Abstract: An apparatus for removing a photoresist layer from at least one alignment mark of a wafer is provided. The apparatus includes a holder, a solvent dispenser, and a suction unit. The holder is used to support the wafer, wherein the alignment mark is formed in a peripheral region of the wafer. The solvent dispenser is used to spray a solvent onto the photoresist layer on the alignment mark of the wafer to generate a dissolved photoresist layer. The suction unit is used to remove the dissolved photoresist layer and the solvent from the wafer through exhausting.

Abstract: With the waste container washing system described herein, the waste container can be moved into a washing compartment of the washing vehicle for washing thereof; in a first washing phase, the waste container can be exposed to a plurality of water jets of grey water pumped from a grey water reservoir; and in a second washing phase, the waste container can be exposed to a plurality of clean water pumped from a clean water reservoir. The water used in the first and/or second washing phase can be collected and stored in the grey water reservoir. Other improvements, such as a double-action pump for the two phases, a filtering system for grey water, a container movement system and path, and methods are also described.

Abstract: The plug is proposed for insertion into a hollow core of a roller cover to keep water from traveling through the hollow core, the plug comprising a body sized and configured to be received in the hollow core, and the body incorporating a peripheral lip thereon to keep the plug from being pushed into the hollow core by water pressure applied thereagainst.

Abstract: A produce washer includes a holder to position a single piece of produce and a nozzle disposed at a horizontal distance adjacent to the holder. When the produce is a cored lettuce head, the cored lettuce head is positioned in the holder with the cored portion facing the nozzle disposed across the horizontal distance. When the cored lettuce head is positioned in the holder, the nozzle directs a stream of cleansing liquid across the horizontal distance into the cored portion.

Abstract: A device for or in a garbage truck, particularly a vehicle for receiving and transporting so-called biological or organic garbage, includes tilting arrangements at the end of the vehicle for tilting a can containing garbage upwardly for emptying the can and for tilting the can backwardly into its initial position after the can has been emptied. The garbage dropped into the hold of the vehicle and the emptied can are sprayed with a disinfecting agent for treating the garbage and cleaning the can. The spraying device includes a spray nozzle which is movable between a first spray position for spraying in the direction of the garbage in the hold of the garbage truck and a second spray position for spraying in a second spray direction in which the spray jet is directed into the interior of the can which is in its upwardly tilted position.

Abstract: An agitator of washing machine has a washing shaft installed on a lower portion of a washing tub and extending upward to a bottom of the washing tub to be installed rotatively. A driving cam is installed on the washing shaft to rotate integrally with the washing shaft. A driven cam is installed around the washing shaft and contacts a surface of the driving cam to be driven by rotation of the driving cam. A moving bar of which one end contacts an outer surface of the driven cam and the other end extends upward into the washing tub through a hole formed on the bottom of the washing tub is provided such that the other end of the moving bar moves rotatively in the washing tub by rotation of the driven cam. A plate for forming rotating water flows which is formed in the other end of the moving bar moves rotatively integrally with the moving bar, thereby forming the rotating water flow flows in the washing tub. And, an elastic means tightly pushes the one end of the moving bar onto the surface of the driven cam.

Abstract: A method of forming a coating film, in which the coating film is formed by supplying a coating liquid onto a surface of a substrate, while the substrate housed in a processing vessel is rotated together with the processing vessel, includes the steps of coating the surface of the substrate with a solvent, supplying the coating liquid to the substrate, rotating the substrate and the processing vessel at a first rotation speed to diffuse the coating liquid on the surface of the substrate, closing the processing vessel with a lid to seal the substrate in the processing vessel, and rotating the processing vessel with the lid and the substrate at a second rotation speed to uniform a film thickness of the coating film.

Abstract: A washing machine with sub-pulsators is disclosed. A pulsator for generating vortical water flow is installed at a bottom of a washing tub, and many sub-pulsators are mounted on an inner side wall of the washing tub. Many ducts for forming passages in a vertical direction are provided in the side wall of the washing tub. When the pulsator is rotated, washing water flows in the ducts by the centrifugal force thereof and moves up along the ducts. The sub-pulsator is rotated by the washing water flowing in the ducts. Thus, a complex water flow is generated by the pulsator and the sub-pulsator, so the washing effect is improved and the twisting and tangling of the laundry is diminished.

Abstract: It is known to wash dispersion noodles in a `batchwise` fashion in which the noodles are retained in a kettle or kettle and water is sprayed onto the surface of the noodles. Agitation is achieved by bubbling air into the kettle from the bottom. Described herein is a method and apparatus for continuously washing dispersion noodles. The apparatus includes continuous pipe work in which the noodles are washed, the pipe work including at least one separating device (10) for separating the noodles from the water in which they have been washed. The device (10) comprises a housing (12) having an inlet (14) and an outlet (16). A separating element (22) is located in the housing (12) between the inlet (14) and the outlet (16) and is surrounded by a collection chamber (24), the element (22) comprising a tube of mesh material through which water passes into the collection chamber (24) and which is then drained off through drain (32).

Abstract: A dirty swimming pool filter is journaled for rotation about a vertical array of nozzles and spun about a vertical axis by the action of the spray. The rotation can be fast enough that centrifugal forces aid in the cleaning operation by sloughing dirt off the outside of the filter. One version of the apparatus includes a second vertical array of nozzles external to the filter and directing a spray against the outer face of the filter, which aids in sloughing dirt off it. This second array is rotatable about its own vertical axis and can be used to control the rate of rotation of the filter being cleaned. A sealed bearing is provided at the base of the filter to allow free rotation about the first vertical array of nozzles.

Abstract: The invention relates to a compact glasswasher having wash and rinse tanks and a circular glass conveyor located thereabove, rotation of the conveyor controlling emptying and re-filling of the rinse tank.
