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: An innovative “helical structure” for connection of the spray equipment and the paint cup mainly comprises an internal thread connector integrally formed on top of a spray gun and a corresponding external thread connector integrally formed on the connecting section extended from bottom of a paint cup. Connection of the spray gun and the paint cup is made by screwing the external thread connector into the internal thread connector. The characteristic lies in: the multiline threads on the internal thread connector correspond to the single threads on the external thread connector, and both threads share identical thread pitches. The combination of the single thread and multiline threads grants a fast and tight connection of the spray gun and the paint cup. Besides, the single thread is automated adjustable and assures a non-deadlock connection even if it is inclined while being inserted into an open end of the double thread.

Abstract: A loadport for a semiconductor fabrication machine that is equipped with an automatic height adjustment means and a method for operating the loadport are described. The loadport consists of a moveable platform for carrying a wafer cassette thereon and supported by at least two support members capable of moving the platform in an up-and-down direction. A distance sensor is mounted on a bottom surface of the platform for measuring a height of the platform. A process controller is used to receive a first signal from the distance sensor, comparing to a pre-stored datum and then sending a second signal to the at least two support members to move the platform until the first signal equals the pre-stored datum.

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: An improved spray paint gun, comprises a regulating port in the intersection between the inlet channel, main spray channel and side spray channel. The regulating port is provided with a regulating ring and the regulating is being provided with first, second and third apertures in the position corresponding to each of the inlet channel, the main opening and the side opening respectively. A regulating element is screwed onto the regulating port by a connecting element disposed at the regulating element. The connecting element is provided with a movable regulating rod which may insert into the regulating port. When the regulating rod moves downward to close the side spray channel completely, the thickness of the regulating port can be increased by the provision of the regulating ring to regulate the air stream pressure flows therethrough. Accordingly, the air stream pressure inside the main spray channel can meet the requirements of HVLP (high volume low pressure).

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.
