    摘要: The invention is to establish means of producing easily and at low cost “a coupled body of superconducting magnets”, comprised of multi-pole bulk superconducting magnets lined up such that the polarities thereof alternately vary so as to cause a magnetic field gradient to occur. The magnetizing method for producing a coupled body comprised of multi-pole bulk superconducting magnets with respective polarities varying comprises the steps of coupling adjacent members for bulk superconducting magnets of a plurality of members for bulk superconducting magnets with each other in such a way as to be freely superposable, foldable, and unfoldable, superposing all the members for the bulk superconducting magnets on top of one after another, and applying a magnetizing process thereto in as superposed state, and unfolding alternately and juxtaposing the respective bulk superconducting magnets as superposed after the magnetizing process as shown in FIG. 1(A) to FIG. 1(D).

    摘要: Particles contained in a suspension are separated in accordance with their magnetic susceptibility and based on the variation in flow velocity of suspension. In order to achieve this magnetic separation, a pair of wall plates having at least one flat surface in which a plurality of ferromagnetic narrow wires are buried in parallel are positioned in parallel to each other with a small distance therebetween so that the flat surfaces are opposed to each other to form a channel. The suspension flows in a laminar state with different flow velocities through the channel in the longitudinal direction of the ferromagnetic wires. A magnetic field is externally applied to the channel in the direction perpendicular both to the flow direction and the wall plates. Particles are separated in accordance with their magnetic susceptibility and based on variation in flow velocity which interacts with the magnetic susceptibility.

    摘要: A primary coil assembly for a superconducting linear induction motor is provided which is arranged opposite to a secondary conductor for exerting a relative thrust on the secondary conductor when energized. The primary coil assembly comprises a plurality of coil units, each including a nonmagnetic and nonconductive bobbin, an alternating-current superconducting wire wound around the bobbin, and nonmagnetic and nonconductive spacers interposed between adjacent turns of the superconducting wire being adjacent to each other in an outward direction with respect to the axis of the bobbin or adjacent to each other in the width direction of the bobbin, for providing a clearance therebetween. The coil units have substantially identical structure and shape and are spaced at a predetermined distance from each other.

    摘要: There is provided a superconducting strand for alternating current which is formed by stranding 13 or more superconducting wires having a diameter smaller than that of a non-magnetic core member in a single-layered form on the outer peripheral surface of the core member and which can efficiently remove heat caused by AC loss, avoid a quenching phenomenon and stably maintain the superconducting state. Preferably, an electrically insulataive braided layer formed of polyester fiber is interposed between the core member and the stranded superconducting wires and stable insulation can be maintained therebetween, thereby preventing flow of coupling current caused by defective insulation and suppressing partial heat generation. The superconducting wire contains a large number of NbTi superconducting filaments and a non-magnetic stainless steel wire can be preferably used for the core member.

    摘要: In a servo type magnetic head drive control device, a moving velocity of a magnetic head is controlled on the basis of an error between an actual moving velocity value of the magnetic head generated using servo data and a target velocity value set in accordance with a moving distance to a target position. When the magnetic head is moved to a predetermined position, transient control is performing by using finite time settling control on the basis of position information and velocity information of the magnetic head, and normal tracking control or tracking control using the finite time settling control is performed to form positioning control of the magnetic head. Also a difference between the head position and the position of the head generated from a model is determined and used to control head movement.
