Provided is a mask manufacturing method which includes preparing a mask sheet and a frame, stretching the mask sheet, and fixing the stretched mask sheet to the frame, and forming cell openings in the mask sheet fixed to the frame.

The invention solves the problem of protecting aircraft components during finishing. Such components are large and require masking films of vast dimensions which are difficult to handle and position rapidly. The invention relates to films packaged to facilitate transport, and to a method of positioning the packaged films on the corresponding components. The longitudinal and/or transverse portions of the films are packaged by means of at least one opération chosen from among: accordion folding, telescopic folding, gâte folding, roll folding, winding around a mandrel, and winding on itself. The packaged films can have positioning markers on at least one surface and/or tear lines suitable for detaching the portions of film to be separated. The invention also concerns a kit comprising a film and a guide element for guiding the positioning of the film on the component.

A method of manufacturing a metal mask includes calendering a metal material, so as to form a metal mask substrate, where the metal mask substrate includes a surface and a plurality of grooves formed in the surface, and the grooves all extend in a direction. The surface has at least one sampling region, while at least two grooves are distributed in the sampling region, where an average area ratio of the area of the grooves within the sampling region to the area of the sampling region ranges between 45% and 68%.

A substrate plating apparatus is disclosed. The apparatus includes a substrate holder; a plating bath configured to plate a surface of the substrate in a plating solution; a cleaning bath configured to clean the substrate holder and the substrate with a cleaning liquid; an inner shell disposed in the cleaning bath and configured to house the substrate holder holding the substrate therein; and a cleaning liquid supply conduit configured to supply a cleaning liquid into the inner shell to clean the substrate, together with the substrate holder, with the cleaning liquid. The inner shell has an inner surface having an uneven configuration that follows an uneven exterior configuration of the substrate holder holding the substrate.

A kit for use in storm-proofing a structure may include a cartridge comprising an injectable rubber caulk or a malleable rubber paste, a container comprising a viscous liquid rubber composition, a roll comprising a rubberized adhesive tape, a can comprising a sprayable aerosol-based rubberized liquid, a caulking gun configured to engage and dispense contents of the cartridge, a paintbrush, a gap filler tool, a pair of gloves, a pair of safety goggles, and printed instructions. Each component may be combined into a unitary packaging assembly. The injectable rubber caulk, the malleable rubber paste, the viscous liquid rubber composition, the rubberized adhesive tape, and the sprayable aerosol-based rubberized liquid may be safely removed after application and use, or after a storm or natural event has subsided.

A process includes placing a mask over a substrate; delivering liquid film-forming compositions through the mask to the substrate; removing the mask to leave a multilayered raw shape on the substrate; and curing the multilayered raw shape to form the multilayered shaped film product disposed on the substrate. The mask has a delivery surface, an opposite surface and at least one aperture having a design corresponding to the desired shaped film product. The film-forming compositions are delivered through a multistream nozzle. The movement of the mask and the delivery of the first and second liquid film-forming compositions to the mask aperture are controlled to provide a volumetric flow rate of the first and second liquid film-forming compositions to the mask aperture corresponding to the volume of a void. The nozzle is in contact with the delivery surface of the mask.

The present invention includes a diblock copolymer system that self-assembles at very low molecular weights to form very small features. In one embodiment, one polymer in the block copolymer contains silicon, and the other polymer is a polylactide. In one embodiment, the block copolymer is synthesized by a combination of anionic and ring opening polymerization reactions. In one embodiment, the purpose of this block copolymer is to form nanoporous materials that can be used as etch masks in lithographic patterning.
