A patterning device performs patterning in manufacture of a display panel in which thin films including an organic film are laminated above a substrate. The patterning device includes a chamber, light transmissive plates, and a laser emitter. The chamber has a light transmissive window including a first light transmissive plate through which a laser beam is transmitted and accommodates a thin film laminated substrate. A second light transmissive plate through which the laser beam is transmitted is in the chamber between the first light transmissive plate and the thin film laminated substrate at a position spaced away from the thin film laminated substrate. The laser emitter is outside the chamber and emits the laser beam towards the thin film laminated substrate, through the first light transmissive plate and the second light transmissive plate, to irradiate and remove a portion of the thin film.

Welded headgear sections can be produced by using a weld tool having pins protruding from a weld region contact surface to deliver high-frequency electromagnetic energy to a weld region defined by overlapping top and bottom headgear straps. The pins fully penetrate the top strap and at least partially penetrate the bottom strap. The pins concentrate the electromagnetic energy to achieve a weld joint of acceptable weld strength and aesthetic appeal.

An edible decoration is laser kiss cut from an edible decorating sheet by optically sensing at least one printed edible design on the edible decorating sheet relative to a laser cutting tool coordinate system and driving a laser along a circuit of cutting locations defined in the laser cutting tool coordinate system. The laser beam forms a separation channel by laser ablation of at least a portion of the edible decorating sheet at the cutting locations while leaving intact the non-adhesive releasable backing upon which the edible decorating sheet rests.

Provided are a cleaning device and a method for cleaning a vulcanization mold. At the time of cleaning a molding surface of a vulcanization mold by irradiating with a laser beam from a laser head, an inert gas is supplied from a supply nozzle and an irradiation range of the molding surface irradiated with the laser beam is brought into an atmosphere of the inert gas.

A method of manufacturing a waterproof strapped accessory and a waterproof strapped accessory formed according to the disclosed method are provided. Using a thermal laser cutter, a raw thermal polyurethane-coated nylon webbing material is cut, obtaining a desired shape of a strapped accessory. Holes may be cut through the strapped accessory using the thermal laser cutter. The thermal laser cutter seals the cut edges of the strapped accessory as well as any hole cut by the thermal laser cutter, rendering all or most edges waterproof. The strapped accessory is then inspected, and any unsealed edges sealed with a thermal rod. The strapped accessory is then cleaned of any residue and allow to cure under predetermined environmental conditions for a predetermined amount of time. Keepers and/or any desired hardware may be affixed to the strapped accessory. Indicia may also be imparted onto the strapped accessory by the thermal laser cutter.

A glass sheet processing method is provided for irradiating a laser beam on a glass sheet and forming a cleavage in the glass sheet with thermal stress. If each of an irradiation area of the laser beam on the surface and an irradiation area of the laser beam on the back face of the glass sheet includes a peak position of a power density of the laser beam, each irradiation area has an asymmetrical power density distribution that is asymmetrical with respect to a reference line that passes through the peak position and is parallel to a moving direction of the peak position. If each irradiation area has no peak position, each irradiation area has an asymmetrical shape that is asymmetrical with respect to a reference line that passes through a centroid position of the irradiation area and is parallel to a moving direction of the centroid position.

A series of laser pulse bundles or bursts are used for micromachining target structures. Each burst includes short laser pulses with temporal pulse widths that are less than approximately 1 nanosecond. A laser micromachining method includes generating a burst of laser pulses and adjusting an envelope of the burst of laser pulses for processing target locations. The method includes adjusting the burst envelope by selectively adjusting one or more first laser pulses within the burst to a first amplitude based on processing characteristics of a first feature at a target location, and selectively adjusting one or more second laser pulses within the burst to a second amplitude based on processing characteristics of a second feature at the target location. The method further includes directing the amplitude adjusted burst of laser pulses to the target location.

The present disclosure provides for systems and methods for removing markings from pavement. In general, the present disclosure provides for methods of using thermal ablation for effectively removing pavement stripe markings without causing excessive damage to the pavement surface.

A thermal interface material and method of making the same includes growing a carbon nanotube array on a first substrate and brazing the distal ends of the carbon nanotube array to a second substrate using a braze material. In at least one embodiment, the braze material includes active elements. The method further includes performing the brazing process in an inert or vacuum atmosphere.
