Abstract: A blade ring assembly including: a turbine blade ring extending in a circumferential direction about an axis; a component to be cooled, disposed on an inner circumferential side of the turbine blade ring; and an outer circumferential side component disposed on an outer circumferential side of the turbine blade ring. The turbine blade ring has a cooling medium intake port leading from an outer circumferential surface to an inner circumferential surface of the turbine blade ring. The outer circumferential side component includes: a first wall portion which covers at least a portion of the cooling medium intake port from the outer circumferential side of the turbine blade ring; and a second wall portion which extends from an end portion of the first wall portion on the axially downstream thereof toward the outer circumferential side of the turbine blade ring.

Abstract: A first look-up table (10) outputs a result of dividing a horizontal component of a pixel address in the block by number of pixels in a horizontal component of the cell. A second look-up table (12) outputs a result of dividing a vertical component of a pixel address in the block by number of pixels in a vertical component of the cell. A third look-up table (14) outputs a residue as a result of dividing a horizontal component of a pixel address in the block by number of pixels in a horizontal component of the cell. A fourth look-up table (16) outputs a residue as a result of dividing a vertical component of a pixel address in the block by number of pixels in a vertical component of the cell. The output values of the first and second look-up tables (10,12) are addresses of the cell for burst access to the memory. The output values of the third and fourth look-up tables (14,16) are used as pixel addresses in the cell.

Abstract: An image processing device carries out processing in a processing unit of 3-blocks. Data of 192(=64×3)-pixels is required in the processing of 3-blocks. This is an amount of data corresponding to 16-cells. When 3-blocks and 16-cells are arranged along an scanning direction of an image, both ends of them in the scanning direction are aligned.

Abstract: A gas turbine combustor includes a pilot burner, a plurality of main burners disposed around the main burners on the radially outer side. Each of the main burners (2) includes an extension tube disposed at the downstream end. The outlet of the extension tube is shaped to have a radial edge which is parallel to the radial direction. In this manner, occurrence of flashback is effectively prevented.

Abstract: A quantization step determination part inputs an evaluation value (ACT_MB) indicating the dispersion in a macroblock and its average value (ACT_PIC). A subtracter obtains the difference between these values, and a multiplier multiplies the difference by raq (<1) to obtain a weighting value. Next, an adder adds the weighting value to an average quantization step value of source data, and finally a multiplier multiplies the sum by a step value adjustment factor ? (>1) to obtain a converted quantization step value (Qstep_AVC). This optimizes a bit allocation in accordance with an Activity value of the macroblock, to thereby improve the quality of image.

Abstract: An object of the present invention is to provide a binary arithmetic coding device that allows real-time processing with a higher image quality. At a timing at which a ternary data string for a target bit is outputted, an updated coding range width and an updated range width of less probability are outputted. For that reason, while a binary conversion unit (32) and an f value retention processor (33) convert the ternary data string into a binary data string to output a coded bit, a binary arithmetic re-normalization unit (31) is allowed to perform a processing of binary arithmetic coding for the next bit.
