  • Patent number: 9815418
    Abstract: Numerous fine projections (20) are formed interspersed on a plate-shape member (18), and the neutral plane (S) of each fine projection (20) is inclined at an inclination angle ? to the normal line (O) such that the contact center (Q) does not overlap with the base part in the plane direction of the surface (22), so when a pressing load (F) is applied, the moment acting on the fine projections (20) is large, and the fine projections (20) easily deform to bend in the respective inclination direction. By this means, the tactile softness (cushion properties) are improved by preventing the fine projections (20) from undergoing simple compression deformation in the axial direction, and stick-slip due to friction between the fine projections (20) and the surface (22) is avoided, making it possible to obtain a smooth and stable tactile softness.

  • Publication number: 20160115441
    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.
