  • Patent number: 9941165
    Abstract: A semiconductor manufacturing method includes forming a first metal film on a semiconductor wafer by plating, ejecting liquid from a washer bar spaced from the wafer while rotating at least one of the washer and the semiconductor, and forming a second metal film on the first metal film. A plurality of nozzles are located on the washer bar and displaced from the position of the washer bar opposed to the center of the wafer, and a greater number of nozzles are adjacent the peripheral area of the semiconductor wafer than the central area of the semiconductor wafer. The nozzles in the peripheral area of the wafer eject the washing liquid in a direction inclined from the direction of the washer bar, and a nozzle arranged on the central area of the one main surface of the semiconductor wafer ejects the washing liquid towards the center position of the semiconductor wafer.

The valve-closure member cooperates with a valve-seat surface to form a sealing seat. A multitude of spray-discharge orifices generates a spray cloud, each spray-discharge orifice generating a fuel jet, and the multitude of fuel jets generating the spray cloud in the combustion chamber. A first opening angle of the spray cloud in a first plane is greater than a second opening angle in a second plane extending perpendicular to the first plane.

  • Patent number: 8196848
    Abstract: A gasifier injection module includes a two-stage slurry splitter and an injector face plate with a coolant system incorporated therein. The two-stage slurry splitter includes a main cavity into which a main slurry flow is provided. The main cavity includes a plurality of first stage flow dividers that divide the main slurry flow into a plurality of secondary slurry flows that flow into a plurality of secondary cavities that extend from the main cavity. Each secondary cavity includes a plurality of second stage flow dividers that divide each secondary slurry flow into a plurality of tertiary slurry flows that flow into a plurality of slurry injection tubes extending from the secondary cavities. The tertiary flows are injected as high pressure slurry streams into the gasification chamber via the slurry injection tubes. A reactant is impinged at high pressure, as an annular shaped spray, on each high pressure slurry stream via a plurality of annular impinging orifices incorporated into the injector face plate.

  • Publication number: 20120080543
    Abstract: A device for humidifying a bulk material, particularly for humidifying power plant filter ash, comprises a downpipe. At the upper end of the downpipe, there is formed an inlet, through which the bulk material enters the downpipe, and at the lower end of which there is formed an outlet, through which the bulk material leaves in a humidified state. A plurality of water nozzles are arranged on a first plane in the downpipe and a plurality of water nozzles are arranged on a second plane in the downpipe. The water nozzles of the first plane are arranged offset at an angle to the water nozzles of the second plane. With the device and a corresponding method, the bulk material can be humidified effectively and deposits of the bulk material can be removed from the downpipe.

  • Patent number: 8118109
    Abstract: A system by which a building structure is protected from wildfires, adjacent structure fires, and similar disasters while also affording a method to clean the roof using a plurality of specially-formed shingles, end caps, and ridge units designed to deliver a dispersing water spray, is herein disclosed. The shingles and ridge units would be provided in sectional pieces that interconnect theretogether to extend across a roof area. The end cap units provide plumbing connections thereto connected shingle units and a central water supply line within the structure. The system covers the roof and end wall areas of the building structure with water, thereby preventing ignition from an external source to take place. The system can also be used to clean the roof of dirt and debris if desired, and may additionally protection from chemical, biological, and/or radiological (CBR) attacks by rinsing off contaminates.
