20110291779 | CONDUCTION COOLING SUPERCONDUCTING MAGNET DEVICE - A superconducting coil is accommodated in a vacuum chamber. A radiation shield is arranged in the vacuum chamber with a prescribed space from the vacuum chamber to surround a periphery of the superconducting coil. A refrigerator cools the superconducting coil and the radiation shield by conduction. A provided member at least partly lies between the vacuum chamber and the radiation shield, through which heat is conducted from the vacuum chamber to the radiation shield. A cooling pipe has opposite end portions drawn out of the vacuum chamber and an intermediate portion in contact with the superconducting coil, the radiation shield, and the provided member. The provided member dissipates heat into a coolant flowing through the cooling pipe, to reduce the heat conducted to the radiation shield. | 12-01-2011 |

20150052936 | SEALED COMPRESSOR AND VAPOR COMPRESSION REFRIGERATION CYCLE APPARATUS INCLUDING THE SEALED COMPRESSOR - A sealed compressor includes a centrifugal impeller above a rotor to synchronously rotate. A refrigerant rises through a rotor air hole, flows in an upper space, and flows out from a discharge pipe. The centrifugal impeller includes an oil separation plate on the rotor, and plural vanes standing on the oil separation plate, and forms inter-vane flow passages between adjacent vanes, and a vane inner flow passage that guides refrigerant from the rotor air hole to inner entrances of the inter-vane flow passages. Outer exits of the inter-vane flow passages are disposed along an entire circumference, and refrigerant increased in pressure while passing through the inter-vane flow passages flows out from the outer exits to the upper space. The oil separation plate closes a short-circuit passage through which the refrigerant directly flows from the vane inner flow passages to the discharge pipe without passing through the inter-vane flow passages. | 02-26-2015 |
