摘要： A rotating table provided with a determined gap Db and serving as a rotating body is rotatably mounted on a fixed base. Seal-member accommodating spaces serving as annular grooves are partitioned and formed in a fixed surface. Annular seal members are disposed in the seal-member accommodating spaces. When a vacuum is supplied to a communication passage, the absorbed seal members contact with the fixed surface and a rotated surface to seal gaps therebetween. When a positive pressure is supplied to the communication passage, the seal members are relocated in the seal-member accommodating spaces. The seal-member accommodating space has a taper portion, thereby preventing the seal members from biting. While the rotating table is being rotatably driven, no vacuum is supplied to the communication passage.

摘要： An inductor component contains a drum magnetic core made of a magnetic material having a structure including integrated flanges at both ends of a columnar material, a coil wound around the columnar material in the drum magnetic core and placed between the flanges, and a permanent magnet placed in the neighborhood of the drum magnetic core with the coil wound around. This inductor component contains a sleeve core fitted to the outside of the drum magnetic core. The permanent magnet is placed in at least one gap in a closed magnetic circuit formed with the drum magnetic core and the sleeve core in order to apply a direct-current magnetic field in the direction opposite to the direction of a magnetic field generated by a magnetomotive force due to the coil.
