    Abstract: The present invention discloses a cleaning process, utilizing a gas flow to an interior of a hollow object in a fluid ambient. After capping the object to seal off the interior volume, gas is introduced to the object interior. The pressure is built up within the object interior, loosening the seal. The gas pressure is released, and the seal returns. The vibration caused by the cycling of gas pressure can be used to perform cleaning of particles adhering to the object. The cleaning process can be used in a combinatorial processing system, enabling in-situ cleaning of process reactor assemblies.

The disc-type yarn tensioner comprises an axle on which two brake plates are rotatably mounted by means of one rotary bearing each. It further comprises a pressure mechanism for applying axial pressure forces to the brake plates, which pressure forces press the brake plates against each other. The pneumatic cleaning device comprises at least one nozzle whose flow axis is directed from the outside substantially towards one of the rotary bearings. The compressed air flow exiting from the nozzle cleans the disc-type yarn tensioner. It is thus ensured that the rotary bearings of the brake plates accumulate less dirt and the rotary movement of the brake plates is braked with the intended braking force.

  • Patent number: 8758523
    Abstract: A method of cleaning a photolithographic mask or semiconductor wafer involves mixing a gas and water in a jetspray nozzle and discharging the gas and water jetspray stream from a nozzle onto the photolithographic mask or wafer. The water jetspray stream is made up of a cluster of micro water droplets entrained in the gas having a predetermined size sufficient to dislodge contaminant particles adhered to the surface of the mask. The step of mixing the gas and water includes radially injecting the gas from a first plurality of circumferentially spaced apart gas nozzles into a stream of the water and radially injecting the gas from a second plurality of circumferentially spaced apart gas nozzles into the stream of the water, wherein the second plurality of gas nozzles are spaced above or below the first plurality of gas nozzles and radially offset from the first plurality of gas nozzles.

  • Publication number: 20140166048
    Abstract: The invention pertains to a method for removing ice layers and/or snow layers and/or dirt layers from the rotor blades of axial fans in cooling installations for refrigerating and/or freezing products. At least one cleaning substance jet is directed toward the rotor blades of an axial fan within certain time intervals in such a way that ice layers and/or snow layers and/or dirt layers are at least separated from the surfaces of the rotor blades and transported away, wherein the rotor blades rotate with nominal speed while cleaning jets act upon their surfaces.

  • Publication number: 20140138353
    Abstract: A process is described to perform lift-off of a metal layer. A spray is applied to a patterned surface coated with the metal layer. An incidence angle and pressure of the spray are sufficient to separate the metal layer from a substance coated with the metal without separating the substance from an underlying substrate.

  • Patent number: 8728247
    Abstract: There is provided a substrate processing method capable of preventing pattern collapse when a rinse solution is removed from a substrate on which a microscopic resist pattern is formed and also capable of reducing cost for processing the substrate by decreasing an amount of usage of a hydrophobicizing agent. The substrate processing method includes a rinse solution supply process (step S12) for supplying the rinse solution onto the substrate on which the resist pattern is formed; and a rinse solution removing process (steps S14 to S16) for removing the rinse solution from the substrate in an atmosphere including vapor of a first processing solution that hydrophobicizes the resist pattern.

  • Publication number: 20140109940
    Abstract: The present invention generally provides a processing chamber having shadow frame supports that direct cleaning gas flow to the corners of the chamber. The shadow frame supports are disposed along part of the chamber walls, thus leaving the corners unoccupied. During cleaning, the shadow frame is disposed in a way that it rests on both the substrate support and the shadow frame supports. Therefore, the cleaning gas flowing along the chamber walls is blocked by the shadow frame supports and the cleaning gas is forced to the corners since the shadow frame supports do not extend to the corners.

  • Patent number: 8685175
    Abstract: An apparatus and process for isomerizing a hydrocarbon stream rich in a C4 hydrocarbon and/or at least one of a C5 and C6 hydrocarbon which includes a first drier and a second drier; and a reaction zone communicating with at least the first drier. The first drier operates at a first condition to dry the reactant and the second drier operates at a second condition during regeneration. The used regenerant remaining in the second drier after regeneration can (1) pass through a vent-to-flare assembly in a batch-wise manner; (2) pass through a downflow-depressure-to-low-pressure-device assembly in a batch-wise manner; (3) pass through a cross-over piping purge assembly to minimize upsets in the reaction and fractionation zones when the second drier is placed back in operation; or any combination of (1) (2) and/or (3) to minimize upsets in the reaction and fractionation zones when the second drier is placed back in operation.
