摘要： A method for detecting degradation of resin film detects whether a resin coated rope having a circumferential portion coated with resin film has the resin film degraded. The method for detecting degradation of resin film includes: winding a wire on a circumferential portion of the resin coated rope; applying tension to the wire to compress the resin film in a radial direction of the resin coated rope; and comparing a first relationship with a second relationship to determine how the resin film is degraded, the first relationship indicating a relationship between the tension of the wire and how much amount the resin film has compressed, as obtained in the applying, the second relationship indicating a relationship between the tension of the wire and how much amount the resin film has compressed, as predetermined as a reference.

摘要： A power conversion control device includes a modulation-wave generating unit generating a modulation wave based on output voltage phase angle command and modulation factor, a carrier-wave generating unit that, in a case of non-overmodulation state, generates a triangular wave or saw-tooth wave as the carrier wave, and, in a case of overmodulation state, generates, as the carrier wave, a signal fixed to −1 in a first section that is a predetermined range centering on timing corresponding to a peak position of the modulation wave, generates, as the carrier wave, a signal fixed to +1 in a second section obtained by shifting the first section by a half cycle of the modulation wave, and generates, as the carrier wave, a triangular wave or saw-tooth wave in remaining third section, and a comparing unit that compares the carrier wave and the modulation wave and generates a switching signal.
