    摘要: A xerographic printing machine with at least two rollers disposed so that their axes are arranged parallel to each other. An endless belt, supported by the rollers, has a volume resistance within the range of 10.sup.9 to 10.sup.14 .OMEGA.cm. A photoreceptor is disposed adjacent to the endless belt. An endless belt charging device is disposed opposed to the photoreceptor in such a way that the endless belt is located between the endless belt charging device and the photoreceptor. An electrostatically charged toner supported on the surface of the photoreceptor is transferred to a print media. A guide member is disposed between the photoreceptor and the roller located upstream of the endless belt as viewed in the advancing direction of the endless belt. The guide device guides the advancing print media to bring the print media into contact with the endless belt.

    摘要: An image processor includes an encoder that performs encoding including quantization on an image signal and a controller that controls a quantization parameter for quantization. The controller determines a quantization parameter of a currently target macroblock as an increase or decrease from a reference value, and determines the increase or decrease based on a difference between a target amount of code for a predetermined number of macroblocks fewer than a total number of macroblocks within one frame and a generated amount of code of the predetermined number of macroblocks processed immediately before. The controller can further determine the increase or decrease, based on pixel information of the currently target macroblock such as an activity evaluation value.

    摘要: A beam irradiation apparatus includes a light source which outputs a laser beam, a convergent lens into which the laser beam output from the light source is entered, and a scanning portion which makes the laser beam transmitted through the convergent lens scan on a target region. In the beam irradiation apparatus, the laser light source is arranged such that a pn junction surface of a laser chip is parallel with the vertical direction. Length of the laser beam in the vertical direction on the target region is set by length of a light emitting portion of the laser light source in the vertical direction. Further, a wavefront aberration of the convergent lens with respect to the laser beam is set to be 0.15 λrms or less.

    摘要: An object of the present invention is to provide a detection device which does not cause the false detection by receiving laser light from an oncoming car. The pulse laser light modulated with a modulation pattern set every target position is irradiated at the target position from a laser irradiation portion. DSP (Digital Signal Processor) decides that there is an obstacle at the target position only when the modulation pattern of the pulse laser light emitted from the laser emitting portion matches with the modulation pattern of the pulse laser light received by the laser receiving portion. It is suppressed that the detection device misdetects the conditions of the target position when receiving laser light from an oncoming car or the like because modulation pattern of laser light from own does not match with modulation pattern of laser light from the oncoming car or the like.

    摘要: By providing a nitrogen-doped low carrier concentration layer 13 having both of a donor concentration and an acceptor concentration controlled below 1×1016/cm3 at a p-n junction portion between an n-type GaP layer 12 and a p-type GaP layer 14, the luminance of the GaP light emitting device can be improved by as much as 20 to 30% over the conventional one. Suppressing the donor concentration and the acceptor concentration in the low carrier concentration layer 13 below 1×1016/cm3 inevitably gives a carrier concentration, which is expressed as a difference between both concentrations, lower than 1×1016/cm3 accordingly. The emission efficiency upon injection of electrons or holes can be improved by suppressing the concentration of the donor which serves as non-emissive center below 1×1016/cm3 to thereby extend the carrier lifetime; and by concomitantly suppressing the carrier concentration at a level significantly lower than that in the adjacent layers 12 and 14.

    摘要: An efficient method is proposed for the determination of the concentration of nitrogen in an indirect-transition compound semiconductor such as gallium phosphide added as an isoelectronic trap. The method utilizes the fact that a good correlation of proportionality is held between the nitrogen concentration and the difference .DELTA..alpha.(=.alpha..sub.N -.alpha.) in the absorption coefficient of light of a wavelength identical with the wavelength .lambda..sub.N due to the excitons under constraint in the isoelectronic trap between the semiconductors with (.alpha..sub.N) and without (.alpha.) addition of nitrogen. A working curve is presented between the nitrogen concentration determined by the method of SIMS and the value of .DELTA..alpha..
