Abstract: A method and system for fabricating an array of electronic devices, typically a display or sensor is described. In the method, a droplet source ejects droplets of a masking material for deposit on a thin film or substrate surface to mask an element of the array of electronic devices. The temperature of the thin-film or substrate surface is controlled such that the droplets rapidly freeze upon contact with the thin-film or substrate surface. The thin-film or substrate is then etched. After etching the masking material is removed.

Abstract: An improved counter electrode assembly for an electrostatic recorder in which the recorder applies electrical charges, in image configuration, upon a movable image recording member by means of a stylus electrode array and a counter electrode assembly aligned with one another and between which the image recording member may be moved. Both the stylus electrode array and the counter electrode assembly are positioned so as to extend transversely to the direction of movement of the image recording member. The counter electrode assembly comprises a support member, an elastica sheet member anchored to the support member and bowed toward the stylus electrode array, and an electrically resistive member urged by the elastica sheet toward the stylus electrode array.

Abstract: An optical fiber cabinet for enclosing various optical fiber connections and/or terminations. The optical fiber cabinet includes a frame which defines an optical fiber connection-termination area with the frame including a base having a bottom opening, vertical support members, and a removable upper frame member. Clam-shell doors are rotatably attached to the vertical support members of the frame and have a closed and open position. In the closed position, the clam-shell doors cooperate with the frame to enclose the optical fiber connection-termination area. In the open position, the clam-shell doors are disposed away from the optical fiber connection-termination area to allow both horizontal and vertical access to the optical fiber connection-termination area. A connection box within which the optical fiber connections are mounted is disposed within the optical fiber connection-termination area of the cabinet and includes a door rotatable between a closed and open position.

Abstract: An apparatus for selectively setting the distance between the write head of an electrographic printing apparatus and a recording medium in combination with the use of a gas, present in the gap between the medium and the write head whereby the gas has a Paschen curve minimum lower than the Paschen curve for air. The combination of increasing the distance of the head from the medium along with the use of a gas as specified decreases the amount of flare while decreasing dropout and maintaining image density.

Abstract: An electrostatic recorder for applying electrical charges, in image configuration, upon a movable image recording member, the recorder including a stylus electrode array and a counter electrode array which electrode arrays are aligned with one another on opposite surfaces of the image recording member and are positioned so as to extend across the direction of movement of the image recording member. The counter electrode array comprises a base member supporting a plurality of electrically conductive traces thereon, each extending substantially in the direction of movement of the recording member. The conductive traces are interconnected by a layer of resistive material, and contact pads are connected to periodically spaced conductive traces so as to apply electrical potentials to spaced regions of the counter electrode array. Those conductive traces located intermediate the periodically spaced conductive traces are electrically floating when electrical potentials are applied to the spaced conductive traces.

Abstract: In a device for producing an electrostatic image along a scan line of a recording medium by means of a recording device including an array of stylus electrodes arranged in a series of groups cooperable with a series of complementary electrodes, each of the stylus electrode groups cooperates with a portion of two adjacent complementary electrodes whereby writing is accomplished by imposing a charge pattern upon the recording medium in the region of a stylus electronic group when both the stylus electrode group and its cooperating pair of complementary electrodes are actuated contemporaneously. As each complementary electrode is actuated it induces a non-uniform residual potential distribution in the recording medium of a portion of the region of the next adjacent stylus electrode group.

Abstract: A preferred embodiment of the present invention is directed to a removal of a ghost image created during a processing of a film laminate medium by an electrographic plotter. A recording of an image on the film medium induces a ghosting potential over a developing station. The ghosting potential causes a spurious image to be developed by the developing station.The recorded image is created by depositing a charge on a dielectric layer of the film. A relationship exists between the deposited charge and the ghosting potential. By use of information known to the system, the ghosting potential may be estimated and reduced. A preferred method estimates the magnitude of the ghosting potential by use of the relationship between deposited charge and ghosting potential. A counteracting potential is applied to the system to reduce the ghosting potential over the developing station. The reduction of the ghosting potential substantially removes the ghost image created during the processing of the film laminate.

Abstract: A method of producing an electrostatic image along scan lines of a recording medium with recording means including a series of stylus electrodes arranged in a longitudinally extending array and divided into two groups, with the stylus members of each group being connected in parallel with one another along the array. A series of complementary electrodes is arranged in a longitudinally extending array and cooperates with sets of stylus electrodes for depositing a charge pattern upon a selected region of recording medium when the sets of stylus electrodes and selected complementary electrodes are pulsed contemporaneously. The method comprises the steps of delivering data, comprising a writing potential or a non-writing potential, to the stylus electrodes of both groups, and overriding certain of the data with a non-writing potential for defining the sets of stylus electrodes within the groups.

Abstract: A telephone network interface device having differing means for access for the public utility, building owner or apartment manager, and those living in individual housing units; differing means of access provided in part by a latchpiece inserted between a first gate leading to a subscriber compartment and a second gate leading to the utility compartment. Also described is a container using the latchpiece.
