Patent CA-2325264-A1 (CA)
Inventor: CUCIUREAN-ZAPAN CLARA
IPC: H04N1/58
Filed: 2000-11-08
Abstract: Selective edge softening and selective edge dithering is introduced into an image representation to improve local control where halo problems are expected. Selective areas of dilation are isolated and separately dithered or halftoned, the result of which is then swapped back into or substituted for the stored original image. In this manner misregistration and color plane-to-plane interactions can be compensated for in plural image forming station architecture systems. The same technique is also valuable in monochrome systems as an aid to overcoming edge displacement and slow toner problems when the selective edge softening is selectively applied to edges which are in particular perpendicular to the fast scan direction.

IPC: B29C45/27
Filed: 2001-07-03
Abstract: Injection molding apparatus wherein a heated nozzle extends into an opening in a cooled mold. The nozzle has a locating and sealing ring made of a deformable material. After installation the locating and sealing ring contacts an inwardly tapered suraface of the mold or an insert seated in the mold extending around the opening.  When the nozzle is heated to the operating temperature, thermal expansion drives the locating and sealing ring forwardly into greater contact against the inwardly tapered surface. In one embodiment, the locating and sealing ring is near the front of the nozzle, and the nozzle also has a rear the front of the nozzle, and the nozzle also has a rear locating flange. During insertion of the nozzle into place in the opening and thermal expansion of the nozzle, the rear locating flange first comes into contact with an inwardly tapered shoulder extending around the opening which prealigns the nozzle. Then before the front locating and sealing ring comes into contact with the inwardly tapered surface and is partially deformed thereby which very accurately align the tip of the nozzle with the gate.
