摘要： A circuit for regulating an anode voltage (EHT) in an information display apparatus. A horizontal deflection circuit (10) has trace and retrace modes of operation. The horizontal deflection circuit further has a fixed retrace capacitance (CR1); and a series combination of a switched retrace capacitance (CR2) and a switch element (TR1), which combination is coupled in parallel with the fixed retrace capacitance. The switch element is in a closed position as the horizontal deflection circuit enters the retrace mode of operation. A voltage divider network (R1, R2) samples the anode voltage. A control circuit (20) is responsive to the sample voltage (V1) for controlling the switch element, such that the control circuit effects regulation of the anode voltage by selecting a time during the retrace period at which to place the switch element in an open position. The control circuit may also provide a raster width compensation voltage for an east-west pincushion correction circuit.

摘要： A graphical on-screen display (OSD) system, includes a decoder for decoding graphical OSD image representative data from an auxiliary information component of a video signal. An edge detector is coupled to the decoder and processes the OSD image representative data to detect an edge in the graphical OSD image. An edge smoother is coupled to both the decoder and the edge detector and generates signals representing a reproduced OSD image having a smoothed edge when an edge is detected.

摘要： A method of electrophotographically manufacturing a luminescent screen assembly on an interior surface of a faceplate panel (17) of a color CRT (10) includes the steps of: coating the surface of the panel with a conductive solution to form a volatilizable organic conductive layer (32), and overcoating the organic conductive layer with a photoconductive solution to form a volatilizable photoconductive layer (34). The conductive solution comprises the organic polymer 3,4-polyethylene dioxythiophene polystyrene sulphonate (PEDT/PSS); a methanol-soluble polymer or co-polymer selected from the group consisting of polyvinylpyrrolidone (PVP), poly (vinyl pyridine-co-vinyl acetate) (PVPy-VAc), polymethacrylic acid (PMAA), poly (hydroxyethylacrylate-co-methacrylic acid) (PHEA-MAA) poly (2-hydroxyethyl methacrylate) (PHEMA) and polyvinylbutyral (PVB) to reduce organic residue; and a solvent.

摘要： The present invention relates to a color cathode-ray tube (10) having an evacutated envelope (11) with an electron gun (26) therein for generating at least one electron beam (28). The envelope (11) further includes a faceplate panel (12) having a luminescent screen (22) with phosphor lines on an interior surface thereof. A uniaxial tension focus mask (25), having a plurality of spaced-apart first metal strands (40), is located adjacent to an effective picture area of the screen. The spacing between the first metal strands defines a plurality of slots (42) substantially parallel to the phosphor lines of the screen. Each of the first metal strands across the effective picture area of the screen has a substantially continuous first insulator layer (64) on a screen-facing side thereof. A second insulator layer (66) overlies the first insulator layer. A plurality of second metal strands (60) are oriented substantially perpendicular to the first metal strands and are bonded thereto by the second insulator layer. The first insulating layer has a coefficient of thermal expansion substantially matching, or slightly lower than, that of the first strands. The second insulating layer has a coefficient of thermal expansion that is substantially identical to that of the first insulating layer.

摘要： A device and a method for obtaining a corrected servo control signal in a servo control loop take in account a dynamical behaviour of the servo control signal (43) to calculate a new extremum (44) for this signal. If the servo control signal for any reason goes beyond the extremum (44) then it is corrected by replacing it with the value of the extremum. Depending on the difference (Δ) between the servo control signal (43) and the extremum (44) the new extremum may be greater or smaller than the previous extremum value. The extremum may be a maximum or a minimum thus limiting the servo control in its maximum or in its minimum value.

摘要： A step-up coil of a high-voltage transformer for powering a cathode-ray tube comprises windings housed in chambers (79) of a coil former (72). These windings are made in pairs (55, 56). The inner end (57) of the first winding of the pair is connected to an electrode (58, 60) of a first diode (59), the inner end (61) of the second winding of the pair is connected to the electrode (62, 64) of like nature of the second diode, or alternatively, the outer end (75) of the first winding (51) of the pair (55, 56) is connected to an electrode (58, 60) of the first diode (59), the outer end (65) of the second winding of the pair being connected to the electrode (62, 64) of like nature of the second diode (63).
The inter-winding capacitances of the windings of the pair are thus non-activated, the corollary of this being a decrease in the value of stray oscillations of the output voltages.

摘要： Disturbance detection is used to detect anomalies in the behaviour of the data signal. The data signal may for example be a readout signal in an optical drive. An upper and a lower envelope signal value for the data signal (4) are determined in a determined time interval (Δ(m - 1)). During the following time interval (Δ(m)) a difference value is computed by substracting from each other the values of the lower (s7) from the upper (s6) envelope signals. A disturbance is detected in case the difference value is smaller than a predetermined border value (5).
