  • Publication number: 20090126632
    Abstract: A tube-array showerhead for CVD or PECVD on large substrates delivers precursors to a process chamber via an array of tubes drilled with precision holes. The tubes rapidly become contaminated with use and must be changed frequently to maintain process quality. An improved manifold for a tube-array showerhead, intended for processes with a low pressure differential between the tubes and process chamber, includes holding-stubs to hold each tube by its ends outside the manifold block. At least one holding-stub for each tube is spring-loaded along the direction of the tube's operating axis. Contaminated tubes can be removed, and clean tubes installed, without disassembling the manifolds or disturbing any high-pressure-differential seals to the ambient atmosphere or precursor supplies. This invention reduces production costs by decreasing chamber down-time and reducing the risk of creating leaks when tubes are changed.

With this arrangement, since the entire aperture area of the water spray holes is reduced, it is possible to achieve water-saving effects. Moreover, since the water spray holes are small and provided by a plurality of numbers, the flow of water sprayed from the respective water spray holes is large to feel some strength hitting the skin and to achieve expansion of shower water so that the sense of using the shower may be satisfied. Moreover, since a plurality of small water spray holes is formed, a larger number of minus ion can be generated.

  • Patent number: 6631859
    Abstract: A showerhead with an internal valve to control the flow of fluid between a full flow and reduced flow condition so as to save energy and thereby conserve the supply of water. The showerhead includes an internal valve that operates easily between an off position and an on position to permit a controlled flow of water from an approximate flow of two and one half gallons per minute to a reduced flow of about one half gallon per minute. The internal valve is formed in a spherical configuration and swivels or rotates between a reduced flow position and a full flow on position; it has formed therein a relatively small by-pass aperture that serves to selectively maintain a predetermined, constant temperature flow of water for a person taking a shower.

  • Patent number: 6622944
    Abstract: A two phase fuel oil atomizer utilizing a secondary media such as high pressure steam or air to assist in the atomization of heavy fuel oil, while reducing NOx and other polluting emissions. The fuel oil atomizer comprises a mixing plate and a sprayer plate which are configured to discharge atomized fuel oil at varying spray angles in order to provide staging of the atomized fuel as it exits the sprayer plate with the surrounding combustion chamber air to provide a fuel/air ratio that is appropriately rich and lean in order to allow lower flame temperatures. NOx generation is accordingly reduced at the lower flame temperatures. With atomized fuel droplet size small enough to enable rapid fuel evaporation and complete combustion, low CO, opacity and particulate generation are achieved with minimum excess oxygen.

  • Patent number: 6588195
    Abstract: This invention relates to a bleed valve of a compressor, in particular a compressor of a bypass aero-engine, with a guiding device provided downstream of a valve body in the bleed duct, said guiding device directing the bleed airflow from a compressor duct to a bypass duct in such a manner that the direction of the flow of the bleed airflow is imparted with a component which is unidirectional with the airflow carried in the bypass duct. The present invention provides a dissipation screen in the bleed duct between the valve body and the guiding device to reduce the energy contained in the bleed airflow, thereby decreasing the loading of the bypass duct. Moreover, the present invention provides for an attenuation chamber downstream of the dissipation screen as viewed in the direction of the bleed airflow.

    Abstract: A shower head having a plurality of nozzles, with the exterior finish of both the shower head housing and the nozzles being consistent. For example, both the shower head and the nozzles may have either a chrome or a brass exterior finish. The nozzles of the shower head of the present invention each include a nozzle insert positioned therein, with the nozzle insert having a flexible nozzle tip protruding from the nozzle. Each nozzle insert includes an passageway in fluid communication with the water inlet of the shower head whereby water introduced into the shower head is ejected from the shower head through the passageway in the nozzle insert. The flexibility of the nozzle tip provides a convenient mechanism for eliminating build-up of, e.g., calcium or other deposits by manually flexing the nozzle tip.

    Abstract: A fire-fighting tool incorporates a twist-lock mechanism whereby various nozzles can be interchanged for particular fire-fighting purposes. Included in such nozzles are a penetrating nozzle having a doubly bevelled front end for easier access through a roof, and various fluid ejection and misting elements that can be configured in terms of fluid aperture angles to produce a mist directed somewhat back towards the user, transverse to the nozzle, or forward from the nozzle. A non-penetrating embodiment of the invention also uses an end ejecting misting region. The foregoing elements can be used in conjunction with various extention wands, which are removably connectable fluid channels bent to various angles, so as to provide easier access to fires that are located within recesses of buildings, motor vehicles, or boats and the like.
