  • Patent number: 9533319
    Abstract: An aerosol generator includes a first body having a first end including an exit opening, and an oppositely positioned second end. An open channel second body is substantially positioned inside the first body and extends from the first end to the second end of the first body. An exit opening of the second body is positioned adjacent to the exit opening of the first end of the first body. An insert, which holds material to be aerosolized, is at least partially positioned inside the second body. An inlet opening receives compressed air into the first body. The compressed air flows towards the exit opening of the first end of the first body. The air flow creates a region of low pressure at the exit opening of the second body. The region of low pressure pulls the material out from the second body and aerosolizes the material. The aerosol generator is particularly effective in generating aerosols from small amounts of solid and liquid materials with minimal losses of material.

    Abstract: A device for dispensing individual components of a two-component adhesive includes first and second manifold members, each having a distribution chamber therein. A set of conveying tubes is supported within the dispensing device and collectively present a predetermined total cross-sectional flow area to the first distribution chamber. The second manifold member has an array of passages therethrough. Each tube extends substantially concentrically through a respective passage to define annular flow spaces that collectively present a predetermined total cross-sectional flow area to the second distribution chamber member. First and second components emanating from the tubes and the flow spaces are able to intermix with and diffuse into each other on the discharge area of the second manifold member. The cross-sectional flow areas presented to the first and second distribution chambers are equal.

A set of conveying tubes is supported within the dispensing device and collectively present a predetermined total cross-sectional flow area to the first distribution chamber. An array of openings and an array of passages extend through the second member. The openings receive the discharge ends of the conveying tubes. The passages are disposed in fluid communication with the second distribution chamber. The passages collectively present a predetermined total cross-sectional flow area to the second distribution chamber member. The openings and the passages are laterally spaced with respect to each other such that the discharge ends of the tubes are interspersed among the passages. The cross-sectional flow areas presented to the first and second distribution chambers are different.

  • Publication number: 20140123900
    Abstract: A gas shower device having gas curtain comprises a first gas shower unit for injecting a reaction gas, thereby forming a reaction gas region, and a second gas shower unit. The second gas shower unit arranged around a periphery of the first gas shower unit comprises a buffer gas chamber for providing a buffer gas, and a curtain distribution plate. The curtain distribution plate further comprises a plurality through holes for injecting the buffer gas, thereby forming a gas curtain around a periphery of the reaction gas region. In another embodiment, an apparatus for depositing film is provided by utilizing the gas shower device having gas curtain, wherein the gas curtain prevents the reaction gas in the reaction gas region from being affected directly by a vacuum pressure so that a residence time of reaction gas can be extended thereby increasing the utilization of reaction gas and film-forming efficiency.
