  • Publication number: 20230007158
    Abstract: In an image processing apparatus, a first correction unit corrects imaging data acquired from an infrared imaging device, based on a first correction table, and outputs first corrected data. A second correction unit generates a second correction table for the imaging data in a state in which a shutter is closed, and outputs second corrected data based on the second correction table. A saturated region detection unit detects a saturated region in the imaging data. A shutter control unit performs closing control for the shutter, based on a result of detection of the saturated region. An abnormal pixel detection unit detects whether or not the imaging data acquired in the state in which the shutter is closed includes an abnormal pixel. A selection unit selects and outputs either the first corrected data or the second corrected data in accordance with a result of detection by the abnormal pixel detection unit.

  • Publication number: 20220389535
    Abstract: Provided is a method for producing a Ni- or Ti-based alloy product, the method capable of locally increasing the cooling rate and effectively cooling. The method includes the steps: preliminarily processing a hot working material of a Ni- or Ti-based alloy after hot working into a predetermined shape; heating and holding the material at a solution treatment temperature to obtain a material held in a heated state; and cooling the material held in a heated state to obtain a solution-treated material. The cooling step includes placing a flow path-forming member having a space for forming a flow path for a fluid on a surface of the material held in a heated state to form a fluid flow path defined by the surface of the material held in a heated state and an inner surface of the space of the flow path-forming member; and allowing a fluid to flow in the fluid flow path so that the fluid in the flow path locally cools a part of the surface of the material held in a heated state.

  • Patent number: 11417035
    Abstract: An X-ray tomosynthesis apparatus accurately extracts a region of a small high absorber in a subject on 2D measurement projection data. When pieces of the 2D measurement projection data for each of a plurality of projection angles are arranged in a projection angle direction, the 2D measurement projection data is shifted in a 2D plane so that part or all of a range of a high absorber region included in the 2D measurement projection data overlaps at least a range of the high absorber region included in 2D measurement projection data at an adjacent projection angle in an in-plane direction of the 2D plane. The 2D measurement projection data for each of the plurality of projection angles after shifting is arranged in the projection angle direction to obtain 3D measurement projection data, and a 3D region is obtained from a first start point by a region expansion process.

  • Patent number: 11333043
    Abstract: A steam turbine plant includes high-pressure gland portions, low-pressure gland portions, a gland regulator line, and a rotor-driving steam supply line. The high-pressure gland portions supply gland steam to gaps of ends of a high-pressure turbine rotor, and thereby seal the gaps. The low-pressure gland portions supply the gland steam to gaps of ends of a low-pressure turbine rotor, and thereby seal the gaps. The gland regulator line guides the gland steam from the high-pressure gland portion to the low-pressure gland portion. The rotor-driving steam supply line branches off from the gland regulator line, and supplies some of the gland steam to a main steam flow passage in a low-pressure casing.
