  • Patent number: 9112436
    Abstract: In a system for controlling a controlled variable of a rotary machine having plural-phase input terminals of the rotary machine in which plural-phase AC power is applied from an AC power applying module to the input terminals, a command-voltage setting module sets, based on a request value for the controlled variable, plural-phase AC command voltages for the plural-phase AC power as a feedforward manipulated variable. A current obtaining module obtains plural-phase AC currents flowing in the respective plural-phase input terminals of the rotary machine. An amplitude correcting module corrects the amplitude of at least one of the plural-phase AC command voltages based on the magnitudes of the plural-phase AC currents.

  • Publication number: 20150148174
    Abstract: Providing an electric vehicle transaxle suppressing occurrence of wear, seizure, etc. of a one-way clutch as compared to a conventional one. When an electric motor MG is driven and a one-way clutch 34 moves in a rotation axis C1 direction, the one-way clutch 34 comes into contact with a flange portion 46b of an inner race 46 or a supporting portion 30b of a transaxle housing 30 via a sliding washer 74 and, therefore, direct contact is prevented between the one-way clutch 34 and the flange portion 46b of the inner race 46 or the supporting portion 30b and wear, seizure, etc. of the one-way clutch 34 are suppressed.

  • Publication number: 20150085388
    Abstract: An optical module and a manufacturing method thereof are provided which can improve positioning accuracy between parts. A barrel and a lens holder are prepared, the lens holder is fitted into a cylindrical portion from a collar portion side of the barrel, and the barrel and the lens holder are assembled. In this case, the barrel and the lens holder are assembled with a brazing material inserted therebetween. The assembled barrel and lens holder are heated, and the brazing material is melted to thereby perform brazing. Lens glass is sandwiched between metal dies and a lens is press-molded using a pressing apparatus. In this case, positioning of press molding is performed using the barrel for which a small linear expansion coefficient is set as a reference.
