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： Disposed in a magnetic gap of a magnetic core, a magnetically biasing permanent magnet is a bond magnet comprising rare-earth magnetic powder and a binder resin. The rare-earth magnetic powder has an intrinsic coercive force of 5 kOe or more, a Curie temperature of 300° C. or more, and an average particle size of 2.0-50 &mgr;m. The rare-earth magnetic power has a surface coated with a metallic layer containing an oxidation-resistant metal. In order to enable a surface-mount to reflow, the rare-earth magnetic powder may have the intrinsic coercive force of 10 kOe or more, the Curie temperature of 500° C. and the average particle size of 2.5-50 &mgr;m. In addition, to prevent specific resistance from degrading, the metallic layer desirably may be coated with a glass layer consisting of low-melting glass having a softening point less than a melting point of the oxidation-resistant metal.

摘要： A viscous material (4) is obtained by mixing an alloy magnetic powder, magnetized in advance, with a resin. The viscous material (4) thus obtained is applied to an upper surface of a center magnetic leg of an E-shaped core (2). A coil (3) and an I-shaped core are coupled to the E-shaped core (2). An orientation magnetic field is applied by a permanent magnet (5) while the resin is hardened. As a consequence, a bond magnet is obtained which is formed in tight contact with both of a pair of surfaces defining a magnetic gap between the E-shaped core (2) and the I-shaped core.
