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 Digital decorating machine for ceramic products, including a conveyor, suitable to transport the products to be decorated (P) along a feed direction (A), and a plurality of decoration modules, positioned over the conveyor and adjacent to each other along the feed direction (A). The modules include respective printing heads provided with nozzles for ejecting a fluid to be delivered on the surface of the products to be decorated (P); the conveyor includes a movable member for supporting the products to be decorated (P), suitable for translating them along the feed direction (A). The conveyor includes at least a supporting surface, located along a respective flank of the movable member, including in turn a plurality of predetermined positioning zones for the removable engagement of respective coupling portions of the decoration modules.

The droplet discharge device includes a liquid chamber which is in communication with a nozzle and to which a liquid material is supplied, a plunger having a tip portion that is thinner than the liquid chamber and that is moved back and forth in the liquid chamber, a piezoelectric actuator serving as a drive source that operates the plunger to be moved back and forth, a lever mechanism that increases a displacement of the piezoelectric actuator, a base having a mounting surface to which the piezoelectric actuator is mounted, and a discharge control device. The lever mechanism includes an arm that is operated to perform a swinging motion by the piezoelectric actuator, and a leaf spring including ends that are linked to a lower portion of the arm and to the base, and a plunger-linked portion in a central region thereof.

The present invention provides a discharge device (1) including a liquid chamber (13) that is communicated with a discharge port (11) and is supplied with a liquid material, a plunger (33) that is coupled to a piston (30), and that advances and retreats within the liquid chamber (13) in a state not in contact with a lateral surface of the liquid chamber (13), a resilient member (40) that applies a biasing force to the plunger (33), a main body (2) including a piston chamber (20) in which the piston (30) is disposed, solenoid valves (61, 62, 63 and 64) that supply a pressurized gas, supplied from a pressurized gas source, to the piston chamber (20), or that exhaust the pressurized gas from the piston chamber (20), and a controller (90) that controls operations of the solenoid valves (61, 62, 63 and 64), wherein the solenoid valves (61, 62, 63 and 64) are connected to the piston chamber (20) in parallel. With those features, the size of the discharge device can be reduced, and the plunger can be operated at a high speed.

Systems useful for reinforcing a support mat over at least one seam formed between upper and lower panels of the mat include at least one extruder configured to apply weld-forming material over the seam(s) to form at least one weld atop the seam(s) and at least one electronic controller associated with the extruder.

A method of reinforcing a support mat includes at least one extruder applying at least a first stream of weld-forming material over at least one seam formed between upper and lower, interconnected, at least partially overlapping, panels on the top of the mat and at least one automated extruder applying at least a second stream of weld-forming material over at least one seam formed between the panels on the bottom of the mat.

A jetting device and/or fluid module includes a nozzle with a fluid outlet, a body including a fluid chamber and a fluid inlet in fluid communication with the fluid chamber, and a valve seat disposed in the fluid chamber, where the valve seat includes an opening in fluid communication with the fluid outlet. The jetting device also includes a movable element having a top portion and a bottom portion, where the top portion is disposed external to the fluid chamber and arranged to be contacted by a reciprocating drive pin, and where the bottom portion is disposed within the fluid chamber. Finally, the jetting device also includes a sealing member contacting the movable element between the top portion and the bottom portion, where the sealing member also contacts the body, and defines a portion of a boundary of the fluid chamber to seal the fluid chamber.

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.
