  • Patent number: 8912794
    Abstract: An angle detecting device has a combined structure of plural resolvers, but is simple and is easily produced, and has redundancy reducing the risk of failure. The angle detecting device has two resolvers which are combined in the axial direction and has a stator core 100. The stator core 100 is formed by laminating a first stator core 103 on a second stator core 104. The first stator core 103 is provided with plural salient poles 101 which extend to a center of an axis. The second stator core 104 is provided with plural salient poles 102 which extend to the center of the axis. The salient poles 101 and 102 differ in position when viewed from the axial direction, and the salient poles 102 are positioned between the adjacent salient poles 101 when viewed from the axial direction.

  • Publication number: 20140355392
    Abstract: Disclosed is a radio-controlled timepiece. The radio-controlled timepiece includes an oscillating unit, a display unit, a display driving unit, an error storage unit, a radio wave receiving unit, and a frequency setting unit. The display driving unit drives the display unit with a driving signal of a predetermined driving waveform frequency generated by the clock signal output by the oscillating unit. The error storage unit stores error data of an oscillating frequency. The radio wave receiving unit tunes to a receiving frequency of a radio wave including time information, and receives the radio wave. The frequency setting unit sets the driving waveform frequency based on the error data so that the receiving frequency does not overlap with a higher order harmonic wave of the driving waveform frequency during a period that the radio wave is received.

  • Patent number: 8811486
    Abstract: A motion detection portion of a video encoding apparatus conducts motion detection on each of frame macroblocks and field macroblocks to calculate motion vectors and respective detection cost. A motion vector evaluation value calculation portion calculates an evaluation value of the size of motion vectors. A motion vector threshold determination portion compares the evaluation value of the size of motion vectors to a predetermined threshold to determine whether the target area is a moving area or a still area. If the target area is a moving area, it is determined whether frame or field macroblock mode is to be used by comparing the detection costs. If the target area is a still area, it is determined whether frame or field macroblock mode is to be used in accordance with the size of the sum of absolute values of differences between neighboring pixels in a vertical direction regarding the frame macroblock and field macroblock.
