  • Rotor, motor, method for manufacturing rotor, and method for manufacturing motor
    Patent number: 11296563
    Abstract: A rotor includes a rotor core, permanent magnets, and a tubular non-magnetic cover. The permanent magnets are arranged along an outer surface of the rotor core in the circumferential direction. The permanent magnets each include a curved outer surface as viewed in the axial direction. The tubular non-magnetic cover covers the outer surfaces of the permanent magnets. The rotor core includes at least two stacked cores. Each stacked core includes a stack of core sheets. One of the stacked cores is formed from a material having a lower hardness than the other stacked core.
    Type: Grant

  • VIDEO PROCESSING APPARATUS AND VIDEO DISPLAY APPARATUS
    Publication number: 20160057436
    Abstract: In a video processing apparatus, even when a resolution of a video signal to be decoded is switched, scaling is performed so as to match with a display size of a display portion for outputting to the display portion and the display portion is caused to display a video matching with the display size. A video processing apparatus according to the present invention includes a decoding portion that decodes a video signal, and a scaling portion that applies scaling processing to a video frame indicated by the video signal decoded by the decoding portion. The decoding portion gives resolution information of the video frame indicated by the decoded video signal to the scaling portion, and the scaling portion applies scaling processing to the video frame based on the resolution information.
