  • Patent number: 9887656
    Abstract: A current command value calculating unit (174) calculates current command values for a rotor winding (30) and current command values for a stator winding (20) with respect to a torque command value between a first rotor (28) and a second rotor (18) and a torque command value between a stator (16) and the second rotor (18) based on an evaluation function representing a total copper loss of the rotor winding (30) and the stator winding (20) and using first and second magnetic interference models. The first magnetic interference model represents a relationship of a linkage magnetic flux ?in of the rotor winding (30) with respect to a current Iin in the rotor winding (30) and a current Iout in the stator winding (20). The second magnetic interference model represents a relationship of a linkage magnetic flux ?out of the stator winding (20) with respect to the current Iin, Iout.

  • Patent number: 9619055
    Abstract: In a liquid crystal display panel including a touch panel and a front window, it is possible to reduce the reproduction cost of the touch panel, achieving a high yield in the reproduction of the touch panel. The touch panel and the front window are bonded together by a PET film and a UV curable resin. When air bubbles or other defects are found between the front window and the touch panel, the front window and the touch panel are detached by cutting the UV curable resin by a cutter blade, in order to reproduce the touch panel. The residue of the UV curable resin left on the PET film is removed by detaching the PET film from the touch panel. A tab in which the adhesive is not formed is provided in an end of the PET film, so that the PET film can be easily detached from the touch panel, starting from the tab.

  • Publication number: 20150340936
    Abstract: When sub-field magnets 8a and 8b are not provided, the magnetic fluxes that pass through main field magnets 7a and 7b respectively and interlink with stator windings 5 and first rotor windings 6, and the magnetic fluxes that pass through the main field magnets 7a and 7b respectively and short-circuit adjacent main field magnets 7b? and 7a? are generated. The short-circuited magnetic fluxes do not contribute to torque generation, therefore a favorable inner periphery magnetic circuit is not formed, and the torque received between a second rotor 4 and a first rotor 3 becomes small. When sub-field magnets 8a and 8b are provided, on the other hand, the short-circuited magnet fluxes interlink with the first rotor windings 6 by the sub-field magnets 8a and 8b, and an inner periphery magnetic circuit is formed, whereby the motor driving torque received between the second rotor 4 and the first rotor 3 increases.
