Abstract: A rotation transmission disc includes: an outer circumferential portion on which a load acts when rotation is transmitted; a center opening portion formed inside the outer circumferential portion; and a plurality of attachment holes for attachment of the rotation transmission disc 1 to a rotating element. A first crosspiece portions are formed in each of ranges of divided angles formed by two adjacent attachment holes with respect to a center of the rotation transmission disc. The first crosspiece portion extends from a load point, which is an intersection between a straight line extending in a radial direction to internally divide the divided angles at a predetermined angular ratio and a load radius position of the outer circumferential portion, to one of the attachment holes forming the divided angles. The second crosspiece portion extends from the load point to the other attachment hole of the attachment holes forming the divided angles.

Abstract: Provided is a method for charging, with ceramic, open pores formed in a matrix of a ceramic matrix composite that includes the matrix and reinforcing fibers provided in the matrix. The ceramic comes to constitute the matrix. The method includes repeating the following steps (A) and (B) in a state where the ceramic matrix composite is arranged in a liquid material serving as a matrix material. At the step (A), the ceramic matrix composite is heated such that the liquid material is brought into a film-boiling state, and the ceramic derived from the liquid material is thereby generated in the open pores. At the step (B), the ceramic matrix composite is cooled until a temperature of the ceramic matrix composite becomes lower than a boiling point of the liquid material.
