  • Patent number: 9454160
    Abstract: According to one embodiment, a thermal recycling plant system includes a cooler cools coolant recycling thermal from coolant circulating in a load apparatus and which consumes energy while operating and a controller controls the cooler. The controller includes a calculator and a monitor. The calculator calculates an optimal temperature optimal for the coolant by optimization calculation for minimizing energy consumption under given conditions. The monitor monitors an operating state of the load apparatus to determine whether an abnormality exists in the load apparatus. The monitor controls the cooler to cool the coolant to a temperature lower than the optimal temperature calculated, on determining that an abnormality exists in the load apparatus.

    Abstract: A design supporting apparatus for a semiconductor device, includes an IR drop analyzing section configured to carry out an IR drop analysis on each of N (2 N) functional blocks, which operates independently on a semiconductor device, to generate an IR drop analysis result. An area of the semiconductor device is divided into small areas in a lattice. A mapping value generating section calculates a distribution of individual mapping values related to the small areas from the IR drop analysis result for each of the function blocks. A grouping section calculates a distribution of group mapping values from the distributions of individual mapping values for n (n?N) simultaneously operating functional blocks of the N functional blocks, and output group data indicative of the n simultaneously operating functional blocks when each of the group mapping values falls within a permission value.

  • Patent number: 7449802
    Abstract: In a vibration wave linear motor, a coupled driving contacting parts are respectively provided on the top and the bottom of a vibrator unit, and 2 upper and lower guide shafts which contact concave parts of the coupled driving contacting parts are supported by erecting parts of a supporting part. The lower guide shaft is pressed upward by spiral springs, so that the two guide shafts press and sandwich the vibrator. Alternating current voltages having different phases are applied to the vibrator unit, whereby the vibrator unit generates a vibration wave to generate elliptical rotation vibrations in the driving contacting parts. As a result, the vibrator, and the two guide shafts and the supporting part make a relative move in the shaft direction. Either the guide shafts or the vibrator is fixed, and the other is linked to an object to be driven.
