Abstract: In the thermal power system, the electricity production efficiency may be improved by providing turbine members having the improved high temperature characteristic over the corresponding prior art turbine members. Turbine members may be provided by using high resistant steels composed of any one or ones selected from the group consisting of the components, including 0.08 to 0.13% of carbon (C), 8.5 to 9.8% of chromium (Cr), 0 to 1.5% of molybdenum (Mo), 0.10 to 0.25% of vanadium (V), 0.03 to 0.08% of niobium (Nb), 0.2 to 5.0% of tungsten (W), 1.5 to 6.0% of cobalt (Co), 0.002 to 0.015% of boron (B), 0.015 to 0.025% of nitrogen (N), and optionally, 0.01 to 3.0% of rhenium (Re), 0.1 to 0.50% of silicon (Si), 0.1 to 1.0% of manganese (Mo), 0.05 to 0.8% of nickel (Ni) and 0.1 to 1.3% of cupper.

Abstract: A multi-window management apparatus includes: an activating icon display unit for displaying activating icons 60, 62, 64 and 66 on a display screen 56; a window display unit opening, when activating icon 64 is designated, a window 72 corresponding to activating icon 64 next to activating icon 64; and a window arranging unit for rearranging and displaying, when activating icon 64 is designated, a window 68 that has been open, and activating icons 60, 62 and 66 other than the designated activating icon 64, such that these are arranged along the longer side direction of display screen 56 not to be overlapping on an area where the new window 72 is to be opened.

Abstract: Provided is a heat-resisting steel, which can be operated stably under a high-temperatures steam environment and which provides an excellent economic advantage. The particular heat-resisting steel comprises 0.25 to 0.35% by mass of C, not more than 0.15% by mass of Si, 0.2 to 0.8% by mass of Mn, 0.3 to 0.6% by mass of Ni, 1.6 to 1.9% by mass of Cr, 0.26 to 0.35% by mass of V, 0.6 to 1.1% by mass of Mo, 0.6 to 1.4% by mass of W, 1.3 to 1.4% by mass of Mo+W/2, and the balance of Fe and unavoidable impurities.
