摘要： PURPOSE: To prevent breaking of thread as a result of the thread being forcibly rolled in a roller, by a method wherein, through mounting of an air exhauster, having a rotary blade rotated together with a roller, the thread on the outer periphery of the roller is floated by dint of an air flow.
CONSTITUTION: A thread 36 is fed to a knitting machine as it is wound around the outer periphery of a roller 4. A rotary blade 12 is rotated together with the roller 4, and air in the lower part of a casing 7 is rotated at a high speed to exhaust the air through an exhaust port 19. Since a pressure at a central part in the lower part of the casing 7 is reduced, air at the outside from through an air inlet 5 into an outer cylinder 3, and is sucked through a bleeder 9 in a suction port 18. Since the thread 36 is pulled by the knitter during operation of the knitter and the thread 36 is forced into contact with the outer periphery of the roller 4, the thread 36 is prevented from floating from the roller 4 thanks to an air flow. When running of the thread 36 is stopped resulting from a stop of operation, the thread 36 on the outer side of the roller 4 is also stopped. Besides, since a motor 22 is designed to be prevented from a stop, the roller 4 continues rotation together with the rotary blade 12.

摘要翻译：目的：为了防止由于在辊中被强制卷绕而导致螺纹断裂，通过这样一种方法，其中通过安装具有与辊一起旋转的旋转刀片的排气装置，螺纹在外周上辊子被气流漂浮。构成：当纱线卷绕在辊子4的外周时，纱线36被供给到针织机。旋转刀片12与辊子4一起旋转，壳体7的下部的空气以高速地通过排气口19排出空气。由于壳体7的下部的中央部的压力减小，外部的空气从空气入口5流入外筒3，并被吸入在吸入口18中设置有泄放部9.由于纱线36在针织机的操作过程中由编织机牵引，并且丝线36被迫与辊子4的外周接触，因此防止纱线36从辊子 4感谢气流。当由于停止操作而停止螺纹36的运转时，辊4外侧的螺纹36也停止。此外，由于马达22被设计成防止停止，所以辊4与旋转叶片12一起继续旋转。

摘要： A recorded stream generator generates a data block stream in synchronism with the phase of a recording clock, from the input data. The recorded stream generator further generates, for each predetermined data unit constituting the data block stream, a data phase reference pulse indicative of the phase of the data unit. An inserting section inserts a VFO signal into a predetermined amount (32 sectors) of the data block stream, the VFO signal having a length of time corresponding to a difference in phase between an wobble address phase signal and a data phase reference pulse. The inserting section thus provides a data stream DST consisting of the VFO signals and the data block streams. An LD uses light beams to record the data stream on an optical disk.
