    摘要: A system for regulating the transfer impedance of a plurality of current-to-voltage converters to a substantially equal value includes a reference voltage source and a reference impedance for providing a reference current. A reference current-to-voltage converter is responsive to the reference current and provides an output voltage. A comparator is responsive to the reference voltage and the output voltage and provides a control signal to the reference current-to-voltage converter and to all the other current-to-voltage converters to maintain the transfer impedance of all the current-to-voltage converters constant.

    摘要: A memory and a switchable digital filter supply different numbers of digital distortion correction values. The supplied distortion correction values are converted to an analog distortion correction signal. A passive, analog low pass filter for the analog distortion correction signal generates an analog deflection signal. The low pass filter is optimized only for those of the analog deflection signals having a given sample rate. A controller varies the different numbers of the supplied distortion correction values to maintain the given sample rate of the analog deflection signal for different horizontal scanning rates. The controller selectively implements respective operating modes for different horizontal scanning frequencies in which no interpolated distortion correction values are supplied or different numbers of interpolated distortion correction values are supplied.

    摘要: In a multi-winding motor of the type which develops switching spikes from respective drive signals, separate interference suppression apparatus is not provided for each motor winding to be triggered, but rather interference suppression circuitry is shared between respective winding drive signal paths. In a first arrangement, a single resistor-capacitor impulse suppression network is commutated between all motor winding connections in predetermined phase relation with the application of drive currents to the respective windings. In a further arrangement, a single impulse suppression circuit is used to cyclically couple the respective low power motor trigger signals to the respective high power winding drive amplifies, which suppression circuit precludes the generation of interference pulses at the interface between the drive circuitry and the motor to be driven.

    摘要: A method of collecting the spactial positions of crossing points of the lines in the grid on the visible portion of the screen of a television receiver used in different modes of operation includes the steps of storing a first set of correction values for each of the crossing points. The first correction values define the spactial positions of the correction points for all modes of operation of the television receiver. Additional correction values are stored for each mode of operation. The additional correction values are generated during an overscan period and during the scanning of an initialization line which is positioned outside the visible portion of the screen and compensate for displacement of the crossing points induced by tolerances in the tube. The first correction values and the additional correction values are simultaneously applied to the deflection current of the television tube while the visible portion of the screen is scanned.

    摘要: A cable (K) comprises at least one lead (A) and at least one insulating layer (I). In communication technology, communications are transmitted between two apparatuses by cables of various types. In order to reduce to a minimum the number of cables and cable connections necessary, cables with a high transmission capacity are preferred. In order to substantially increase the transmission capacity of a cable (K) with at least one lead (A) and at least one insulating layer (I), the insulating layer (I) is made for optical transmission purposes of an optically conductive material. Optical transmission channels can be obtained using optically conductive materials for the insulating layers of all cables with one or more insulating layers, for example flat cables, coaxial cables, mains cables, etc., without having to increase the cross-section of the cable or to provide separate connections for additional cables in the appliances to be connected.

    摘要: An arrangement for compensating against changes in parameters of an optical emitter and an optical receiver in an optical scanner that detects different luminosities. The optical receiver is exposed to light from the optical emitter and provides an output voltage that is compared with a reference voltage. The output voltage is clamped to the reference voltage when the light received by the optical receiver has energy of an extreme value. The receiver detects light of varying brightness between maximum brightness and minimum brightness, and will operate at any durations of varied brightness levels. The receiver distinguishes between maximum brightness and minimum brightness, and when the brightness has a step-shape, a stair-shape function is provided by the receiver output voltage. The output voltage of the receiver is clamped to the reference voltage when the light energy received by the optical receiver attains either a maximum or a minimum.
