  • Patent number: 11879722
    Abstract: An objective of the present invention is to provide a method, or the like, for estimating the convergence of dimensional changes in a molded article over time, by utilizing the polarization intensity of terahertz waves. The present invention provides a method for estimating the convergence of changes in the dimensions of a molded article over time, the method comprising: irradiating a molded article with terahertz waves at multiple positions thereon, wherein the molded article is irradiated with the terahertz waves at each position thereon in multiple orientations about the optical axis; measuring polarization intensities of the terahertz waves transmitted through or reflected from the molded article; and determining whether the polarization intensities at the multiple positions are in a given relationship with each other.

  • Patent number: 11059207
    Abstract: Provided is a method for producing a composite member formed by bonding a base material and a resin member. The method includes: a surface treatment step of forming micro-order or nano-order asperities on a surface of a base material; and a bonding step of directly bonding, by injection molding, a resin member to the surface of the base material that has the asperities formed in the surface treatment step. In addition, the composite member includes: a base material having micro-order or nano-order asperities on a surface thereof; and a resin member that is in direct contact with the surface of the base material.
