摘要： An East-West switching transistor is coupled between a flyback transformer primary winding and a horizontal deflection output transistor circuit to control retrace energy to obtain an East-West modulation of the deflection current amplitude as required for East-West pincushion raster correction. The East-West switching transistor isolates a retrace resonant circuit that includes a horizontal deflection winding from a flyback resonant circuit that includes the flyback transformer during a portion of retrace. The deflection winding is coupled to a common conductor to permit the use of a retrace voltage sample, developed in the deflection winding and coupled to the East-West switching transistor, to control the switching operation in a manner that bypasses the flyback transformer. A resistor coupled in series with the primary winding develops a voltage, during trace, that is indicative of beam current. The resistor voltage is coupled to the East-West switching transistor to prevent beam current variation from causing raster width variation.

摘要： A television receiver is controlled as to the degree of vertical zoom via a deflection current ramp that varies in slope and which may be delayed to achieve panning. Due to the increased slope when zoomed, the deflection current and the electron beam complete a trace in less time than the normal vertical interval. The deflection current is maintained at one extreme or the other outside the trace interval, and the beam is blanked. A retrace signal generator coupled in a feedback loop with the power supply for the deflection circuit determines the midpoint of the blanking period and generates a fast retrace at or near the midpoint. The feedback loop is arranged to minimize the DC average current in the deflection winding by having a current source responsive to the DC average current for charging a timing ramp that triggers retrace upon reaching a threshold. The slope of the timing ramp varies with DC loading, thus advancing or retarding retrace to center retrace in the blanking interval.
摘要翻译：通过斜率变化的偏转电流斜坡来控制电视接收机的垂直变焦度，并且可以延迟实现平移。由于变焦时斜率增加，偏转电流和电子束在比正常垂直间隔更短的时间内完成轨迹。偏转电流保持在跟踪间隔之外的一个极限或另一个极限，并且光束被消隐。耦合在反馈回路中的用于偏转电路的电源的回扫信号发生器确定消隐期的中点，并在中点处或附近产生快速回扫。反馈环路被布置成通过使电流源响应于DC平均电流来使偏转线圈中的直流平均电流最小化，以在达到阈值时触发回扫的定时斜坡。时序斜坡的斜率随直流负载而变化，因此在消隐间隔内推进或延迟回扫到中心回扫。

摘要： In the velocity modulation apparatus for a three-tube projection television, an effective velocity modulation can be implemented under due consideration of humans eye's relative visibility characteristics with respect to the three primary colors of R, G and B, and the velocity modulation apparatus includes a VM signal extracting circuit 1 for extracting a velocity modulation (VM) signal from the luminance signal; a plurality of driving circuits 3 to 5 having three different gains at ratios of 0. 3:0. 59:0. 11; and a red color VM coil 7, a green color VM coil 8 and a blue color VM coil 9 provided for three corresponding Braun tubes, respectively and driven by the driving circuits 3 to 5, respectively. Since the respective gains of the driving circuits 3 to 5 are previously determined in correspondence to the eye's relative visibility of the three primary colors of R, G and B, it is possible to perform the velocity modulation being based on the practical emphasis at picture image contours, and thereby to eliminate wasteful power consumption.

摘要： A dynamic correction arrangement for an electron beam projection/deflection system provides high order correction values for deflection in accordance with a correction equation. Particularly as applied to high accuracy telecentric deflection, the coefficients of terms of the correction equation may be determined by calibration for a small number of test points. Correction values may be stored in a look-up table or computed in real time by using a math co-processor in a processing pipeline. The correction provided corrects landing angle errors through the third order in telecentric projection/deflection systems such as systems utilizing variable axis immersion lenses.

摘要： A focus voltage correction circuit for cathode ray tubes is disclosed in which a flyback pulse is generated by switching a supply voltage to be applied to a primary side of a flyback transformer, and the flyback pulse being is rectified and smoothed so as to develop a focus voltage in cathode ray tubes. A correction voltage capable of minimizing an error in the focus voltage to be caused by an error in the supply voltage is superimposed on the flyback pulse. In addition, the focus voltage correction circuit for cathode ray tubes may be provided with a device for regulating the correction voltage such that the focus voltage regulation can be performed.
