A superconductive cable including: a former; one or more superconductive conductor layers provided outside the former; an insulating layer configured to surround the superconductive conductor layers; and one or more superconductive shield layers provided on an exterior of the insulating layer. The superconductive conductor layers and the superconductive shield layers are formed of superconductive wire rods, and each superconductive wire rod includes a metal substrate layer and a plurality of superconducting layers deposited on the metal substrate layer using a superconductive material. In the superconductive wire rods of an outermost superconductive conductor layer among the superconductive conductor layers and an innermost superconductive shield layer among the superconductive shield layers, each of the metal substrate layers and the superconducting layers are disposed in opposite directions.

Superconductive cable

The present invention relates to a cryogenic cooling apparatus capable of stably maintaining a cryogenic condition by repairing or exchanging a sensor such as a temperature sensor of the cryogenic cooling apparatus without releasing vacuum states of the cryogenic cooling apparatus and a system connected thereto, when the sensor needs to be repaired or exchanged.

A method of determining, and an apparatus to determine, a track zero position of a disc in a disc drive, the method including seeking, sequentially, in units of predetermined numbers of tracks, outwardly from a designed track zero position to a predetermined critical track position of the disc; determining whether track following is performed normally during the seeking; and determining an actual track zero position by shifting the designed track zero position inward by a predetermined number of tracks in response to the track following not performing normally, and determining the actual track zero position to be the designed track position in response to the track following performing normally.

Method of determining and applying adaptive track zero position and disc drive using the same

A method of managing defects in a hard disk drive, and more particularly, a method of managing defects in a hard disk drive in a case where a position of defects on a disk is known in advance. A data zone is allocated to predetermined tracks around tracks including defects known in advance, and the data zone is managed for defects.

Method of managing defects in hard disk drive, recording media therefor and hard disk drive therefor

A discharge valve device of a rotary compressor comprises a discharge passage formed in the wall of a cylinder for connecting to a compression chamber, a discharge valve for blocking/opening the discharge passage depending upon the gas pressure in the chamber, and a spring for restricting the movement of the discharge valve. The discharge valve moves along a passage wall in contact therewith during travel between its blocking/opening positions.
