  • OPERATING CONDITION DECISION DEVICE, OPERATION ASSISTANCE DEVICE, CONTROL DEVICE, AND OPERATING CONDITION DECISION METHOD FOR ROTATING MACHINE
    Publication number: 20240142346
    Abstract: An AE signal is acquired from an AE sensor disposed on a fixed part of the rotating machine, and the presence or absence of rubbing in the rotating machine is determined, based on the AE signal. As a result, if the rubbing is determined to be present, a rubbing suppression operating condition imposed on control of the rotating machine is decided to suppress the rubbing.

  • POWER-GENERATING SYSTEM
    Publication number: 20150001989
    Abstract: A power-generating system includes a heat source which is able to produce temporal temperature variation; a first device which is able to produce temporal temperature variation based on the temperature change of the heat source and in which polarization occurs; a second device for taking out a net generating power from the first device; a detection unit that detects the temperature of the first device; an electric field application unit that applies an electric field to the first device; and a control unit for activating the electric field application unit when the temperature detected by the detection unit is the Curie temperature of the first device or higher.

  • POWER-GENERATING SYSTEM
    Publication number: 20140217852
    Abstract: A power-generating system includes a heat source which is able to produce temporal temperature variation; a first device which is able to produce temporal temperature variation so as to include at least partially a temperature range of ?20° C. relative to the Curie temperature to +10° C. relative to the Curie temperature based on the temperature change of the heat source, and in which polarization occurs; and a second device for taking out a net generating power from the first device.
