Abstract: A robot synchronization sealer discharge system is provided. The robot synchronization sealer discharge system is interlocked with a robot for a sealer work of a vehicle factory and includes: a sealer gun mounted on a robot and moving along an application path of a vehicle body to discharge a sealer and a communication unit for receiving a TCP speed of the sealer gun moving based on robot operation. A synchronization controller assigns a unique ID and a received TCP time to the TCP speed and generates a discharge instruction message recording the sealer discharge amount according to the TCP speed. A sealer controller adjusts a discharge of the sealer gun based on the discharge instruction message and feeds back the sealer time according to a discharge completion to the synchronization controller.

Abstract: The present invention relates to a method of preparing a photochromic film or plate comprising printing a photochromic substance in the unit of an independent spot on a part or the whole of a basic material and forming a protective layer on the basic material, on which the photochromic substance is coated, so as to protect the photochromic substance. According to the present invention, the photochromic substance is printed in the unit of an independent spot so that the printed unit spots are isolated from each other, thereby prolonging the life of the photochromic substance.

Abstract: Provided is a spin coating apparatus having a ring-shaped or polygonal auxiliary member for use in manufacture of a coated substrate via spin coating, wherein the auxiliary member is positioned adjacent to the side of a substrate for coating, within a range of a spaced distance of 0.03 to 0.8 mm and a range of a height deviation of less than 0.1 mm, upon mounting the substrate. When a surface of a substrate for coating is spin coated with a coating agent using the apparatus of the present invention, it is possible to eliminate or effectively reduce a ski-jump phenomenon at end portions of a coated substrate occurring when spin coating is performed, thereby resulting in uniform coating of a coating solution on the substrate, and it is also possible to effectively decrease contamination of the substrate for coating due to inflow or stay of the remaining coating agent.
