Abstract: Provided is a multi-touch screen device that may calculate x and y orthogonal coordinates of a touch area even if a receiving/transmitting element is arranged on only one of the x-axis and the y-axis. The receiving/transmitting element is not arranged on both the x-axis and the y-axis so that an infrared ray scans a touch area in a matrix configuration, but an infrared receiving/transmitting element is arranged on only one of the x-axis and y-axis so that one receiving module sequentially scans the touch area using a right-angle scan measurement signal and an oblique-angle scan measurement signal. The multi-touch screen device may decrease the number of receiving/transmitting elements for use and solve a ghost image problem that occurs in a multi-touch operation that uses infrared rays.

Abstract: The present invention provides a fuel cell separator with a gasket and a method for manufacturing the same, which can prevent corrosion of the separator and improve corrosion resistance of the separator. In particular, the present invention provides a fuel cell separator with a gasket and a method for manufacturing the same, in which an adhesive is coated on the entire or partial surface of the separator, preferably by screen printing. A process of integrally molding a gasket to the separator is then performed such that the edges of the separator are not exposed to the outside after the injection molding process but, rather, are coated with the resin adhesive. The present invention thereby prevents corrosion of the separator, improves corrosion resistance of the separator, and prevents formation of burrs during the injection molding process.
