Definitions
- the latent electrostatic image on a xerographic plate is developed by applying a particulate pigmented developer material characterized in that its is attracted selectively by a latent electrostatic image.
- thermoplastic layer over the surface of the xerographic plate may be deformed by the effects of the latent electrostatic image and may then be displayed by the use of schlieren optics or the like.
- the image is erased by removal of the electrostatic image.
- the thermoplastic layer the image is formed by softening the layer in the presence of the latent electrostatic image and is later erased by removing the electrostatic latent image and softening the thermoplastic material.
- such a deformation image on a liquid or thermoplastic layer may be formed on such a layer that is spaced or separable from the Xerographic plate so that the layer may be removed from proximity with the xerographic plate, displayed, erased and then returned for reuse while the xerographic plate may be re-used during the timer interval.
- the present invention encompasses methods and means of deforming a separate or separable layer from the induction eifects of the electrostatic latent image on Xerographic plate.
- FIGURE 1 is a diagrammatic illustration of induction deformation of a liquid layer.
- FIGURE 2 is a diagrammatic illustration of induction deformation of a thermoplastic layer.
- FIGURE 3 is a diagrammatic illustration of induction deformation of the interface between a conductive liquid layer and an insulating thermoplastic layer.
- FIGURE 4 is a diagrammatic illustration of inductive deformation of the interface between an insulating liquid layer and a conductive thermoplastic layer.
- FIGURE 5 is a diagrammatic illustration of inductive deformation of the interface between an insulating liquid layer and a conductive liquid layer.
- FIGURE 6 is a diagrammatic illusrtation of inductive deformation of the interface between a conductive thermoplastic layer and an insulating thermoplastic layer.
- xerographic plate 10 carries latent electrostatic image 13. This image may be previously formed in a conventional Xerographic manner as by electrostatically charging photoconductive insulating layer 12 and exposing the layer to an image pattern to selectively dissipate some of the charge.
- the xerographic plate as shown comprises layer 12 of a photoconductive insulating material such as vitreous selenium, zinc oxide in a.
- layer 12 has been charged positively and the charges have been dissipated in the areas where the layer has been illuminated.
- the charges remaining after forming the electrostatic latent image emanate fields or lines of force in the direction of available charges of the opposite polarity.
- these positive charges as illustrated will emit lines of force in the direction where there are no charges indicated on the surface of the layer or else down through the layer to the conductive layer underneath.
- xerographic plate 10 bearing the latent electrostatic image is maintained in the dark and is positioned on supports 14 immediately over the image plate 15 comprising a conductive layer 15 which may suitably be made of conductive paper, metal, or other conductive material, and a conductive liquid layerl7 such as water, alcohol, mercury, Aquadag (Acheson Colloids Corp.) a concentrated colloidal dispersion of pure electric furnace graphite in Water with a solids content of 22%, an average particle size of 0.5 micron and a maximum particle size of 4 microns, or a liquified conductive resin material.
- the two plates are positioned as closely together as possible while avoiding actual physical contact.
- gaseous space 19 is maintained between the adjacent surface preferably with a gap width of between 1 and 5 mils.
- a narrower gap width presents too great a problem in precisely positioning the plates and raises the probability of dielectric breakdown which produces image defects.
- a gap width exceeding about 5 mils reduces the field effects obtained, lowers the quality of the reproduced image and reduces resolution and contrast.
- the lines of force emanating from the latent electrostatic image find a proximate point of opposite polarity charges in the liquid layer 117 and exert the physical forces of attraction on those charges producing a deformation in the liquid layer.
- the surface of the liquid layer 17 is displaced in accordance with the latent electrostatic image to form a relief image 13.
- deformable layer 21 is appropriately a thermoplastic material such as glycerol ester of 50 percent hydrogenated rosin sold as Staybelite by Hercules Powder Co., styrene and styrene homologue resins and other thermoplasticmaterials preferably having softening temperatures between about 90 F. and 200 F. in order to maintain stability at room temperature and yet soften readily for image formation.
- thermoplastic material such as glycerol ester of 50 percent hydrogenated rosin sold as Staybelite by Hercules Powder Co., styrene and styrene homologue resins and other thermoplasticmaterials preferably having softening temperatures between about 90 F. and 200 F. in order to maintain stability at room temperature and yet soften readily for image formation.
- plastic materials are commonly electrically insulating but their conductivity is readily increased by appropriate additives.
- the plastic when there is no desire to pass light through the deformable layer, the plastic may contain carbon black or like conductivity agent such as a colloidal graphite suspension.
- the relatively conductive deformable layer is described as conductive. This is not intended to mean conductive in the general sense, but rather specifically to the electrophotographic art.
- conductors are considered to have resistivities of less than 1 ohm-cm.
- Semiconductors are considered to occupy the range upto 10 ohm-cm. and materials with still higher resistivities are considered insulators.
