In the present invention, a length of elongated single crystal ingot is mounted adjacent its ends and is ground while being rotated to provide a cylindrical shape. While still mounted, the crystal is rotated into a position to be x-rayed for the grinding of a flat thereon with the crystal in a non-rotated state.

A method of making an ingot length of a single semiconductive crystal having substantially uniform resistivity throughout most of the length of the ingot is disclosed. An inert helium atmosphere is placed about a mass of silicon material and then the silicon mass is melted. A seed of silicon is inserted into the melt and withdrawn at a rate which provides a substantially uniform ingot diameter. As the seed is withdrawn from the melt, the pressure in the system is slowly reduced to vaporize the i...

Systems and methods of remanufacturing an imaging cartridge including the replacement an organic photo conductor (OPC) drum in the imaging cartridge having end caps which are fixedly secured to the waste bin or other portion of the toner cartridge. In one aspect, the method involves removing the existing OPC drum without detaching the end caps and installing a replacement OPC drum without disturbing the end caps.
