  • Publication number: 20160138853
    Abstract: The present disclosure relates to a refrigerator, and more particularly, to a refrigerator in which two or more accommodating spaces are provided and doors are provided at the accommodating spaces, respectively. Handles are formed in the doors so that the handles are inconspicuous from an external appearance of the refrigerator, thereby newly designing the external appearance of the refrigerator. In addition, even though two doors are disposed to be adjacent to each other, accessibility to the handle may be ensured, thereby easily opening and closing the doors of the refrigerator.

  • Publication number: 20140311662
    Abstract: In a method for fabricating an embedded pattern using a transfer-based imprinting, an adhesive layer is formed on a substrate. The adhesive layer has a photo curable resin. A stamp having a protruded pattern is prepared. A thin-film layer is formed on an outer surface of the protruded pattern of the stamp. The stamp having the thin-film layer contact with the adhesive layer is pressed to selectively transfer the thin-film layer of the protruded pattern to the adhesive layer. Ultraviolet rays (UV) are irradiated to cure the adhesive layer. The stamp is removed.
