摘要： Since the drive data for display or their correction values are stored in correspondence with the combination of the upper bits of the current frame image data and the upper bits of the previous frame image data, the capacity of the high-speed memory circuit that stores the conversion table can be reduced. Accompanying the reduction in the capacity of the conversion table, since the precision of the display drive data or their correction values becomes lower, an interpolation circuit is provided and, by means of an interpolation calculation the display, drive data or their correction values having increased precision is generated and consequently the input image data is corrected to generate the display drive data.

摘要： A gas turbine combustor transition piece outlet structure enabling a reduction in the temperature difference of a flange formed at the transition piece outlet. A flange is formed with a cooling medium channel along the inner circumference, cooling medium channels along the left and right side surfaces, and heating medium channels along the top and bottom surfaces. By cooling the inner circumference or the side surfaces of the flange by a cooling medium or heating the top and bottom surfaces of the flange by a heating medium, the temperature difference of the flange is reduced. Note that as the cooling medium, it is possible to use compressed air, low temperature steam, or fuel, while as the heating medium, it is possible to use high temperature steam or combustion gas.

摘要： The state of combustion oscillation in the combustor of a turbine of a power plant is monitored from a remote monitoring center. To monitor the combustion oscillation state, combustion oscillation data on the combustor is separated into two types of data: the first data obtained on a real-time basis, and the second data including representative values within a predetermined period of time obtained from the first data. In the normal state, a low-speed communications mode is used to send the second data, which is monitored at the monitoring center. If an abnormal state is predicted as a result of monitoring the second data, the high-speed communications mode is used to send the first data, and more detailed combustion oscillation data is monitored at the monitoring center. When a critical state is predicted, an instruction is sent to the local site to switch the operation mode over to the low load operation mode.

摘要： A gas turbine combustor, in which plural pre-mixers that inject fuel into swirling air passages are arranged to surround a pilot burner, and a pilot flame, guided by a pilot cone in the shape of a flaring pipe and provided at the rear end of the pilot burner, is mixed with a pre-mixture blown out from the pre-mixers to obtain a combustion gas, comprising flame-stabilizing means. The flame-stabilizing means lower the disturbance in a region where the pre-mixture and the pilot flame are mixed or stabilize the pilot flame, so that the flame generated by igniting the pre-mixture with the pilot flame is stabilized. By stabilizing the flame, combustion with a leaner air-fuel ratio is possible, and thereby the amount of NOx can be decreased.

摘要： A steam-cooling gas turbine in which cooling steam is fed from a center portion of a rotating shaft and recovered through passages disposed at the outer side of the center portion with steam leaking through a seal portion from a feeding steam being effectively recovered. Feed steam (30) serving as coolant is supplied to a cavity (27) from a inner cylinder (10) and hence fed to moving blades (11, 12) through recesses (40) formed in a coupling portion (26) interposed between a final-stage disk (24) and a turbine shaft (1), steam feeding pipes (15) and steam feeding passages (11a, 12a). After cooling of the moving blades, steam (31) is recovered through steam recovering passages (11b, 12b), steam recovering pipes (16), radial steam-recovering passages (17), axial steam-recovering passages (18) and outlet openings (5a). The coupling portion (26) is forced to hermetically close under thermal stress, whereby leakage of the feed steam (30) is prevented. Steam leaking through a seal portion constituted by stationary and rotatable seal fin assemblies (4a, 4b) can be effectively recovered. The inner cylinder (10) can move in the axial direction through cooperation of piston rings (43) and a centering piece (6) adapted for absorbing thermal stress induced in the inner cylinder (10). Upstream tip end portions of steam feeding pipes (15) and steam recovering pipes (16) are secured onto a side surface of the first-stage disk (21) through sleeves removably fitted thereto.
