Embodiments are directed to nozzles for three-dimensional printing and related assemblies and methods. An example method includes, on a first side of a material, forming a hole into the material to define an at least partially conical inner conduit extending at least partially through the material, and, on a second side of the material, forming a through-hole into the material to define an exit orifice of the nozzle, the exit orifice connecting with the at least partially conical inner conduit to define a fluid pathway through the nozzle.

A dispensing head for a supply tube that enables material to be evenly applied adjacent to the peripheral edge of a thin structure, such as a vehicle door. The dispensing head has a first end with a first opening and a second end with a discharge opening. A guide extends from the second end. The guide includes a descending element and a lateral foot element, wherein the bottom surface of the second end, the descending element, and the lateral foot element define three sides of an open gap space. The dispensing head is attached to a supply tube. The thin structure is positioned within the guide. The hook shaped guide positions the discharge opening a set distance from the application surface on the thin structure. The guide is moved along the peripheral edge where the material can be dispensed evenly at a set distance from the peripheral edge.

A shower device for creating at least one water jet pattern with a structural assembly, with a nozzle assembly and with a lighting assembly. It is proposed that the structural assembly provides an exit opening for the emergence of the water discharged by the nozzle assembly and comprises an outer edge region running about the edge of the exit opening, that the exit opening during shower operation is only partially occupied with emerging water at any given time, that the nozzle assembly is arranged distributed along at least a portion of the edge of the exit opening at the edge region and that the path of the water discharged by the nozzle assembly during the shower operation runs each time from the edge region in the direction of the exit opening and then through the exit opening.

An applicator for a syringe is provided that includes a hub configured to be disposed at least partially within a nozzle of the syringe and defining a fluid passage therethrough, with one or barbs on the hub that frictionally and sealingly engage an interior of the nozzle in a manner minimizing void space associated with waste of deliverable material, and an applicator tip extending distally from the hub. The barb(s) may have varying diameters in order to enable the applicator to be engaged and utilized with syringes having different diameter nozzles. Further the fluid passage through the hub and applicator tip is dimensioned to minimize the volume of material that is retained within the applicator after use, thereby increasing the volume of material that can dispensed from the syringe for use in a procedure or procedures and minimize waste.

A substrate processing apparatus includes a holder configured to hold a substrate; a driving unit configured to rotate the holder; an inner cup body provided in the holder to surround the substrate held by the holder; a mist guard, surrounding the holder and the inner cup body, configured to be moved up and down; a cleaning liquid supply configured to supply a cleaning liquid; and a controller. The controller is configured to perform: supplying a processing liquid to the substrate from a processing liquid supply, in a state that the substrate is held by the holder and the mist guard is raised; and dispersing, after the supplying of the processing liquid, the cleaning liquid supplied from the cleaning liquid supply to an entire inner peripheral surface of the mist guard, in a state that the substrate is carried out from the holder and the mist guard is raised.
