To provide a laser annealing apparatus which is high efficiency of irradiation energy and capable of achieving uniformity in density of irradiation energy in a region irradiated with a laser beam.

SOLVING MEANS

Scheduled treatment regions of a treatment film are each defined in the form of a strip extending in a scanning direction. Irradiation surface areas of line beams are oriented to be inclined relative to the scanning direction within respective scheduled treatment regions.

Provided is a laser processing machine including a laser head capable of irradiating a workpiece with laser beam, a belt conveyor provided away in an irradiation direction of the laser beam, and a control unit configured to control operations of the laser head and the belt conveyor. The laser head is configured to be movable along at least a rotating direction of the belt conveyor. The control unit is configured to control, in a case where a moving direction and a moving speed of the laser head match the rotating direction and a rotating speed of the belt conveyor during the irradiation with the laser beam, the operation of at least one of the laser head and the belt conveyor in order to avoid the matching.

A system and process for fabricating motor laminations from sheet material. Various embodiments of the disclosure combine a separation process with one or both of a cutting and a scoring process that outlines the laminations prior to the separation process. In some embodiments, the separation process is a punching process and is integrated with the stacking of the motor laminations to form the stator core. In addition, a system and process where the cut and/or scored portion of the sheet material is subjected to flattening process prior to the separation process is disclosed. Performing the flattening process prior to the separation process has the effect of streamlining the process, in that the sheet material can be easily handled and conveyed from the scoring process, through the flattening process, and to the separation and stacking process, without need for separate handling of the laminations.

Provided is a mask changing unit for a laser bonding apparatus, and more particularly, a mask changing unit for a laser bonding apparatus, wherein the mask changing unit supplies or changes a mask to or in the laser bonding apparatus for bonding a semiconductor chip to a substrate by using a laser beam. The mask changing unit for a laser bonding apparatus, a plurality of masks that are used in performing laser bonding of a semiconductor chip to a substrate while the semiconductor chip is being pressed may be easily supplied to the laser bonding apparatus or changed in the laser bonding apparatus.

The present invention discloses a method to calibrate a laser cutting machine without stopping the production. The method is adapted to laser cutting machine which use a conveyor belt to convey the sheets while cutting them with the laser. The method allows to place calibration marks at locations on the sheet that are convenient according to the production job, thereby minimising the waste of material.

A cutting apparatus comprising a cutting table and a first cutting material belt movably supported about the cutting table about a first roller and a second roller. A second cutting material belt is removably supported above the first cutting material belt about the first roller and a third roller, wherein the second roller is intermediate the first roller and the second roller.

A laser processing apparatus includes a cylindrical body having an opening on a circumferential surface around which a thin plate to be processed is wound obliquely, a thin plate transfer for transferring a thin plate wound around the cylindrical body in the longitudinal direction of the thin plate, a motor having a rotation axis arranged coaxially with a central axis of the cylindrical body, a reflecting member fixed to a rotating shaft of the motor, a laser light emitting means for emitting pulsed light. The apparatus continuously opens through holes in the thin plate.

A marking device, a medium, a container, and a marking method. The marking device includes a first marker including a first optical system having a first focal point, the first marker being configured to concentrate a first light onto a first area of a non-planar portion of a medium to perform marking on the first area, the non-planar portion including a plurality of areas including the first area and a second area, and a second marker including a second optical system having a second focal point. The second marker is configured to concentrate a second light onto the second area to perform the marking on the second area, and the second focal point of the second optical system is different from the first focal point of the first optical system in a direction parallel to a central axis of the first optical system.

A drawing method for drawing a wiring pattern on a substrate is provided. The wiring pattern includes first regions, in which a pattern in the width direction of the substrate changes in the longitudinal direction of that, and second regions, in which a pattern in the width direction does not change in the longitudinal direction. The drawing data includes two-dimensional image data representing a two-dimensional pattern of the first regions, one-dimensional image data representing a one-dimensional pattern in the width direction of the second regions, and information representing lengths of the second regions. The method includes: drawing the pattern of the first regions by scanning the beam based on the two-dimensional image data and conveying the substrate; and drawing the pattern of the second regions by irradiating the substrate with the beam based on the one-dimensional image data and conveying the substrate based on the information representing lengths.
