Abstract: An improved structure of the spray gun holder, which mainly comprises a baseplate, a brace, several crotches and a ring support, may hold more than two spray guns at one time, be adaptive to paint cup of various depths and be knocked down into parts at any time. Height of the ring support may be adjusted according to depth of the paint cup so as to meet different models of the spray gun that have particular paint cup. To have easy storage and cost reduction of packing and transportation, the spray gun holder of the present invention can be knocked down and have minimized packing dimensions.

Abstract: The present invention discloses a method for forming a stacked capacitor DRAM cell by first forming polysilicon plugs in a thick oxide layer deposited on a pre-processed semiconductor wafer, a polysilicon layer, a dielectric layer and a polysilicon layer are then sequentially deposited on top of the polysilicon plugs for making electrical contact with the silicon substrate such that a crown-shaped stacked capacitor can be formed on top of a transistor of the DRAM cell and chip real estate can be saved.

Abstract: In the filtration cycle, a fluid such as water containing suspended solid waste matter is treated with a coagulating agent and gravity-fed through a plurality of individual filter cells, or modules, containing a particulate, coarse, granular filter media. Backwashing is effected by injecting water into the filter media at the bottom center of the cell, causing the filter media to well upwardly and to form on the surface a series of polarly oriented ridges and troughs, the troughs serving to guide "mudballs" and coagulant particles on the media into an inlet port connected to the injector pipe where the high pressure water breaks up the mudballs into manageable particle sizes and scours the media. Solid particles suspended in the water overlying the media are drawn off through a backwash overflow and are fed into a clarifier where separation is effected and clarified water is provided for re-injection into the media.
