  • Patent number: 10752183
    Abstract: A laminated composite interior part includes a first member made of synthetic resin and having a mating surface; and a second member made of elastically deformable synthetic resin and having a plate portion substantially parallel to the mating surface. The plate portion has integrally-formed and interspersed protrusions protruding toward the mating surface. The second member is placed on the first member with distal end portions of the protrusions being in contact with the mating surface. Cushioning properties are provided by elastic deformation of the protrusions, caused as the protrusions' distal end portions are relatively pressed against the mating surface. Flexural rigidity of each of the protrusions against a compressive load is anisotropic about its axis, so that the protrusion is flexurally deformed in one direction about its axis with the distal end portion thereof sliding on the mating surface. Surface roughness of the mating surface is less than 0.20.

  • Publication number: 20200216802
    Abstract: By using a graft polymer comprising a dendritic polymer with a styrene skeleton and a hydrophilic polymer grafted to a terminal thereof, a temperature-responsive substrate for cell culture having a temperature-responsive surface for cell culture that allows cells to be cultured with high efficiency and which yet allows cultured cells to be exfoliated in a short period of time and with high efficiency by simply changing the temperature of the substrate surface can be prepared conveniently. If this temperature-responsive substrate for cell culture is used, cells obtained from a variety of tissues can be cultured with high efficiency. If this culture method is utilized, cultured cells can be exfoliated intact in a short amount of time with high efficiency. In addition, by using this graft polymer, a wide range of peptides and proteins can also be separated by simply changing the temperature of a chromatographic carrier.
