Abstract: A rotational shaft seal member which does not cause leakage of powder and which has a slit capable of being enlarged as a result of occurrence of springback. Cylindrical shaft seal member 4b at powder container 1 includes pile 5 including woven/knit pile fabric 7 having cut pile 7b at the inside of cylindrical shaft seal member 4b and pile cylindrical support member 4c; the outside diameter 4e being capable of shrinkage as a result of external pressure, and being capable of enlargement as a result of pressure on the inside diameter 4d.

Abstract: In a control method performed in shifting a plurality of different types of power generators to parallel operation, at least one of output voltage and a voltage drooping characteristic of at least one of the plurality of power generators is changed. In the case where the plurality of different types of power generators are a plurality of synchronous power generators having different voltage drooping characteristics, the voltage drooping characteristic of one power generator having a smaller voltage drooping characteristic among the plurality of power generators to be operated in parallel is changed so as to coincide with the voltage drooping characteristic of the other power generator. At the time of changing the voltage drooping characteristic, the other power generator is controlled so that the output voltage thereof is maintained at a value before start of the parallel operation.

On an inner peripheral surface of the seal portion, a main lip is in slidable contact with an outer peripheral surface of a rotary shaft, and a vacuum space side inclined surface gradually enlarges in diameter from the main lip toward a vacuum space side.
