  • Patent number: 9667972
    Abstract: When compression encoding processing of an image is performed in units of macroblocks using a pipeline structure, an application of a skip mode or the like according to MPEG4AVC to compression encode an encoding target block requires motion vectors and the like of adjacent blocks of the encoding target block. However, depending on a structure of the pipeline stages, the motion vectors may not be determined. In such cases, the skip mode cannot be applied to compression encode the encoding target block. This problem can be solved by (i) calculating all motion information candidates, of the encoding target block, corresponding to all motion information selectable by a previous block of the encoding target block, and (ii) selecting, as the motion information of the encoding target block in the skip mode, the motion information corresponding to the motion information determined for the previous block.

  • Publication number: 20160290398
    Abstract: A rolling bearing includes an outer ring, an inner ring, a plurality of balls disposed between the outer ring and the inner ring and allowed to roll, and a snap cage that is made of resin and holds the balls. The snap cage includes an annular main portion and a plurality of cage bars. The cage bars each protrude from a right side surface of the main portion. Pockets are formed between the cage bars to house the respective balls. An inner circumferential surface and an outer circumferential surface of each of the cage bars in a radial direction have respective tilted surfaces that form a tapered shape in an axial direction. This allows lubricant oil to flow well in the rolling bearing in both directions.

  • Patent number: 9189989
    Abstract: A plasma display system restricts peak data traffic when a shared memory is used. In the plasma display system, a control unit prohibits a moving picture decoder from accessing a shared memory while an SF reading unit is reading, from the shared memory, SF pixel data which is information about respective cells to be lit in a plurality of subfields. On the other hand, the control unit permits the moving picture decoder to access the shared memory while the SF reading unit is not reading the SF pixel data from the shared memory during a sustain discharge period.

  • Patent number: 8480305
    Abstract: A cage has a ring portion, and a plurality of column portions that protrude from the ring portion, that are arranged in the circumference direction. Each column portion has a column portion radially inward section that forms a bearing-radial-direction inward side portion, and a column portion radially outward section that is connected to the radially inward section at its radially outer end position, so as to protrude on both sides in the circumferential direction from the radially inward section. A connection position at which the radially outward section is connected to the radially inward section is adjusted to a position radially outward of a pitch circle position of the plurality of the balls that are held in the respective pockets. Thus, the thickness of the radially inward section at the connection position is larger than the thickness of the radially inward section at the pitch circle position.
