Abstract: An inclination sensor that can accurately detect an inclination angle with respect to a horizontal direction while suppressing drift in output values from an acceleration sensor and a data acquisition device including the inclination sensor are described. The inclination sensor includes a gimbal mechanism that is rotatably supported around a first shaft and a second shaft, a first motor that rotates the first shaft, a second motor that rotates the second shaft, a first encoder that detects a rotation angle of the first shaft, a second encoder that detects a rotation angle of the second shaft, an acceleration sensor that is disposed in the gimbal mechanism, and a control unit that arithmetically determines the inclination angle with respect to the horizontal direction.

Abstract: A turbine blade cascade structure includes a plurality of blades arranged in series in a circumferential direction on a wall surface, in which a corner portion defined by the wall surface and a front edge portion of each of blade bodies supported by the wall surface, to which a working fluid flows, includes a cover portion (fillet) that extends toward an upstream side of a flow of the working fluid. The turbine blade cascade structure is capable of reducing the secondary flow loss of the secondary flow in spite of the fluctuation of an incident angle of the working fluid flowing to the front edge portion of the blade body.

Abstract: A turbine blade cascade structure includes a plurality of blades arranged in series in a circumferential direction on a wall surface, in which a corner portion defined by the wall surface and a front edge portion of each of blade bodies supported by the wall surface, to which a working fluid flows is provided with a coating portion that extends toward an upstream side of a flow of the working fluid. The turbine blade cascade structure is capable of reducing the secondary flow loss of the secondary flow in spite of the fluctuation of an incident angle of the working fluid flowing to the front edge portion of the blade body.

Abstract: A surface roughness measuring method including, measuring surface roughness and a surface color image information of a plurality of representative points of a surface of a first object to be measured, and preparing a calibration information indicating the relationship between color stimulus values for the surface color image information and the surface roughness. The surface roughness measuring method further includes taking a surface color image information of a plurality of measuring points of a surface of a second object to be measured, obtaining color stimulus values from the surface color image information of the measuring points, converting the color stimulus values of the measuring points to surface roughness of the measuring points using the calibration information, and displaying the surface roughness of the measuring points of the second object to be measured as a surface information.

Abstract: Embodiments of the invention provide an IGCC which achieves improved plant thermal efficiency by using a cooling steam supply system that cools the high-temperature sections of the gas turbine 34. Embodiments of the invention further provide and IGCC in which the cooling steam recovery system recovers steam after cooling the gas-turbine high-temperature section and makes practical re-use of the energy and substances within the system. Therefore, embodiments of the invention can reduce or eliminate the degradation of certain equipment by cooling the high-temperature sections. Methods are provided for increasing the thermal efficiency o an IGCC.

Abstract: A gas turbine plant comprises an air compressor, a gas turbine combustor and a gas turbine, which are operatively connected in series. In the gas turbine plant, an air compressor shaft is accommodated in the air compressor and composed of discs piled up along an axial direction of the air compressor shaft, a gas turbine shaft is accommodated in the gas turbine and composed of discs piled up along an axial direction of the gas turbine shaft, and an intermediate shaft is interposed between the air compressor shaft and the gas turbine shaft.
