Abstract: A high-heat-retention ladle for carrying molten aluminum includes a ladle body defining therein a storage space, which contains molten aluminum therein, the ladle body including a molten metal inlet and a molten metal outlet, which allow the storage space to communicate with outside, a cover opening and closing the inlet of the ladle body, and a stopper opening and closing the outlet of the ladle body. Each of the ladle body and the cover has an outer shell, which defines a contour thereof, and a multi-layer insulation structure inside the outer shell. The multi-layer insulation structure includes two or more refractory layers. The molten aluminum contained inside the storage space has a temperature drop rate of 5° C./min or less. It is possible to carry the molten aluminum for a long time in a heat-insulated state and cast a product by directly pouring the molten aluminum into a mold.

Abstract: An integrated management system for molten aluminum includes a melting process management system, which melts aluminum raw material, taps molten aluminum, and extracts information related to the molten aluminum; a recording medium attached to a high-heat-retention ladle, which is for carrying the molten aluminum, wherein the extracted information is recorded into the recording medium; a portable terminal, which reads the information from the recording medium; and a casting process management system, which manages delivery confirmation and inspection by receiving the information from the transported high-heat-retention ladle via the portable terminal and performs a casting process based on the information. The integrated management system and method ensures improved and efficient process management based on correct molten aluminum information, thereby reducing management costs and time.

Abstract: Sync positions are detected from a video signal. The detected sync positions are processed (e.g., averaged) to generate modified sync positions. The detected sync positions and the modified sync positions are selectively used to sample and synchronize a color signal derived from the video signal. For example, the detected sync positions and the modified sync positions may be selectively used to sample and synchronize the color signal responsive to differences between the modified sync positions. The invention may be embodied as apparatus and/or methods.

Abstract: An apparatus and method for measuring frame loss in multicast service traffic are provided. The method of measuring frame loss includes: counting the number of data frames of a predetermined multicast service flowing into an object network of frame loss measurement; counting the number of data frames of the predetermined multicast service flowing out of the network; and measuring frame loss by comparing the counted number of incoming frames and the counted number of outgoing frames. According to the method and apparatus, in a multicast service environment which is dynamically changing, frame loss of a predetermined multicast service can be conveniently and easily measured.

Abstract: A method for transferring data frame end-to-end in a local area network is provided. In the method, a virtual synch frame shaper is loaded on a frame transmission layer structure provided in end stations in transmitting and receiving sides, which transmits data frame passing through a plurality of Ethernet switches in the LAN. Then, slot counters, which are counted through the virtual synch frame shaper, are exchanged between the end stations, and the slot counters are synchronized. Afterward, the transmit time slot is allocated based on the synchronized slot counters for transmitting data frames between the end stations. Finally, data frames are transmitted based on the synchronized slot counters and the allocated transmit time slot.

Abstract: In the scanning conversion apparatus, a first converter converts input interlaced scan data into progressive scan data, and a second converter converting the progressive scan data output from the first converter to interlaced scan data.

Abstract: Disclosed is a liquid crystal display (LCD) controller with improved dithering and frame rate control to reduce the physical (hardware) cost and power consumption, and a method thereof. The LCD controller utilizes a mechanism of minimizing a size of a dithering pattern register which stores plural gray levels. A duty cycle value for the respective gray levels is determined by using the same bit number as denominator values of the plural gray levels. The LCD controller includes a dithering pattern register section for storing the plural gray levels, modular register counters for performing counting operation to determine a binary value of most significant bit of the respective gray levels, multiplexers for generating data patterns for the respective gray levels in accordance with an output of the respective modular register counters; and a selection means for selecting and generating a corresponding bit of a data pattern corresponding to pixel data provided on a LCD panel.

Abstract: The present invention relates to a method for preparing the crystal of human derived TRAIL protein and TRAIL receptor protein sDR5 complex and the crystal of TRAIL-sDR5 complex prepared by the method. The present invention also TRAIL relates to a three-dimensional structure of TRAIL protein in the form of complex with TRAIL receptor sDR5 as well as TRAIL protein itself, and specific residues existed in the contact central region of AA″ loop. The three-dimensional structure of TRAIL-sDR5 complex and the specific residues in the AA″ loop of the present invention can be effectively used for not only the development of TRAIL protein having the better cytotoxic activity and having the improved receptor biding affinity, which specifically kills viral infected cells or cancer cells but also molecular strategy for regulating the binding specificity between TNF and TNFR family.
