摘要： An electrostatic latent image is impressed on a multilayer apertured screen to establish within the apertures electric fields that modulate the passage of charged particles through the screens so that the charged particles are distributed in correspondence with the image. After imaging the screen is operated to control the gray scale response thereof in order to optimize copy quality. The gray scale screen response is expanded by applying a bias voltage of at least two different values to the screen during the duplication interval. The response is limited by altering the latent image charge to provide a high density cutoff and by applying a bias voltage to establish a low density cutoff during the duplication interval. Copy quality is further improved by adjusting the integrated charged particle current to establish the desired degree of density in regions of the copy image corresponding to high density regions of the original image.

摘要： The invention basically comprises systems and methods relating to the field of electrostatics and is concerned with multicolor electrostatic reproduction, printing or constituting on coated and uncoated print receiving media with multilayer apertured elements or screens carrying charge distributions in accordance with selected color separation patterns. Ions accelerated through the apertures of the multilayer element pass therethrough under modulation control dictated by the color separation pattern, thereby forming a modulated ion stream having a cross-sectional density pattern corresponding to the color separation pattern. Electrostatic latent images are formed with modulated ion streams and are developed in various ways. In one embodiment, a modulated ion stream is accelerated by an electrostatic field through a mist of uncharged liquid toner particles which are charged by collision with the ions and then accelerated by the ion accelerated field toward and onto the print receiving medium, which may be ordinary uncoated paper. In another embodiment, the modulated ion pattern is projected onto a dielectric surface in the electrostatic accelerating field to form an undeveloped latent electrostatic color separation image thereupon. The dielectric surface may be a dielectric coating on the print receiving medium itself. In another embodiment, the dielectric surface may be formed on an intermediate transfer drum and the print receiving medium laid over the image on the drum and the image transferred and fixed to the print receiving medium with heat and pressure.

摘要： An electrostatic line printing process employing multilayered particle modulator comprising a layer of insulating material on one side of the insulating layer and a segmented layer of conducting material on the other side of the insulating layer. At least one row of apertures is formed through the multilayered particle modulator. Each segment of the segmented layer of conductive material is formed around a portion of an aperture and is insulatively isolated from every other segment of the segmented conductive layer. Selected potentials are applied to each of the segments of the segmented conductive layer while a fixed potential is applied to the continuous conductive layer. An overall applied field projects charged particles through the row of apertures of the particle modulator and the density of the particle stream is modulated according to the pattern of potentials applied to the segments of the segmented conductive layer. The modulated stream of charged particles impinge upon a print-receiving medium interposed in the modulated particle stream and transplated relative to the particle modulator to provide line-by-line scan printing.

摘要： In a magnetic recording system, an asymmetry detector reverses the phase of a read, single-frequency test signal to indicate to a micro-controller whether recording signal asymmetry is present. Upon detecting such asymmetry, the micro-controller causes a current source coupled to the recording head to adjust a write current to correct the timing of a written data signal.

摘要： An improved electrostatic print head is disclosed comprising a corona source, an aperture mask, a slotted focus plane, and a back plane electrode for supporting a moving dielectric print medium. The aperture mask includes two rows of staggered circular apertures which are surrounded by individual aperture electrodes on the side of the mask facing away from the corona source. The side of the aperture mask facing the corona source has a continuous conductive layer thereon which is biased at a fixed potential. The aperture electrodes are selectively pulsed with a control potential to control the flow of ions from the corona source through the two staggered rows of apertures and the slotted focus plane to form any desired dot-matrix latent image on the moving dielectric print medium. The center line of the slotted focus plane is parallel to the center line between the two staggered rows of apertures to focus the ion beams defined by the individual apertures toward the center line of the slot while intensifying the electric field in the imaging region. The slotted focus plane also compresses the cross section of the ion beams defined by the individual apertures into ellipses having their minor axes parallel to the direction of motion of the dielectric print medium, permitting higher ion densities to be deposited on a moving dielectric print medium for a given final dot size and an improved resolution of the final dot-matrix image.

摘要： A system for controlling the flow of charged particles and for modulated aperture electrostatic printing. An apertured screen having substantially the entire surfaces formed of a dielectric material is charged with like charges over substantially all of its surfaces to develop fringing fields in the apertures. The charge distributed across one side of the screen is selectively dissipated in accordance with the pattern to be reproduced, thereby modifying the fringing fields to form an electrostatic latent image for controlling a flow of charged particles directed to the screen. The screen is initially pre-image charged to carry a higher potential V.sub.A on one face than on the other V.sub.B to provide a potential difference V.sub.A - V.sub.B through the screen apertures. This is accomplished by constructing the screen to have a lower insulator capacitance on side A than on side B; or, to have a greater insulator resistance on side A than on side B; or by selecting the insulator material on side B to have a non-linear resistance characteristic at all voltage levels above the desired value for V.sub.B ; or, to have combinations of two or more of such characteristics. The pre-image charge is modified in accordance with an image to be reproduced, and, in some regions of the screen V.sub.A is reduced to less than V.sub.B. Full modulation control of particle flow is thereby possible with a single selective charge dissipation.

摘要： A game or test of skill which is comprised of three principal components: a playing surface that either conceals or suggests a secret pattern of paths, a probe for selecting points on the playing surface, and an indicator that reveals whether a selected point belongs on the pattern of paths. In a preferred form of the game the playing surface is a small card on which is marked a grid that indicates the possible positions and orientations of the concealed paths in the pattern. A start point is indicated on the grid; the player places a hand-held pencil-like probe at the start point and tries to find a continuous path from the start point to the end point. The probe leaves no mark on the card, but the player is aided by the indicator which provides a signal when the probe is on-path--the signal ceases abruptly if the probe is moved off-path. The end-point is reached when the probe arrives at a designated end-point line of the grid without an off-path indication, or a separate end-point signal (for example, a bell) can sound when the end-point is reached. The object of the game is to traverse the grid from start to end without once leaving a pattern path, and to do this in the fewest possible attempts.
