  • Patent number: 8298341
    Abstract: A method is used for removing a metal contaminant deposited on a quartz member selected from the group consisting of a reaction tube, wafer boat, and heat-insulating cylinder of a vertical heat processing apparatus for a semiconductor process. The method includes obtaining the quartz member unattached to the vertical heat processing apparatus; then, performing diluted hydrofluoric acid cleaning of cleaning the quartz member by use of diluted hydrofluoric acid; then, performing first purified water cleaning of cleaning the quartz member by use of purified water; then, performing hydrochloric acid cleaning of cleaning the quartz member by use of hydrochloric acid; and then, performing second purified water cleaning of cleaning the quartz member by use of purified water.

  • Patent number: 8298347
    Abstract: A method of and apparatus for cleaning a surface, such as a wall of a waste boiler of a Kivcet furnace, are described. The invention comprises suspending a pair of spaced apart cables adjacent a surface to be cleaned, attaching ends of the rail to respective ones of the cables with equal lengths of cable between the rail and the roof, the rail being reversibly moveable up and down the surface. A carriage has a nozzle assembly, operative to emit a jet of water, with the carriage reversibly moveable along the rail. The rail is moved from one of a top and bottom of the surface to another of the top and bottom of the surface, and the carriage is moved from one side of the rail to another, cleaning the surface as it moves. The foregoing steps are repeated for each remaining uncleaned surface.

  • Patent number: 8298343
    Abstract: A method and apparatus for removing ice from overhead utility power lines which includes a tool having an extendable pole with an ice removing roller having an annular outer channel rotatably supported on the pole. The pole is extendable for enabling a user to place the roller over an ice-laden utility power line while standing on the ground, and then is movable along the power line by the workmen while standing on the ground or walking along a line parallel to the power line for removing ice from the line.

  • Patent number: 8298342
    Abstract: A dedusting device and method is disclosed for the dry or moist dedusting (i.e., cleaning, dusting, or removal of dirt, dust, or other debris) from components, e.g., of motor vehicles. An exemplary method may generally include positioning a dusting tool driven by a drive motor in a predetermined dusting position such that the tool contacts or touches the component, and determining a first operating variable of the drive motor of the dusting tool when positioning the dusting tool in the predetermined dusting position. The first operating variable may reflect a mechanical load of the drive motor due to the contact with the component to be dusted. The method may further include calculating a corrected dusting position as a function of the predetermined dusting position and the first operating variable of the drive motor, and positioning the dusting tool in the corrected dusting position.

  • Patent number: 8293019
    Abstract: Methods for cleaning a surface of a substrate and for increasing the useable lifetime of a photomask substrate are provided. In one method, a substrate has at least one radiation-produced particle disposed thereon, and a laser that has a wavelength that substantially coincides with a high absorption coefficient of the substrate is directed towards the substrate. A thermal increase is generated in the substrate, and the radiation-produced particle is removed from the substrate by transferring thermal energy from the substrate to the radiation-produced particle until the radiation-produced particle decomposes.

  • Patent number: 8293020
    Abstract: A megasonic cleaning method and a megasonic cleaning apparatus are provided. Microcavitation bubbles may be formed by applying an electromotive force to a cleaning solution using a megasonic energy in a separate room from an object to be cleaned. The microcavitation bubbles having a stable oscillation among the formed microcavitation bubbles may be moved to the object to be cleaned. A surface of the object to be cleaned may be cleaned using the microcavitation bubbles having the stable oscillation. Particles attached onto the surface of the object to be cleaned may be effectively removed while preventing pattern damage.

  • Patent number: 8287655
    Abstract: A method of cleaning dirt and debris from surfaces using a cleaning device, such as a vacuum cleaner. The cleaning device has a handle unit which is attached to the body of the cleaning device adjacent a filter compartment. The handle unit has a handle portion that is spaced from the filter compartment to allow a user to place his or her hand through the space and grasp the handle portion and thereby carry the cleaning device using only the handle unit. The handle unit can also be detached from the body of the cleaning device, and then later re-attached, via lockable mating connecting elements.
