摘要： A first and a second power roller supported by trunnions are gripped between an input disc and an output disc disposed on an identical rotation axis. The gyration angles of the power rollers are varied by driving the trunnions in a direction perpendicular to the rotation axis by an oil pressure actuator. The oil pressure of the actuator is controlled based on a target gyration angle, and the gyration angle of the first power roller is fed back to the oil pressure control. Vibration of the first power roller due to external disturbance is prevented from affecting the second power roller via oil pressure control by making a force according to a displacement of the first power roller in the direction perpendicular to the rotation axis, act only on the trunnion supporting the first power roller.

摘要： In a continuously variable transmission for use with a vehicle comprising an actuator for continuously varying a speed change ratio, a target speed change ratio is set according to the vehicle running conditions and a real speed change ratio of the transmission is detected. A proportional value which is directly proportional to a difference between the target speed change ratio and real speed change ratio, and an integral value of the difference therebetween, are calculated. When the integral value is not within a preset range, the integral value is corrected to a value within the range, and the actuator is driven based on the sum total of the proportional value and the corrected integral value. In this way, a command exceeding the response capability of the actuator is prevented from being output to the actuator, and overshoot of the speed change ratio is prevented.

摘要： The present invention provides a power device including a converter part (2) for converting an AC voltage to a DC voltage; an inverter part (3) for converting the DC voltage outputted from the converter part (2) to the AC voltage; and a transformer (4) having an inductance forming a series resonance circuit together with an electrostatic capacity of a load (20) to boost the AC voltage outputted from the inverter part (3). In the power device, an inductance (7) is connected to the output part of the inverter part (3) in parallel with the transformer (4). Thus, in a discharge part 6 provided in the load (20), since when a discharge is not generated, a recovery current is not supplied to a circulating current diode in the inverter part (3), or the quantity of the recovery current is reduced, the heat generation of the circulating current diode can be suppressed without increasing the number of elements of the circulating current diode.

摘要： A pressure of a laser gas in an enclosure (7) is detected by a gas pressure sensor (12), and a pressure comparison circuit (13) determines whether the thus-detected pressure is normal or anomalous. An electric current output from an inverter (10) that drives a blower (5) to cause a laser gas to flow back, is detected by a current detection circuit (9). A current comparison circuit (11) determines whether or not the output current is normal or anomalous. A result of a pressure comparison circuit (13) and a result of the current comparison circuit (11) are sent to an AND circuit (15) and performed AND processing. A result of the AND circuit (15), a result of the current detection circuit (9), and a result of the gas pressure sensor (12) are sent to a comparison operation section (17) in a controller (14). A determination is made as to whether or not the blower is anomalous. When the blower is determined to be anomalous, a signal is output to an oscillator and a machine control section (18), to thus stop the oscillator and the machine. Thereby, an anomaly in the blower (5) can be detected regardless of fluctuations in the pressure of the laser gas.
