Abstract: A refrigerator may include a storage compartment, an inner door which comprises an opening having a size corresponding to a size of the storage compartment, a plurality of door guards, and an outer door which open and close the storage compartment, wherein the inner door comprises a control unit may control an internal environment of the storage compartment.

Abstract: The present invention is a thin film patch to be attached to the skin and used for skin treatment or skin care. In particular, a water-soluble polymer compound is formed by means of melt spinning, melt blowing or electrospinning, into a water-soluble non-woven fabric of which the average diameter of fiber is 5 ?m or less. The water-soluble non-woven fabric is coated with a coating agent comprising an active ingredient with a skin treatment or skin care effect; therefore, a thin film having the total thickness of 50 ?m and the basis weight of 20 gsm or less is formed, wherein the water-soluble non-woven fabric has an electrically conductive material deposited thereon to have electrical conductivity and is connected to an electrode so that a current can be applied thereto.

Abstract: A mold includes a lower mold onto which flat glass is loaded, the lower mold being formed so that an upper portion thereof has a concave curved surface shape to load the flat glass; and an upper mold disposed above the lower mold to press the flat glass together with the lower mold, the upper mold being formed so that a lower portion thereof has a convex curved surface shape to press the flat glass. The lower mold is manufactured by reflecting an amount of dimensional change according to a shape change before and after molding of the flat glass and an amount of dimensional change due to thermal expansion of the lower mold and flat glass between a room temperature and a molding temperature.

Abstract: Disclosed herein is a glass manufacturing method and a mold for glass manufacture. The glass manufacturing method includes cutting raw flat glass having a large size into a suitable size for a product, inserting the flat glass into a mold formed with a cavity having a curved surface shape to mold the flat glass so that a front face portion has a concave curved surface shape and a back face portion has a convex curved surface shape, processing the back face portion having the convex curved surface shape into a flat surface shape by a grinding process, and processing the back face portion processed into the flat surface shape to have a specular surface through a polishing process.
