A coating device comprises at least one application apparatus to discharge a coating agent from at least one coating agent nozzle. The application apparatus is configured to apply an oscillation to at least one of the coating agent and at least one coating agent jet such that at least one of the coating agent and the at least one coating agent jet break up into droplets.

A coating device provided for connection to a discharge pipe of a coating container, includes a guide base and a cover. The cover is pivoted to the connecting end of the guide base, so that the cover can cover the guide section of the guide base to close the coating device, and can also be pivoted with respect to the guide base to open the coating device, which makes it convenient for the user to take out the residue of coating material from the guide space, so that the coating device can be used repeatedly. Furthermore, the coating material is guided by the guide ribs and the cover ribs to flow evenly to each of the discharge holes, which ensures even distribution of the coating material from the coating device.

A perforated plate is provided for an application device for the application of a coating agent, in particular a paint, a sealant, a glue or a separating agent, to a component, in particular to a motor vehicle body component. The perforated plate contains at least one through-hole for passing the coating agent through and a hole exit opening on the side of the perforated plate that is located downstream with a wetting surface that can be wetted during operation by the coating agent. The through-hole, to reduce the wetting tendency, transitions into a protruding pipe stub or has a structure that reduces the wetting tendency and/or improves the flushability, e.g., a microstructuring or a nanostructuring.

A method for depositing thin films using a nominally curved substrate. Drops of a pre-cursor liquid organic material are dispensed at a plurality of locations on a nominally curved substrate by one or more inkjets. A superstrate is brought down on the dispensed drops to close the gap between the superstrate and the substrate thereby allowing the drops to form a contiguous film captured between the substrate and the superstrate. A non-equilibrium transient state of the superstrate, the contiguous film and the substrate is enabled to occur after a duration of time. The contiguous film is then cured to solidify it into a solid. The solid is separated from the superstrate thereby leaving a polymer film on the substrate. In this manner, such a technique for film deposition has the film thickness range, resolution and variation required to be applicable for a broad spectrum of applications.

A coating device comprises at least one application apparatus to discharge a coating agent from at least one coating agent nozzle. The application apparatus is configured to apply an oscillation to at least one of the coating agent and at least one coating agent jet such that at least one of the coating agent and the at least one coating agent jet break up into droplets.

An application device and an application method capable of increasing the speed of a line-drawing application are provided. The application device includes a discharge device, a worktable, a drive device, and a control unit. A discharge member gives an inertial force to a liquid material inside a liquid chamber, thereby discharging the liquid material from a plurality of discharge ports at the same time and forming a plurality of droplets on an application object. The plurality of discharge ports are arranged in a nozzle along a straight nozzle arrangement line, and the nozzle arrangement line is aligned with a drawing direction in which a drawing line is to be drawn. The application device performs the line-drawing application by discharging the liquid material such that a plurality of liquid masses discharged from the plurality of discharge ports do not contact with each other prior to landing on the application object, and that the liquid material having landed along the nozzle arrangement line join together on the application object.

Systems for the manufacturing of waveguide cells in accordance with various embodiments can be configured and implemented in many different ways. In many embodiments, various deposition mechanisms are used to deposit layer(s) of optical recording material onto a transparent substrate. A second transparent substrate can be provided, and the three layers can be laminated to form a waveguide cell. Suitable optical recording material can vary widely depending on the given application. In some embodiments, the optical recording material deposited has a similar composition throughout the layer. In a number of embodiments, the optical recording material spatially varies in composition, allowing for the formation of optical elements with varying characteristics. Regardless of the composition of the optical recording material, any method of placing or depositing the optical recording material onto a substrate can be utilized.

A coating device coats a to-be-coated object including a recessed portion extending in a first direction. The coating device includes a head, an arm, and a controller. The head includes a nozzle surface. The arm holds the head. The controller controls movement of the head via the arm. The controller moves the head in the first direction while causing the nozzle surface and the recessed portion to face each other in a posture in which a length of a first component along the first direction of the head is larger than a length of a second component of the head intersecting the first component.

Problem: To provide a technology for forming a planar liquid film having less surface unevenness than ever before using a jet-type discharge device. Solution: Provided is a planar liquid film forming method of forming a planar liquid film on an application target using a jet-type discharge device having a plurality of discharge ports, and an apparatus for implementing the method. In the method, the plurality of discharge ports are arranged on a straight nozzle arrangement line 140, and are arranged with such a distance from one another that globs of a liquid material having landed on the application target can join together to form a linear liquid film. The method includes: a unitary linear liquid film forming step of forming a unitary linear liquid film 404 by discharging the liquid material such that a plurality of liquid globs simultaneously discharged from the plurality of discharge ports have no contact with one another before landing on the application target, and by letting globs of the liquid material having landed join together on the application target; and a specific planar liquid film forming step of forming a specific planar liquid film 405 from a plurality of unitary linear liquid films 404 by successively executing the unitary linear liquid film forming steps while moving the jet-type discharge device and the application target relative to each other in a direction perpendicular to the nozzle arrangement line 140 so that the plurality of unitary linear liquid films 404 join together.

The present injection apparatus is designed for replenishing embedded foundation preservation wraps with preservative whilst avoiding spillage. The injection apparatus comprises an injection bayonet having a lumen fluidly interfacing a plurality of preservative outlet nozzles along the injection bayonet and a preservative inlet fluidly interfacing the lumen. A portable preservative containing tank may be attached to the inlet via a flexible hose. The apparatus further comprises a syringe operating between the preservative inlet and the lumen. When replenishing the preservation wrap, the injection bayonet is inserted between the preservation wrap and the foundation so that preservative is configured to be supplied via the preservative inlet to flow out from the nozzles via the lumen to replenish the preservation wrap with the preservative. After replenishment, the lumen is purged of residual preservative using the syringe.
