A method for creating at least one recess, in particular an aperture, in a transparent or transmissive material, includes: selectively modifying the material along a beam axis by electromagnetic radiation; and creating the at least one recess by one or more etching steps, using different etching rates in a modified region and in non-modified regions. The electromagnetic radiation produces modifications having different characteristics in the material along the beam axis such that the etching process in the material is heterogeneous and the etching rates differ from one another in regions modified with different characteristics under unchanged etching conditions.

A fire blasting device for manufacturing a medical glass container prevented from breakage and deformation. A glass container is placed on the outer peripheral surface of each of a first roller and a second roller, which are disposed side by side in such a manner that the axis lines are parallel to each other. The axis line of the glass container is parallel to the axis lines of the first roller and the second roller. The entire outer peripheral surface in an inner surface of the glass container corresponding to a region deteriorated by processing is made to abut on the outer peripheral surface of each of the first roller and the second roller. A flame is ejected from a point burner to the region deteriorated by processing in the inner surface of the glass container while rotating the glass container by rotating the first roller and the second roller around the axis lines.

Apparatus for cleaning contaminated aggregate includes at least one channel arranged in use to receive a liquid containing contaminated aggregate; and first and second banks or groups of at least one jet. The first bank or group of jets is arranged to direct pressurized fluid at the contaminated aggregate in order to agitate the contaminated aggregate against a surface and promote the separation of cleaned aggregate from contaminated aggregate. The second bank or group of jets is arranged to direct and/or urge the cleaned aggregate to a drainage outlet.

A glass-based article including a first surface and a second surface opposing the first surface defining a thickness (t) of about 3 millimeters or less (e.g., about 1 millimeter or less), and a stress profile, wherein all points of the stress profile between a thickness range from about 0.Math.t up to 0.3.Math.t and from greater than about 0.7.Math.t to t, comprise a tangent with a slope having an absolute value greater than about 0.1 MPa/micrometer. In some embodiments, the glass-based article includes a non-zero metal oxide concentration that varies along at least a portion of the thickness (e.g., 0.Math.t to about 0.3.Math.t) and a maximum central tension of less than about 71.5/√(t) (MPa). In some embodiments, the concentration of metal oxide or alkali metal oxide decreases from the first surface to a point between the first surface and the second surface and increases from the point to the second surface. The concentration of the metal oxide may be about 0.05 mol % or greater or about 0.5 mol % or greater throughout the thickness. Methods for forming such glass-based articles are also disclosed.

A vehicle pane includes a glass substrate with elemental silver applied thereon discontinuously, as one or a plurality of lines, wherein the elemental silver has a coating that contains a thiol and/or a silicone resin and/or a silicate.

The present invention includes a method of a low cost, reliable novel broadband inductor that can be used with a capacitor to form a broadband filter.

Described herein are articles and methods of making articles, for example glass articles, comprising a thin sheet and a carrier, wherein the thin sheet and carrier are bonded together using a modification (coating) layer, for example a coating layer comprising a cationic surfactant or a coating layer comprising an organic salt, and associated deposition methods. The modification layer bonds the thin sheet and carrier together with sufficient bond strength to prevent delamination of the thin sheet and the carrier during high temperature (? 500° C.) processing while also preventing formation of a permanent bond between the sheets during such processing.

Methods, systems, devices, and substrates are described. In some examples, an apparatus may include optical components configured to adjust an input to a laser cutting optic for modifying a substrate (e.g., an optically transmissive substrate). In some examples, the optical components may include a beam deflector, a first optic configured to output a first laser beam with a first beam width, and a second optic configured to output a second laser beam with a second beam width. In some examples, the beam deflector may modify an optical path of a pulsed laser (e.g., through the first optic or through the second optic), which may result in an input to the laser cutting optic having a beam width corresponding to the first optic or the second optic. The different input beam widths may modify a line focus intensity of an output of the laser cutting optic when modifying the substrate.

A substrate, a method for separating the substrate, and a display panel are provided. The substrate is disposed on a glass substrate. The substrate includes a substrate layer and a sacrificial layer. The sacrificial layer disposed between the substrate layer and the glass substrate, and is configured to share the force exerted on the substrate layer when the substrate is being separated from the glass substrate.
