An aircraft controlled by compressed air according to an embodiment of the present invention comprises: a fuselage (10) having main wings (20) on both sides thereof; a first nozzle (12) mounted to the roof of the fuselage (10); second nozzles (22) mounted on the top surfaces of the main wings (20); a first tank (31) disposed in the fuselage (10) or the main wings (20) and storing compressed air; and a main control valve (40) for controlling the compressed air so that the compressed air is provided to the first nozzle (12) or the second nozzles (22).

A cleaning device for selectively applying a first medium to a surface includes a high pressure reservoir configured to store the first medium held under a storage pressure, a pulse nozzle configured to apply the first medium under the storage pressure in a pulsed manner to the surface, and a switching valve that includes a nozzle port and a high pressure reservoir port for selectively establishing a first connection between the high pressure reservoir and the pulse nozzle, and a feed port for establishing a second connection between the high pressure reservoir and a first medium source. The high pressure reservoir and the switching valve are structurally integrated in a reservoir valve module. The switching valve comprises a solenoid valve to switch between the first and the second connection when the high pressure reservoir port is under the storage pressure.

A device for spraying substrates comprises a longitudinal extending fluid dispensing head coupled to a supply of fluid and including a perpendicularly extending flange, a spacer having first and second ends, the first end of the spacer coupled to the extending flange of the dispensing head, a nozzle adapted to eject fluid coupled to the second end of the spacer, and a locking nut enclosing the spacer and securely the dispensing head, spacer and nozzle.

A system for mixing and mixing processes and structures are disclosed. In addition a nozzle used for mixing is disclosed.

Apparatus and a method for removing particulate matter from an enclosure having an internal space and an opening into the internal space. The apparatus includes: a cover positionable over the opening; an inlet conduit that extends through the cover and is adapted to direct gas from a gas source to a gas outlet within the internal space so that particulate matter within the internal space is dislodged. Gas and entrained particulate matter is drawn from the internal space firstly through an outlet conduit and the particular matter is separated. Concentration of particulate matter in gas leaving the enclosed space is sensed and its value displayed to an operator so that operation can continue until a satisfactory value of the concentration is achieved. The gas outlet may be comprised in an elongate lance that is passed through the cover and can be manipulated by a user. The lance may display data.

A substrate processing apparatus includes: a rotation support table capable of supporting and rotating a substrate; a chemical liquid nozzle that is arranged above an outer edge portion of the substrate that is supported by the rotation support table, and through which a chemical liquid is applied to the outer edge portion; and a solidified film forming unit that is arranged at least either on an upper side or on a lower side of the outer edge portion of the substrate that is supported by the rotation support table, and on a downstream side, in a direction of rotation of the substrate, of a position where the chemical liquid nozzle is arranged, and solidifies the chemical liquid applied to the outer edge portion, to form a solidified film that forms a part of an annular film.

The present invention relates to a plumbing fixture and a shower bathing system capable of dispensing water spray and drying air. More specifically, the plumbing fixture has a plurality of nozzles or openings for dispensing water and one or more central air vents for blowing out air. The air is produced by a blower and is carried to the air vents through an air carrying pipe. The showerhead has an integrated timer for calculating the time of water dispensing or cessation and is configured to automatically activate the blowing of air when the elapsed time matches a preconfigured value. The showerhead has proximity sensors for automatically deactivating the dispensing of water and stopping blowing out hot air.

Presented herein is a corrosion inhibitor dispensing system that provides for the in-situ application of a corrosion inhibitor in order to protect internal elements of an apparatus from corrosion. In one example, an apparatus is provided that may include a housing to contain one or more electronic components. The housing includes air inflow ports configured to limit internal air from exiting the housing during a corrosion inhibitor dispensing processes, air outflow ports configured to limit external air from entering the housing during the dispensing process, and one or more fans to direct airflow for the housing. The apparatus further includes a corrosion inhibitor dispensing system that includes a dispensing container to hold a corrosion inhibitor in a non-vaporized state and includes one or more ports for dispensing the corrosion inhibitor in a vaporized state during the corrosion inhibitor dispensing processes. A controller is provided to manage the dispensing process.

Embodiments of showerheads for use in a process chamber are provided herein. In some embodiments, a showerhead includes a first spiral channel extending from a central region to a peripheral region of the showerhead; a second spiral channel extending from a central region to a peripheral region of the showerhead, wherein the second spiral channel is interleaved with the first spiral channel and fluidly independent from the first spiral channel; a plurality of first channels extending from the first spiral channel to a plurality of first gas distribution holes on a lower surface of the showerhead, wherein each first channel is a singular channel extending at an angle; and a plurality of second channels extending from the second spiral channel to a plurality of second gas distribution holes on the lower surface of the showerhead, wherein each second channel is a singular channel extending at an angle.

A system for mixing and mixing processes and structures are disclosed. In addition a nozzle used for mixing is disclosed.
