Abstract: A transport apparatus includes a transport rail extending along a predetermined path, a transport vehicle configured to be movable along the transport rail to transport a material, and a brake unit mounted on the transport vehicle to be adjacent to the transport rail and configured to apply an eddy current braking force to the transport vehicle.

Abstract: A liquid crystal display (LCD) panel transferring system including a panel transferring apparatus that takes out and transfers a LCD panel formed at a surface of a substrate; a camera installed at the panel transferring apparatus that captures an image of the LCD panel; and a controlling unit that aligns the LCD panel with the panel transferring apparatus based on an image captured using the camera. The panel transferring apparatus includes a main body; a plurality of suction holes formed at the main body that fix an LCD panel to the main body; and a pin formed at the peripheral area of the main body that applies an impact to a dummy region to separate the LCD panel from the substrate.

Abstract: To prevent inflow of condensed water to an exhaust gas recirculation (EGR) valve, an exhaust gas recirculation system includes a first gas passage, an exhaust gas recirculation valve connected to the first gas passage and selectively opening/closing the first gas passage, an exhaust gas passage disposed in the exhaust gas recirculation valve, and a second gas passage connecting the exhaust gas passage to an air-fuel mixture passage. The exhaust gas passage is tilted at an obtuse angle with respect to the second gas passage. The angle may be less than about 170°, and in some embodiments the angle is about 165°.

Abstract: A multi-step membrane separation process whereby the natural polymer .alpha.-chitosan extracted from the shell of crustaceans, etc. can be simply separated and purified into low molecular weight chitosan or oligosaccharide chitosan in a high yield. A chitosan mixture of various molecular weights is reacted with an acid in the presence of enzyme while applying an ultrasonic treatment to the mixture and then, added with pure water to give an aqueous solution having a chitosan concentration of 1 to 50%. It is subjected to a continuous membrane filtration under a pressure and further to a second fractionation and separation technique employing a proper membrane according to a desired molecular weight cut-off, at least one time.
