A RAM_HIME used for integer pixel motion estimation by an IME stores integer pixel luminance data from a SDRAM while satisfying the conditions that improve efficiency in reading an extracted rectangular area. A RAM_HSME used for motion estimation of quarter-pixel accuracy by a SME stores partial quarter-pixel luminance data while satisfying the conditions that improve efficiency in obtaining a rectangular area after calculation by calculation. A RAM_HMEC used for chrominance data generation of quarter-pixel accuracy by a QPG stores integer pixel chrominance data from the SDRAM while satisfying the conditions that improve efficiency in obtaining rectangular areas after calculation by calculation.

In one embodiment, a steam device includes a high-temperature member and a low-temperature member. One surface of the high-temperature member is exposed to high-temperature steam, and the other surface is cooled by cooling steam having a temperature lower than the high-temperature steam. The low-temperature member is disposed to face the high-temperature member with a passage for the cooling steam therebetween and is formed of a material having a heat resistance lower than that of the high-temperature member. The steam device has at least one high-reflectance film selected from a first high-reflectance film, which is formed on the surface of the high-temperature member which is exposed to the high-temperature steam and has a higher reflectance with respect to infrared rays than the high-temperature member, and a second high-reflectance film, which is formed on the surface of the low-temperature member facing the high-temperature member and has a higher reflectance with respect to infrared rays than the low-temperature member.

摘要:
A plurality of blades are studded in a rotor disc integrated with the rotor along the circumferential direction of the rotor, a plurality of vanes are attached to a casing covering the rotor along the circumferential direction of the rotor, and an internal diaphragm disposed on rotor-side surfaces of the vanes in such a way that the internal diaphragm faces the rotor disc. The vanes and the blades adjacent to each other in the axial direction of the rotor form a turbine stage. A rotor-side cooling path is formed through the rotor disc in the axial direction of the rotor, and a diaphragm-side cooling path is formed through the internal diaphragm in the axial direction of the rotor, and a cooling medium flowing through the rotor-side cooling path diverts into the diaphragm-side cooling path and a labyrinth flow path provided between the internal diaphragm and the rotor.
