20110089031	Sputtering System with Normal Target and Slant Targets on the Side - A sputtering system aimed for sputtering workpieces that have non-planar surfaces, such as concaves, pillars, and steps of a case of a laptop. The sputtering system comprises a sputtering chamber including a carrier, a first sputtering source, and a second sputtering source. The first sputtering source is located over the carrier main to sputter planar portion of the workpiece. The second sputtering source is inclined at an angle so as to sputter the vertical portion of the workpiece.	04-21-2011

20090245780	Shutter device - A shutter device comprises a base, two electromagnetic valves, two blades, and a cover plate. A first light hole is formed in the center of base. The electromagnetic valve comprises a magnetic core, a coil unit, and a magnetic part. The magnetic cores and coil units are on the base, being axially symmetrical at the periphery of first light hole of the base. The blades join with the corresponding magnetic parts of the electromagnetic valves, in which each of the blades may travel between first and second positions at a degree of freedom to open or shut the first light hole through which rays of light pass. The cover plate is assembled onto the base and provided with a second light hole corresponding to the first light hole. The two magnetic cores are axially symmetrical on the base and lie at the periphery of first light hole.	10-01-2009
