    摘要: A semiconductor laser device including a laser element stack array emitting a two-dimensional array shaped group of laser beams consisting of rows of laser beams arranged linearly in parallel in a broken line configuration and optical elements arranged in front of the array, receiving rows of laser beams bent and collimated in a direction substantially perpendicular to the orientation of the broken line configuration. Laser beams are emitted from emitters or groups of emitters and are rotated by right angles so as to convert the laser beams to a plurality of rows aligned in parallel in an approximate ladder rung configuration and the distance between center axes of the rows of laser beams is shortened to condense the laser beams by converting them to a group of laser beams emitted from a common object and thereby making all laser beams converge to a single image.

    摘要: A low core loss grain-oriented electrical steel sheet that does not have a significant deterioration in a magnetic flux density and a decrease of a space factor, and which may withstand stress-relieving annealing is provided. Melted and re-solidified layers can be formed on either or both of the surfaces of the grain-oriented electrical steel sheet that extend in a direction that is perpendicular to the rolling direction (e.g., in the direction of the width thereof), at a cyclic interval of not less than approximately 2 mm to less than approximately 5 mm in the rolling direction. The melted and re-solidified layers may be provided on each surface of the grain-oriented electrical steel sheet, and can have an aspect ratio that is a ratio of the depth to the width of the melted and re-solidified layer of not less than approximately 0.20 and a depth of not less than approximately 15 μm. In addition, the melted and re-solidified layers can be formed by using a laser.
