  • Publication number: 20140183966
    Abstract: An object of the present invention is to provide an inductive power supply system for an electric operation machine capable of readily increasing an allowable amount of a positional displacement between primary and secondary coils. An inductive power supply system for an electric operation machine having an electric storage device and a power receiver includes a power feeder provided with a pair of primary coils connected in series circuit to generate a magnetic dipole at energization. The power receiver has a secondary coil interlinkable to a magnetic flux generated by the primary coils and at the energization of the primary coils.

  • Patent number: 7728473
    Abstract: A electric rotating machine includes a rotor winding constituting a part of a rotor, a conductor provided in a center portion in a radial direction of a rotor body for supplying electricity to the rotor winding from the outside, a leader drawn from the conductor to an outside diameter side, and a connecting line constructed by stacking a plurality of conductor plates to electrically connect the rotor winding and the leader. The connecting line consists of a radial direction linear portion which is straight in the radial direction on the leader side, and a bending portion which branches into two routes toward opposite directions to each other in a rotor shaft direction from the radial direction linear portion and has a linear portion formed at a part of the bending portion. The linear portion of the bending portion is joined to a bottom surface of the rotor winding.

  • Patent number: 6085818
    Abstract: A material sheet assembly in which a label base attached to a release liner by means of an adhesive is set in roll form is used. In a step in which the material sheet assembly is continuously fed out, the release liner is released by leaving the adhesive on the label base, and the release liner is consecutively taken up. By using a noncontact-type printer, printing is effected on the adhesive surface of the label base separated from the release liner to form a printed label. The printed label is in such a form that the printed surface is disposed between the label base and an adherend. The labels can be attached immediately after they are manufactured, and they can be stored or transported by being taken up in roll form while an additional release liner is attached to the printed surface side.

  • Patent number: 5343180
    Abstract: There is disclosed a coil structure which can be rapidly energized or excited, and which reduces the generation of heat in a coil container by an eddy current due to a dynamic disturbance such as vibration and a magnetic field fluctuation, thereby suppressing the occurrence a quench. The coil container is constituted by a low-resistivity material, and a high-resistivity portion is provided at at least one portion of the coil container in the direction of the periphery of the coil container. The high-resistivity portion is provided at a position where a vibration displacement is small or a magnetic field fluctuation is small. When the coil structure is to be energized or excited, the eddy current produced in the direction of the periphery of the superconducting-coil container can be reduced at the high-resistivity portion, and when the dynamic disturbance develops, the generation of heat by the eddy current is suppressed by the low-resistivity material.
