摘要:
The invention relates to a glass sheet (2) comprising a symbol (8) marked inside the glass, said symbol forming a code. The symbol is marked in at least two dimensions including the thickness of the glass sheet, parts of the symbol being marked at different depths in the thickness of the glass sheet.
摘要:
A method for selectively removing portions of a protective coating from a substrate, such as an electronic device, includes removing portions of the protective coating from the substrate. The removal process may include cutting the protective coating at specific locations, then removing desired portions of the protective coating from the substrate, or it may include ablating the portions of the protective coating that are to be removed. Coating and removal systems are also disclosed.
摘要:
A method for removing a metal from a single-thread fabric for making a pattern, characterized in that said single-thread fabric is a square-mesh metallized and etching laser made fabric.
摘要:
Self-retaining suture systems including a suture thread bearing a plurality of laser-cut retainers are disclosed. A laser system allows the creation of retainers and self-retaining suture systems in configurations which are difficult and/or impossible to achieve using mechanical cutting technology.
摘要:
Apparatus and methods for forming fine scale structures (4, 4′, 4″, 5, 6, 7, 8) in the surface of a dielectric substrate (3) to two or more depths are disclosed. In an example, the apparatus comprises a first solid state laser (12) arranged to provide a first pulsed laser beam (13), a first mask (16) having a pattern for defining a first set of structures (4, 6, 7, 8) at a first depth, a projection lens (17) for forming a reduced size image of said pattern on the surface (3) of the substrate and a beam scanner arranged to scan said first pulsed laser beam (13) in a two-dimensional raster scan relative to the first pattern to form a first set of structures (4, 6, 7, 5) at a first depth in the substrate, wherein the first or a further solid state laser is arranged to form a second set of structures (8) at a second depth in the substrate (3).
摘要:
Process for producing a laminated glass pane made up of a base pane (15), a first laminating film (16), a coated polymer film (1) with a coating (1.2), a second laminating film (17) and a top pane (18) having at least one sensor window (19), comprising steps a) to d), wherein a) the coated polymer film (1) with a coating (1.2) is tensioned pointing upward by way of a vacuum table (3), b) at least one region (1.3) from which the coating is removed is produced on the coated polymer film (1) by means of laser treatment, c) the first laminating film (16) is arranged on the base pane (15), the coated polymer film (1) is arranged on the first laminating film (16), the second laminating film (17) is arranged on the coated polymer film (1) and the top pane (18) is arranged on the second laminating film (17), and d) the arrangement is autoclaved, wherein the region (1.3) from which the coating is removed is produced by way of glass plates (2.1, 2.2) with which the vacuum table (3) is equipped.
摘要:
A repair method for repairing a component (6a) of a gas turbine engine (10). The method comprises first and second steps. The first step comprises directing an energy beam toward the component (6a) to ablate a first region (54) of material to form a gap extending through the component (6a) between a repair region (58) a base region (58) of the component, wherein subsequent to the first step the repair region (58) and base region (56) are joined by a connecting portion (60). In the second step, an energy beam is direct toward the component (6a) to ablate the repair region (58) to remove the repair region (58) from the component (6a).
