摘要： A speed-up circuit 10 is connected to a detection line 6 for feeding back the high voltage detection value of a high voltage detection circuit 5 to a high voltage stabilizing circuit 1. When a power supply switch is turned on, since a PNP transistor 12 of the speed-up circuit 10 is turned on, a resistor 11 is connected to the detection line 6, so that the high voltage detection value is reduced forcedly. Accordingly, the high voltage stabilizing circuit 1 increases the peak value of a flyback pulse generated by a resonance-type power supply circuit 2 to output higher high voltage thereby to shorten the rising time of the high voltage output supplied to the anode of a CRT. After the lapse of the predetermined time from the turning-on of the power supply switch, since the terminal voltage of a capacitor 13 having been charged through a resistor 14 exceeds almost the voltage at a point A, the PNP transistor 12 is turned off, so that the resistor 11 is separeted from the detection line. Accordingly, the responsibility of the flyback pulse is prevented from being degraded at the time of the abrupt change of the load of the CRT.
摘要翻译：加速电路10连接到检测线6，用于将高电压检测电路5的高电压检测值反馈给高电压稳定电路1.当电源开关导通时，由于PNP晶体管12 加速电路10接通，电阻器11与检测线6连接，使得高电压检测值被强制地减小。因此，高电压稳定电路1增加由谐振型电源电路2产生的回扫脉冲的峰值，以输出较高的高电压，从而缩短供给CRT的阳极的高电压输出的上升时间。在从供电开关接通经过预定时间之后，由于已经通过电阻器14充电的电容器13的端子电压几乎超过了点A处的电压，所以PNP晶体管12截止，使得电阻器11从检测线分离。因此，在CRT的负载的突然变化时防止回扫脉冲的作用降低。

摘要： A high voltage transformer (Tr) includes a primary winding (Lp), secondary windings (Ls1, Ls2, Ls3), and diodes (Di) coupled between successive secondary windings. The polarity of the diodes and the secondary windings is selected such that the flyback voltages across each of the secondary windings are summed via conductive diodes during at least a part of a flyback period (Tf) for generating a high voltage. A damp-circuit (1) comprises a rectifier element, a load (L), and a further winding (Ls4) of the high voltage transformer. These elements are arranged with respect to one of the secondary windings such that the further winding and the one of the secondary windings form a capacitance (Cd) across the load. The diode (D) is non-conductive during the flyback period. In this way, electrical oscillations of the high voltage transformer are damped.

摘要： In a video display operable at multiple horizontal scanning frequencies, a synchronized high voltage generator is substantially undisturbed during synchronizing source selection or interruption. The generator comprises a controlled oscillator generating a drive signal. A source of pulses synchronizes the controlled oscillator and has a plurality of scanning frequencies. A high voltage generator is coupled to the drive signal and generates a display energizing supply. The scanning frequencies occur in two frequency bands, and when synchronized the oscillator generates the drive signal having a frequency only in a higher frequency band of the two frequency bands. In a further inventive arrangement a high voltage generator for a video display is operable at a plurality of horizontal scanning frequencies and is controlled such that the high voltage supply remains substantially constant during an interruption of horizontal scanning pulses from the source.

摘要： A one-dimensional p-th order spline waveform (Cw) extending along the width or height of a picture device display screen is generated as a chain of sections of p-th order sub-functions (Sfi) of a position address (P). If n predetermined values (ai) are available, n-p p-th order sub-functions (Sfi) can be generated each in one of n-p sections (Si). q.gtoreq.(p+1) values (asi) are selected from an array containing the n predetermined values (ai) and then the q selected values (asi) are converted into sub-function coefficients (bi) determining each of the p-th order sub-functions (Sfi). Each of the p-th order sub-functions (Sfi) can be written as a linear combination of polynomials of the position address (P) multiplied with associated sub-function coefficients (bi). Further, each of the p-th order sub-functions (Sfi) can be imagined to be obtained by an addition, in a section (Si), of portions (pi) of basic functions (Fbi) each multiplied by an associated one of the predetermined values (ai). The basic functions (Fbi) are p-th order spline functions. Each of the portions (pi) of the basic functions (Fbi) is written as a linear combination of portion coefficients (cij) corresponding to polynomials of the position address (P). The polynomials range from zero order up to the p-th order. The portion coefficients (cij) determine the shape of the basic p-th order spline functions (Fbi). Each of the sub-function coefficients (bi) can be calculated from the selected values (asi) by multiplying a matrix including the portion coefficients (cij) with the selected values (asi). The matrix must be a spline matrix to obtain sub-functions (Sfi) together composing the spline waveform (Cw). The process of converting the selected values into one of the sub-function coefficients is the same in every section (Si) since a fixed matrix of portion coefficients (cij) or multiplication factors is used.
