  • Publication number: 20140197329
    Abstract: To avoid a glow discharge during the use of a conventional gas ionization chamber, there is no alternative but to increase a gas pressure. Therefore, while a conventional gas ionization chamber is used, an ion current cannot be increased by raising a gas introduction pressure. An object of the present invention is to increase the ion current by raising the gas pressure and prevent an ion beam from being scattered by an ionization gas. The gas is supplied from a structure maintained at a ground potential to prevent the application of a high voltage to the vicinity of an ionization gas introduction port at which the gas pressure is relatively high. Further, the ionization gas existing in a region through which the ion beam passes is preferentially reduced by performing differential evacuation from a lens opening in a lens electrode that forms an acceleration/focusing lens.

  • Patent number: 8610960
    Abstract: It is difficult to appropriately estimate the colorimetric values of an arbitrary patch at a desired temperature with respect to a medium containing a fluorescent whitening agent in consideration of the influence of the fluorescent whitening agent. A target temperature and media type are designated (S601, S602), patches of a plurality of colors are formed on a set medium, and a temperature immediately after fixing (second temperature), patch colorimetric values, and medium white colorimetric values are acquired (S606, S607). Medium white calorimetric values at the target temperature are generated based on the acquired medium white calorimetric values and medium white colorimetric values at a first temperature, which are acquired in advance (S608). Patch calorimetric values at the target temperature are estimated based on the generated medium white colorimetric values and patch colorimetric values.

  • Patent number: 8587831
    Abstract: It is difficult to appropriate estimate the colorimetric values of an arbitrary patch at a desired temperature with respect to an arbitrary medium in consideration of the influence of a fluorescent whitening agent contained in the medium. Target patch colorimetric values obtained when patches of a plurality of colors formed on a medium using color samples are measured at a target temperature designated in step S101. This estimation is implemented when both media-dependent variation correction processing (S102) that estimates patch colorimetric values based on the temperature characteristics of the medium, and toner-dependent variation correction processing (S103) that estimates patch colorimetric values based on the temperature characteristics of the color samples are executed. By correcting image data whose image is to be formed based on the target patch colorimetric values (S104), an arbitrary color patch on an arbitrary medium can be coped with.

  • Patent number: 8514451
    Abstract: The colorimetric values of a plurality of reference color patches formed on a specific medium are measured at a plurality of temperatures, and a temperature characteristic LUT in a colorimetric value temperature correction unit is created based on the colorimetric values. Upon creating a calibration LUT, a patch based on arbitrary device values is formed on the medium, and a patch temperature and colorimetric values are acquired immediately after fixing of that patch. A correction target temperature as a temperature upon observation of the medium is, for example, fixed, the colorimetric values are corrected by interpolation processing based on the temperature characteristic LUT to obtain colorimetric values, and a calibration LUT is created based on the colorimetric values.

  • Publication number: 20130177835
    Abstract: By using a composite material that is produced from an acid salt of an oxo acid compound and an azole compound, a proton conductor with good proton conductivity properties under medium temperature, non-humidified conditions may be achieved. The composite material may be produced by mechanical milling of the acid salt of the oxo acid compound and the azole compound using a planetary ball mill The structure of the composite material obtained by the mixing processing may be different from that of a mixture of the acid salt of the oxo acid compound and the azole compound. Therefore, it may be possible to produce the proton conductor that has good proton conductivity properties under medium temperature, non-humidified conditions with a simple method of mechanical mixing.
