    摘要： A method and apparatus for controlling an induction motor, in which an AC power source is connected to the induction motor through a switch and a frequency converter, and the motor speed is controlled by controlling the output frequency and output voltage of the frequency converter. In the starting operation, the induction motor in a free-running state is supplied with an initial voltage in a given frequency which is expected to make the absolute value of the motor current minimum or near minimum, and then the supply voltage is increased gradually from the initial voltage with its frequency being retained at the given voltage. When the output frequency of the frequency converter reaches a predetermined value, the output frequency and voltage thereof are increased gradually with the ratio therebetween being maintained at a given value.

    摘要： A power inverter including a converter unit for rectifying AC power into DC power, an inverter for inverting the DC power into AC power for driving a load apparatus, and a protection apparatus for protecting the load apparatus from being overloaded. The load protecting apparatus comprises current detecting means for detecting a current supplied to the inverter unit from the converter unit, a memory for storing a thermally limited operation time characteristic determined in consideration of cooling effect proper to the load apparatus, and an abnormality detecting circuit for producing an abnormality signal to stop the operation of the inverter unit when an accumulated value calculated on the basis of the current value detected by the current detector at a predetermined sampling interval exceeds the characteristic value previously stored in the memory. The load apparatus can be positively protected from overload notwithstanding variations in the output voltage and the output frequency of the power inverter.

    摘要： In a clean unit which has a dust filter with a blowing power source on the upper surface of a working chamber and which can maintain a clean environment, an external gas flow passage is directly connected or connected through a partition wall, through which dust particles cannot pass but gas molecules can pass, to a feedback gas flow passage for connecting air-tightly a ventilation hole formed in the wall of the working chamber and the inlet of the dust filter to each other. On both sides of the partition wall, the flow velocity vector of a gas flowing in the feedback gas flow passage is made to be equal to the flow velocity vector of the gas flowing in an external gas flow passage.
