Disclosed is a copolymer for liquid crystal alignment having a photoreactive group, a mesogen group, a thermosetting group, and a crosslinking group, a liquid crystal aligning layer including the copolymer for liquid crystal alignment, and a liquid crystal display including the liquid crystal aligning layer. Since the liquid crystal aligning layer has excellent thermal stability and no residual image, the liquid crystal aligning layer is usefully applied to the liquid crystal display.

Techniques for forming a layer of MetalxSiy without overly depleting the source/drain region of a silicon substrate are disclosed. In one respect, a cobalt layer is formed on a silicon-containing substrate. A metal layer is formed on the cobalt layer. A CoSi layer is formed through heating. Un-reacted cobalt and metal from the cobalt and metal layers are removed. A silicon cap layer is formed on the CoSi layer. A CoSi2 layer is then formed through heating, the CoSi2 layer being formed upward into the silicon cap layer.

Mounting methods of electronic components in which the electronic components are mounted on plural printed circuit boards are disclosed. An exemplary method includes: supplying a printed circuit board on a first conveyor; transferring the printed circuit board to the third conveyor and simultaneously, transferring the printed circuit board transferred to the first conveyor to the second conveyor; mounting the electronic components to about half-portion of the printed circuit board by moving the printed circuit board to one side and simultaneously, mounting the electronic components to about half-portion from the original position of the printed circuit board and transferring the printed circuit board to a fourth conveyor, simultaneously transferring the printed circuit board to the second conveyor to the third conveyor and then discharging the printed circuit boards sequentially.

Provided are a photo reactive polymer that includes a multi-cyclicmulticyclic compound at as its main chain and a method of preparing the same. The photoreactive polymer exhibits excellent thermal stability since it includes a multi-cyclicmulticyclic compound having a high glass transition temperature at as its main chain. In addition, the photoreactive polymer has a relatively large vacancy so that a photoreactive group can move relatively freely in the main chain therein. As a result, a slow photoreaction rate, which is a disadvantage of a conventional polymer material used to form an alignment layer for a liquid crystal display device, can be overcome.

A single-side embossed color steel sheet, and a method for manufacturing the same are disclosed. The steel sheet comprises a steel sheet substrate, a zinc or zinc alloy-plated layer, a non-chromate or chromate pretreated layer, a primary coat paint layer of modified epoxy or modified polyester, a color base paint layer, a printed layer, and a top coat clear paint layer. The color base paint layer comprises a polyester resin as a main resin, a melamine resin as a crosslink resin, a crosslink accelerator, other additives, solvent, etc. The printed layer exhibits a feeling of solidity with various feelings of texture and colors. The top coat clear paint layer serves to protect the printed layer from contaminants. The color steel sheet exhibits a remarkably enhanced feeling of solidity at an irregular surface thereof, and has enhanced contaminant resistance properties and environmental friendliness, thereby satisfying requirements for aesthetic design and functionality of products.

Provided are an apparatus for combining video and a player skin in an embedded system having no graphics card, and a method used by the apparatus. The apparatus includes: an application program; a virtual frame buffer; a graphics processor; and an image processor. The apparatus processes a video player skin image using a virtual frame buffer without a graphics card, and stores the processed video player skin image in a region of a physical main memory, thereby requiring no high-performance CPU, simplifying the hardware structure, and embodying a superior application program without needing a frame buffer and driver compatible with an operating system.

A method for verifying authorization with extensibility in an authentication, authorization, and accounting (AAA) server, and more particularly, a method for verifying authorization in an AAA server capable of uniformly performing an authorization verification function regardless of a variety of authorization verification methods required for a user service provided through a network is provided. The method for verifying authorization with extensibility in an AAA server includes: the AAA server performing user authentication, transmitting the authentication result data to the user, and requesting authorization information for a subscriber service desired to be used, to the user; the user transferring an extensible authorization verification protocol framework having a predetermined format according to an AAA protocol to the AAA server, and requesting verification of the requested authorization; the AAA server verifying whether or not the authorization requested to be verified is set for the user, by referring to the framework; and if the authorization is verified, the AAA server transmitting the authorization verification result to the user, and by allocating a resource related to the authorization, beginning to provide the subscriber service.

Provided are a passive optical network system and a method of transmitting a broadcasting signal in the same system. A central office (CO) generates a broadcasting signal and a downstream optical data signal using a coding method guaranteeing a run-length, multiplexes the downstream optical data signal and the broadcasting signal, and transmits the multiplexed downstream optical data signal and broadcasting signal. A remote node (RN) transmits the multiplexed downstream optical data signal and broadcasting signal received from the CO to one or more optical network units (ONUs). A gain medium, which is located on a transmission line between the CO and the RN, amplifies the broadcasting signal using the downstream optical data signal as a pump light source. Accordingly, a high gain can be obtained by amplifying the broadcasting signal using the gain medium located on the transmission line without a separate pump light source.

Disclosed are a method for automatically controlling volume so that sending volume and receiving volume are equal in accordance with a communication network accessed at a communication terminal, and an apparatus for performing the method. The present invention receives communication information from an accessed base station in a mobile communication terminal and automatically adjusts volume to make sending volume and receiving volume equal in accordance with the received communication information. Accordingly, a user does not need to do anything to control volume.

A method for conserving power in an apparatus is disclosed. The method generally includes the steps of (A) disabling a subset of a plurality of debug operations using a clock signal at a first frequency while in a normal mode, (B) performing a plurality of debug operations using the clock signal at a second frequency while in a debug mode, wherein the first frequency is slower than the second frequency to conserve power, and (C) adjusting the clock signal to one of the first frequency and the second frequency in response to receiving a command generated external to the apparatus to transition to a respective one of the normal mode and the debug mode.
