    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： In order to provide an inductance part having excellent DC superposition characteristic and core-loss, a magnetically biasing magnet, which is disposed in a magnetic gap of a magnetic core, is a bond magnet comprising magnetic powder and plastic resin with the content of the resin being 20% or more on the base of volumetric ratio and which has a specific resistance of 0.1Ω·cm or more. The magnetic powder used is rare-earth magnetic powder having an intrinsic coercive force of 5 kOe or more, Curie point of 300° C. or more, and an average particle size of 2.0–50 μm. A magnetically biasing magnet used in an inductance part that is treated by the reflow soldering method has a resin content of 30% or more and the magnetic powder used therein is Sm—Co magnetic powder having an intrinsic coercive force of 10 kOe or more, Curie point of 500° C. or more, and an average particle size of 2.5–50 μm. A thin magnet having a thickness of 500 μm or less can be realized for a small-sized inductance part.

    摘要： A low-profile magnetic core capable of reducing the thickness of an inductor component is provided. The magnetic core includes at least one gap in a magnetic path, and a permanent magnet is inserted in the gap. The magnetic core has an alternating current magnetic permeability at 20 kHz of 45 or more in a magnetic field of 120 Oe under application of direct current, and has a core loss characteristic of 100 kW/m3 or less under the conditions of 20 kHz and the maximum magnetic flux density of 0.1 T. An inductor component is produced by applying at least one turn of coil to the aforementioned magnetic core.
