摘要:
An abrasive article and methods of making and using the same are disclosed. The abrasive article includes a plurality of features on a backing. The features have a base and a body. The body is defined by sidewalls having parabolic sections. In some embodiments, the sidewalls are defined by a series of inner-connected lines segments approximating a parabolic section.
摘要:
A method and apparatus for knurling a workpiece in which the knurl pattern has an oblique helix angle relative to the longitudinal axis of the cylindrical workpiece. Also disclosed is a method of molding a molded article with the knurled workpiece to impart the inverse of the knurl pattern onto the molded article, such a molded article, a method of forming a structured abrasive article with the molded article, and such an abrasive article.
摘要:
A developer composition capable of developing electrostatic images on dielectric surfaces is disclosed. The composition has an electrical conductivity of at least 10.sup.-6 ohm.sup.-1 centimeter.sup.-1 and utilizes a small dimension powdered material as a coating on the essentially smooth surface of individual spheroids of a toner. The composition reduces background coloration on finished copies and eliminates the need to bias the magnetic development roll.
