A device for recording information in a data carrier, comprising a data carrier receptacle for partially receiving the data carrier in a planar manner; a data carrier cover arranged relative to the data carrier receptacle, which is designed for holding the data carrier between the data carrier receptacle and the data carrier cover; a laser source for the controlled emission of a laser beam designed to effect irreversible changes of the data carrier with the laser beam; and a mount that receives the data carrier receptacle to be pivotable about a pivot axis. The data carrier receptacle has two or more positions, that allow the data carrier receptacle to be received in the mount in such a way that the data carrier receptacle can be repositioned about the pivot axis in a pivotable manner.

A cylindrical battery includes a bottom-closed cylindrical exterior package can which receives an electrode body. A lead connected to one of a positive electrode and a negative electrode of the electrode body is extended from the electrode body and is welded to a bottom portion of the exterior package can. When the bottom portion is viewed from the outside of the exterior package can, at least a part of the welding portion between the lead and the bottom portion formed by a molten mark is formed outside of a concentric circle of the bottom portion which has a diameter equivalent to the width of the lead.

A processing performance confirmation method for a laser processing apparatus that processes a workpiece with a laser beam of a wavelength having absorption in the workpiece. The method includes a holding step of holding the workpiece by a chuck table of the laser processing apparatus, a processing mark forming step of moving the workpiece and a condensing point of the laser beam relative to each other in a predetermined direction intersecting a thickness direction of the workpiece at right angles while changing the condensing point in height, thereby to form a processing mark on an upper surface of the workpiece, a imaging step of imaging a plurality of regions of the processing mark formed in the processing mark forming step, and a confirmation step of confirming processing performance of the laser processing apparatus based on images acquired in the imaging step.

A method for removing a coating of a surface of a wheel. The wheel is provided with screw channels and with a centrally positioned hub opening. Each of the screw channels and the central opening is delimited by an area from which the coating is to be removed. Each of the areas extends annularly around one of the screw channels or around the hub opening. The method is implemented using a laser beam generated by a laser source. The method comprises the steps of positioning an extraction opening directly beneath a center of one of the screw channels or the central opening surrounded by the area, moving the laser beam over the area without masking the area (7) from which the coating is to be removed, and extracting gases and particles produced during the step of removing the coating directly through one of the screw channels or the central opening.

The present application relates to a device for generating a jet of liquid propagating along a jet axis, said jet of liquid guiding a laser beam. The device comprises a wall element having a central opening, wherein a nozzle holder comprising a nozzle and a window element comprising the window are arranged one above the other within said central opening, said nozzle holder and said window element being spaced from each other along said jet axis, said spacing defining an acceleration chamber, wherein said connection passage and said distribution chamber are formed within said nozzle holder.

A parts fabrication apparatus has a staging fixture that is configured to position at least a portion of a molded plastic assembly that has a connective runner portion with at least one molded part extended from the connective runner portion by a severable gate portion. A laser source is energizable to direct toward the severable gate portion, from a laser output aperture positioned beneath the staged plastic assembly, a coherent light beam having sufficient energy for melting the gate portion and releasing the molded part along a drop path. A support is disposed to deflect the drop path of at least a portion of the released molded part in a direction away from the coherent light beam.

Disclosed is a method and an apparatus to process a workpiece including producing a first beam of laser energy characterized by a first spatial intensity distribution. A first workpiece is processed using the first beam of laser energy to form a plurality of features at a first distance between the scan lens and the first workpiece and forming a second features at a second distance. The method includes determining which of the plurality of features has a shape that most closely resembles the shape of the first spatial intensity distribution and setting a process distance as the distance that produced that feature. Using this process distance, a surface of a second workpiece is processed using second beam of laser energy with a second spatial intensity distribution.

A laser oscillator support table includes a base, a fixed plate supported over the base with intermediary of a Z-axis direction movement unit, and a Y-axis direction moving plate mounted on the fixed plate, movable orthogonal to an X-axis direction. An optical path direction of the beam emitted from a laser oscillator supported by the laser oscillator support table is defined as the X-axis direction. The laser oscillator support table further includes a rotating plate that is mounted on the Y-axis direction moving plate rotatably around a rotation center pin fixed to the Y-axis direction moving plate and supports the laser oscillator, a Y-axis direction movement unit that moves the Y-axis direction moving plate in the Y-axis direction, and a rotational movement unit that rotates the rotating plate around the rotation center pin in a plane parallel to a plane formed by the X-axis direction and the Y-axis direction.
