Abstract: Provided is a molded product manufactured from a thermoplastic resin composition containing a polycarbonate-based polymer, a polysiloxane-polycarbonate copolymer, a polysiloxane-polyester copolymer, and a benzotriazole-based UV stabilizer having a molecular weight equal to or greater than about 1,800.

Abstract: A method of multi-processing an object using a polygon mirror according to an embodiment of the invention includes setting processing parameters for individual layers of an object having a multilayer structure, performing laser processing on exposed layers in a region to be processed of the object according to the processing parameters using a polygon mirror, determining whether or not all of the layers of the object having a multilayer structure are processed, and if it is determined in the determining that not all of the layers are processed, progressing the performing of laser processing. Therefore, efficiency in processing the object can be increased, and cracks that occur in the object during laser processing using a polygon mirror can be minimized.

Abstract: Disclosed herein is a drill for operating implant which allows a user to easily check abrasion of a drill blade with naked eyes. The drill for operating implant includes: a drill body; a drill blade formed on the drill body for perforating an implantation place of the implant when the drill body is rotated; and, an abrasion discrimination part formed at least one of the drill body or the drill blade for allowing a user to discriminate abrasion of the drill blade.
