  • Patent number: 8287802
    Abstract: There is provided a method and an apparatus for treating return ores using plasma, capable of treating sintered return ores generated in a sintering process in a steel maker or return ores (iron ores) employed in other ironmaking process such as FINEX. The method of treating return ores using plasma includes: providing return ores sorted out by a sorting process; and bonding the return ores by fusing and agglomerating the return ores using plasma. Also, an apparatus for treating return ores using plasma includes a plasma heating device used to fuse and agglomerate sorted return ores. The return ores of a predetermined grain size are fusion-bonded and agglomerated using a flame of a plasma heating device. Particularly, the return ores can be treated in a massive amount to enhance productivity of a fusion-bonding process of the return ores. Furthermore, a great amount of sintered return ores generated in the sintering process can be subjected to a fewer number of re-treatment processes.

  • Patent number: 7995156
    Abstract: A display substrate includes a substrate, signal lines and test lines. The substrate includes a pixel region where pixels are disposed, a buffer region surrounding the pixel region and a grinding region surrounding the buffer region. The signal lines pass through the buffer region from the grinding region to provide the pixels with a driving signal. The test lines are disposed on the grinding region and the buffer region, respectively, so that the test lines intersect the signal lines in a lattice structure. Each of the test lines is electrically connected to the signal lines of a first number calculated by dividing a second number of the signal lines by a third number of the test lines. Thus, the performance of the pixels used for displaying an image may be tested more precisely.

  • Patent number: 7848752
    Abstract: Disclosed is a handoff processing method capable of restarting fast communications. The handoff processing method stores in a handoff buffer Host Control Interface (HCI) data and transmission data upon communications in a state where an Access Point is interlinked with an external device. Further, the method forwards the HCI data and the transmission data buffered in the handoff buffer to a new Access Point (AP) transmitting a message indicating setup completion of a connection if the message indicating setup completion of a connection with the external device is transmitted from the new AP after a handoff occurs as the external device moves. Accordingly, throughputs are not lowered despite handoff occurrences in poor wireless channel environments, so that service quality can be enhanced.

  • Patent number: 7821003
    Abstract: Provided are a thin-film transistor (TFT) substrate and a display device having the same. In the TFT substrate and the display device having the same, first and second drain electrodes of first and second TFTs connected to first and second pixel electrodes, respectively, are vertically bent a plurality of times. The distance between each of the first and second source electrodes and the first or second drain electrode is maintained at a minimum interline gap to increase the distance between a data line and each of the first and second drain electrodes and minimize the length of a region of each of the first and second drain electrodes adjacent to the data line. Consequently, a coupling capacitance between the data line and each of the first and second drain electrodes can be reduced, and each unit pixel region can have a uniform parasite capacitance within a predetermined range. In addition, the luminance deviation of a display device, which performs inversion driving, can be reduced.
