  • Patent number: 9255494
    Abstract: Disclosed is a steam turbine power plant adapted to start operating safely even if prediction accuracy of its startup constraints cannot be obtained. The system calculates predictive values and current values of startup constraints of a steam turbine from process variables of plant physical quantities, next calculates in parallel both a first control input variable for a heat medium flow controller based on predictive values, and a second control input variable for a main steam control valve based on the current values, and while preferentially selecting the first control input variable, if the first control input variable is not calculated, selects the second control input variable instead. After the selection of at least one of the first and second control input variables, the system outputs an appropriate command value to the heat medium flow controller and the main steam control valve according to the kind of selected control input variable.

  • Patent number: 9177527
    Abstract: A multiple primary color display device includes a plurality of pixels located in a matrix including a plurality of rows and columns. The pixels are each formed of at least four sub pixels for displaying different primary colors, which can be sorted into n number of virtual pixels, and use each of the n number of virtual pixels as a minimum color display unit for providing display. The sub pixels which form each of the virtual pixels include a sub pixel common to another of the virtual pixels. When a line having a width corresponding to the n number of virtual pixels is displayed, two sub pixels which are located at both of two ends, in a width direction, of the line and display a certain identical primary color to each other have a luminance lower than the original luminance that the two sub pixels.
