摘要： An AC magnetic floating apparatus for floating and conveying a conductive floating body of paramagnetic or nonmagnetic metallic material above a line of AC electromagnets, includes a single-phase AC current source having a first frequency for floating the floating body, a three-phase AC current source having a second frequency for conveying the floating body, an adder for adding AC current from the two current source and a supply circuit for supplying the added Ac currents to the line of AC electromagnets. The floating body can be stopped at a desired position exactly with efficient conveyance.

摘要： An alternating current magnetic levitation transport system transporting a floating body made of conductive paramagnetic or nonmagnetic metallic material being levitated over alternating current electromagnets by making use of repulsion of an alternating electromagnetic field, comprises a tubular passage provided over the alternating current electromagnets which are spatially cut off from the outside wherein the floating body is levitated and transported. A cooling system made of a conjoined body of a thermoelectric cooling thermomodule and a liquid-cooled heat exchanger is provided in the transport system in contact with said tubular passage. This system can be favorably used in a clean environment where dust generation has to be avoided and the system can thereby provide more efficient transportation.

摘要： The present invention relates to a magnetic levitating transport system for transporting a levitating body composed of conductive paramagnetic or non-magnetic metal above electromagnet arrays by generating an alternating magnetic field in a pair of parallel electromagnet arrays.The dimensions of the levitating body are expressed in relation to dimensions of the electromagnet arrays, as well as, other dimensions of the levitating body. The specific symmetrical shape, having a flat underside, allows the levitating body to manoeuvre a curve having a large curvature. In addition, perpendicular direction changes are effected using transportation passages.

摘要： A control system for a magnetic type bearing is fed back a signal from a position sensor with respect to a floating member to effect control such as phase compensation so that the magnetic type bearing is actively employed. In order to change unstabilizing force produced by the magnetic type bearing in a specified frequency range to stabilizing force, a first signal obtained by causing the signal from the position sensor to pass through a first filter having a cut-off frequency range corresponding to a predetermined frequency range in which stabilization is to be attained and a second signal obtained by causing a signal having an opposite polarity to that of the signal from the position sensor to pass through a second filter having a passing frequency range which is substantially identical with the predetermined frequency range are added to each other and the addition signal is fed back to an electromagnet.

摘要： In a sealing device for a rotary machine of the type that an annular groove is provided in an inner circumferential surface of a through-hole of a stationary member through which a rotary body supported rotatably by a bearing device extends, gap spaces between the rotary body and the both side portions of the stationary member on the opposite sides of the annular groove are sealed by seal rings, and a seal fluid feed hole for feeding a sealing fluid into the annular groove is provided in the stationary member; improvements are made in that a vibration suppressing movable ring is accommodated within the annular groove, the movable ring is mounted to the stationary member so as to be movable only in a radial direction so that an outside annular gap clearance may be formed between an outer circumferential surface of the movable ring and an inner circumferential surface of the annular groove and also an inside annular gap clearance may be formed between an inner circumferential surface of an inner hole of the movable ring and an outer circumferential surface of the rotary body which extends through the inner hole, the inside gap clearance is divided into a plurality of arcuate gap clearance sections, and the respective arcuate gap clearance sections a formed in a wedge-like shape that is gradually narrowed towards the downstream side in the direction of rotation of the rotary body.
