    Abstract: An apparatus for developing an electrostatic latent image with liquid developing material. The apparatus includes a liquid developing material coating flow applicator for applying a substantially uniform coating of liquid developing material to a moving surface, wherein a housing, situated proximate to the moving surface, includes a fluid transport channel having a relatively narrow-width elongated outlet port for delivering a flow of liquid developing material to the moving surface, and an air flow channel having an elongated inlet aperture located adjacent the moving surface and immediately upstream from said outlet port for applying vacuum pressure to the flow of liquid developing material for varying the profile of the coating flow to provide variation of flow stability as well as thickness. A discussion of the effects of variations in the outlet port geometry, in particular, increasing the dimension between the downstream wall and the surface to be coated, has also been provided. A developing roll situated adjacent to and downstream from the liquid developing material is also provided for attracting the liquid developing material to image areas of the electrostatic latent image.

    Abstract: An apparatus for maintaining a uniform temperature along its axis by increasing the heat transfer efficiency. The apparatus uses a sealed chamber containing a substantially pure working fluid in a two phase (liquid and vapor) condition. The vaporization and condensation of the fluid increases the heat transfer efficiency and tends to equalize temperature gradients in a body in contact with the apparatus. The apparatus is utilized in various locations in an electrophotographic printing machine and can be used as a pressure roll for a heat and pressure fuser, a support or drive roll for a photoreceptive member, a support member for a photoreceptor and a heat sink for a developer housing.

    Abstract: A method and apparatus is described for removing excess liquid from an image receptor. As the image receptor moves at a certain velocity in one direction, a vacuum source or a source of positive air pressure effects air flow in a direction parallel to and opposite that of image receptor movement. The air flow is effected at a velocity greater than that of the image receptor movement. A channel is defined adjacent the receptor surface in which a pressure gradient is established for driving the air flow and causing the liquid layer to thin.

    Abstract: A piezoelectric bimorph scanner is disclosed which has a flexural beam attached to the free end of a cantilever mounted piezoelectric bimorph crystal. A mirror is bonded to the flexural beam a predetermined distance from the bimorph crystal. An AC voltage of predetermined frequency is applied to the bimorph crystal causing the flexural beam to oscillate with a node at the center of the mirror. The mirror rotates about the node rather than swinging in an arc, enabling the scanner to deflect a collimated light beam over a larger deflection angle than heretofore possible without additional light beam control apparatus. In an alternate embodiment, a laser diode may be mounted on the flexural beam instead of the mirror, further reducing costs and components.
