The disclosure relates to an applicator, in particular a printhead, for applying a coating agent, in particular a paint, to a component, in particular a motor vehicle body component or an add-on part for a motor vehicle body component, having at least one nozzle row with a plurality of nozzles for dispensing the coating agent in the form of a coating agent jet, the nozzles are arranged one behind the other in a nozzle plane along the nozzle row at a specific nozzle spacing, and having a plurality of actuators for controlling the release of coating agent through the individual nozzles, the actuators each having an outer dimension along the nozzle row. The disclosure provides that the nozzle distance between the adjacent nozzles of the nozzle row is smaller than the outer dimension of the individual actuators along the nozzle row.

Embodiments of the disclosed subject matter provide a device including a carrier plate, and a die including a mating surface with a patterned thin film of metal or metal oxide surface bonded to the carrier plate using a solder preform with voids that overlay the patterned thin film on the die, where the oxide surface is disposed opposite a moat in a mating surface of the carrier plate, and where the voided regions remain free of solder when the solder is reflowed.

The present application discloses biopolymer-based ink formulations that are useful for inkjet printing and other applications. Related methods are also disclosed.

A liquid discharge apparatus includes a plate-like actuator including a plurality of individual electrodes aligning in a first direction, a channel member being joined to one surface of the actuator to include a plurality of pressure chambers aligning along the first direction, and a heater being arranged directly or indirectly on the other surface of the actuator and having a convex portion in direct or indirect contact with the plate-like actuator. The convex portion is arranged between the plurality of individual electrodes and an outer edge of the actuator.

A printing apparatus includes a feeder that feeds a medium in a feeding direction, a head including a row of nozzles arranged side by side in the feeding direction and movable in a scanning direction, an irradiator that radiates light onto a region longer in the feeding direction than the nozzle row and that is movable in the scanning direction together with the head, and a controller that alternatingly causes the head to move in the scanning direction and concurrently the nozzles to discharge ink while causing the irradiator to radiate the light, and the feeder to feed the medium in the feeding direction. The controller is capable of dividing the nozzle row into an upstream-side nozzle row and a downstream-side nozzle row located on a downstream side in the feeding direction from the upstream-side nozzle row, and individually controlling discharge of ink from the nozzles of each of the upstream-side nozzle row and the downstream-side nozzle row. The controller is capable of dividing the irradiator into an upstream-side irradiator, an intermediate irradiator adjacent to the upstream-side irradiator on a downstream side in the feeding direction, and a printless region irradiator adjacent to the intermediate irradiator on a downstream side in the feeding direction, and individually controlling lighting and extinguishing of each of the irradiators defined by the division.

A valve jet printer includes a solenoid coil and a plunger rod having a magnetically susceptible shank. A first end of the shank and at least a portion of the shank are received within a bore of the solenoid coil. The printer also includes a nozzle including an orifice extending therethrough and a spring biasing a second end of the shank toward the nozzle. The second end of the plunger rod includes a tip formed of perfluoroelastomer (FFKM). The second end of the shank includes a cup-shaped cavity having a convex bottom and a circular side. The tip includes a concave base and an annular flange. In an assembled state, the concave base of the tip contacts the convex bottom of the cup-shaped cavity, and the end of the circular side opposite the convex bottom is rolled over the annular flange thereby securing the tip in the cup-shaped cavity.
