  • Publication number: 20130244328
    Abstract: This invention provides a means for modifying surface properties of a cell culture substrate under specific conditions, to thereby regulate regions to which cells are allowed to adhere or are not allowed to adhere, depending on cell type. This invention relates to a method of cell culture comprising steps of: applying a positive potential to a conductive region of a substrate comprising a base material having a conductive region and a non-cell-adhesive membrane coupled thereto with the aid of silane, so as to separate the non-cell-adhesive membrane from the substrate; and culturing cells in a region from which the non-cell-adhesive membrane has been separated.

  • Publication number: 20100307180
    Abstract: An outer surface of a cold-storage container (or a refrigerant tube) is provided with a plurality of protrusion portions or recess portions. A cooling air passage, in which air flows to cool a space to be cooled in a cold storage time and in a cold release time of the cold storage material, is provided to contact a surface of the refrigerant tube on a side opposite to the cold storage container bonded to the refrigerant tube. The refrigerant tubes and the cold storage container form therebetween a cold-storage side air passage by the protrusion portions or the recess portions, such that air flows in the cold-storage side air passage separated from the cooling air passage. For example, the cold-storage side air passage is provided with a slanting space that causes condensed water or ice generated in the cold storage time to be drained along the cold-storage side air passage.
