Abstract: A DLP projector includes a light source generating white light beams, a color wheel separating the white light beams into three colored light beams, an integration rod rendering the colored light beams uniform, a projection lens, a DMD, a light-shade and a light-absorbing member. When a light beam on a first path is in use, a micro mirror of the DMD reflects the light beam on the first path to follow a second path towards the projection lens. Otherwise, the micro mirror reflects the light beam on the first path to follow a third, fourth and fifth path out of the projection lens. The light-shade is positioned in a light path of the light beam out of the projection lens. The light-absorbing member is under the light-shade and absorbs the light beam on the fifth path, the light beam on a sixth and a seventh path reflected by the light-shade.

Abstract: A rewritable phase change optical recording medium includes a substrate, a dielectric layer deposited on a surface of the substrate, and an optical recording layer deposited on the dielectric layer, wherein the dielectric layer may be omitted. The optical recording layer contains a composition of GexSb100-x-y-zMyEz, wherein 0.5?x?14.5; 0.5?y?14.5; 0?z?14.5; and M and E are different and are selected from the group consisting of Te, Cr, V, Ti, Ag, Sn, Si, Bi, Se, Al, Au, Ni, Fe, Cu, Mn, O, Ga, Cd, In, Pb and Hf, wherein M is not Te, when x is zero; and E is not Sn, when M is Te. The optical recording composition has a small crystal grain, a high ratio of reflectivity of the amorphous phase to that of the crystalline phase thereof, and a high crystallization rate, so that a blue light laser can be used to write/erase the recording medium.

Abstract: A high-temperature electrochemical etching apparatus containing a workpiece holder, which contains a first base plate and a second base plate to be joined together by screws, the first base plate having a recess on the front face thereof for receiving and retaining the workpiece, and both the first and second plates having a through hole to receive a contact electrode, which is electrically connected to a conductor wire. The second base plate has a protective wire sleeve fixedly inserted therein to allow the conductor wire to conduct electricity to the workpiece in a protectively sealed manner. A memory alloy coil and a buffer spring are provided between the contact electrode and the conductor wire in such a manner that the contact electrode is in a normally removed position from the workpiece until during high-temperature electrochemical etching operations, at which time, the memory alloy coil will expand thereby allowing electric voltage to be transferred to the workpiece.
