Abstract:
Disclosed are ionographic imaging apparatuses and processes. One apparatus comprises an imaging means (1), means (5) for applying to the imaging means a liquid material capable of forming a dielectric peel layer adhering to the imaging means, ionographic writing means (7) for generating a latent image on the peel layer, means (9) for developing the latent image on the peel layer, and means for simultaneously transferring the peel layer bearing the developed image from the imaging means to a substrate (15) and affixing the peel layer bearing the developed image to the substrate. In another embodiment, the apparatus employs a process which comprises applying to an imaging means a liquid material capable of forming a dielectric peel layer adhering to the imaging means, forming a first latent image on the peel layer with an ionographic writing means, developing the first latent image with a first developer, forming a second latent image on the peel layer containing the first developed image with an ionographic writing means, developing the second latent image with a second developer, forming a third latent image on the peel layer containing the first and second developed images with an ionographic writing means, developing the third latent image with a third developer, and simultaneously transferring the portion of the peel layer that bears the developed images to a substrate and affixing the peel layer bearing the developed images to the substrate. A further embodiment is directed to an apparatus and process for sequentially forming and developing primary color images on an imaging means to form a full color image, followed by transferring the fully formed image to a substrate, wherein the developers employed contain a release agent.
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.

PROBLEM TO BE SOLVED: To provide a method of leveling an ink on a substrate, and apparatus that is useful in printing and can generate quality printed images on many kinds of substrates.SOLUTION: The method includes a step of irradiating the ink 144 disposed on a first surface of a porous substrate 140 with radiation 122 emitted by at least one flash lamp. The radiation flash 122 heats the ink 144 to at least a viscosity threshold temperature of the ink 144 to allow the ink 144 to flow laterally on the first surface to produce leveling of the ink 144. The ink 144 is heated sufficiently rapidly, heat transfer from the ink 144 to the substrate is sufficiently small during the leveling, the ink 144 on a substrate interface is cooled to a temperature below the viscosity threshold temperature, thereby preventing any significant ink 144 permeation into the substrate 140 from the first surface.

Abstract:
PROBLEM TO BE SOLVED: To provide a carrying device capable of coping with a problem in a conventional carrying device wherein a sheet discharged from a fusing station is hot. SOLUTION: A carrying channel 32 is formed to feed a sheet S from a place where a sheet temperature is high in a copying machine to another place on the downstream side of the place. Several air drag coolers 10 are installed in the carrying channel 32, and its plenum 14 is connected to an air flow source through an inlet manifold 20. The air drag coolers 10 are allowed to communicate with the carrying channel 32 through an opening, for example, a slot 26 extending along the crosswise direction of the sheet in the carrying direction disposed between the inlet and the outlet of the sheet carrying channel 32. The sheet S fed into the carrying channel 32 is first fed along the sheet carrying direction and cooled by an air flow fed into the carrying channel 32 by the air drag coolers 10 through the slot 26.

Abstract:
PROBLEM TO BE SOLVED: To provide a passive means which decreases heating and cooling requirements by efficiently transferring heat from high-temperature portions to low-temperature portions of a transfuse member. SOLUTION: A heating roll 72 which heats the transfuse member 28 by coming into contact therewith and a cooling roll 73 which cools the transfuse member 28 by coming into contact therewith are included in a transfuse station which transfers the toner images of a printer to the transfuse member 28 and melts the same and further a phase transition roll 74 which heats the portions of the transfuse member 28 heading toward the heating roll 72 by coming into contact therewith and cools the portions of the transfuse member 28 heading toward the cooling roll 73 by coming into contact therewith is included therein. This phase transition roll 74 efficiently and passively transfers the heat from the portions for cooling the transfuse member 28 to the portions for heating the same.

Abstract:
PROBLEM TO BE SOLVED: To detach paper from a fixing member using an air knife under the optimum conditions. SOLUTION: A software means 550 contains a software object 560 which determines a first angle (ϕ), a second angle (θ), a distance (d), and a pressure of the air knife, when compiled. The software means 550 can be also used for generating a set of commands for performing front edge acquisition and positioning the air knife 250 at an optimum position for a medium and a fixing roll. A storage device concretely holds an object or a module for determining an optimizing parameter if given with an acquired setoff parameter from a user or a detection device. When software determines the optimizing parameter, a control signal 50 is generated so that the air knife 250 may be positioned at the optimum position of the job and the medium adopted by the job.
