摘要： PURPOSE:To provide a focusing device capable of accurately and easily focusing in a short time by detecting and correcting even focus deviation in an oblique direction due to deflection instrinsic to a CRT. CONSTITUTION:Horizontal and vertical waveforms for focus correction are generated from horizontal and vertical deflection pulses in a waveform generation circuit 11, superimposed on a high DC bias voltage generated in a flyback transformer 12 and added to the first focusing electrode 14 and second focusing electrode 15 of the CRT 13 and the spot diameter of an electronic beam is controlled. Since a light emitting material on the inner side of an applied member 16 emits light when the controlled electronic beam scans on the member 15 applied with the light emitting material, the light emitting time (t) of the light emitting material is detected in a light emission detection means 17, the voltage amplitude of the horizontal and vertical waveforms for the focus correction is controlled so as to minimize the light emitting time in a waveform control circuit 18 and the optimum focus is adjusted.

摘要： PURPOSE:To provide a clamping circuit capable of stably clamping a black level to a reference level even for video signals in which pulse noise is mixed concerning the clamping circuit of the video signals. CONSTITUTION:A difference between an input signal level and a feedback signal level is obtained by a subtracting circuit 1 and the output signals of the subtracting circuit 1 are sampled by clamp pulses for the prescribed period of time at cascade connected median circuits 2 and 3. The sampled signals are converted to a median value by plural median filters and a subtractor 4 subtracts a clamp level from the median value and outputs a control value. A memory circuit 5 holds the previous control value until such time as sampling is performed by the next clamp pulse and the next control value is obtained and then stably clamps the black level of the video signals to the reference level.

摘要： PURPOSE:To prevent production of mis-convergence and to improve the picture quality by differentiating the intensity of a magnetic field fed between a couple of pole pieces through a 1st ferrite core form the intensity of the same magnetic field through a 2nd ferrite core. CONSTITUTION:A dynamic convergence means in use consists of 1st and 2nd ferrite cores on which coils with different number of turns are wound. For example, the number of turns of a couple of coils 12a, 12b wound on the 1st ferrite core 10 is 110.5 respectively and the number of turns of a couple of coils 13a, 13b wound on the 2nd ferrite core 11 is 94.5 respectively. Thus, a deviation in 0.23mm at the left end on a horizontal axis having been caused in a conventional structure where number of turns of all the coils 12a, 12b, 13a, 13b is selected to be 102.5 equally is decreased to 0.10mm by providing a difference from the number of turns in this way. Moreover, a deviation in 0.08mm at the right end on the horizontal axis is reduced to 0.0mm.

摘要： PURPOSE: To accurately correct the phase delay of parabolic signals for correction in horizontal and vertical directions in an image display device for which a deflection frequency is changed. CONSTITUTION: When a horizontal deflection pulse is supplied, a phase controller 21 changes the phase and outputs it to a horizontal correction waveform generation circuit 12. Horizontal parabolic signals generated in the horizontal correction waveform generation circuit 12 are voltage amplified in a horizontal amplification part 13 and a booster 14. Also, the vertical parabolic signals of a vertical correction waveform generation circuit 16 and the horizontal parabolic signals are superimposed on the secondary side of the booster 14 and outputted to a fly-back transformer. At the time, a high-pass filter 19 extracts the horizontal parabolic signals from output parabolic signals and supplies them to a comparison amplifier 20 and the comparison amplifier 20 detects the delay amount of the parabolic signals by the booster 14 or the like. The phase controller 21 controls the phase so as to make a phase difference with the horizontal deflection pulse small.
