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.

An automatic agricultural machine according to the present invention includes: a fixed base disposed on farmland; a first-direction movement guide part installed on the fixed base so as to be spaced apart from the farmland; a first-direction movement trolley configured to travel on the first-direction movement guide part; and an automatic spraying device configured to travel on a second-direction movement guide part connected to the first-direction movement trolley, wherein traveling control of the first-direction movement trolley and winding control of the second-direction movement guide part are performed on the basis of at least any one of the trigonometric function principle and the Pythagorean theorem.

A method for cleaning at least one workpiece and a cleaning device are described. The method includes: cleaning at least one workpiece held by a workpiece carrier in a treatment container, by at least one nozzle which discharges a cleaning jet directed onto the workpiece. The cleaning includes: specifying a rotational speed of the workpiece carrier and a circulation speed of the at least one nozzle on a circulation track about the workpiece carrier; rotating the workpiece carrier at the specified rotational speed; moving the at least one nozzle at the specified circulation speed about the workpiece carrier; and pivoting the at least one nozzle about a pivoting axis extending parallel to an axis of rotation of the workpiece carrier such that a specified point on a surface of the workpiece is impacted repeatedly by the cleaning jet at a respectively different angle, within a specified timeframe.

To reduce an influence of a flow of ambient atmosphere and the like on flying of a droplet ejected from a nozzle of an inkjet head. To exhaust vapor of a solvent contained in a coated film while reducing an influence on flying of the droplet. An exhaust device for inkjet coating includes: a cover that covers at least a target range on an object to be coated, the target range being a range in which a droplet lands that is ejected from an ejection nozzle of an inkjet head to a surface of the object to be coated; a closing member that closes a gap between the cover and the object to be coated around the target range; an external communication portion through which a compartment surrounded by the cover, the object to be coated, and the closing member communicates with an outside; and an exhaust mechanism configured to exhaust air from the compartment.

A washing machine, which is adapted for cages and accessories used in the field of research on laboratory animals, and which has a wash chamber and an assembly for introducing washing liquid and rinsing liquid into the wash chamber, includes: two loading levels in the wash chamber, each loading level having two shelves arranged in symmetrical positions relative to the median longitudinal axis of the wash chamber; supports for the shelves, the supports being located in symmetrical positions on both sidewalls of the wash chamber and allowing the shelves to be arranged at different tilting angles; three washing and rinsing assemblies oscillating and rotating about a respective longitudinal axis in the wash chamber, the three assemblies being fed by the assembly for introducing washing liquid and rinsing liquid, and being interposed between the loading levels and lying in a symmetrical vertical plane in the wash chamber; an assembly for causing the oscillation and rotation of the three washing and rinsing assemblies.

A carriage assembly for a spray coating apparatus and a spray coating apparatus including the carriage assembly. The carriage assembly includes a carriage operatively connected to a track that is non-linear, which in some embodiments allows a coating to be applied at at least two different thicknesses.

A smart nozzle assembly includes a nozzle, a nozzle control mechanism, and camera rigidly attached to the nozzle for use with a mobile robot in an autonomous spray painting system. The nozzle control mechanism is configured to control flowrate, control the shape of the spray pattern, mix two or more colors, and clean dried paint at the nozzle tip. The nozzle assembly further includes a process for running software to manage or initiate the nozzle control mechanism's functionality and to provide the nozzle calibration. The calibration method for the nozzle uses a novel algorithm that measures the spray pattern, the distribution of paint within the spray pattern, and the relative position of the nozzle and camera. The distribution of paint within the spray pattern is measured in terms of physical quantity of delivered paint per unit area.

An apparatus and method for cleaning the interior of an above ground storage tank includes a nozzle assembly mounted to a cover on the storage tank sidewall having a horizontally extending wash pipe fixedly and a suction pipe for recirculation of spent fluids. The wash pipe has an interior segment which can be extended to a tank floor and is configured with a bend to extend along the tank sides all to which is attached a submersible swivel joint fitted with a choked nozzle. A control assembly is provided to direct from the nozzle from the exterior of the storage tank. The nozzle vibrates in response to flow of wash fluid from the wash pipe.

A tool holder and spray nozzle on an extension pole. In a preferred embodiment the device uses an extension pole with a brush retention mechanism on the end of the pole. The extension pole has a spray brush on the end of the pole configured to spray stain or paint in front of the brush as the brush travels along a deck or other substrate.

A substrate processing apparatus according to the present disclosure includes a holding unit, a nozzle, a driving unit, and a controller. The holding unit holds a substrate. The nozzle supplies a processing liquid to the substrate held on the holding unit. The driving unit moves the nozzle. The controller controls the driving unit, so as to move the nozzle while supplying the processing liquid to the substrate from the nozzle. Further, the controller controls the driving unit based on recipe information including step information including positions of first and second points above the substrate, total time for moving the nozzle between the first and second points, and a moving speed of the nozzle, so as to cause reciprocation of the nozzle.
