Abstract: The present invention relates to a composite separation membrane including a graphene oxide coating layer. The composite separation membrane of the present invention has both high carbon dioxide permeability and high selectivity for carbon dioxide over nitrogen, hydrogen or methane gas, is free of surface defects, and exhibits remarkably increased selectivity for carbon dioxide over other gases (hydrogen, nitrogen, methane, etc.) without any change in carbon dioxide permeability, particularly even when exposed to water. Due to these advantages, the composite separation membrane of the present invention can be applied to industrial fields involving carbon dioxide separation and recovery processes. The present invention also relates to a method for manufacturing the composite separation membrane.

Due to these advantages, the composite separation membrane of the present invention can be applied to industrial fields involving carbon dioxide separation and recovery processes. The present invention also relates to a method for manufacturing the composite separation membrane.

Abstract: Methods and apparatus are provided for controlling a mobile terminal including a touch screen supporting a multi-touch input. The method includes: determining a number of one or more points inputted as a first touch input on the touch screen; when the number is 3, determining the first touch input as a three-point input; determining a size of a largest internal angle of a triangle generated by connecting points of the three-point input on the touch screen; displaying one of a linear tool and a circular tool based on a size of the largest internal angle of the triangle; receiving a second touch input; generating a line corresponding to the second touch input by interworking with one of the linear tool and the circular tool; and displaying the generated line on the touch screen.

Abstract: An organic layer deposition apparatus includes a conveyer unit and a deposition unit that has one or more organic layer deposition assemblies configured to deposit an organic layer on a moving substrate. The conveyer unit includes a moving unit configured to move a substrate fixed thereto, a first conveyer unit configured to move the moving unit in a first direction during which an organic material is deposited on the substrate fixed to the moving unit, and a second conveyer unit configured to move the moving unit in a second direction opposite to the first direction after deposition is completed and the substrate is separated from the moving unit. The first conveyer unit and the second conveyer unit are configured to move through the deposition unit.

Abstract: Disclosed is a technique, in which when driving chips are used in which control units are respectively merged in driving devices, all modes of the other driving chips are simultaneously converted into a fail safe mode when one driving chip detects a non-signal state. A circuit for controlling a non-signal of a flat panel display device includes a plurality of driving chips. When detecting a non-signal state that the normal signal (LVDS) is not inputted from an outside, each of the plurality of driving chips simultaneously changes potentials of non-signal detection pads of its own driving chip and another driving chip so that all the driving chips are operated in the fail safe mode.
