  • Patent number: 7086175
    Abstract: In a method of manufacturing a liquid crystal panel including a panel assembly, a nozzle mechanism is located at a vicinity of a liquid crystal filling port of the panel assembly with leaving a space between an intake of the nozzle mechanism and the liquid crystal filling port. The nozzle mechanism sucks surrounding gaseous to generate negative pressure and a continuous gaseous flow around the liquid crystal filling port. The negative pressure discharges an excess of liquid crystal filled in the panel assembly while the continuous gaseous flow blows the discharged liquid crystal. The blown liquid crystal is sucked into the intake of the panel assembly. Thus, a gap of the panel assembly is adjusted within a proper range in a short time.

  • Publication number: 20020082714
    Abstract: A processor is efficiently controlled and the electric power required to drive the processor is reduced by switching between a process of driving a plurality of arithmetic units using a series of instructions from an instruction control unit and a process of driving a plurality of arithmetic units using a plurality of series of instructions from different instruction control units according to an object to be processed. When a plurality of instruction control units 10, 11 and 12 drive a plurality of arithmetic units 13, 14 and 15, a synchronous execution process of driving the plurality of arithmetic units 13, 14 and 15 using the series of instructions from the first instruction control unit 10 is switched to/from an independent execution process of driving the arithmetic units 13, 14 and 15 using the series of instructions from the instruction control units 10, 11 and 12, respectively, according to the information contained in the series of instructions.

  • Patent number: 6388671
    Abstract: An information processing apparatus includes a dedicated graphic hardware part dedicated to execution of a specific process function under a pipeline process scheme, and a microprogram execution part executing a process using a microprogram. When three-dimensional graphic information is processed, a process for determining endpoints is executed by the microprogram execution part, and an interpolation process started from an endpoint is executed by the dedicated graphic hardware part for each endpoint process. While the dedicated graphic hardware part is executing the interpolation process, the microprogram execution part is operated in parallel so as to execute the endpoint process for a next endpoint.

  • Patent number: 5822760
    Abstract: A prediction block address is generated from a current block address in accordance with a rule specified by a prediction mode signal. One of two cache memory banks is allocated as a current bank and the other is allocated as a prediction bank. When the current block address is stored in the prediction bank, the allocation of the current and prediction banks is reversed. When the prediction block address is not stored in the prediction bank, a data block specified by the prediction block address is block-read into the prediction bank.
