20100024720 | COATING APPARATUS FOR COATING A BUILDING BOARD - A coating apparatus for coating an entire surface of a building board without forming uncoated area, while conveying the building board, having: an application device for applying a coating material to the surface of the building board; a removal device for removing an excess coating material applied to the surface of the building board and forming a coating liquid film; and a pressure device for blowing air to the coating liquid film on the surface of the building board, wherein the pressure device is provided in a step posterior to a step that uses the removal device and has an air outlet which is wider than the building board and which covers the surface of the building board, and wherein the surface of the building board is applied with pressure of the atmospheric pressure or higher, while the building board is conveyed from the removable device to the pressure device. | 02-04-2010 |
20100031879 | GAS WIPING APPARATUS HAVING MULTIPLE NOZZLES - A gas wiping apparatus is a type of equipment for coating a molten metal onto a steel strip, in which the molten metal solution deposited on the steel strip is wiped to adjust a coating thickness. The gas wiping apparatus includes a body containing a high pressure gas and a multiple nozzle unit disposed at the body to eject the high pressure gas onto a surface of a moving coated steel strip. The surface of the coated steel strip passing through a hot dipping bath filled with the molten metal is wiped by a high speed gas jet. Here, the molten metal is prevented from splashing even at a high-speed and the steel strip can be adjusted in the coating thickness stably and uniformly. | 02-11-2010 |
20100175615 | APPARATUS FOR PRODUCING HOT-DIP METAL COATED STEEL STRIP - An apparatus for producing a hot-dip metal coated steel strip configured to control the thickness of a coating metal by blowing a gas from wiping nozzles to a steel strip continuously drawn from a coating bath, the wiping nozzles being arranged above the coating bath and facing the respective surfaces of the steel strip, and including rectifying plates arranged on the respective sides of the steel strip located above submersed support rolls and below the surface of a molten metal while not being in contact with the steel strip and the submersed support rolls, each of the rectifying plates having a roll-covering portion and a steel-strip-facing portion, each of the roll-covering portions being arranged to cover ΒΌ or more of the periphery of a corresponding one of the submersed support rolls near to the molten metal surface, each of the steel-strip-facing portions arranged above a corresponding one of the submersed support rolls and facing the steel strip, and the steel-strip-facing portions of the rectifying plates being connected to the respective steel-strip-side ends of the roll-covering portions. | 07-15-2010 |
20100224120 | GAS WIPING APPARATUS - In a gas wiping apparatus which blows gas through a wiping nozzle onto front and rear surfaces of a steel plate going out from a molten metal coating pot and running upward and which thereby controls a deposit mass, the wiping nozzle is separated into upper and lower lips, blocking faces partially closing a gas supply channel are formed in the upper and lower lips at vertically different positions on the opposite sides from each other in a gas outlet width direction, and the upper and lower lips are provided in such a manner as to be movable in a width direction of the steel plate. | 09-09-2010 |
20100224121 | APPARATUS FOR THE COATING OF A SUBSTRATE - The invention relates to an apparatus for the coating of a substrate, in particular of a circuit board, with a material application device for applying a coating material and with a gas supplying device for the supply of a gaseous medium, the material application device having an inner tubular element, the gas supply device having an outer tubular element which is arranged coaxially to the inner tubular element and surrounds the latter, so as to form between the outer and the inner tubular element a gas supply duct which has an annular orifice at one end, the supply duct being configured so that the gaseous medium flows out, parallel to the coating material, through the annular orifice, in order, when it impinges on the substrate, to displace the applied coating material and thereby distribute it over the area. The apparatus is distinguished in that the material application device has a jet valve which, in a first operating mode, carries out a jetted supply of material into the inner tubular element. | 09-09-2010 |
20120006258 | HYDROGEN RADICAL GENERATOR - A method of reducing contamination generated by a hydrogen radical generator and deposited on an optical element of a lithographic apparatus includes passing molecular hydrogen over a first part of a metal filament of the hydrogen radical generator, the first part including a metal-oxide, when the temperature of the first part of the metal filament is at a reduction temperature less than or equal to an evaporation temperature of the metal-oxide. | 01-12-2012 |
20130239884 | GAS WIPING DEVICE - A gas wiping device for preventing splash on a steel band including a box-shaped body enclosing the steel band and gas wiping nozzles is provided with a plating bath for storing molten metal, and a box-shaped body placed above the plating bath. The box-shaped body is provided, in the interior, with gas wiping nozzles disposed facing one another on the respective tubular members so as to sandwich a band-shaped body. Gas wiping nozzle is provided with a first spraying unit capable of spraying gas to the steel band, and a second spraying unit and a third spraying unit capable of spraying gas towards the direction of gas wiping nozzle. Gas wiping nozzle is provided with a fourth spraying unit capable of spraying gas to the steel band, and a fifth spraying unit and a sixth spraying unit capable of spraying gas towards the direction of gas wiping nozzle. | 09-19-2013 |
20140202380 | WIPING DEVICE AND HOT DIP COATING APPARATUS USING THE SAME - A wiping device which blows a wiping gas toward a steel sheet from a pair of wiping nozzles disposed on both sides of the steel sheet so as to face sheet surfaces of the steel sheet, wherein the steel sheet is interposed between the pair of wiping nozzles and is pulled from a hot dip coating bath, the device includes a suctioning tube, wherein: the suctioning tube is disposed on both sides in a width direction of a section of the steel sheet, the section being positioned between the pair of wiping nozzles, so that the suctioning tube is in parallel to the steel sheet; the suctioning tube has a suctioning port that suctions an air; the suctioning port is disposed to face a side end surface of the steel sheet; a cross-sectional shape of the suctioning tube has the largest dimension thereof along a pulling direction of the steel sheet. | 07-24-2014 |
