The present invention relates to a method of aligning comprising providing a support, applying a transparent layer, patterning at least the transparent layer to produce a pattern and an alignment feature capable of scattering light, illuminating the support and the transparent layer with oblique lighting, providing an analysis system capable of sensing scattered light from the alignment feature and referencing, sensing the scattered light from the alignment feature; referencing the scattered light from the alignment feature to a position on said support; and aligning a second operation to the position.

Laser etched fiducials in roll-roll display

The invention relates to a web material comprising a carrier sheet, a continuous pragmatic sheet and an adhesive layer wherein the adhesive layer is between the carrier sheet and the pragmatic sheet, the adhesive layer more strongly adheres to the pragmatic sheet and the pragmatic sheet is narrower than the carrier sheet wherein the side of the carrier sheet in contact with the adhesive is reflective.

Tack free cauterized edge for pressure sensitive adhesive web

An apparatus for laser marking indicia on a moving photosensitive web by impinging laser energy upon the moving web with a laser printer device. The laser printer device is provided with a nozzle element that concentrates beams of radiation onto the web with substantially reduced incidences of fog spots on the web. The nozzle element extends circumferentially, substantially around a laser beam tube and the predetermined optical path defined by laser beams emanating from the laser beam tube.

Apparatus for laser marking indicia on a photosensitive web

A nozzle element for laser marking indicia on a moving photosensitive web substantially reduces fog spots on the web caused by impinging laser energy. The nozzle element is configured to conform to the outlet end of the laser beam tube to eject particulates through vacuum outlet port.

Nozzle element adaptable to a laser beam tube used in laser edge marking equipment

A method of controlling peak power of a radiant energy emitting system, such as lasers adapted for use in laser edge marking apparatus, reduces fog spots on the web caused by impinging laser energy. A laser printer has an attenuating member provided in the optical path of a laser beam tube for controlling peak power to each one of the plurality of lasers.

Method of controlling peak power of a radiant energy emitting system

An apparatus for laser marking indicia on a moving photosensitive web substantially reduces fog spots on the web caused by impinging laser energy. A laser beam attenuating member arranged in the laser beam tube enables control of peak laser beam power thereby significantly reducing the incident of fog spots on the film surface.

A dielectric member with an integral, electrically conductive surface is made by molding a substrate from a zirconia alloy powder using a tape casting process. The resulting green substrate is sintered and after sintering may be cut to the final desired size and shape. Once the insulating ceramic substrate has been formed, the surface of the substrate is modified using infrared laser energy. Through the impingement of infrared laser radiation upon the surface of the ceramic substrate, an electrically conductive region is produced on the surface of the substrate. In such manner, the entire surface can be made electrically conductive or a particular pattern can be traced. As an integral part of the substrate, the surface will not delaminate from the substrate. Further, because the modified surface region and the substrate are both a zirconia, the coefficients of thermal expansion of the substrate and the modified surface region will be closely matched.
