A phase difference signal is amplified 2 and thereby an output pulse frequency of a voltage-frequency converter 2 is controlled. The output pulse frequency is counted 4 and a two-phase alternating-current generator 20 generating a second two-phase alternating-current input signal e1s.e1R operates in accordance with a count value theta1. In other words, ROM 5a outputs e1R = cos theta1. Besides, an alpha setting unit 12 sets an interphase phase difference alpha of a first two-phase alternating-current input signal eR.eS and the count value theta1 is given to ROM 5b as theta1 - alpha by subtractor 13. The ROM 5b, wherein the same data as in the ROM 5a are written, outputs e1s = cos (theta1 - alpha). A multiphase alternating-current signal is used as it is as an input signal according to this constitution, and thus a change in the frequency of the input and a change in phase thereof can be followed quickly.

Filed: 1986-12-19
Abstract: PURPOSE:To construct a magnetic shield by directly mounting many divided sheetlike superconductors on the outside of a liquid helium vessel containing a superconducting magnet to suppress generation of an eddy current. CONSTITUTION:A superconducting coil 1 is contained in a liquid helium vessel 2 to be dipped in liquid helium 3. Many divided superconducting sheets 4 are so mounted directly on the outside as to cover the vessel. A magnetic field generated from the coil 1 arrives at the sheets 4, but is not leaked to the outside by means of superconducting diamagnetic effect. Accordingly, a large superconducting sheet is not required, superconducting sheets which can be manufactured by the present technique are used, divided, and many sheets are used to suppress an eddy current. Further, since they are directly mounted on the vessel, a supporting structure is not newly necessary. Since the sheets are held at cryogenic temperature by thermal conduction, a refrigerant tank, etc., is not required.

IPC: G11B7/125
Filed: 1988-11-29
Abstract: PURPOSE:To attain reproducing operation or confirming and reproducing operation with fixed reproducing power by controlling a preceding beam in correspondence to the detecting output of a front photodetector at the time of reproducing and controlling a following beam correspondent with a value, for which the detecting output of a rear photodetector is subtracted from the detecting output of the front photodetector at the time of recording or erasing. CONSTITUTION:At the time of reproducing, the reproducing operation is executed only by a preceding beam A. Then, the detecting output of a front photodetector 14 is regarded only for the single preceding beam A and the optical intensity of the preceding beam A is controlled in correspondence to the detecting output of the front photodetector 14. On the other hand, at the time of recording or erasing, in which two beams are simultaneously turned on, the two beams are simultaneously received in the front photodetector 14. Accordingly, not only a following beam B component is generated but the detecting output of the single preceding beam is generated in a rear photodetector 17. Then, the subtracted value of both outputs is obtained and defined as the detecting output corresponding to only the following beam B component and the optical intensity of the following beam B is controlled. Thus, the stable reproducing operation and confirming and reproducing operation can be executed.
