  • Publication number: 20240136959
    Abstract: A motor controller includes a plurality of inverters that supply power to a corresponding motor of a plurality of motors through pulse width modulation control, a direct current power supply that supplies power to the plurality of inverters, and a capacitor connected parallel to the direct current power supply. Each of the plurality of inverters is categorized into one of a plurality of groups based on a switching frequency. All inverters in each of the groups have corresponding carrier signals being triangular wave signals determined based on a reference frequency assigned to the group. At least one of the triangular wave signals has at least one of a frequency or a phase different from a frequency or a phase of another triangular wave signal of the triangular wave signals.

  • Publication number: 20150111676
    Abstract: At least one member composing a chain bearing, e.g., a pin, includes a surface layer composed of vanadium carbonitride (VCN) coating on a surface of a base material of the one member. An oxide (VO) film having a predetermined thickness is also formed on a surface of the surface layer such that the oxide film is interposed between the surface layer and another member, e.g., a pin hole, composing the bearing. The VO film is suppressed from being formed excessively by the VCN coating even under a severe environment.

  • Patent number: 8139273
    Abstract: In an apparatus for detecting a stain on a paper-sheet, a type and a transportation direction of the paper sheet are identified, and the information on whether each extraction target area of a read image corresponds to a white portion or a patterned portion of the paper sheet are stored. When the extraction target area corresponds to the white portion, a pixel having a lowest pixel value is extracted from a plurality of pixels constituting the extraction target area, and the read image is compressed into the pixel values of the extracted pixels as representative values, to generate a compressed image including a characteristic of a fine graffiti line drawn with a pencil or the like.

  • Patent number: 5074185
    Abstract: An envelope-generating apparatus for an electronic musical instrument is disclosed. The apparatus which generates an envelope signal for a musical tone includes a rate detector for detecting the actual rate-of-change of the envelope signal at an instant before quick-attenuation of the signal is to commence, and a quick-attenuation controller for first setting a predetermined attenuation rate for the envelope signal based on the actual rate-of-change detected by the rate detector and thereafter controlling quick-attenuation of the envelope signal.
