    • In an image forming apparatus, an error detection mark is formed by using an image forming unit on the surface of a carrier along a detection line passing through an exposure position in a carrier moving direction. The error detection mark includes a first mark and a second mark spaced from each other by a fixed distance in the carrier moving direction. The error detection mark is measured by the sensor. A measurement error of the sensor for a registration mark is determined based on the measured values for the first mark and second mark. A registration mark is formed by using the image forming unit on the surface of the carrier on the detection line. The registration mark is measured using the sensor. Offset of an image-forming position is corrected based on the determined measurement error and a measured value for the registration mark.
    • 在图像形成装置中,通过沿着沿载体移动方向穿过曝光位置的检测线在载体的表面上使用图像形成单元形成错误检测标记。 误差检测标记包括在载体移动方向上彼此间隔一定距离的第一标记和第二标记。 误差检测标记由传感器测量。 基于第一标记和第二标记的测量值来确定用于对准标记的传感器的测量误差。 通过在检测线上的载体的表面上使用图像形成单元形成对准标记。 使用传感器测量对位标记。 基于确定的测量误差和对准标记的测量值校正成像位置的偏移。

    • A rolling bearing apparatus capable of restraining the residence of air bubbles in the water-cooling jacket while curbing the running cost and the production cost is provided. A rolling bearing apparatus is configured to include a rolling bearing, and a housing which houses the rolling and in which a water-cooling jacket into which cooling water is introduced. By forming the bottom portion of the water-cooling jacket by an inclined surface in the axial direction, it is possible to preferably rectify the cooling water in the water-cooling jacket and therefore effectively restrain the residence of air bubbles without increasing the amount of water supplied to the water-cooling jacket.
    • 提供一种滚动轴承装置,其能够限制运行成本和生产成本,同时限制水冷套管中的气泡停留。 滚动轴承装置被构造成包括滚动轴承和容纳滚动的壳体,并且其中引入有冷却水的水冷套。 通过沿轴向倾斜地形成水冷套的底部,可以优选对水冷套中的冷却水进行整流,因此有效地抑制气泡的滞留而不增加水的量 供应到水冷套管。
