Method and apparatus for laser scribing glass sheet substrate coatings

Title: Method and apparatus for laser scribing glass sheet substrate coatings

Abstract

A method and apparatus (42) for laser scribing coatings on glass sheet substrates by conveying the substrate adjacent a laser source (83) that provides a pulsed laser beam (84) with a wavelength at a near-infrared fundamental frequency and having a frequency in the range of 50 to 100 kilohertz and a pulse duration in the range of 8 to 70 nanoseconds, and by reflecting the beam by an XYZ galvanometer controlled mirror system (90) toward an uncoated surface of the substrate for passage therethrough to the coating on the other surface to provide overlapping ablations through the coating and scribing at a speed of at least 1000 millimeters per second.

Apparatus and method for depositing coating onto porous substrate

Patent Isenberg, Arnold O [Forest Hills Boro, PA]; Zymboly, Gregory E [Penn Hills Township, Allegheny County, PA]

Disclosed is an apparatus for forming a chemically vapor deposited coating on a porous substrate where oxygen from a first gaseous reactant containing a source of oxygen permeates through the pores of the substrate to react with a second gaseous reactant that is present on the other side of the substrate. The apparatus includes means for controlling the pressure and flow rate of each gaseous reactant, a manometer for measuring the difference in pressure between the gaseous reactants on each side of the substrate, and means for changing the difference in pressure between the gaseous reactants. Also disclosed is amore »« less

Method and apparatus for coating a patterned thin film on a substrate from a fluid source with continuous feed capability

Patent Burrows, Paul E [Kennewick, WA]; Sapochak, Linda S [Kennewick, WA]

A method and apparatus for forming patterned coatings of thin film, non-polymerizable compounds on a substrate. A mixture of the non-polymerizable compound and a liquid carrier is pumped into the interior of a heated evaporation box having an internal temperature sufficient to convert substantially all of the non-polymerizable compound and liquid carrier to a gaseous form. The non-polymerizable compound and liquid carrier are then removed from the evaporation box via exit slit in the evaporation box. Adjacent to the exit slit, and maintained in a vacuum, is a first substrate upon which the non-polymerizable compound condenses. The first substrate ismore »« less

Coated substrate apparatus and method

Patent Bao, Zhenan; Diao, Ying; Mannsfeld, Stefan Christian Bernhardt; ...

A coated substrate is formed with aligned objects such as small molecules, macromolecules and nanoscale particulates, such as inorganic, organic or inorganic/organic hybrid materials. In accordance with one or more embodiments, an apparatus or method involves an applicator having at least one surface patterned with protruded or indented features, and a coated substrate including a solution-based layer of objects having features and morphology attributes arranged as a function of the protruded or indented features.
