摘要:
An image processing apparatus includes an image processing block, a plurality of control blocks, and a plurality of register sets. The image processing block carries out a specific process based on input setting data. Each of the plurality of control blocks controls the specific process of the image processing block independently. The plurality of register sets are used in data communication between each of the plurality of control blocks and the image processing block. When any one of the plurality of control blocks is controlling the specific process of the image processing block, each of the remaining control blocks performs data communication with the image processing block using the corresponding register set.

A stainless steel pipe for use in oil wells which has a high strength having a YS of 654 MPa or more and superior corrosion resistance even in a severe corrosive environment in which CO2 and are present and the temperature is high, such as up to 230° C. The pipe contains on a mass percent basis: 0.005% to 0.05% of C; 0.05% to 0.5% of Si; 0.2% to 1.8% of Mn; 0.03% or less of P; 0.005% or less of S; 15.5% to 18% of Cr; 1.5% to 5% of Ni; 1% to 3.5% of Mo; 0.02% to 0.2% of V; 0.01% to 0.15% of N; 0.006% or less of 0; and the balance being Fe and unavoidable impurities, in which Cr+0.65Ni+0.6Mo+0.55Cu−20C≧19.5 and Cr+Mo+0.3Si−43.5C−0.4Mn−Ni−0.3Cu−9N≧11.5 are satisfied (where Cr, Ni, Mo, Cu, C, Si, Mn, and N represent the respective contents on a mass percent basis). In addition, quenching treatment and tempering treatment are preferably performed, so that the pipe preferably has a texture containing a martensite phase as a primary phase and 10 to 60 percent by volume of a ferrite phase, or further containing 30 percent by volume or less of an austenite phase. Furthermore, at least one of Al, Cu, Nb, Ti, Zr, W, B, and Ca may also be contained.

A stainless steel pipe for use in oil wells is proposed which has a high strength having a YS of 654 MPa or more and superior corrosion resistance even in a severe corrosive environment in which CO2 and Cl− are present and the temperature is high, such as up to 230° C. The pipe contains on a mass percent basis: 0.005% to 0.05% of C; 0.05% to 0.5% of Si; 0.2% to 1.8% of Mn; 0.03% or less of P; 0.005% or less of S; 15.5% to 18% of Cr; 1.5% to 5% of Ni; 1% to 3.5% of Mo; 0.02% to 0.2% of V; 0.01% to 0.15% of N; 0.006% or less of O; and the balance being Fe and unavoidable impurities, in which Cr+0.65Ni+0.6Mo+0.55Cu−20C≧19.5 and Cr+Mo+0.3Si−43.5C−0.4Mn—Ni−0.3Cu−9N≧11.5 are satisfied (where Cr, Ni, Mo, Cu, C, Si, Mn, and N represent the respective contents on a mass percent basis).

An imaging apparatus includes an omnidirectional imaging unit that captures and generates an image of a visual field all around an axis as omnidirectional image data; an image converter that converts at least a part of the omnidirectional image data, which is generated by the omnidirectional imaging unit, to image data having a rectangular display area and thereby generates conversion image data; and a display unit that displays an image corresponding to the conversion image data, which is generated by the image converter. The omnidirectional image data forms an annular shape.

摘要:
An object of the present invention is to appropriately and easily evaluate a photosynthetic function of a photosynthetic sample contained in an evaluation sample.An evaluation method for photosynthetic sample according to the present invention is for evaluating a state of a photosynthetic sample with a photosynthetic function based on temporal data of a luminescence amount of delayed luminescence emitted from the photosynthetic sample. First, characteristic values that indicate characteristics are determined for a plurality of time periods in the temporal data. An evaluation value is then computed by weighting the characteristic values. The state of the photosynthetic sample is then evaluated based on the evaluation value.
