Abstract: <P>PROBLEM TO BE SOLVED: To provide a silicon single crystal which has a diameter of at least 200 mm over a length of at least 200 mm and is free of dislocations.  <P>SOLUTION: The atmosphere of inert gas and nitrogen in a receptacle has a pressure of 1.5-2.2 bar, and the atmosphere is continuously exchanged. In this case, at least twice of the volume of the receptacle is exchanged per hour. A flat coil with an external diameter of at least 220 mm is used in order to melt a stock ingot. The single crystal is pulled at a rate in a range of 1.4-2.2 mm/min and is periodically rotated through a sequence of rotation angles. The direction of rotation is changed after each rotation by a rotation angle belonging to the sequence. For example, the single crystal is first of all rotated clockwise through the angle α1 at a rotational speed N1. Then a change in the direction of rotation is performed and a rotation in the counterclockwise direction through the angle α2 is performed at a rotational speed N2, followed by periodically recurring rotations through α1 and α2. A high quality single crystal stable in the shape can be obtained by optimally performing selection of rotation angle.  <P>COPYRIGHT: (C)2010,JPO&INPIT

IPC: G03G15/02
Filed: 2009-06-19
Abstract: <P>PROBLEM TO BE SOLVED: To solve such a problem that where a cleaning brush is rotated following a charging roller, the peripheral speed of the cleaning brush tends to be unstable due to permanent deformation of the cleaning brush although there is a benefit in cost, while where the cleaning brush is rotated by gear connection with the charging roller, the peripheral speed of the cleaning brush tends to be stable although a cost increases.  <P>SOLUTION: In an image forming portion using the cleaning brush that is long, the cleaning brush and the charging roller are driven and coupled by a gear train. In an image forming portion using the cleaning brush that brush length is comparatively shorter, the cleaning brush is rotated by following the charging roller. This ensures a stable charging process for a long time in the image forming portion using the cleaning brush that brush length is longer, whereas a cost can be reduced in the image forming portion using the cleaning brush that brush length is comparatively shorter. That is, the apparatus achieves the cost reduction as well as a long lifetime.  <P>COPYRIGHT: (C)2010,JPO&INPIT
