摘要： An optical disk 100 is provided with a hub 3 at the central portion of a substratel. A relationship Y/X≧0.015, preferably Y/X≧0.05 is satisfied where X is the projected area of the substrate 1 and Y is a contact area between the hub 3 and the substrate 1. As result, no slippage occurs between the hub 3 and the substrate 1 even when they are rotated at high speed than conventional. With this higher rotational speed, the data transfer rate is improved, and irregular rotation and the camming are suppressed, thereby reducing tracking errors and write/read errors.
摘要翻译：光盘100在基底的中心部分设置有轮毂3。满足关系Y / X> = 0.015，优选为Y / X> = 0.05，其中X是基板1的投影面积，Y是毂3和基板1之间的接触面积。结果，即使在轮毂3和基板1之间高速旋转时也不会发生滑动。利用这种较高的转速，数据传送速率得到改善，并且不规则旋转和凸轮被抑制，从而减少跟踪误差和写/读错误。

摘要： A corrugating roller unit is moved smoothly between a first reference plane and a second reference plane at different heights by a roll-out apparatus having a set of moving support device. A first moving support device supports the corrugating roller unit when the corrugating roller unit is in contact with the first reference plane. A second moving support device supports the corrugating roller unit when the corrugating roller unit is in contact with the second reference plane. A positioning device keeps the second moving support device in contact with the second reference plane when the second moving support device is providing the support for the corrugating roller unit. When the second moving support device moves the second reference plane to the first reference plane, the positioning device prevents the second moving support device from restricting movement of the corrugating roller unit. The resulting corrugating roller unit is inexpensive and does not require floor construction work at a corrugated cardboard production plant.
摘要翻译：波纹辊单元通过具有一组移动支撑装置的滚出装置在不同高度的第一参考平面和第二参考平面之间平稳地移动。当波纹辊单元与第一参考平面接触时，第一移动支撑装置支撑波纹辊单元。当波纹辊单元与第二参考平面接触时，第二移动支撑装置支撑波纹辊单元。当第二移动支撑装置为波纹辊单元提供支撑时，定位装置保持第二移动支撑装置与第二参考平面接触。当第二移动支撑装置将第二参考平面移动到第一参考平面时，定位装置防止第二移动支撑装置限制波纹辊单元的移动。所得到的波纹辊单元便宜，并且不需要瓦楞纸板生产设备的地板施工。

摘要： An encoder includes a code plate, a detector, a transformer, and first and second calculators. The code plate is formed with an absolute pattern including a plurality of bit patterns, each bit pattern formed by a predetermined number of bits and representing one absolute position. The detector moves relatively with respect to the code plate, has a plurality of detecting elements arranged to be opposed to the predetermined number of bits, and reads the bit pattern from the absolute pattern to output a bit pattern signal representing the bit pattern. The transformer can transform only specific bit pattern signals corresponding to specific bit patterns out of a plurality of the bit pattern signals corresponding to the plurality of bit patterns, into the absolute positions. The first calculator calculates a relative, positional relation between the bit pattern corresponding to the bit pattern signal, read from the detector, and the specific bit pattern. The second calculator calculates information indicating a position of the code plate relative to the detector, based on the absolute position obtained by the transformer and the relative, positional relation obtained by the first calculator.
