摘要： OPC areas are used for adjusting recording parameters (power and strategy). In an optical disc including two recording layers, the recording power for one recording layer is likely to be influenced by a transmittance variance or the like provided by the recording state of the other recording layer (either already recorded or unrecorded). In addition, recording is performed while changing the power. For these reasons, the OPC areas are located so as not to be at the same radial positions among the recording layers. However, as the number of recording layers is increased, the area size for securing the OPC areas is increased, which may undesirably lead to an increase of the lead-in zone or the lead-out zone (decrease of the user data zone) and a decrease of the OPC area size in each recording layer (decrease of the number of times of usage by the user). According to the present invention, an area for power calibration in which recording is performed while changing the power and so which is significantly influenced by the transmittance balance, is separated from an area for strategy calibration or the like in which recording is performed at a fixed power suitable to the disc and so which is unlikely to be influenced by the transmittance balance. Only power calibration areas are located at different radial positions among different recording layers so as not be influenced by the recording state of the other recording layers, and the strategy calibration areas are located so as to include the same radial position among different recording layers.

摘要： A multiphase superconducting cable connection structure includes a connection box accommodating three conductor connects connecting a superconductor of a cable core of each phase extracted from a pair of 3-phase superconducting cables, a solid insulation member fixed to an outer circumference of each conductor connect, and a metal flange fixing the solid insulation member to the connection box. By fixing the metal flange to the connection box (a refrigerant vessel), the conductor connect can be positioned and the conductor connector's movement caused as the cable core thermally contracts can be reduced. The structure can help to position the conductor connect in the connection box and reliably hold it at a prescribed position.

摘要： A first flange and a second flange are superposed and fastened with a bolt and a nut in a fastening operation, to implement a fastening structure used at temperature lower than atmospheric temperature for the fastening operation. Assuming that the first flange has a thickness L1 and a coefficient of linear expansion α1, the second flange has a thickness L2 and a coefficient of linear expansion α2, superposed first flange and second flange have a thickness L, and the bolt has a coefficient of linear expansion α, a relation of L·α≧L1·α1+L2·α2 is satisfied, i.e. heat shrinkage of the bolt is not smaller than the total heat shrinkage of the first and second flanges. Thus, impairment of sealing property due to heat shrinkage is avoided at a flange junction used at low temperature.
