Abstract: In a substrate processing apparatus for forming thin layers on a substrate used for an organic light emitting diode, the apparatus includes a mask attaching chamber, a deposition chamber and a mask detaching chamber. The mask attaching chamber, the deposition chamber and the mask detaching chamber are provided with a transferring guide installed thereinside, and a substrate supporter for supporting the substrate moves along the transferring guide in or between the chambers. Thus, a time for processing the substrate and an area for the apparatus may be reduced. Also, the chambers are grouped in one or more, and a gate valve is installed between the grouped chambers for opening and closing a path between the grouped chambers. Accordingly, the chambers may be continuously maintained in a vacuum state when any one of the chambers is repaired.

Abstract: A wind power generating system that is a technology for converting wind energy to electrical energy is provided. The system blocks flow of air inside the impeller, so that a high speed jet pressure on an I.G.V. (inlet guide vane) is converted to a constant pressure between the blades disposed downstream of the flow which has passed through the inlet guide vane, thus generating a large amount of torque.

The component-based web application development framework used for creating a web page comprises a runtime engine for executing a method of a business object and returning a result of executing the method in response to a user's request; a script component for performing a preprocessing on a user input value before executing the method of the business object, performing a post-processing on the result of executing the method after executing the method of the business object, and dynamically arranging a user interface object; and a core component for initializing the framework and confirming whether the user's request can be processed in the framework.

Abstract: The present invention relates to an image quality evaluating device for using a color appearance model to evaluate image quality of a color area, and a method thereof. The image quality evaluating device realizes a color space corresponding to a color area by using information on color appearance, calculating a volume of the color space, and calculating clearness of the color area, viewing angle characteristics, gray level characteristics, and color differences in the color space.

Abstract: Provided are an apparatus and method for controlling a vertical axis wind power generation system that controls the rotation of guide vanes according to wind direction and speed, appropriately controls a direction of wind passing over an impeller, thereby maintaining a rotational speed generating the maximum power, maintains output power of a generator as rated power according to wind direction and speed, and stops the generator when a low or high wind speed outside a setting value range, an error in a structure, a fault in a braking unit, and/or a fault in guide vanes is detected.

Abstract: A slurry distribution system for supplying slurry used in the planarization process of a wafer surface by chemical reaction is provided with a movable supply line having an open end which is maintained at a constant depth below the surface of the slurry in the slurry tank. The movable supply line penetrates the top of the tank and is supported for vertical movement in an opening in the top of the tank. The other end of the movable supply line is located outside the tank and is connected to a main supply line which leads to CMP equipment. A pleated flexible tubing allows the movable supply line to move vertically relative to the main supply line and the top of the tank. A position-controlling mechanism keeps the open end of the movable supply line at a predetermined distance below the top surface of the slurry in the tank as the top surface rises and falls, by moving the movable supply line vertically in accordance with the changing amount of slurry inside the tank.
