摘要： A motor driving device includes an amplifying unit, a noise removing unit, an analog-to-digital converter, a calculating unit, and a motor driving unit. The amplifying unit amplifies an analog frequency signal corresponding to a rotation speed of a direct-current brushless motor. The noise removing unit removes noise from the analog frequency signal after amplification. The analog-to-digital converter converts the analog frequency signal from which noise is removed to a digital frequency signal. The calculating unit calculates a current control amount with respect to each phase of the direct-current brushless motor based on the digital frequency signal. The motor driving unit drives the direct-current brushless motor at a specified speed based on the current control amount.

摘要： An image forming device has a full-color image formation mode to form a color image using color photoconductor drums and a monochrome image formation mode to form a monochrome image using a photoconductor drum. In the image forming device, a driving unit drives rotation of an intermediate transfer belt or a transfer transport belt. A control unit changes rotational speeds of the color photoconductors in a transition from the full-color image formation mode to the monochrome image formation mode to make a torque to the driving unit in the full-color image formation mode equal to a torque to the driving unit in the monochrome image formation mode. A separator unit separates the color photoconductors from the intermediate transfer belt or the transfer transport belt after the rotational speeds of the color photoconductors are changed by the control unit.

摘要： A reformer for a fuel cell is structured so that the entirety of a catalytic layer is effectively used, a sufficient shift reaction is made possible, the volume velocity is raised, and the pressure loss is reduced. The reformer includes a container having an inlet for introduction of a vapor of a methanol solution as a raw fuel, an outlet for discharge of a reformed gas and a catalytic layer in the container. It is structured such that the inside of the container is divided into an inlet space communicating with the inlet and an outlet space communicating with the outlet. A passage cross section of the catalytic layer at a side of the outlet space is larger than a passage cross section at a side of the inlet space, preferably by 20% to 250%.

摘要： Disclosed is an image forming device that forms toner images on corresponding photosensitive bodies, and performs primary transfers for transferring the toner images on the corresponding photosensitive bodies onto an intermediate transfer body and performs a secondary transfer for transferring the toner images from the intermediate transfer body onto a recording medium. The image forming device includes a position detection unit that detects a position of the intermediate transfer body; a position control unit that controls movement of the intermediate transfer body; a speed determination unit that determines a speed of the intermediate transfer body; and an image forming control unit. The image forming control unit causes the image forming device to form the toner images, to perform primary transfers or to perform a secondary transfer, when the intermediate transfer body is moving at a constant speed.

摘要： The color offset is reduced with a simple system by relative removal of speed variation components between drums of a tandem color image forming apparatus. Assuming that the speed variation of a magenta photosensitive drum is the largest, the speed variation components of various colors are subtracted from the speed variation component relating to magenta, and the results are added to the respective speed target values. The rotational speed differences of the photosensitive drums of various colors are eliminated by applying the same speed variation component as in the case of magenta to the rotational speed of the photosensitive drums of various colors other than magenta. Phase correction is performed with respect to the phase differences produced by the fact that the distance between drums of various colors is different from the drum peripheral length. Since the phase difference of the photosensitive drums is then zero at the transfer positions of various colors, the effect of speed variation is prevented from appearing in the image as color offset.
摘要翻译：通过相对去除串联彩色图像形成装置的鼓之间的速度变化分量，通过简单的系统来减少颜色偏移。假设品红色感光鼓的速度变化最大，则从与品红相关的速度变化分量中减去各种颜色的速度变化分量，并将结果加到各个速度目标值。通过将与品红色相同的速度变化分量与除了品红色以外的各种颜色的感光鼓的旋转速度相同的方式消除各种感光鼓的旋转速度差。相对于由各种颜色的鼓之间的距离不同于鼓周长的事实而产生的相位差执行相位校正。由于感光鼓的相位差在各种颜色的转印位置处为零，所以防止速度变化的影响在图像中作为颜色偏移出现。
