  • Publication number: 20130258378
    Abstract: A first RIP processing unit reads cache data from a first cache unit. The first RIP processing unit transmits first RIP-processed variable part data to a printer. Since an identifier read by the first RIP processing unit is not a transmitted identifier, the first RIP processing unit transmits RIP-processed reuse part data to the printer. A second RIP processing unit reads cache data from a second cache unit. The second RIP processing unit transmits second RIP-processed variable part data to the printer. Since an identifier read by the second RIP processing unit is a transmitted identifier, the second RIP processing unit does not transmit the RIP-processed reuse part data to the printer.

  • Publication number: 20130258021
    Abstract: Each unit of an inkjet printing station includes chains arranged along a transportation path of a web paper. A holding mechanism is fixedly arranged on the chain. The holding mechanism holds both ends of a paper passing bar to which the web paper is attached. Driving the chain with a handle causes the holding mechanism to move. The paper passing bar is delivered between the units adjoining each other. Therefore, the paper passing bar is movable from one end to the other end of the inkjet printing station formed by the units. Moreover, when specifications are changed for changing combination of the units, the combination can be made optionally.

  • Publication number: 20130250341
    Abstract: Compressed data transmitted to a print control apparatus includes break data having information on a compressed size and a decompressed size for each page. When the compressed data is transferred to a decompressing unit, the break data is converted to NOP data. Information on the decompressed size included in each break data is provided to a checking unit. During a period in which a decompression process is performed, a decompression flag is turned on. The checking unit obtains the actual decompressed size by counting a period in which the decompression flag is turned on, to check whether the decompression process has been normally performed. During a period in which the decompressing unit and the checking unit perform processes for a certain page, a reading unit reads compressed data for the next page.

  • Publication number: 20130248504
    Abstract: The temperature of a semiconductor wafer is raised by light irradiation heating performed by halogen lamps. An infrared ray emitted from the semiconductor wafer whose temperature has been raised transmits through an infrared-transparent window made of silicon, and then is detected by an infrared camera. The infrared camera two-dimensionally detects the temperature of an entire surface of the semiconductor wafer. Based on a result of the detection obtained by the infrared camera, a temperature drop region having a relatively low temperature among the region of the semiconductor wafer is irradiated with laser light emitted from a laser light emission part. Accordingly, without rotating the semiconductor wafer, a temperature distribution can be made uniform with a high accuracy throughout the entire surface of the semiconductor wafer.

  • Publication number: 20130242006
    Abstract: Ink in an ink tank is fed through a dissolved gas control filter to a printer head. A gas pressure changing mechanism reduces pressure in a gas pressure control tank. In response, the dissolved gas control filter removes gas dissolved in the ink. The gas pressure control tank is placed under pressure corresponding to a sum of the pressure reduced by the gas pressure changing mechanism and the pressure of the gas having been removed from the liquid. A gas pressure measuring part measures the sum of these pressures as pressure in the gas pressure control tank. Then, a controller determines when time of exchange of the dissolved gas control filter has come based on the magnitude of a gradient of gas pressure variation in the gas pressure control tank.

    Abstract: In an inkjet printer, a pattern for density correction that indicates a constant density image is printed on printing paper with a head having a plurality of outlet rows, and pattern image data that indicates the pattern is acquired. A target outlet that ejects ink toward a linear region having a missing part in the pattern is detected, and a reference outlet that is included in the same outlet row as the target outlet and located close to the target outlet is specified. A density correction value of the target outlet among density correction values that are acquired based on a density profile of the pattern is replaced with a representative value of a density correction value of the reference outlet. Through this, even if an ink ejection failure occurs in any of the outlets, appropriate density correction values can be obtained for a plurality of outlets.

  • Patent number: 8513574
    Abstract: Flash lamps connected to short-pulse circuits and flash lamps connected to long-pulse circuits are alternately arranged in a line. The duration of light emission from the flash lamps connected to the long-pulse circuits is longer than the duration of light emission from the flash lamps connected to the short-pulse circuits. A superimposing of a flash of light with a high peak intensity from the flash lamps that emit light for a short time and a flash of light with a gentle peak from the flash lamps that emit light for a long time can increase the temperature of even a deep portion of a substrate to an activation temperature or more without heating a shallow portion near the substrate surface more than necessary. This achieves the activation of deep junctions without causing substrate warpage or cracking.

  • Publication number: 20130206747
    Abstract: The front surface of a semiconductor wafer with a back surface supported by lift pins is irradiated with a flash of light from flash lamps, so that the semiconductor wafer is heated. A transparent restriction ring made of quartz is into abutment with or close to a peripheral portion of the front surface of the semiconductor wafer. In this state, the flash irradiation is performed. If the temperature of the front surface of the semiconductor wafer rises rapidly when the flash irradiation is performed, the restriction ring restrains the semiconductor wafer from jumping up from the lift pins. This prevents wafer cracking resulting from the jumping of the semiconductor wafer when the flash irradiation is performed.
