Provided is a two-shaft gas turbine with improved reliability that improves output power and efficiency and is stably operated by establishing a balance between the driving force of a compressor and the output power of a high-pressure turbine in the case where the two-shaft gas turbine is applied to a system in which the flow rate of fluid flowing into a combustor is increased compared with a simple cycle gas turbine.A portion of working fluid driving the high-pressure turbine is allowed to flow not into the high-pressure turbine but into a low-pressure turbine.
摘要:
Provided in one embodiment is a two-shaft gas turbine that exhibits improved reliability, output power, and efficiency. The turbine operates stably by establishing a balance between the driving force of a compressor and the output power of a high-pressure turbine in the case where the two-shaft gas turbine is applied to a system, in which the flow rate of a fluid flowing into a combustor is higher than a simple cycle gas turbine. A portion of the fluid driving the high-pressure turbine is allowed to flow not into the high-pressure turbine but into a low-pressure turbine.

The present invention provides a transonic blade that concurrently achieves reduction in shock loss at a design point and improvement in stall margin in blades operating in a flow field of transonic speed or higher in an axial-flow rotating machine. A cross-sectional surface at each of spanwise positions of the blade is shifted parallel to a stagger line connecting a leading edge with a trailing edge of the blade. A stacking line is shifted toward an upstream side of working fluid. The stacking line connects together respective gravity center positions of blade cross-sectional surfaces at spanwise positions in a range from a hub cross-sectional surface joined to a rotating shaft or an outer circumferential side casing of a rotating machine to a tip cross-sectional surface lying at a position most remote from the hub cross-sectional surface in a spanwise direction.

摘要:
A video-image selection unit cyclically acquires at least two types of video images. A replacing mask determination unit selects, for each acquired video image, a mask pattern for masking a video image acquired by the video-image selection unit by replacing some pixels composing the video image with pixels of a single color such that said some pixels are spatially removed. Based on the mask pattern, the video-image replacing unit replaces said some pixels composing the video image with the pixels of a single color. A video-image output unit outputs the video image for which the replacement was performed. When selecting a mask pattern, the replacing mask determination unit selects a mask pattern that is different from a mask pattern used for the last video image, the mask pattern being different in the position of pixels not to be replaced with pixels of a single color.

A display with a touch panel allowed to achieve high response performance while reducing power consumption is obtained. The display includes a plurality of display elements performing display based on picture signals supplied to a plurality of picture signal lines, respectively, a plurality of sensor elements outputting touch signals indicating detection of an external proximity object to a plurality of sensor signal lines (SGL), respectively, a detection section (a comparator 331) detecting each of the touch signals, a transfer output section (a D-type flip-flop 332 and an output buffer circuit 36) transferring and outputting a detection result of the detection section to outside, and a control section (a transistor switch SCW, a transfer clock control circuit 37 and a timing generator 35) controlling operations of the detection section and the transfer output section, allowing the transfer output section to operate in a case where the touch signal is detected in the detection section, and suspending an operation of the transfer output section in a case where the touch signal is not detected.
