  • Patent number: 11096324
    Abstract: A fertilization design device calculates a fertilization amount of a field to be fertilized and includes the following units. A database reception unit receives one or both of growth data indicating growth potential of the field and soil data indicating plant growth potential of soil in the field and receives position data as position coordinate information for the field. A designated position reception and retrieval unit receives a freely selected position designated by a user and retrieves information of the freely selected position from the position data. A user input fertilization amount value reception unit receives a fertilization amount value freely set by the user for the freely selected position or for a range including the freely selected position. A calibration curve generation unit generates a calibration curve, based on one or both of the growth data and the soil data, the position data, and the fertilization amount value.

  • Patent number: 11073163
    Abstract: A centrifugal compressor includes impellers arranged in a plurality of stages in a direction of an axis line so that a working fluid flowing from one side inlet in the direction of the axis line is pumped outward in a radial direction, and a casing that surrounds the impellers, and that has a return channel through which the working fluid discharged from the impeller on a front stage side between the impellers adjacent to each other is guided inward in the radial direction so as to be introduced to the impeller on a rear stage side, and a plurality of return vanes disposed at an interval in a circumferential direction inside the return channel. The return vane is configured so that the thickness of a hub side in a leading edge side region is thicker than the thickness of a shroud side.

  • Patent number: 11035380
    Abstract: This diffuser vane (60), of which a blade height direction is aligned with an axial direction, has an airfoil shape in cross section orthogonal to the blade height direction, and comprises a body which, starting from a leading edge at the end on the radially inner side toward the radially outer side, extends toward the front side in an impeller rotating direction (R) and reaches a trailing edge at the end on the radially outer side. In the body of the diffuser vane, the turning angle of a shroud-side blade shape (S) that is the airfoil of an end face on one side in the axial direction is different from the turning angle of a hub-side blade shape (H) that is the airfoil of an end face on the other side in the axial direction. The airfoils form a transition continuously between the shroud-side blade shape and the hub-side blade shape. The turning angle of the hub-side blade shape is smaller than the turning angle of the shroud-side blade shape.
