    • Disclosed is a light diffusion resin composition that is prepared by adding a bead type light diffusion resin comprised of PMMA as a light diffuser to a polyester resin according to the present invention. The light diffusion resin composition can be molded into a cover for lightings or sign boards by a processing method such as injection molding, extrusion molding or compression molding, so that the cover has a high haze and high light transmittance, making lamps of the lightings or the sign boards, interior lamps of buildings and contents invisible with a high light transmittance and hence a high level of luminance, provides a low surface resistance to prevent dust-attraction caused by static electricity, and minimizes a deterioration of impact strength, thereby allowing the manufacture of the cover irrespective of size.

    • Disclosed are acrylic polymer beads and an acrylic sol composition containing the acrylic polymer beads that are used for automobile underbody floor, wheel housing, fuel tank, body panel junction and hood, door, or the like for the purpose of water tightness, vibration isolation, and anticorrosion. More specifically, the acrylic polymer beads having a core/shell structure, which are prepared by using a part of the monomer constituting a core layer to form seeds by a seed polymerization, polymerizing the rest of the monomer to form a core layer and then forming a shell layer containing an appropriate amount of a crosslink agent, have a narrow particle size distribution and thereby provide, when used in addition to a plasticizer and a filler in the preparation of an acrylic sol composition for automobile, high storage stability of the acrylic sol and excellent properties of the coating formed by gelation of the acrylic sol.

    • Laser processing equipment is provided. The laser beam processing equipment includes a laser resonator, an optical system, a chamber, a reflector, and a laser beam aligning unit. The laser resonator resonates a laser beam. The optical system converts the laser beam resonated by the laser resonator to have an energy density of a beam profile with a predetermined beam width. The laser beam converted by the optical system is radiated onto a processing object disposed in the chamber. The reflector is disposed between the laser resonator and the chamber to reflect the laser beam. The laser beam aligning unit aligns the laser beam radiated into the chamber. The laser beam aligning unit includes an aligning member installed between the reflector and the processing object and disposed in a travel path of the laser beam. The aligning member defines a through-hole that is greater in area than a cross-section of the laser beam to enable the laser beam to pass therethrough. The driver drives the reflector to control the travel path of the laser beam reflected by the reflector. The controller controls the driver to control a distance between a center of the laser beam and a center of the through-hole, based on the laser beam detected as passing through the through-hole of the aligning member.
    • 提供激光加工设备。 激光束处理设备包括激光谐振器,光学系统,腔室,反射器和激光束对准单元。 激光谐振器谐振激光束。 光学系统将由激光谐振器谐振的激光束转换成具有预定光束宽度的光束轮廓的能量密度。 由光学系统转换的激光束照射到设置在腔室中的处理物体上。 反射器设置在激光谐振器和腔室之间以反射激光束。 激光束对准单元对准辐射到腔室中的激光束。 激光束对准单元包括对准构件,该对准构件安装在反射器和处理对象之间并且设置在激光束的行进路径中。 对准构件限定面积比激光束的横截面大的通孔以使激光束能够穿过其中。 驱动器驱动反射器以控制由反射器反射的激光束的行进路径。 控制器控制驱动器基于检测为穿过对准构件的通孔的激光束来控制激光束的中心与通孔的中心之间的距离。
