An apparatus includes a moving device movable along the surface of an object, and a rotary nozzle device. A rotary nozzle means comprise a plurality of jet nozzles. Two sets of the rotary nozzle means are arranged in parallel in a direction orthogonal to the moving direction of the moving device, are configured such that a left rotary nozzle means and a right rotary nozzle means perform a rotary motion in association with each other by a rotary transmission means. The jet nozzle of the left rotary nozzle means and the jet nozzle of the right rotary nozzle means are arranged so as to be out of phase with each other.

Apparatuses and methods related to improving environmental protection and waste collection from application of deposition material using portable systems that are easier for operators to use on surfaces such as ship hulls are provided. Embodiments include a portable and repositionable deposition material applicator enclosure and application system for applying deposition material on a substrate employing non-adherent deposition material waste removal and selective enclosure coupling and decoupling structures or systems employing magnetic and suction or differential pressure based forces.

A surface adhering mobile coating apparatus includes a surface adhering and traveling device, a spray nozzle, and a spray nozzle X-axis drive device, and a spray nozzle Y-axis drive device. An operation procedure of the coating includes, regarding the timing at which the spray command of the coating material is triggered to the spray nozzle when the spray nozzle is moved from the start point to the end point in the forward or return direction on the X-axis, the timing is the trigger timing at which the spray nozzle leaves the start point in the forward or return direction on the X-axis, therefore, the timing at which the spray is actually started is slightly delayed from the time when the spray nozzle leaves the start point; regarding the timing at which the spray stop command of the coating material is triggered to the spray nozzle when the spray nozzle is moved from the start point to the end point in the forward or return direction on the X-axis, the timing is the trigger timing at which the spray nozzle reaches the part just before the end point in the forward or return direction on the X-axis, therefore, the timing at which the spray is actually stopped is slightly delayed from the time when the spray nozzle reaches the part just before the end point.

A processing apparatus includes a processing chamber cover having a first transverse member extending from between a first side plate and a first delivery port defined in the first side plate outwardly of a first processing chamber. The width of a gap between the first transverse member and a pedestal positioned in the first delivery port when a workpiece is processed in the first processing chamber, i.e., the length of the gap along the direction toward the outside of the processing chamber, is large. When processing water that is scattered passes through the gap, the processing water will likely contact the pedestal or the first transverse member and stay in the gap. As a result, the processing water is effectively prevented from being scattered out of the first processing chamber by a simple structure, compared with water supply means for forming a water film in the gap.

Provided is a liquid ejection device that includes a nozzle that ejects a liquid, a liquid conveying tube that conveys the liquid to the nozzle, an outer tube that is internally provided with the nozzle and the liquid conveying tube, and a first vibration applying unit that applies vibration to the nozzle or the liquid conveying tube. The first vibration applying unit is provided between the nozzle and the outer pipe or between the liquid conveying tube and the outer pipe.

A printing assembly is disclosed for thermal transfer printing onto a surface of a substrate. The assembly comprises at least one first printing system comprising a transfer member having opposite front and rear sides with an imaging surface on the front side, a coating station at which a monolayer of thermoplastic particles is applied to the imaging surface, an imaging station at which energy is applied by a thermal print head, optionally via the rear side of the transfer member, to selected regions of the imaging surface to render particles coating the selected regions tacky, a transfer station at which the imaging surface of the transfer member and the substrate surface are pressed against each other to transfer to the substrate the particles that have been rendered tacky to form an adhesive image; and at least one more printing system downstream from the first system.
