摘要： A full-frame flash illumination and imaging system wherein an illumination mechanism compensates for unwanted charge variations on a photoreceptor belt caused by reflections of the lens from the document platen. The area of the belt upon which the negative lens image is formed is predetermined and a controlled quantity of light is directed towards this area, either before, after, or during exposure, to reduce the charge level of the area, to the degree necessary to compensate for the negative lens image. Several illumination mechanisms are disclosed including a programmable LED array and various mask configurations.

摘要： A FreeTherm thermal energy storage system includes an ice-water shallow pool used for storing and extracting thermal energy cyclically, by thawing the ice and freezing water intra-seasonally. A series of heat extractors positioned within the shallow pool are adapted to extract heat during the formation of ice. Bladders are connected to the heat extractors and also connected to a conventional heat pump and have an anti-freeze mix that is maintained at sub-freezing temperatures flowing through their interiors to remove heat from the heat extractors. The extractors have concave-downward surfaces for extracting heat from water to produce ice. The heat extractors are made of flexible material that can be expanded to release ice from their surfaces, and are adapted to pivot up and out of the way to allow the released ice to float to the top of the reservoir. During the summer cooling cycle, convection assisted insulated tower and program of upward airflow is used to deliver heat from a thermal reservoir of water through a heat exchanger to relatively cooler outdoor air. The heat exchanger is used to refresh the thermal reservoir with cool water during periods when the outdoor air is substantially cooler than the water in the reservoir.

摘要： A method and apparatus for reproducing color images using a non-interactive pyroelectric imaging process is disclosed. More specifically, the present invention is used to generate multiple layers of toner on the top surface of a pyroelectric imaging member without physical contact to the imaging member top surface. The ability to generate a composite image with different materials in this manner enables printing machines to use a pyroelectric imaging process to generate color images in the image on image (I-O-I) mode.

摘要： A multi-color printer using a stretch toner release development system to provide either partial or full color copies with minimal degradation of developed toner patterns by subsequent over-development with additional colors and minimal back contamination of developer materials. Multiple scanning beams, each modulated in accordance with distinct color image signals, are scanned across the printer's photoreceptor at relatively widely separated points, there being a buffer provided to control timing of the different color image signals to assure registration of the color images with one another. Each color image is developed prior to scanning of the photoreceptor by the next succeeding beam. After developing of the last color image, the composite color image is transferred to a copy sheet. Development is accomplished by stretching the surface of a toner carrying member and thereby reducing the net force of adhesion of toner to the surface of the toner carrying member.

摘要： A cleaning device for an electrostatographic copying machine collects residual toner from a photoconductive surface of the copying machine by the use of fiber-like bristles adhered to a face of a slit through which air is pulled by a vacuum pump. The bristles are pressed gently into sliding contact with the imaging surface and thereby loosens the toner for capture by the vacuum pump through the slit. An alternative would be to use open-cell foam in place of the bristles.

摘要： A novel induction-type electrostatic generator is disclosed in which moving electrodes are transported back and forth between two Faraday cages. Each moving electrode, once enclosed by a cage, is contacted to the cage, then separated by more than the sparking distance before making electrical connection to the opposite moving electrode or to ground. In this way, charge opposite in polarity but proportional in magnitude to the charge on each cage, is induced in each moving electrode and carried into and imparted onto the next cage, progressively elevating the cage potentials until the corona or arcing limits are reached. Initiation of charging is spontaneous, deriving from inevitable statistical imbalances in nature.

摘要： Electrorheological based acoustic droplet ejectors and their applications in acoustic print heads are described. The droplet ejectors include an acoustic transducer which generates acoustic energy into a fluid well holding an electrorheological fluid such that the fluid's free surface is adjacent electric field electrodes. The acoustic energy is such that droplets are ejected from the fluid as long as a lower voltage is applied to the electrodes. However, when a higher voltage is applied to the field electrodes, the electrodes produce an electric field through the fluid which causes the viscosity of the fluid to increase sufficiently that droplet ejection is prevented. When used in a print head, the electrorheological fluid is an ink. Further, many (perhaps thousands) of individual droplet ejectors are formed in the print head. By controlling droplet ejection from the individual print heads, an image can be produced on a recording medium.
