Abstract: An apparatus for manufacturing a display device includes a gas exhaust unit and a gas spray unit. The gas exhaust unit includes first and second sidewalls disposed side by side along a first direction, and an upper plate disposed on the first and second sidewalls, a first partition disposed between the first and second sidewalls and extending away from a lower surface of the upper plate in a second direction. The gas spray unit includes first and second spray portions spraying first and second gases in the second direction. The first partition includes first and second surfaces, a third surface connecting the first surface to the second surface, first and second horizontal openings formed at the first and second surfaces, a first vertical opening formed at the third surface, and a first sub exhaust path connecting the first and second horizontal openings, and the first vertical opening with each other.

Abstract: The present invention relates to an apparatus and method for encoding and decoding an image by skip encoding. The image-encoding method by skip encoding, which performs intra-prediction, comprises: performing a filtering operation on the signal which is reconstructed prior to an encoding object signal in an encoding object image; using the filtered reconstructed signal to generate a prediction signal for the encoding object signal; setting the generated prediction signal as a reconstruction signal for the encoding object signal; and not encoding the residual signal which can be generated on the basis of the difference between the encoding object signal and the prediction signal, thereby performing skip encoding on the encoding object signal.

Abstract: An automatic tennis ball supply device, includes: a spring for transmitting the power via its elasticity; a first shaft which is joined to part "b" which is the first part of a steel band of the spring; a handle for winding the spring; a first gear which rotates in the same direction as the first shaft; a second gear which rotates to the left when the wound spring runs down; a latch for disengaging the first and second gears from each other when the spring is wound, and for engaging the first and second gears with each other when the wound spring runs down; a third gear which rotates to the right, when the second gear rotates to the left; a second shaft which rotates in the same direction as the rotating third gear; a rotative speed control unit for controlling a rotative speed of the second shaft; a ball pick up unit for picking up and conveying one of the plural tennis balls in a container; a ball guide unit for guiding the tennis ball to outside.
