    • A single crystal pulling device is composed of a cylindrical pulling furnace, a crucible disposed in the pulling furnace in which a single crystal material for a semiconductor is poured, a cylindrical vacuum vessel coaxially disposed around the pulling furnace, and a superconducting magnet composed of a plurality pairs of coils arranged inside the vacuum vessel so as to generate magnetic field. The superconducting coils are arranged on the same horizontal plane of the cylindrical vacuum vessel, and each of the paired superconducting coils includes coils set so as to oppose to each other with respect to a central axis of the cylindrical vacuum vessel so that one coil of one pair of coils and one coil of another pair of coils adjacent to that one pair of coils constitutes a set angle, directing towards the inside of the cylindrical vessel, in a range of 100° to 130°.

    • A digital subscriber line communicating system for communicating between a transmitting side and a receiving side through a communication line, comprising a hyperframe counter for periodically counting a predetermined number of continuous transmitting data symbols constituting a hyperframe synchronized with a timing signal, and a decoder for discriminating, based on the count value of the hyperframe counter, whether a transmitting data symbol belongs to a FEXTR or a NEXTR. A sequencer is provided for initializing the status during an initialization period before starting usual communication. The initialization period includes an activation and acknowledgement sequence, a transceiver training sequence, a channel analysis sequence, and an exchange sequence. According to a single bitmap mode, the initialization is carried out by transmitting modulated symbols through only inside of said sliding window. According to a dual bitmap mode, the initialization except for an S/N measuring sequence in the channel analysis sequence is carried out by transmitting modulated symbols through only inside of said sliding window, and the S/N measuring sequence is carried out by transmitting modulated symbols through both inside and outside of said sliding window.
