  • Publication number: 20080311428
    Abstract: In an Mn-containing perovskite oxide which is a conventional phase-change substance (A1?xBx)MnO3, when the mixing amount x is increased, the transition temperature (Tc) is shifted to higher temperature side, but the slope of a change in the emittance become gentle and ?? (? at higher temperature?? at lower temperature) also become small. In the present invention, the compositional formula of the phase-change substance is the Mn-containing perovskite oxide represented by (A1?xBx)Mn1+yO3 with 0<y in which the Mn ratio is changed from stoichiometric composition, thereby shifting the transition temperature (Tc) to a higher temperature with the emittance characteristic thereof comparable to that of the phase-change substance having the composition which is not changed from stoichiometric composition.

  • Patent number: 7445204
    Abstract: When a to-be-transported printing medium is fed in association with an operation for transporting the printing medium to a predetermined printing start position, a control is provided so as to eliminate an emergency stop of the feeding operation that tends to be caused due to an increase in the printing speed, thereby realizing a high-speed printing. To provide this, prior to a determination of the printing start position, the feeding by a feeding roller of the printing medium is started. Thereafter, when the printing start position is fixed within a predetermined period after the detection of a front end of the printing medium, whether or not to stop the feeding roller is determined at this timing. The predetermined period is a period during which the printing medium can be stopped at a predetermined stop position at which the printing medium is not yet caught by a transportation roller.

  • Publication number: 20080031337
    Abstract: A quantization step determination part inputs an evaluation value (ACT_MB) indicating the dispersion in a macroblock and its average value (ACT_PIC). A subtracter obtains the difference between these values, and a multiplier multiplies the difference by raq (<1) to obtain a weighting value. Next, an adder adds the weighting value to an average quantization step value of source data, and finally a multiplier multiplies the sum by a step value adjustment factor ? (>1) to obtain a converted quantization step value (Qstep_AVC). This optimizes a bit allocation in accordance with an Activity value of the macroblock, to thereby improve the quality of image.
