Abstract:
A tool for producing a layer with a micro structured outer surface on a substrate surface is provided. The tool includes an elastic matrix web with a negative of the micro structure to be produced, an elastic pressure roller that is movable over a surface, and at least one guiding element for guiding the elastic matrix web relative to the pressure roller. The pressure roller and the matrix web are arranged in such a manner that when the pressure roller is moved over the substrate surface, the negative on the matrix web faces the substrate surface. In this manner particularly good directional stability and guiding precision of the matrix web can be achieved.
Abstract:
A method of manufacturing an X-ray detector includes: applying a mask having an opening on a substrate on which a plurality of charge detection units are positioned; filling the opening with a paste including a photoelectric conversion material that absorbs X-rays to generate charges; and forming a photoconductive layer from the paste by separating the mask from the substrate. A thickness of the paste within the opening is thicker in an area adjacent to at least one edge among edges of the opening than in areas around other edges.
Abstract:
A method of preparing a conductive metallic layer or pattern includes the steps of applying a metallic nanoparticle dispersion on a support to obtain a metallic layer or pattern, and contacting the metallic layer or pattern with a solution containing an acid or an acid precursor capable of releasing the acid during curing of the metallic layer or pattern. It has been observed that by contacting the metallic layer or pattern with a solution containing an acid or an acid precursor capable of releasing the acid, higher conductivities at moderate curing conditions are obtained.

Abstract:
An inkjet-based process for programmable deposition of thin films of a user-defined profile. Drops of a pre-cursor liquid organic material are dispensed at various locations on a substrate by a multi-jet. A superstrate that has been bowed due to a backside pressure is brought down such that a first contact of the drops is made by a front side of the superstrate thereby initiating a liquid front that spreads outward merging with 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 then occurs after a duration of time. The contiguous film is then cured to crosslink it into a polymer. The superstrate is then separated from the polymer thereby leaving a polymer film on the substrate. In such a manner, non-uniform films can be formed without significant material wastage in an inexpensive manner.
Abstract:
Methods and apparatus for coating substrates. A die can be employed for extrusion coating an elongated substrate, where the die defines a coating cavity therein. The die can comprise a die block having a coating supply channel for supplying a coating material to the coating cavity. The die can further comprise a guide plug and a die plate removably coupled to the die block. The guide plug can comprise a substrate inlet having a non-circular lateral cross-section, and the die plate can comprise a substrate outlet also having a non-circular lateral cross-section. A coating system comprising such a die can operate to coat a substrate where the substrate can be pushed at least partially through the die and contacts the coating material therein.
Abstract:
An apparatus for coating the outer peripheral surface 1a of a pillar structure 1 comprising a smoothing means 10 having a smoothing plate 10a and an elastic body 10b; the elastic body 10 being disposed to be contacted with the outer peripheral surface 1a of the pillar structure 1 to be coated. The coating surface of a coating material supplied to the outer peripheral surface 1a is smoothed between the outer peripheral surface 1a and the elastic body 10b. A method for coating the outer peripheral surface of a pillar structure is also provided. According to the method by using the apparatus, the occurrence of partial uncoating or peeling of the coating and occurrence of cracks in the coating portion during drying after coating can be inhibited since the coating material can be applied thinly and uniformly on the outer peripheral surface, thereby the coating surface is smoothed.
Abstract:
A method for applying a protective coating to a painted workpiece uses an application apparatus which discharges the protective coating as well as streams of compressed air for spreading the discharged protective coating on a surface of the workpiece. The protective coating is fed from an application nozzle unit to the workpiece. The protective coating is uniformly spread over the workpiece by streams of compressed air radiated thereat.
Abstract:
A process for continuous production of self-adhesive articles, wherein a) one polyol component is placed in a container A and essentially one isocyanate component is placed in a container B, b) the polyol component and the isocyanate component are mixed in a mixer, c) the polyurethane composition thus mixed is applied to a backing material which is coated with a pressure-sensitive adhesive composition and moves optionally at constant speed, d) the laminate, comprising first backing material, pressure-sensitive adhesive composition and polyurethane composition, is passed through a heat tunnel, for a time which is less than that required for complete curing of the polyurethane, but sufficient for the curves of storage modulus (G′) and loss modulus (G″) of the polyurethane composition, as a function of curing time, to cross each other, e) the laminate is wound up in a winding station.
Abstract:
A coating composition that can be used in a process for coating a substrate where in a first step a radiation curable coating composition is applied to the substrate and/or a radiation permeable film. Next, the substrate and the film are pressed together in such a way that the coating composition is sandwiched between them. Thereafter, the coating composition is cured by irradiation through the film to obtain a coated substrate. In a subsequent step, the film is removed from the coated substrate. The coating composition applied to the film and/or the substrate is a hot melt composition comprising 20 to 100 wt. % of a radiation curable resin or mixture of radiation curable resins having a viscosity in the range of from 15 to 10,000 mPa.s in the temperature range of from 40 to 150° C.
