  • Publication number: 20110169436
    Abstract: A control apparatus controls an inverter (electric power converter circuit) which is connected for selectively applying a plurality of voltage levels to each phase of a polyphase rotary machine. In each of successive control periods, the apparatus determines the inverter operation state (combination of respective voltage levels applied to the phases) to be set for the succeeding control period, by performing prediction calculations based on a model of the rotary machine, for each of a plurality of candidates for the next operation state, to select an optimum candidate. The candidates are restricted to those operation states whereby the voltage level of no more than one of the phases will be changed, at changeover to the operation state of the next control period.

  • Publication number: 20110050137
    Abstract: In an apparatus, a predicting unit predicts, based on a target value of a drive mode of a power converter at a next timing, a first value of a controlled variable. The drive mode is indicative of a switching-state of each of a plurality of switching elements. The target value of the drive mode of the power converter at the next timing is temporarily set at a present timing prior to the next timing. A driving unit drives the plurality of switching elements based on the target value of the drive mode at the next timing while limiting a number of switching-state changes in the plurality of switching elements from the present timing to the next timing as long as the deviation between the predicted first value of the controlled variable at the further next timing and a command value therefor is within a threshold range.

  • Patent number: 7724267
    Abstract: An information processing apparatus has a pointing device for designating a position of an arbitrary point with respect to a reference point O, and a processor of the information processing apparatus detects a position of the point designated by the pointing device with respect to the reference point O at every unit of time, and calculates an operation vector AB respectively regarding a point A and a point B detected before and after as a starting point and an ending point. The calculated operation vector AB is orthogonally-projected onto a strait line vertical to a vector OA respectively regarding the reference point O and the point A as a starting point and an ending point. Information processing is performed on the basis of a component vector thus obtained from the operation vector AB.

  • Patent number: 7521087
    Abstract: A catalyst composition is applied to an interior of a hollow substrate. The composition is coated on the substrate by immersing the substrate into a vessel containing a bath of coating slurry. A vacuum is then applied to the partially immersed substrate. The intensity of the vacuum and its application time is sufficient to draw the coating slurry upwardly from the bath into each of a plurality of channels located in the interior of the hollow substrate. After removing the substrate from the bath, it is rotated 180°. A blast of pressurized air is applied at an intensity and for a time sufficient to distribute the coating slurry within the channels of the substrate to form a uniform coating profile therein.
