摘要： A wet laser cleaning apparatus includes a machine base, a laser cleaning module, a shielding housing and a filtering device. A base material is placed in a reservoir of the machine base, into which a liquid is introduced through the filtering device. A control module drives first parallel axial track groups, a second parallel axial track group and a vertical axial track group to move an optical fiber laser knife device of the laser cleaning module to irradiate and clean the base material. A height sensor device and an orientation sensor device sense a position and a height of an object, so that the optical fiber laser knife device can automatically focus on the base material. Dusts produced after the optical fiber laser knife device has irradiated the base material are stored in the liquid, and the filtering device filters the dusts from the liquid.

摘要： An apparatus includes a substrate stage configured to secure a substrate thereon and a motion mechanism configured to rotate the substrate stage. The substrate stage includes a plurality of holding pins for holding an edge of the substrate. Rotating the substrate stage causes a chemical solution dispensed on an upper surface of the substrate to spread outwardly toward the edge of the substrate. At least one of the plurality of holding pins includes at least one opening or at least one tapered side surface, or both, for guiding the chemical solution to flow off the substrate.

摘要： The present invention relates to systems and methods for cleaning materials, such as flooring and upholstery. In some cases, the systems and methods use an electrolytic cell to electrolyze a solution comprising sodium carbonate, sodium bicarbonate, sodium acetate, sodium percarbonate, potassium carbonate, potassium bicarbonate, and/or any other suitable chemical to generate electrolyzed alkaline water and/or electrolyzed oxidizing water. In some cases, the cell comprises a recirculation loop that recirculates anolyte through an anode compartment of the cell. In some cases, the cell further comprises a senor and a processor, where the processor is configured to automatically change an operation of the cell, based on a reading from the sensor. In some cases, a fluid flows past a magnet before entering the cell. In some additional cases, fluid from the cell is conditioned by being split into multiple conduits that run in proximity to each other. Additional implementations are described.

摘要： An ultrasonic cleaning apparatus capable of cleaning large-sized objects includes: a casing having a bottom surface that forms a tilted surface to oppose the object to be cleaned and having an ultrasonic transducer provided at an inner lower surface; a cleaning liquid supply device configured to supply cleaning liquid to a casing bottom surface; and a flow-speed accelerator that ejects the cleaning liquid by accelerating the flow speed of the cleaning liquid from the cleaning liquid supply device. The casing is formed by a main body including an upper plate, a projected part attached to a lower part of the upper plate, an outer lateral face extended from the projected part in a downward direction, and the bottom surface connected integrally at a lower end part of the outer lateral face. The bottom surface is formed to be tilted at a prescribed angle with respect to a horizontal plane.

摘要： A soil-based coupon having an electronically readable verification code printed thereon is used for verification of soil removal by a cleaning process. The coupon includes a soil overlay covering the verification code. The verification code is at least partially revealed by removal of all or part of the soil overlay during the cleaning process. If the data encoded in the verification code can be correctly decoded after completion of the cleaning process, the cleaning process can be verified. The soil overlay can be designed to match the application. The coupons may be used in a cleaning process verification procedure in which one or more computing devices analyze images of the verification codes to determine whether or not cleaning processes can be verified.

摘要： Provided is a method for cleaning a rolling bearing and a rolling bearing cleaning device capable of cleaning a rolling bearing easily in a short time. The method for cleaning a rolling bearing including a plurality of rolling elements and a race provided with a race groove along which the rolling elements roll involves arranging a cleaning liquid in a pressurized state on one side in an axial direction of the rolling bearing across a whole circumference thereof with respect to a gap between the rolling elements and the race groove, and cleaning the rolling bearing by passing the cleaning liquid through the gap from one side in the axial direction toward the gap on the other side thereof.

摘要： A cleaning system for a meat-packing plant includes a tank with a potassium-based cleaner disposed in the tank. A track has a gambrel disposed on the track. The track includes a dip over the tank to dip the gambrel into the potassium-based cleaner as the gambrel moves along the track. A processed animal carcass is removed from the gambrel prior to the gambrel being dipped into the potassium-based cleaner. A fresh animal carcass is disposed on the gambrel after the gambrel is dipped into the potassium-based cleaner.
