    摘要： A processing device to form a pattern on a surface of an object to be processed using diffraction of a laser beam emitted from a laser source, the device including: a main body providing a space to process the object using the laser beam emitted from the laser source; a laser transmission unit formed at a first portion of the main body, and configured to diffract the laser beam so that a diffracted laser beam is emitted toward the object; an actuator formed at a second portion of the main body, and connected to the laser transmission unit so as to change an emission pattern of the diffracted laser beam while rotating the laser transmission unit vertically/horizontally or in a set radius; and a controller provided at a third portion of the main body, and connected to the actuator to control an operation of the actuator.

    摘要： A drill device includes a drill tip and a drill body having a rear portion. The drill tip includes at least a first clearance surface and the drill body includes at least a first land having a margin. An edge is disposed between the first clearance surface and the margin. A textured area having a plurality of recesses extends along at least a portion of the margin, in the direction of the rear portion of the drill body, from a position of 200 μm from the edge, from a position on the least first clearance surface, or from a position therebetween.

    摘要： A process of forming a non-optically detectable authentication marking (210,320, 410,535) in a diamond (200,300). Authentication marking (210,320,410,535) is formed adjacent the outer surface of an article formed from a diamond material having intrinsic optical centers. Method includes the step of applying an image of predesigned authentication marking(210,320,410,535) to a region (201,310,530) of a diamond (200,300) at or adjacent the surface of the diamond (200,300) by way of a direct laser writing; wherein the fluorescence background of the diamond material from intrinsic optical center is suppressed by authentication marking(210,320, 410, 535) under fluorescent imaging, such that the non-optically detectable identifiable authentication marking (210,320,410,535) is viewable against the fluorescence background at the region (201,310,530) of the diamond (200,300) where the authentication marking (210,320,410,535) is applied.
