A laser ablation apparatus includes a nozzle, disposed through a housing, wherein the nozzle has: (i) a nozzle housing comprised of a bottom surface; (ii) a first orifice defined by the bottom surface; (iii) a second orifice defined by the bottom surface; (iv) a first passageway defined by the nozzle housing in communication with the first orifice; and (v) a second passageway defined by the nozzle housing in communication with the second orifice, wherein the portion of the second passageway adjacent the second orifice forms an angle .theta..sub.3 with the portion of the first passageway adjacent the first orifice, wherein the angle .theta..sub.3 is effective for directing a first fluid stream through the second orifice at the surface of the enclosed substrate portion to facilitate removal of the coating in the form of coating debris during or subsequent to exposure of the coating of an enclosed substrate portion to high energy radiation. A high energy radiation generating apparatus and a first fluid stream generating apparatus are coupled to the nozzle. A second fluid stream nozzle is disposed in a direction for directing a second fluid stream against the first fluid stream to keep coating debris inside the housing. Exhausting apparatus is coupled to the housing.
摘要:
An electrostatographic imaging member assembly including a hollow electrostatographic imaging drum having a first end and a second end, at least one coating on the drum extending to at least the first end of the drum, the coating having an outer electrostatographic imaging surface and a first drum supporting end cap mounted on the first end of the drum, the first drum supporting end cap including a disk shaped member having an annular skirt encircling an exterior surface of the first end of the cylindrical substrate, the annular skirt having an imaginary axis coextensive with an imaginary axis of the drum. This electrostatographic imaging member assembly may be fabricated by sliding the skirt of the end cap over the end of the drum with or without presoftening of the coating. The electrostatographic imaging member assembly may be utilized in electrostatographic imaging apparatus in which the end caps support electrostatographic imaging apparatus subassembly components.
摘要:
A process for treating an electrostatographic imaging member including providing a hollow cylindrical electrostatographic imaging member having an interior surface, a coated outer surface, a first end and a second end, the interior surface at at least the first end having a coating of adhesive material securing a first end flange to the first end, and propelling solid carbon dioxide pellets against the first end flange and coating of adhesive material with sufficient force to remove the first end flange and coating of adhesive material from the interior surface at at least the first end of the hollow cylindrical electrostatographic imaging member.

摘要:
A hollow cylindrical electrostatographic imaging member supporting end flange including a disk shaped member, a supporting hub extending axially from the disk shaped member and a metal disk coaxially secured to the hub, the disk comprising a plurality of rectangular tabs extending radially from the disk in a direction away from an imaginary axis of the hub for engagement with the hollow cylindrical electrostatographic imaging member upon insertion of the hub and disk shaped member into one end of the hollow cylindrical electrostatographic imaging member. When this end flange is inserted into one end of the hollow cylindrical electrostatographic imaging member, the plurality of rectangular tabs extending radially from the disk engage the inner surface of the hollow cylindrical electrostatographic imaging member.
摘要:
A reusable photoreceptor assembly has a gear assembly removable from a photoreceptor. A square leaf spring or ring is used to secure and remove the gear assembly to and from the photoreceptor, thereby avoiding damage to both the gear assembly and photoreceptor during the removal of the gear assembly. The undamaged gear assembly and photoreceptor may then be reused.
摘要:
A hollow cylinder supporting end flange is disclosed comprising a disk shaped member, a supporting hub extending axially from the disk shaped member and an annular ring supported on the hub, the ring comprising a plurality of sharp protrusions or barbs extending from the ring in a direction away from the hub for engagement with the hollow cylindrical member upon insertion of the annular ring into the hollow cylindrical member. This end flange is utilized in an assembly comprising a hollow cylindrical member having a circular cross section and an inner surface and an end flange comprising a disk shaped member having a circular periphery, a supporting hub extending axially from the disk shaped member into one end of the hollow cylindrical member and an annular ring supported on and secured to the hub, the ring comprising a plurality of sharp protrusions extending from the ring in a direction away from the hub into engagement with inner surface of the hollow cylindrical member to secure the hollow cylindrical member to the end flange.
