Abstract: A display system for presenting multiple images from a single art object depending upon the observer's viewing angle comprising a housing, a protective cover, a distortion lens, an art object, a support means for securing a lighting system contained within the housing, and a cooling system and power source within the housing.

Abstract: A semiconductor manufacturing apparatus is described. That apparatus includes an ash chamber that has an ash chamber base, and a heating unit that is coupled to the ash chamber base. The heating unit applies heat to the ash chamber base to reduce deposition of residues onto ash chamber base surfaces, which could cause surface particle defects in a semiconductor device.

Abstract: A drumstick structure provides a structural outer body, preferably transparent, with a central hollow bore therein, into which a rod can be inserted as desired. The central portion is permanent, or removable which can be interchanged between drumsticks as desired. In the preferred embodiment, the inner portion is comprised of an elongated shaft which conforms to the configuration of the inner bore. An end cap seals off the inner bore securing the rod therein by providing a screw-on end portion. In the preferred embodiment the cap can be an enlarged rubberized tip to provide a tympani beater head. In an alternative embodiment, the inner portion is injected with an injection moldable plastic, the plastic then hardened to form a permanent but lighter inner portion so as to make the overall drumstick a desired weight. The drumstick would be of a plastic construction to provide greater strength.
