摘要:
An improved way to impart antireflection properties to a light transmissive substrate and, at the same time, achieve a durable surface and electrical conductivity is disclosed. A stack of at least two sputter-deposited light transmissive inorganic layers, one of which being electrically conductive and having a high index of refraction with the one above it (relative to the substrate being antireflected) having a low index of refraction, in combination with a thin lubricating overlayer comprising a solvent-soluble lubricant such as a solvent-soluble fluoropolymer can achieve this desired combination of properties.

The adhesion to plastic substrates (112) of thick layers of functional metals (116) having an oxide heat of formation that is greater than -40,000 calories/gram atom of metal, such as silver, copper, gold, and the like, is improved if a thin layer of a metal having an oxide heat of formation of less than -50,000 calories/gram atom of metal is present as an adhesion-promoting primer layer metal has a melting point greater than 1100 °C, it should be present as the metal or as a substoichiometric oxide. When the primer layer metal (114) has a melting point less than 1100 °C, it may be present as the metal, as a substoichiometric oxide, or as a full stoichiometric oxide. Processes for preparing these materials using sputter-depositing and reflectors incorporating these materials are also disclosed.

Structures (10) de vitrage isolant à vitres multiples présentant une efficacité d'isolation thermique exceptionnelle. Les nouvelles structures (10) à vitres multiples comprennent deux feuilles de vitrage (14 et 16) rigides et parallèles, espacées par une pièce d'écartement (22) intérieure en polymère alvéolaire, à cellules fermées, de faible conductivité thermique. Selon un mode de réalisation préféré, les feuilles de vitrage (12, 14, 16 et 18) sont disposées en une structure (10) à quatre vitres remplie d'un gaz inerte, et obturée à l'aide d'un ruban (46) continu imperméable au gaz recouvrant un matériau d'étanchéité (44) durcissable à haut module. Des procédés de fabrication des nouvelles structures (10) de vitrage sont également décrits.

Un appareil (10) de déposition par pulvérisation d'une couche métallique sur un substrat (12) de grande étendue latérale comprend un support du substrat, une station de déposition (14), un assemblage capteur en aval (58) et une unité de commande informatisée. La station de déposition comprend une cathode (16, 22) et des anodes (28, 30) agencées sur la largeur du substrat (12). Une alimentation en gaz d'une pluralité de zones est assurée par une chambre commune de distribution (48) pourvue d'une pluralité d'orifices d'admission, qui associés les uns aux autres, couvrent toute la largeur du substrat sur lequel on veut déposer une couche à mince pellicule. Le courant de gaz est dirigé par chaque anode dans la région du plasma et est commandé individuellement dans le cas de chaque zone. L'assemblage capteur en aval (58) comprend pour chaque zone un ensemble (62) de contact à quatre points pourvu de quatres roues électroconductrices (64, 66, 68, 70). Deux de ces roues servent à appliquer un courant à la mince pellicule et les deux autres à capter sa résistance. Ces informations sont fournies à l'ordinateur afin d'être utilisées pour commander les courants de gaz dans la station de déposition, zone par zone.
摘要:
A method of automatically mounting a sheet from a cutting table onto a spacer frame of an insulating glass unit begins with identifying a position and orientation of a specified sheet on the cutting table and moving a robotic sheet pickup apparatus to a corresponding position to that identified for the sheet. An edge of the specified sheet is lifted off of the table, beginning with mechanical suction that brings a corner of the sheet to within proximity of a primary vacuum suction of the pickup apparatus. In particular, the pickup apparatus may have a substantially planar platen with a set of channels coupled to a vacuum source. Once the sheet is fully picked up by vacuum suction, the sheet is laid upon a top surface of a tilt table, which can be simply the platen inverted. The table (or platen) is tilted to bring a corner of the sheet to abut against physical fences. Once the position and orientation of the sheet is so known, the sheet is oriented to correspond to a frame, and attached thereto.
摘要:
'Corrosion' performance of an optical filter is enhanced when a relatively thick zinc-based film (30, 32 and 34) functions as a seed layer for a subsequently formed silver-based film (18, 20 and 22). At least two pairs (12, 14 and 16) of dielectric and metallic layers are included within the optical filter, where the zinc-based film is a second film of the dielectric layer and where the silver-based film is the metallic layer. The zinc-based film has a zinc content of at least 80 percent and has a thickness of at least 15 nm. In order to further improve the corrosion performance, gold may be incorporated into the silver-based film.
摘要:
Conductive micro traces (64) are formed on a coated or uncoated substrate (28) in order to achieve a combination of target optical properties and target electrical capabilities. For the coated substrate, the coating (100) may be formed before or after the conductive micro traces. Thecoating may be designed for providing IR filtering or reductions in reflected light and color shift, while the conductive micro traces may be used for EMI shielding or to provide current-carrying capability, such as when used as heaters. In another embodiment, the conductive micro traces are formed on an uncoated flexible transparent substrate and have a width of less than 25 microns, such that the conductive micro traces are capable of achieving their intended purpose while maintaining a high visible light transmissivity. The conductive micro traces may be formed using various approaches, such as the use of electroplating techniques or the use of inkjet printing techniques.
