The method and system also cuts through both the first and second layers along the inlet portion of the outline. The method and system also cuts through both the first and second layers along a path that closes the third side of the inlet portion.

A method for forming a laser-marked chain assembly. The method includes: coupling a plurality of chain links to one another for form a length of chain having a first and a second end; marking an outer plate of at least one of the plurality of chain links with a laser; and coupling the first and second ends to one another to form the laser-marked chain assembly.

A sheet of material that is marked in a predetermined pattern with a pulsed laser on its outer surface. The sheet material is a layered material that has an outer edge and an inner edge separated by a core. There is a first layer comprising a first material beginning at the outer edge and extending into the core and there is a second layer containing the second material within the core. The outer surface further has a patch, that is a region of the outer surface where the second material is disposed at the outer surface, and at least a portion of the laser marks are disposed on the patch.

A semiconductor device that is a facedown mountable, chip-size-package type semiconductor device, the semiconductor device including: a semiconductor substrate; and a metal layer that is disposed on the semiconductor substrate and is exposed to outside. One or more marks are provided on an exposed surface of the metal layer. The one or more marks each include an outline portion defining an outline of the mark, and a central portion located inward of the outline portion. In a plan view of the exposed surface of the metal layer, the outline portion has a color different from at least one of a color of the central portion or a color of a base portion that is a portion of the exposed surface of the metal layer on which the one or more marks are not provided.

Provided is a laser mark printing method and a method of producing a laser-marked silicon wafer that can reduce the machining strain left around dots constituting a laser mark. In a method of printing a laser mark having a plurality of dots on a silicon wafer, the plurality of dots is formed using laser light having a wavelength in the ultraviolet region.

A method for creating a pattern figure formed of pattern points, in a workpiece, using a laser device of a machining device comprises reading in first position data, which define positions of first pattern points on the workpiece, wherein the first pattern points are associated with a first portion of a polyline of the pattern figure associated with the first pattern, introduction of the first pattern points into the workpiece taking place while the machining device is located in a first position, a detection of a course of an end of the first portion of the polyline, a continuation of the course of the end of the first portion of the polyline, and an introduction of second pattern points of a second portion of the polyline into the workpiece using the continued course, while the machining device is in a second position.

A method for decorating a given part is designed to print designs onto a coat layer deteriorating the coat layer on the surface of the given part. In the coat layer-forming process, in spreading the metallic-coating material containing aluminum flake onto the surface of the resin compact, the coat layer is formed on the surface of it. In a laser-printing process, a laser is irradiated on the condition of being able to maintain the same state of the coat layer before and after irradiating the laser, so as to reduce the aspect ratio of the micronized-metallic powder, which is the average value of the ratio of the maximum dimension of the micronized-metallic powder to the average value of the minimum dimension of the micronized-metallic powder, which laser irradiation eventually thermally deforms the first scale-shaped micronized-metallic powder into a spherical shape in the coat layer to print designs on the film.

Described is a method of providing a rubber article (100) with a digital code pattern (102), wherein the rubber article (100) comprises a cured polymer material (104), the method comprising: Generating, e.g. by means of electromagnetic radiation (110), a digital code pattern (102) in the cured polymer material of the rubber article, the digital code pattern (102) comprising a first surface portion (106) and a second surface portion (108) having different optical reflectivity. Generating the digital code pattern (102) may include generating protrusions (114) or holes (126) in the second surface portions (108). The digital code pattern (102) may identify the rubber article (100) e.g. within a batch of rubber articles. Described is also a rubber article (100) comprising a digital code pattern (102), a rubber article marking device and a computer program product for controlling a rubber article marking device.

Boldface printing having a sufficient line width is more easily implemented as compared with the related art. A laser marking apparatus includes a laser light output section, a laser light scanning section, a storage section, and a marking control section. The marking control section scans UV laser light along an outer scanning line farther from a center line of a line element of a character corresponding to print data for boldface than an inner scanning line prior to the inner scanning line closer to the center line for scanning lines adjacent to each other in a direction in which the line element of the character becomes thick among a plurality of the scanning lines forming the print data for boldface.
