  • Patent number: 9916084
    Abstract: A method, and associated apparatus and system and program product, for enlarging or reducing an image. The image is displayed on a display screen. A pointing operation is detected. The pointing operation points to, with a single-touch gesture using pointing means on the display screen, a first figure indicative of a range of the image to be enlarged or reduced and a second figure indicative of a size of the enlarged or reduced range. In response to the detection of the pointing operation, an enlarged or reduced image is displayed after the enlarged or reduced image is obtained by enlarging or reducing the image at an enlargement or reduction ratio determined based on the first figure and the second figure.

  • Patent number: 9287756
    Abstract: A rotating electrical machine control apparatus includes a position information generator and a controller, where a reset request is given from the controller, the position information generator stores position information in accordance with a first signal indicating the rotation position of a rotating electrical machine in a position storage portion, and thereafter updates the position information stored in the position storage portion on the basis of a second signal. The controller gives a reset request to the position information generator, and determines an abnormality of the position information on the basis of the position information obtained before and after the reset request is given.

  • Patent number: 8348020
    Abstract: An elevator control device includes a vector controller that calculates a voltage command required for driving an elevator cage, a carrier frequency switch circuit that outputs a carrier frequency signal, and a power converter that performs PWM control based on the voltage command and the carrier frequency signal, generates an AC power and supplies the AC power to an AC motor. The carrier frequency switch circuit changes the carrier frequency signal when a torque command for driving the AC motor reaches a torque limit value. Thus, it is possible to continuously operate an elevator without causing damage to a switching element of the power converter.
