    • A variable-delivery refrigerant compressor wherein the delivery of a compressed refrigerant is adjustable by an actuator which is movable with a discharge pressure of the compressor between a first position at which plural discharge valves corresponding to compression chambers are rendered operative, and a second position at which at least one of the discharge valves is rendered inoperative. A pilot switch valve is disposed in a passage through which the discharge pressure is applied to the actuator. The switch valve controls a supply of refrigerant of the discharge pressure to the actuator such that the actuator is placed in the first position while a suction pressure of the compressor is relatively high, and in the second position while the suction pressure is relatively low.

    • A magnetic characteristics measurement system includes a superconducting quantum interference device which detects a magnetization of a sample located in the vicinity of a superconducting pickup coil and outputs an electrical signal representing the magnetization. A coil is disposed to surround the superconducting pickup coil and is connected to an AC power supply so as to generate an alternating magnetic field. The AC signal output from the superconducting quantum interference device is sampled by use of an A/D converter which is operable in an audio frequency range and outputs a digital signal corresponding to the AC signal. Phase adjustment is performed so as to optimally correct a time shift of the digital signal in relation to a reference voltage signal. The phase-adjusted signal is subjected to Fourier transformation processing so as to detect harmonic components as magnetic characteristics.

    • The present invention provides an automatic power restoring method capable of reliably detecting continuity by the dissolution of a line fault, to restore the optical power, even in a structure including an optical amplification medium on an optical transmission path and an optical communication system using the method. To this end, in an optical communication system to which the automatic power restoring method of the invention is applied, a pilot signal having a low transmission rate, a wavelength of which is set based on loss wavelength characteristics obtained by combining loss wavelength characteristics of an optical fiber used for the optical transmission path and loss wavelength characteristics of the optical amplification medium on the optical transmission path, is transmitted and received between an optical transmitting station and an optical receiving station when a line fault occurs, and a detection of continuity is thus performed. According to the result of the continuity detection, the power state at the occurrence of line fault is automatically restored to the power state at a time of normal operation.
