摘要： A horizontal deflection and high voltage regulation system for CRT displays and television receivers utilizes a single horizontal output transistor driving a conventional deflection yoke and high voltage transformer. A diode modulator and pulse width modulating system is coupled to the horizontal deflection yoke to provide control of horizontal scan size. A separate diode modulator and pulse width modulator is coupled to the horizontal transformer. A comparator is coupled to a resistive high voltage divider to produce an error voltage indicative of CRT anode voltage. The error voltage thus developed is applied to the diode modulator and pulse width modulator operative upon the high voltage transformer to control high voltage in response to changes of CRT beam current loading imposed thereon.

摘要： An image display system includes a first projector and a second projector, and makes the first projector and the second projector operate in cooperation with each other to form a single projection image on a common screen. The first projector and the second projector are connected to each other via a signal line. A master control section of the first projector transmits a control signal to a subordinate control section of the second projector. The subordinate control section of the second projector controls a projection section of the second projector based on the control signal. Thus, the controllability of the image display system provided with a plurality of projectors is enhanced.

摘要： A cathode ray tube high-voltage supply system is of the type in which sawtooth-shaped pulses are developed in a first transformer winding in order to produce a scanning waveform in a deflection yoke on the tube. So-called fly-back energy, developed as a result of magnetic field collapse in the yoke during retrace, is utilized, in turn, to produce high-voltage output pulses in another winding to which a load is coupled that requires a broad, generally-square pulse shape. The first winding is wound upon a first ferromagnetic core that defines a non-saturating magnetic circuit. The other winding is wound upon a second ferromagnetic core which, together with a portion of the first core, defines a second magnetic circuit that saturates in operation. A capacitor included in the load is coupled across the other winding and controls the energy in said second magnetic circuit in such a manner as to supply the load with pulses that are broad and have a generally-square shape.

摘要： A high voltage generating circuit for a television receiver including a flyback transformer having primary and secondary windings which are loosely coupled to achieve substantial operational isolation therebetween. The secondary winding has a diode rectifying circuit coupled thereto for developing the high voltage signal which is applied to the anode of the television receiver. A tertiary winding is provided which is tightly coupled to the secondary winding and which has a capacitor in parallel therewith to form a resonant circuit which is resonant at a frequency somewhat higher than the horizontal sweep frequency applied to the deflection coil of the television receiver.

摘要： A power supply circuit having a piezoelectric voltage transforming device resonant in a preselected one of a plurality of mechanical vibrational modes for transforming low primary alternating voltages to high secondary alternating voltages whereby the preselected mode is an optimum resonant mode having a range of operating frequencies over which the device resonates with changes in input impedance for the device. The primary alternating voltage is returned at a first operating frequency through a positive feedback circuit loop and an amplifier driver circuit to lock in the particular operating frequency of the device. The positive feedback loop has frequency selective means therein for determining the selection of the optimum resonant mode. Operating frequency can be altered through phase control of the primary feedback voltage within the positive loop, which change of operating frequency alters input impedance and hence the level of voltage transformation through the piezoelectric device.

摘要： A first transformer is coupled to a deflection yoke and coupled to a derived secondary voltage source for driving a load, for example, for generating an ultor voltage. An on/off switch is responsive to an on/off signal. A second transformer has a primary winding coupled to the switch and coupled to a voltage source and has a secondary winding coupled to the first transformer. A first sampling circuit generates a first feedback signal indicative of current flowing from the secondary winding to the first transformer. A first safety circuit responsive to the first feedback signal controls the effect of the on/off signal on the switch when the current flowing from the secondary winding to the first transformer exceeds a threshold, by limiting the on time of the switch to limit the peak value of the current. A second sampling circuit generates a second feedback signal indicative of the ultor voltage. A second safety circuit responsive to the second feedback signal controls the effect of the on/off signal on the switch when the ultor voltage exceeds a threshold, for example due to picture tube internal arcing, by interrupting propagation of the on/off signal to block operation of the switch. A third sampling circuit senses current conducted by the switch and generates a third feedback signal. One of the first and second safety circuits is also responsive to the third feedback signal. The switch, the transformer and the deflection yoke can be coupled in a Wessel configuration.
