  • Publication number: 20090108545
    Abstract: The present invention is directed to a spin chuck for use in a process, such as a cleaning process and an etching process, performed while rotating a substrate. The spin chuck includes a spin head on which a substrate is placed, a driving part configured to rotate the spin head, and a fix bracket installed on the spin head and having a contact surface that is in contact with a flat surface of a flat zone of the substrate at a position corresponding to the flat zone to prevent a vortex caused by the flat zone. Since the fix bracket has the same shape as the flat zone of the substrate, an air current unbalance resulting from the flat zone is suppressed to uniformly inject etchants to a rear surface of the substrate.

  • Patent number: 7377579
    Abstract: A structure for mounting a horizontal hood latch to an automobile includes an upper panel of a front-end module and a bracket over-molded onto the upper panel of the front-end module. A pair of through-openings are provided on opposite side portions of the bracket that allow both surfaces of the bracket to be coated by plastic material and the bracket to be mounted onto the upper panel, as the plastic material is poured thereon.

  • Patent number: 6849690
    Abstract: The present invention relates to a method of preparing rubber-modified styrene copolymer resin with excellent transparency and impact resistance, specifically to a method of preparing transparent resin of rubber-modified styrene copolymer comprising graft-copolymerizing styrene monomer and (meth)acrylate monomer in the presence of block or random styrene-butadiene copolymer which has 30-50% of styrene skeleton content and 20-40 cp of 5% toluene solution viscosity at 25 iÉ. According to the method of the present invention, the transparent resin containing the rubber particles of a double structure comprising onion and core-shell structure can provide transparent resin of rubber-modified styrene copolymer resin with excellent transparency and impact resistance as well as good gloss.

  • Publication number: 20020178362
    Abstract: Disclosed is a method of embedding a hidden digital watermark (also called digital stamp, digital seal, digital signature, etc.) into a produced image which can permanently identify the copyrighter of the produced image to cope with an illegal use or modification thereof by imbedding the hidden digital watermark into the produced image so that the copyrighter can identify his/her authorship when the digital image is first produced by the copyrighter. A color or black-and-white image that only the copyrighter possesses is used as the digital watermark, and the digital watermark is embedded into the produced image in a manner that the human eyes cannot realize the difference between the images before and after imbedding the digital watermark.

  • Patent number: 6221969
    Abstract: Disclosed is a method for producing a rubber-modified styrenic resin. The method includes the steps of (a) producing a rubber solution by dissolving a rubber polymer in a vinyl monomer; (b) producing a rubber composition by continuously supplying the above rubber solution in a first reactor to polymerize the rubber polymer with the vinyl monomer at a reaction temperature of 120°-145° C. to perform phase inversion of the rubber polymer, thereby producing the polymer of conversion ratio of 10-40 wt %, and realized through 50-99% of rubber particles having an average particle diameter of 0.1-0.
