The present invention relates to an apparatus for cleaning press rolls for electrodes, comprising two or more cleaning units provided with cleaning members having grains. According to the present invention, the apparatus for cleaning press rolls for electrodes comprises a plurality of, i.e., two or more, cleaning units, wherein the cleaning units respectively comprise cleaning members having grains with different directions, thus allowing a residual cleaning solution and contaminants to be effectively removed. In addition, when press rolls are cleaned using the apparatus for cleaning press rolls according to the present invention, an aqueous cleaning solution and an alcoholic cleaning solution, which have different properties, can be used together, and after cleaning, the cleaning solutions do not remain on the press rolls, and thus subsequently, secondary contamination of electrodes is prevented, and accordingly, when electrodes are manufactured, the occurrence of defects in the electrodes can be reduced.

The present invention relates to an electrode rolling roll cleaning apparatus for removing pollutants on an electrode rolling roll, the apparatus comprising: a cleaning part for cleaning a rolling roll by bringing the rolling roll into contact with a cleaning member; an air spraying part for spraying air onto the rolling roll; a heating part for applying heat to the rolling roll so as to dry the rolling roll; and a scraper part for mechanically removing a cleaning liquid and foreign substances attached to the rolling roll.

An apparatus on a vehicle comprises one or more sensors, one or more nozzles that output fluid to clean the respective one or more sensors, and a compressor that generates fluid such as compressed air. The compressor is in fluid communication with the one or more nozzles. The apparatus further comprises one or more processors, and a memory storing instructions that, when executed by the one or more processors, cause the system to determine a current velocity of the vehicle and control an operation of the compressor based on the current velocity of the vehicle.

A method for manufacturing a structure on a surface of a workpiece (1) is disclosed, the method having the following steps: applying a liquid base layer (2) onto the surface of the workpiece (1); spraying on at least one droplet (3) into the not yet congealed base layer (2), wherein the at least one droplet (3) at least partially, preferably completely, penetrates into the base layer (2); fixing the base layer (2); and at least partially removing the at least one droplet (3). Further, a second method having the following steps is disclosed: spraying on at least one droplet (3) onto the surface of the workpiece (1); applying a liquid base layer (2) onto the surface of the workpiece (1), wherein the base layer (2) flows around the at least one droplet (3) and preferably at least partially covers the at least one droplet (3); fixing the base layer (2); at least partially removing the at least one droplet (3). Finally, a device for performing the methods is disclosed.

A link chain cleaning and lubricating device, and lubricants for use therein.

Provided is an automatic mattress sterilization apparatus configured to sterilize a mattress, including a frame extending in one direction and on which the mattress is placed, a sterilization part coupled to an upper portion of the frame and having an inner space through which the mattress passes, and a moving part provided in the frame and configured to move the mattress placed on the frame, and the mattress is moved from one side of the sterilization part to the other side of the sterilization part via the inner space of the sterilization part by the moving part.

A substrate processing system for selectively etching a substrate includes a first chamber and a second chamber. A first gas delivery system supplies an inert gas species to the first chamber. A plasma generating system generates plasma including ions and metastable species in the first chamber. A gas distribution device removes the ions from the plasma, blocks ultraviolet (UV) light generated by the plasma and delivers the metastable species to the second chamber. A substrate support is arranged below the gas distribution device to support the substrate. A second gas delivery system delivers a reactive gas species to one of the gas distribution device or a volume located below the gas distribution device. The metastable species transfer energy to the reactive gas species to selectively etch one exposed material of the substrate more than at least one other exposed material of the substrate.

The present application discloses a cleaning method and a cleaning device. The cleaning method includes the following steps: dividing a cleaning device into at least two regions to control for the same cleaning mode; detecting a width of an object to be cleaned; and turning on the cleaning device of corresponding region according to the width of the object to be cleaned. The cleaning device includes a detection structure, a conveying structure, a washing structure, an air knife structure, and a control structure, where the washing structure is divided into at least two regions, and the air knife structure is also divided into at least two regions.

A coating method of a board for producing a concrete product and a board coated by the same are proposed. The coating method is advantageous in that the whole surface of a board can be rapidly coated and dried to prevent surface corrosion of the board and to prevent further corrosion on a damaged surface of the board, thus improving the durability of the board and the quality of the produced concrete products. The coating method includes: removing residues existing on an outer surface of the board by blowing high-pressure air to an upper surface and a lower surface of the board for producing a concrete product; coating by spraying coating liquid to the outer surface of the board from which the residues have been removed; and drying the coating liquid by blowing high-pressure air to the outer surface of the board.
