  • Patent number: 7243183
    Abstract: A switch system including a plurality of input ports and a plurality of output ports for transferring data from one of the input ports to one of the output ports, and a plurality of memory devices is disclosed. The memory devices include a first memory bank configured for data being written to the first memory bank while data is read from the first memory bank at a timeslot and a second memory bank, which is smaller than the first memory bank and configured for writing the data read from the first memory bank to the second memory bank and reading data from the second memory bank. The system further includes an address comparer configured to compare a write address of the first memory bank with a read address of the first memory bank and select data for output from the first memory bank if the write address is smaller than the read address and select data from the second memory bank if the read address is equal to or smaller than the write address.

  • Patent number: 6867840
    Abstract: A method of manufacturing a liquid crystal display panel, comprising the steps of: forming a plurality of pixels on a first substrate; forming a plurality of micro cell structures on the first substrate, wherein each micro cell structure surrounds at least one pixel; forming a first alignment layer on the first substrate; providing the micro cell structures with a liquid crystal by utilizing Ink Jet Printing technology; and combining the first substrate with a second substrate by forming a sealing member therebetween.

  • Patent number: 4212452
    Abstract: A method and apparatus for the direct reduction of iron ore are disclosed. A mixture of iron ore, solid carbonaceous fuel and, if sulfur is present, calcined limestone or dolomite, are used. The carbonaceous material can be cellulosic material (wood waste, paper, particularly municipal trash, garbage, etc.), charcoal, or coal (preferably sub-bituminous coal or lignite). The above feed is continuously charged into a gasification and initial reduction zone of a shaft furnace which is partitioned partially from the remainder of the furnace. Oxygen and hot steam are introduced into the upper portion of the said zone. Partial combustion or pyrolysis of the fuel and reaction with steam take place, producing reducing gas which initiates reduction of the iron ore. Ore and gas flow downwardly through conduits into the final reduction zone. Meanwhile, hydrogen-enriched reducing gas is introduced in the middle of the final reduction zone.
