Abstract: A computer-implemented simulation method for use in molding process by a computer processor includes specifying a simulating domain having a mold cavity configured to connect a tube of a molding machine, creating a mesh by dividing at least part of the simulating domain, generating at least one flow parameter of a molding material in the tube, specifying boundary conditions of the mesh by taking into consideration the at least one flow parameter of the molding material, and simulating a molding process of the molding material that is injected into the mold cavity by using the boundary conditions to generate a plurality of molding conditions.

Abstract: A cycloolefin in copolymeric (COC) optical communication device. The COC optical communication device includes a core section of functional metallocene cycloolefin copolymer (f-mCOC) having a refractive index n1 for light transmission, and a cladding layer of metallocene cycloolefin copolymer (mCOC), having a refractive index n2 smaller than n1, surrounding the core section and forming a waveguide structure together with the core section. Due to the fact that the various components of the optical communication device are comprised of essentially the same materials, signal transmission loss between heterogeneous interfaces is prevented, and provides excellent optical properties and superior processability.

Abstract: Disclosed is a filmless sticker for transfer-printing an ink in a pattern and/or characters thereon to a receiver. Said filmless sticker is composed of a releasing paper having a binder on one surface thereof, a soluble film disposed on said binder, and a layer of ink in a pattern and/or characters printed onto said soluble film. The process for preparing said filmless sticker is also disclosed.
