Patent number: 9170542Abstract: An image forming apparatus capable of accurately forming an image in a predetermined position on a sheet. An image forming unit forms a toner image on a drum. The toner image is transferred onto a belt. A motor drives the belt to convey the toner image to a transfer position where the toner image is transferred onto a sheet. An image position-detecting section detects that a patch image indicating the position of the toner image on the belt has reached a detection position upstream of the transfer position in an image conveying direction. A sheet position-detecting section detects that the leading edge of the sheet has reached a detection position upstream of the transfer position in a sheet conveying direction. An image speed-setting section controls the conveying speed of the belt based on timings of detection by the respective image position-detecting and sheet position-detecting sections.Type: GrantFiled: September 26, 2013Date of Patent: October 27, 2015Assignee: CANON KABUSHIKI KAISHAInventors: Takashi Hiratsuka, Yasumi Yoshida, Takaaki Aoyagi, Takeshi Aoyama

Patent number: 9126838Abstract: The method comprises at least three steps of a hydrogenation step (101) and/or a chlorination step (102), an impurity conversion step (103), and a purification step (104). In the impurity conversion step (103), an aldehyde compound represented by the general formula Ar—R—CHO (Ar; denotes a substituted or unsubstituted aryl group, R; denotes an organic group having two or more carbon atoms) is added to convert donor impurities and acceptor impurities contained in a chlorosilane distillate to a high-boiling substance. The chlorosilane distillate after the donor impurities and acceptor impurities have been converted to a high-boiling substance is sent to the purification step (104). In the purification step (104), high purity chlorosilanes from which the donor impurities and acceptor impurities have been thoroughly removed are obtained by using a distillation column or the like, where the high purity chlorosilanes are recovered outside the system from the top of the column.Type: GrantFiled: September 2, 2011Date of Patent: September 8, 2015Assignee: Shin-Etsu Chemical Co., Ltd.Inventors: Masayuki Hasegawa, Yoichi Tonomura, Tohru Kubota, Takeshi Aoyama, Shuji Tanaka
