An application needle member capable of eliminating contamination while suppressing reduction in working efficiency is an application needle member capable of applying a liquid material to an object. The application needle member comprises an application needle and an application needle insertion material. The application needle includes a tip facing the object and a bottom opposite to the tip. The application needle insertion material is attached to the bottom of the application needle. The application needle insertion material is configured to be detachably attachable to a fixing member.

A dosage form comprising a tablet core and one or more discontinuous coated regions in various configurations on the surface of the dosage form is disclosed. A method for making the dosage form is also disclosed.

A device for a lacquer transfer includes a frame, transfer roller with a circumferential lateral wall, drive unit for rotating the transfer roller, and slit nozzle with a muzzle end for dispensing lacquer. The slit nozzle includes a first nozzle-part, second nozzle-part and deformation unit. The deformation unit is attached to the first nozzle-part, the lateral wall passing in a rotation direction subsequently the deformation unit and the muzzle end during transfer unit rotation. The lateral wall of the transfer roller is deformed by the deformation unit in the radial direction resulting in a deformation section of the lateral wall in the rotation direction behind the deformation unit, the muzzle end of the slit nozzle arranged for dispensing lacquer into depressions of the lateral wall. The transfer roller can roll with the outside contact surface on a work surface of a work piece for transferring lacquer from the depressions to the work surface of the work piece.

A device for lacquer transfer is disclosed having a frame, a transfer roller with a circumferential lateral wall, and a slit nozzle for dispensing lacquer, wherein an outside contact surface of the lateral wall includes several depressions. The transfer roller is mounted rotatably about an axis of rotation to the frame, wherein the slit nozzle is arranged for dispensing lacquer into respective depressions in the lateral wall while the transfer roller is rotated about the axis of rotation, wherein the transfer roller is configured to roll with the outside contact surface on a work surface of a work piece for transferring the lacquer from the depressions to the work surface of the work piece, wherein the slit nozzle at its muzzle end includes an upper lip and a lower lip as well as a slit between the upper and lower lips for dispensing lacquer.

An optical device coating assembly is provided. The optical device coating assembly includes a substrate support operable to retain an optical device substrate. The coating assembly further includes a first actuator connected to the substrate support. The first actuator is configured to rotate the substrate support. The coating assembly includes a holder configured to hold a coating applicator against an edge of the optical device substrate when the optical device substrate is rotated on the substrate support and a second actuator operable to apply a force on the holder in a direction towards the substrate support. The second actuator is a constant force actuator.

Devices, systems, and methods of improving paste flow during the manufacture of wind turbine blades are provided. An apparatus for applying adhesive to a composite structure (e.g. wind turbine blade) comprises a paste shoe having a top surface with an aperture to receive a supply of adhesive, and two legs extending downwardly from the top surface and configured to engage a surface of the composite structure to define an interior volume within the paste shoe. A transport mechanism (e.g. wheels, treads) are disposed on each leg to move the paste shoe relative to the composite structure while adhesive is dispensed within the interior volume. A force applicator, applies a force to the paste shoe to maintain a constant interior volume and thus a uniform bead of paste is applied to the composite structure.

A height detection apparatus successively changes the brightness of white light from a first level to a second level in accordance with a position of a Z stage and captures an image of interference light while moving a two-beam interference objective lens relative to a paste film in an optical axis direction, detects, as a focus position, a position of the Z stage where the intensity of interference light is highest in a period during which the brightness of white light is set to the first or second level, for each pixel of the captured image, and obtains the height of the paste film based on a detection result.

The present disclosure provides a method and system by which a precise amount of a viscous fluid sealing compound can be dispensed at required locations through computer vision-based observation of the fluid deposited, its rate and amount of deposition and location; and that the dispensed fluid may be accurately shaped through robotic or other special purpose mechanism motion. The invention enables instant quality inspection of the dispensing process in terms of the locations, amounts and shapes of newly created seals.

A method of dispensing a brushable substance onto a surface comprises (1) with a cartridge positioned inside a sleeve between an inner tubular sleeve wall and an outer tubular sleeve wall, circumscribing the inner tubular sleeve wall, and also positioned between a twist-lock pressure cap, hermetically coupled with the cartridge, and a valve, communicatively coupled with the cartridge, linearly moving an annular plunger, received between an inner tubular cartridge wall and an outer tubular cartridge wall, circumscribing the inner tubular cartridge wall, toward the valve along a first axis to urge the brushable substance from the cartridge, through the valve, and to a brush that is communicatively coupled to the valve; and (2) controlling flow of the brushable substance from the valve to the brush.
