Abstract: The treatment, for example the cleaning of holes or recesses in workpieces, is problematic when the holes or recesses have an opening width of below 0.5 mm, and especially when the latter do not penetrate the workpiece (blind bores). In known methods, gas bubbles adhering to the side-walls of holes of this type cannot be removed or liquids situated within the holes cannot be effectively exchanged. With the method according to the invention an effective exchange of the liquid contained in the holes and situated outwith the holes is made possible. For this purpose the liquid treatment means is sprayed as a jet into the holes, said jet having a diameter which is smaller than that of the holes. Furthermore, a device is described for carrying out this method which is characterised by a nozzle with one or several nozzle discharge openings with a diameter below 0.

Abstract: An overall washing operation for a horizontal axis washing machine includes at least one washing cycle and numerous rinse and spin cycles, with at least a portion of one of the rinse cycles being performed at an increased rotational speed for the spinner while the rinse water level is relatively high in order to establish a flush tumble cycle portion. With this arrangement, rinse water will be caused to flow from an outer tub of the machine through a frontal gap defined between an inner tub or spinner and the outer tub, as well as throughout a sealing boot extending between the outer tub and a front cabinet panel of the machine. This water flow and tumbling pattern causes items which have become lodged in the gap and boot areas to be flushed back into the spinner. Preferably, this flush tumble cycle portion is followed by a drain operation and a final spin cycle.

Abstract: A liquified gas dry-cleaning machine having a cleaning vessel with a chamber for containing a wash bath and items to be cleaned and a removable door for sealing the cleaning chamber during a dry-cleaning operation. The dry-cleaning machine has a door opening and closing apparatus which includes a pivot frame for moving the door outwardly from the cleaning vessel in an arced path of movement, and a slide for lowering the door on the pivot frame in a linear path of movement to a position below the level of the cleaning vessel. Reverse movement of the pivot frame thereupon positions the door in a tucked stored position at the same axial location with respect to the cleaning vessel as when the door is closed so as not to impede access to the cleaning chamber nor increase the axial reach of an operator necessary for removing items from the chamber.

Abstract: An agitator for a clothes washer having radially extending vanes and a slide member between the vanes. Vanes extend from the barrel portion of the agitator toward the outer perimeter of the skirt. The vanes have a base toward the barrel and a tip toward the outer perimeter of the skirt. The vanes have a right and a left side with each side having multiple planar faces for maximizing tip deflection. The pivot point, or connection point, of the base to the agitator has been lowered by connecting it to the center ring area of the skirt. Thus, vane breakage is reduced without decreasing washability. Slide members having a downward slope extend from the agitator barrel to the skirt at a slope less steep than the center ring area, but more steep than the slope of the skirt. These members move clothes from the barrel outward toward the perimeter of the skirt.

Abstract: A method for the wet treatment of a semiconductor wafer comprised of subjecting a semiconductor wafer to chemicals treatment, rinsing with pure water and drying by direct transfer of the wafer to an atmosphere of a vapor containing an alcohol, wherein the semiconductor wafer is treated with a solution containing a semiconductive particle-removing agent during the interval between the steps of the chemicals treatment and the drying. The semiconductive particle-removing agent is one which is able to control the zeta potential of the particles to prevent the deposition of the particles. Alternatively, semiconductive colloid coagulants may be used which inhibit the formation of the particles by coagulation of semiconductive colloids. Thus, deposition of particles on a wet-treated semiconductor wafer is prevented.

Abstract: A semiconductor workpiece cleaning apparatus comprises a cleaning means of a semiconductor workpiece by use of cleaning liquid, charging means of drying liquid, and discharging means of the cleaning liquid. The cleaning means cleans the workpiece by spraying chemical liquid and/or pure water in a chamber, and/or by immersing the workpiece in the chemical liquid and/or pure water. The charging means takes in drying chemical liquid or vapor into contact with the processing chemical liquid or pure water in which the semiconductor workpiece is immersed. The discharging means discharges the processing chemical liquid or pure water interfaced by the processing chemical liquid or pure water.

Abstract: A carbon dioxide dry cleaning system features a pair of liquid carbon dioxide storage tanks in communication with a compressor. A sealed cleaning chamber contains the objects being dry cleaned. By selectively pressurizing the storage tanks with the compressor, liquid carbon dioxide is made to flow to the cleaning chamber through cleaning nozzles so as to provide agitation of the objects being dry cleaned. Liquid carbon dioxide displaced from the cleaning chamber returns to the storage tanks. A still is disposed within one of the storage tanks and receives soiled liquid carbon dioxide as it is returned from the chamber. The pressure in the storage tank causes the soiled liquid carbon dioxide in the still to boil off. The gas is communicated to a third tank. The third tank may be used to initially pressurize the cleaning chamber. The system also includes a dispenser for the injecting solvent additives into the liquid carbon dioxide.

Abstract: A method and apparatus for washing cloth items in an automatic washer is provided wherein the automatic washer includes a wash basket defining a wash chamber and an impeller located within the bottom of the wash chamber. The method includes loading cloth items into the wash chamber and then supplying a quantity of wash liquid into the wash chamber sufficient to moisten the cloth items but insufficient to cause the cloth items to lose frictional engagement with the impeller as the impeller oscillates. The impeller is oscillated to apply a drag force to the cloth items in contact with the impeller such that the cloth items in contact with the impeller move angularly along an arc-like path. Angular movement of the cloth items disposed along the bottom of the wash chamber beyond the outer periphery of the impeller is impeded such that relative angular motion is created between the cloth items disposed along the periphery of the impeller and the cloth items disposed immediately above the impeller.
