摘要： An image processing device includes an acquiring unit, a rendering unit, and a mode determination unit. The acquiring unit acquires an input data including a character in a first size. The rendering unit renders an output image based on the input data. The mode determination unit determines whether or not a prescribed mode in which a consumption of printing material is reduced while printing the output image is designated. If the mode determination unit determines that the prescribed mode is designated, the rendering unit renders the output image of the character in a second size smaller than the first size.

摘要： An image processing method determines a number of smoothing times Stime so that the number of times, at which the corrected tone values will be modified, increases as the amount of modification, by which the corrected tone values are required to be modified, increases; and modifies the corrected tone values by dividing the modification amount by the number of smoothing times Stime so that the actual printing characteristics R[i] predicted to be actually obtained approach the ideal characteristics T[i] in steps of the smoothing times Stime. Therefore, the image processing method can prevent an abrupt change in the characteristics of printed color density levels before and after the corrected tone values are modified, even when the modification amount of the corrected tone values is large.
摘要翻译：图像处理方法确定平滑次数Stime的数量，使得校正的色调值将被修改的次数随着需要修改的校正色调值的修改量的增加而增加; 通过将修正量除以平滑次数Stime的数量来修正校正的色调值，使得预测实际获得的实际打印特性R [i]以平滑时间Stime为步长接近理想特性T [i]。因此，即使校正色调值的修正量大，图像处理方法也可以防止修正色调值修正之前和之后的印刷色浓度特性的突然变化。

摘要： A high power factor rectifier circuit, provided with switching sections connected to an AC power supply for converting an AC voltage to a DC voltage, is formed with a bypass circuit provided. The bypass circuit, when the voltage of the AC power supply becomes higher than the voltage across a smoothing capacitor provided on the DC output side, makes a charge current flowing from the AC power supply to the capacitor bypass the switching section by making the switching section out of conduction. Thus, a rectifier circuit is provided which can be safely operated without causing any damage, or with minimized damage, even though an inrush current flows at turning-on the power or at recovery from a power interruption.

摘要： A calibration data creating device includes a reference measured density memory, a dither data memory, a corresponding set density determining unit, a calibration data creating unit, and a calibration data creating unit. The reference measured density memory stores measured densities of reference density patches that are formed by an image-forming unit based on the reference density patch data. The dither data memory stores dither data that has a plurality of dot locations, the dither data having a prescribed threshold at each dot location. The corresponding set density determining unit determines corresponding set densities for the plurality of the reference set densities. The calibration data creating unit creates calibration data indicating a correlation between the set densities and calibrated set densities, the calibrated set density for each set density allowing the dither data to create binarized image data that enables the image-forming unit to form an image whose density is the same as the target density for the each set density.

摘要： An image recording apparatus includes an inputting unit, a half-tone processing unit, a printing unit, a correction-value storing unit, and a dot-position correcting unit. The inputting unit inputs image information on an image. The half-tone processing unit performs, based on the image information, a half-tone process for setting a plurality of dots to be printed on a recording medium. The printing unit prints the plurality of dots on the recording medium. The correction-value storing unit stores a set of correction values for correcting positions of the plurality of dots on the recording medium. The set of correction values includes at least one correction value that is provided for each of the positions of the plurality of dots. The dot-position correcting unit corrects the positions of the plurality of dots based on the set of correction values, thereby obtaining output positions for printing the plurality of dots on the recording medium.

摘要： In a color laser printer, the printing density of images to be formed is corrected based on a correction values stored in a control memory, For each printing operation the printer determines whether the correction values stored in the control memory matches a value stored in a backup memory. If the correction values in the control memory does not match the correction values, in the backup memory, the value of a number of printed pages A serving as the printing performance is incremented by one. If the number of printed pages A is greater than a reference performance number of sheets B pre-stored in memory, then the correction values in the control memory is copied to the backup memory, and the printing operation is executed. If a “Restore correction data” command is inputted, the contents of the backup memory are copied to the control memory.

摘要： A double ended ranging drum shearer is provided with a shearer body and a pair of drums disposed at front and rear end portions of the shearer body to be movable up- and down-wardly. The shearer is further equipped with detectors for respectively detecting the travelling position of the shearer body, detecting the inclination of the shearer body at the travelled position, and detecting the heights of drums at the travelled position. These detectors are operatively connected to a controlling device which is connected to a drum height adjusting device. The controlling device operates and stores the drum heights necessary for keeping constant the working height of a mining face in a pit in accordance with output signals generated from the abovementioned detectors, and the drum height adjusting device is operated in response to an output transmitted from the controlling device representing the thus operated and stored data.
