rotary force from a power source is transmitted to the magnet pump unit.03-11-2010
