Title: Developing device
Inventor: NOMURA YOSHIYA
IPC: G03G15/08
Filed: 1991-04-26
Abstract: PURPOSE:To offer a low cost developing device in which a developer carrier is rotated without causing uneven rotation. CONSTITUTION:The device is provided with a drive force transmitting means 30 for rotating the developer carrier 21, with which an image carrier 1 press- contacts and which follows the carrier 1 and is rotated by frictional force accompanied with the rotation of the image carrier 1. Since the carrier 21 is rotated by following the carrier 1 through the frictional force, it is rotated more smoothly than it is rotated through a gear, etc., and the uneven rotation is not caused in its rotation. Then, the means 30 has only to transmit the frictional force to the carrier 21, so that its constitution is simple in comparison with the gear, etc., and the cost of the device is reduced as much as by the simplification of the constitution.

Filed: 1993-04-28
Abstract: PURPOSE:To facilitate management and operation of the quartz glass jig for semiconductor industry by forming opaque parts on the quartz glass jig, disposing black paper on the surface on the side opposite to the opaque parts at the time of reading and reading the opaque parts by a bar code reader. CONSTITUTION:The opaque parts 2 are formed on the quartz glass jig for semiconductor industry and the black paper is disposed on the opposite surface. The bar codes 1 is formed of the black parts viewed through the transparent parts on the rear side as black lines and the opaque parts as white lines, thereby the quartz glass jig is read by a bar code reader. The opaque processing parts 2 of >=10mm width are formed at both ends of the bar codes 1 at the time of forming the opaque parts 2. Reading with a bar code reader is made possible by formation of these opaque processing parts 2. Namely, the laser beam emitted from the bar code reader causes an irregular reflection in the opaque parts 2 and the bars of the formed opaque parts 2 are read as white signals. The glass parts between the other opaque parts 2 are transparent and allow the good transmission of the laser beam and are, therefore, read as black signals.
