摘要:
A pilot nozzle of a gas turbine combustor comprises a first structure, provided near a main nozzle of a combustor that injects fuel oil, having a flow channel for a fuel gas and an outlet for the fuel gas. The first structure diffusion-injecting the fuel gas obliquely forward through the outlet to maintain a flame and to aid ignition of the fuel oil injected from the main nozzle. There is further provided a second structure which circulates in whirls a combustion gas generated due to the combustion of the fuel gas.

A display has a display panel of a first aspect ratio and is able to display on the display panel an image of a second aspect ratio whose width element is larger than that of the first aspect ratio. The display has a gate driver, a data driver, and a timing controller. The gate driver sequentially selects gate lines of the display panel. The data driver stores data for one gate line and supplies the data to one of the gate lines selected by the gate driver. The timing controller supplies control signals to the gate and data drivers so that predetermined data is displayed in top and bottom non-image areas of the display panel during a vertical blanking period. The display is capable of displaying images of different sizes.

A display device includes a display panel having display pixels arranged in matrix formation. A first driver circuit sequentially supplies image data to vertical lines of the display panel in synchronism with a first clock signal. A second driver circuit sequentially drives horizontal lines in synchronism with a second clock signal. A control circuit controls a drive timing at which the second driver circuit sequentially drives the horizontal lines so that identical image data equal to one horizontal line is supplied, from the first driver circuit in synchronism with the first clock signal, to two consecutive horizontal lines every N horizontal lines (N is an integer) in accordance with an enlargement ratio at which an image is enlarged in a vertical direction and is displayed on the display panel.

摘要:
Calibration curve data is collected by measuring transmitted light intensities of a treating solvent while solvent temperature is varied. Also measured are a standard transmitted light intensity (transmitted light intensity of a standard treating solution prepared at a predetermined concentration and temperature) and a reference transmitted light intensity (transmitted light intensity of the solvent). Estimated transmitted light intensity of the solvent when its temperature is the same as that of the standard treating solution, is derived from the temperature of the standard treating solution and the calibration curve data stored. A correction factor is computed from a ratio between the reference transmitted light intensity and estimated transmitted light intensity. Then, transmittance of the standard treating solution (standard transmittance) is computed from the standard transmitted light intensity, reference transmitted light intensity and a correction factor. Subsequently, transmitted light intensity of a treating solution for actual use in treating substrates (sample transmitted light intensity) is measured. A sample transmittance of this treating solution is derived from the sample transmitted light intensity, reference transmitted light intensity and a correction factor. Concentration of the treating solution is controlled based on the standard and sample transmittance.

摘要:
A transition piece of a combustor which is sustainable even under conditions of more severe thermal environments is provided in the present invention. A transition piece of a combustor is provided with a cylindrical trunk main body, a cylindrical exit trunk part which is joined to the downstream end of the trunk main body and which cooperates with the trunk main body to constitute a trunk part, and an inner flange which extends from the downstream end part of the exit trunk part toward the outer periphery side of the exit trunk part. The exit trunk part and the inner flange are of an one-piece product. On the exit trunk part, there is formed a groove, and there is formed a cooling fluid passage which opens at the groove.
