Abstract: A method for cleaning a closed-end cartridge filter begins by mounting a spindle assembly to one end of a cartridge filter. The spindle assembly is self-centered on the end of the cylindrically shaped cartridge filter by a three-point grip on the perimeter. A similar spindle assembly is attached to the other end of the cartridge filter such that its axis of rotation is the same as the axis of rotation for the first spindle assembly. The tip of one spindle assembly is rested on the ground while the tip of the other spindle assembly is held by a user's hand. A pressurized stream of air or water is directed at the cartridge filter with the user's other hand such that the stream causes the whole to rotate. The speed of rotation is brought high enough to fling debris from the filter and thus clean it.

Abstract: In a substrate bath that processes substrate wafers using megasonic energy, a tank that is provided with reflecting surfaces that direct the megasonic energy to those portions of the substrates that would otherwise be sonically shadowed by the cassette that supports the substrates. In one aspect, a pair of curved wall surfaces are formed within the tank, each extending from one side wall to the bottom wall in curvilinear fashion and oriented longitudinally, the paired curved wall surfaces being disposed in laterally spaced, enantiomorpic relationship. The curved surfaces are arranged so that a significant amount of the megasonic energy impinges at an angle less than the critical angle, so that the energy is reflected in a diverging field that intersects the substrates and strikes those portions of the substrates that are shadowed by the cassette structure. Thus the megasonic cleaning, (etching or processing of the substrate) process is improved significantly.

Abstract: A water filter includes a cartridge filter element mounted on a coaxial bearing so it can be spun. During normal operation, a pressure tank enclosure allows the outside of the cartridge filter element to be submerged. Filtered water is then collected by a filtered-water return inside the cartridge filter element. An air vent disposed in the pressure tank housing allows water to drain away before starting a cleaning cycle, and to bleed off trapped air before returning to normal operation. During cleaning, a flow of clean water is applied to the filtered-water drain. A wash drain in the bottom of the pressure tank enclosure allows used cleaning water to flow out. The reverse water flow through the filtered-water drain forces closed a flapper valve. This, in turn, causes a water spray jet manifold to fill under pressure and cleaning water sprays out from slightly offset nozzles directed at the cartridge filter element.