- insulators are generally considered to be materials having resistivities of 10 ohmcm. and higher with materials capable of some charge retention having resistivities higher than 10 ohm-cm.
- the deformable layer 21 is supported by a conductive layer 22 against which is appropriately positioned a heating element 23.
- the deformable layer can be liquified by energizing heating element 2.3.
- the deformable layer will deform in the image pattern as described in connection with FIGURE 1 during the liquid phase, and then upon deenergization of the heating element the deformable layer will freeze in the image pattern and may be removed from the presence of the latent electrostatic image for separate use. Re-heating in the absence of the latent electrostatic image will cause complete erasure of the image.
- FIGURE 3 An embodiment of the invention for simultaneous formation of both the latent electrostatic image and the induction deformation image is illustratedin FIGURE 3.
- the embodiment of FIGURE 3 has the advantage of not requiring separate movement of the xerographic plate 10 and the image plate 15 during the process steps.
- a further advantage is that no corona charging is used, reducing the required voltage, equipment, and process steps. Also, this can work in a vacuum Where corona charging isnot possible.
- a xerographic plate 10 such as described in connection with FIGURE 1 is positioned in a sandwich with a deformable insulating layer 25 and a conductive liquid layer Zn in turn supported by a conductive backing 27.
- the deformable layer 25 which coats the conductive liquid layer 26 serves a dual function of providing a layer which may be frozen in a deformed condition and also providing an insulating barrier between the conductive liquid 26 and the photoconductive insulating layer 12. With this insulating barrier 25 it is possible to reduce the spacing between the photoconductive insulating layer and the conductive liquid layer down to a gap in the order of 5 microns 'or more. With this decrease in spacing gap as compared to the embodiment of FIGURE 1, improved image contrast and resolution is obtainable. As well as various thermoplastics listed in connection with FIGURE 2, the deformable layer 25 in FIGURE 3 is appropriately low melting point paraiiin. A voltage is applied between the conductive layers 11 and 27 from a voltage source 28.
- the desired effects may be obtained by a considerably lower potential so voltage source 28 is accordingly in about the range of 100 volts or higher.
- the limiting high voltage is one that would cause a dielectric breakdown in insulating layer 25 or photoconductive insulating layer 12.
- the sandwich of layers is heated as by a heating element 23 so as to liquify the deformable layer 25 to a highly compliant condition.
- the photoconductive insulating layer is exposed to a light image as by a projector 31 as illustrated in FIGURE 3.
- the backing layer of the xerographic plate is made of a transparent material such as glass coated with a conductive layer such as tin oxide.
- FIGURE 4 illustrates the variation of the embodiment of FIGURE 3 in which an insulating liquid layer 35 is positioned between the latent electrostatic image bearing surface and a conductive deformable layer 36.
- layer 36 is made of a material that is solid at room temperature and readily liquifies on the application of heat. This has a slight advantage over the embodiment of FIGURE 3 in that the thermally liquifiable layer 36 is closer to the heat source 23.
- the heating requirements are slightly less and there is less chance of deterioration of the xerographic plate lti due to repeated application of heat.
- FIGURE 5 The use of an insulating liquid and a conductive liquid is illustrated in FIGURE 5 in which an insulating liquid 38 is positioned in between the latent electrostatic image bearing surface and a conductive liquid layer 39.
- the conductive liquid may be water and the insulating liquid may be oil.
- the resistance against the deformation effects of the latent electrostatic image is produced almost entirely .by liquid viscosity and interfacial tension between the two liquids. Since materials may be selected to minimize interfacial tension, deformation is readily obtained enabling the use of lower voltages, thinner layers, and larger solid relief areas.
- both the insulating deformation layer and the conductive deformation layer are made of thermally liquifiable materials that are solidat normal room temperatures. With both of these layers made of a material such as thermoplastic, it is possible to strip them apart after the image has been formed and solidified so as to obtain two separate deformation images.
- the conductive layer would have a direct reading image while the insulating layer would have a mirror reverse image on its deformed surface.
- FIG- URE 6 as Well as in FIGURE 3 it is possible to use an insulating layer that is bonded permanently to the photoconductive insulating layer of the xerographic plate. However, this would require slightly different Xerographic steps from those customarily used. Thus, sensitizing the plate would have to be performed by a method such as disclosed in US. Patent 2,833,930 in which charge is induced to the photoconductor surface under illumination and then trapped at the surface by discontinuing the illumination.
- FIGURES 3, 4, 5, and 6 are all illustrated with a volt age source 28 applied across the conductive layers 11 and 27.
- the common electrical reference connections as shown in FIGURES 1 and 2 produce the desired results. It is also possible to charge plate 10, then sandwich the layers together, and then form the latent image by exposing with a light image through a transparent side of the sandwich. In this latter case, either a common reference as in FIGURES 1 and 2 or a voltage source 28 connected between layers 11 and 27 will establish the desired references for deformation.
