  • Patent number: 11959392
    Abstract: A rotor blade is a rotor blade to be attached to a rotor shaft rotatable about an axis, and includes a blade body extending in a radial direction with respect to the axis and having a blade-shaped cross-section orthogonal to the radial direction; a fillet portion provided on a radial outer side of the blade body and having a hollow portion formed therein; a shroud provided on a radial outer side of the fillet portion and extending in a circumferential direction; and a seal fin projecting from the shroud to an outer circumferential side and extending in a direction intersecting the blade body when viewed from the radial direction. A wall thickness on a suction side of the fillet portion is greater than a wall thickness on a pressure side of the fillet portion on a leading edge side of the blade body as demarcated by an intersection portion between the blade body and the seal fin serving as a boundary.

  • Patent number: 11943547
    Abstract: An image capturing unit captures an image including an embedded image that is printed on the basis of image data in which at least a color component has been modulated according to additional information. An adjustment unit adjusts a white balance of the image captured by the image capturing unit on the basis of an adjustment value associated with the embedded image. A processing unit processes image data of the image captured by the image capturing unit whose white balance has been adjusted by the adjustment unit to read the additional information in the image captured by the image capturing unit.

    Abstract: A sealing mechanism including a first seal member, a second seal member arranged so as to face the first seal member, and a deformed nucleus member arranged in a space formed at least partially between the first seal member and the second seal member, and becoming a nucleus of deformation in the sealing mechanism. The deformed nucleus member is configured by a combination of rod-like members and plate-like members respectively formed from a plurality of materials having different linear expansion coefficients, and is fixed to each of the first seal member and the seal member. The deformed nucleus member contracts in at least one direction on a cross-section of the seal groove, along with an increase in temperature of the deformed nucleus member. The first seal member and the second seal member respectively have abutment surfaces abutting on an inner surface of the seal groove or the facing surfaces.
