摘要:
Un filtre EMI/RFI composite multicouche monté devant des écrans d'affichage visuel de tubes à rayons cathodiques est construit avec un substrat en plastique (22) ayant un revêtement extérieur dur de diffusion (21) et un métal comprenant une couche de conduction et de transmittivité. De préférence, le métal se présente comme un empilement déposé par pulvérisation de diélectrique-métal-diélectrique (31, 32, 33). Le filtre est particulièrement utile pour empêcher les interférences provenant du tube à rayons cathodiques d'atteindre des installations sensibles de navigation ou autres récepteurs sensibles.
摘要:
The invention relates in particular to a method for stretching a membrane (4), arranged between two panes (2, 3), of an insulating glazing unit (1). For effective stretching, it is proposed that the membrane (4) is exposed to a conditioning medium passed through an interspace (6, 7) between the panes (2, 3) and the membrane (4).
摘要:
A multi-layer antireflection coating (20) is formed to include successive layers of a medium refractive index material (22), a high refractive index material (24), and a low refractive index material (26). The medium refractive index layer is hydrogenated in order to tailor the refractive index of the material to below 1.99 and to increase clarity in transmission. Preferably, the hydrogen atomic concentration is at least 7 percent, more preferably exceeds 9 percent, and most preferably exceeds 18 percent. The three layers combine to form a three-layer antireflection coating, but the hydrogenation may be used in antireflection coatings having a greater or lesser number of layers. In use, the medium refractive index layer is closest to the substrate (12) for which antireflection is desired. Preferably, the medium refractive index layer is formed of an indium oxide, a tin oxide or a zinc oxide, or an oxide of an alloy in which indium, tin or zinc is a major constituent.
摘要:
A reflection control member includes a multilayer stack that is adhered to a substrate using a primer layer to promote adhesion. The multilayer stack includes pairs of layers in which the first layer is a grey metal and the second layer is a substantially transparent material. In the preferred embodiment, the grey metal is nickel chromium and the transparent layer is a silicon oxide. For each pair of layers, the grey metal is nearer to the surface of the substrate for which antireflection is a concern. The primer layer has a thickness of less than 50 angstroms. Although the primer layer is deposited in an essentially oxygen-free environment, it may oxidize following deposition.
摘要:
Multipane, insulating glazing structures having exceptional thermal insulation performance are provided. The multipane structures comprise two substantially parallel rigid glazing sheets (12, 18) spaced apart by an interior spacer (20) which includes a physically stable body (22) of low thermal conductivity, closed cell, foamed polymer.
摘要:
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 DEG 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 DEG 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.
摘要:
Visually transparent, preferably color corrected, infra-red reflecting films (80) are disclosed for solar heat control. The films employ Fabry-Perot sandwich interference filters (12) which are characterized by having two or more transparent layers (16, 16', 16'') of sputter-deposited metal such as silver separated by dielectric spacer layers (18, 18') and optionally boundary layers (20, 22). Methods for producing these materials by sputtering techniques as well as glazing materials (81-84) incorporating these films are disclosed, as well. In preferred embodiments, these films are laminated into glazing structures (81-84).
摘要:
Anti-reflective composites (84) comprising carbon-based polymer substrates (86),such as polyesters, are antireflected by applying to the substrates one or more discontinuous layers of inorganic materials (88, 92) having an index of refraction greater than that of the substrates.
