  • Patent number: 11135666
    Abstract: A tooth shape of the first tooth-shaped die part is formed have a constant tooth width from an upper end to a lower end and to correspond to a tooth width of a part in which a desired crowning has been produced. A tooth shape of the second tooth-shaped die part is formed to have a constant tooth width from an upper end to a lower end and to correspond to a tooth width of a central part, which is a part other than the part in which the desired crowning has been produced. A crowning forming method includes the steps of: forming a tooth shape on an outer circumference of the material by the tooth shape of the first tooth-shaped die part; and pressing the central part of the tooth shape of the material against the tooth shape of the inner circumference of the second tooth-shaped die part.

  • Publication number: 20200033068
    Abstract: A wick includes a porous body. The porous body includes a plurality of bubbles, a plurality of composite cells, and a plurality of communication holes. The plurality of bubbles has sizes in a range from 0.1 ?m to 50 ?m, both inclusive, in a cross section obtained when the porous body is cut. The plurality of composite cells is formed by spherical bubbles partially overlapping each other. Bubbles of pore sizes from 5 ?m to 10 ?m, both inclusive, are most present among the plurality of composite cells. The plurality of communication holes of 5 ?m or smaller is between the plurality of bubbles.
