The present invention relates to the field of semiconductor manufacturing technology, more particularly to a swing spray device of a cleaning apparatus and a cleaning method. The swing spray device comprises a spray arm, a spray head and a driving unit. The spray head is connected with the spray arm, and is controlled to swim by the driving unit. The spray head is hinged with the spray arm to form a first hinge joint. The driving unit is an air cylinder; the piston rod of the air cylinder is connected with the spray head. The piston rod is hinged with the spray head to form a second hinge joint. Therefore, the better cleaning effects can be achieved both in the center and the edge of the wafer.

A spray booth for spraying pieces to be painted with a painting product includes a system that conveys the pieces to be painted inside the booth, a supplying circuit that supplies a painting product or solvent to painting tools, a plenum, a mobile wall providing access to the inside of the spray booth, optionally a reading system for the pieces to be painted, optionally a filtering system, a plurality of spraying tools that include one or more a spray guns each placed on an independent arm moving on a plane and optionally in a vertical direction, one or more cleaning stations, placed in correspondence of the mobile wall and provided with a drawer that is mobile between rest and a cleaning positions and that includes a painting product or solvent draining tube having a mouth, a slot for supplying compressed air, and a brush for brushing the spray guns.

An aircraft windshield wiper system includes a wiper arm, a wiper blade coupled to a first end of the wiper arm, and an output shaft coupled to a second end of the wiper arm. The wiper blade includes a fluid dispensing system including nozzles, a fluid control unit, fluid lines, fluid source, and a user interface. The wiper blade with the fluid dispensing system is configured to dispense a variety of fluids directly from the wiper blade onto the windshield of an aircraft.

A sensor assembly includes a first sensor window defining a first plane, a second sensor window fixed relative to the first sensor window and defining a second plane different than the first plane, and a nozzle positioned to deliver fluid to the first and second sensor windows. The nozzle is translatable along a first axis, rotatable about the first axis, and rotatable about a second axis transverse to the first axis.

Provided is a sanitary cleansing device configured to less provide a feeling of insecurity to a user when a cleansing mode for moving a water splash point in at least two directions is used. The present invention provides a sanitary cleansing device (1) including a nozzle assembly (6) provided with a spray port, a nozzle drive device (12), an operation device (10) operated by a user to switch a cleansing mode, and a spray control device (20) configured to switchably execute, a fixed spot cleansing mode in which the spray port is stopped at a predetermined reference private area position and a wide movement cleansing mode for moving a water splash point in at least two directions. When the wide movement cleansing mode begins, the spray port is positioned at the reference private area position, and then, starts movement of the water splash point.

Aspects of the present invention provide a method and an apparatus for delivering a solution to a region of a human body, and washing, cleaning, and drying the region. The apparatus include a toilet seat assembly, and a spraying nozzle assembly. The spraying nozzle assembly includes one or more spray nozzle units having one ore more spray nozzle bodies that are retractable and adapted to deliver the solution, a first driving motor being connected to the one or more spray nozzle units and adapted for moving the one ore more spray nozzle bodies in retracting-and-extending motion, and a second driving motor being connected to the one or more spray nozzle unit and adapted for moving the one or more spray nozzle units in three-dimensional circular rotational motion. The one or more spray nozzle units may further include one or more nozzle jet head openings.

Aspects of the present invention provide a method for using an apparatus to deliver medicine and to wash, clean, and dry a region of a human body. The apparatus include a toilet seat assembly and a medicine delivery assembly. In addition, the apparatus may include a drying nozzle assembly and/or a spraying nozzle assembly. The medicine delivery assembly may include one or more medicine storage cartridges and/or one or more medicine base units, each medicine base unit includes at least a cartridge unit and at least a cartridges slot, wherein the cartridge slot is adapted to match with a medicine storage cartridge. The medicine delivery assembly may include a medicine delivery nozzle, which can be coupled to a spraying nozzle assembly, or may be operated by itself with a medicine delivery nozzle. Finally, the medicine delivery assembly can be controlled by one or more control units.

An apparatus (100) for applying product to the skin of a person in a booth (10), comprising: an applicator (57) configured to apply the product to the person; a first guide (40) configured to guide movement of an applicator in a first dimension, in order to enable the applicator to apply the product to the person at a plurality of different heights; and a second guide (20) configured to guide movement of the applicator in a second dimension, in order to enable the applicator to apply the product across the width of the person. The apparatus may comprise control circuitry for controlling the applicator in dependence upon the weight of the person.
