Abstract:
The present invention relates to a process for depositing an anti-reflective layer on a transparent flat substrate comprising the steps of providing a liquid coating composition comprising at least one solvent, at least one inorganic oxide precursor, and at least one pore forming agent; applying the coating composition to the substrate; drying the applied coating layer, and curing the coating layer; wherein during drying a gas flow is provided to the substrate at a flow rate of between 0.2 and 6 m/s. The advantage of this process is that defects visible in edge areas of the coated substrate can be significantly reduced.

Abstract:
A device and a method which is capable of uniformly coating, without waste, any flow passages formed in a raw material with a slurry even if a slurry having high viscosity is fed thereto by an amount required for the use of coating without excess and shortage. When the slurry (S) fed to one end of the base material (M) in which a large number of flow passages (2 . . . ) are formed parallel with each other is forced into the flow passages (2 . . . ) by an air pressure to coat the inner walls (2w) of the flow passages, the slurry (S) is fed from a slurry feeding device (6) by a required amount to a slurry storage part (5) formed at the upper surface part of the base material (M) disposed so that both ends of the flow passages (2 . . . ) can be opened in the upper and bottom surfaces thereof. Then, before the slurry (S) is forced into the flow passages (2 . . . ), a centrifugal force and vibration are allowed to act on the slurry (S) by a liquid level uniformalizing mechanism (7) to uniformalize the level of the slurry.
Abstract:
A method for producing a silica aerogel film by hydrolyzing and polymerizing alkoxysilane in the presence of a base catalyst to prepare an alkaline sol, adding an acid catalyst to the alkaline sol to carry out further hydrolysis and polymerization to prepare a first acidic sol, hydrolyzing and polymerizing alkoxysilane in the presence of an acid catalyst to prepare a second acidic sol, applying a mixture of the first and second acidic sols to a substrate, and drying it.
Abstract:
A method of fabricating an elastomeric structure, comprising: forming a first elastomeric layer on top of a first micromachined mold, the first micromachined mold having a first raised protrusion which forms a first recess extending along a bottom surface of the first elastomeric layer; forming a second elastomeric layer on top of a second micromachined mold, the second micromachined mold having a second raised protrusion which forms a second recess extending along a bottom surface of the second elastomeric layer; bonding the bottom surface of the second elastomeric layer onto a top surface of the first elastomeric layer such that a control channel forms in the second recess between the first and second elastomeric layers; and positioning the first elastomeric layer on top of a planar substrate such that a flow channel forms in the first recess between the first elastomeric layer and the planar substrate.
Abstract:
A method for improving the adhesion of an amine-containing organopolysiloxane composition to a substrate which comprises coating the substrate with an amine-containing organopolysiloxane composition and thereafter heating the coated substrate to an elevated temperature prior to or during exposure to moisture and carbon dioxide in excess of that present in the atmosphere.
