摘要： A deflection yoke and a color cathode ray tube using the same therein and adapted for exact correction of misconvergence caused when horizontal positional deviations are induced between electron beams and a vertical deflection magnetic field. In the deflection yoke, two magnetic coil pairs are positioned opposite to each other horizontally in such a manner as to interpose the neck of a cathode ray tube therebetween. The first coil of the first coil pair is connected in series or parallel to the fourth coil of the second coil pair. The second coil of the first coil pair is connected in series or parallel to the third coil of the second coil pair. The coils thus connected are further connected in series to a vertical deflection coil. In this structure, the first and second electric coil pairs are so connected as to generate magnetic fields in mutually reverse directions. The two electric coil pairs in combination with a variable resistor constitute a bridge circuit. And the above misconvergence can be corrected by controlling the variable resistor.

摘要： The invention is intended to enable the easy measurement of the amount of color purity at each of many measured points. An adjusting coil (9) is provided at a neck portion of a color cathode ray tube (1). Also, a color image pickup means (4) for photographing the screen of the color cathode ray tube (1) is provided. A monochrome signal of any one of red, green, and blue colors is input to this color cathode ray tube (1). Thereafter, while varying the electric current made to flow through the adjusting coil (9), the image pickup signal obtained by the color pickup means (4) is decomposed into red, green, and blue color signal components; and the intensity of each of them is measured. Then, using the values of the electric currents that are supplied to the coil adjusting (9) and the location distances between the luminous regions of the red, green, and blue colors on the color cathode ray tube (1), there is determined the following: the amount of movement of the relevant electron beam with respect to the unit value of electric current for the adjusting coil (9). Thereby, it is arranged that the amount of color purity at the measured point is obtained according to the amount of movement of the relevant electron beam with respect to the unit value of electric current for the adjusting coil (9).

摘要： A landing correction coil is provided at the rear of a horizontal deflection coil of a deflection yoke or at a position where it is closely coupled with the horizontal deflection coil. The landing correction coil is fixed so as to generate a magnetic field perpendicular to the axis of a CRT. Moreover, the landing correction coil is connected so that a current flowing in a horizontal deflection coil may flow in the landing correction coil. Furthermore, the landing correction coil is connected to an adjustment coil for adjusting the current flowing therein. A varying means is provided in the adjustment coil and the polarity and amplitude of the current flowing in the landing correction coil is adjusted by the varying means. This causes the magnetic field distribution for scanning an electron beam of a CRT to be changed and enables a landing characteristic to be adjusted electrically.

The display apparatus includes a dynamic focusing circuit for producing the dynamic focusing voltage by superimposing, on a dc voltage supplied from outside, an ac voltage which has a waveform varying in synchronization with horizontal and vertical deflections of an electron beam flowing to a fluorescent screen on the anode. The display apparatus further includes a compensator for lowering the dc voltage supplied to the dynamic focusing circuit by a predetermined value while a brightness signal indicative of brightness of a screen of the CRT exceeds a threshold value.

摘要： A current variable inductor having closed loop characteristics and a horizontal linearity compensation circuit. The current variable inductor having the closed loop characteristics is constructed with the legs of the first E-shaped core and the legs of the second E-shaped core extend toward each other, an I-shaped core is arranged between the first E-shaped core and the second E-shaped core such that the I-shaped core is in contact with the first E-shaped core, and the I-shaped core is spaced apart from the second E-shaped core. A primary coil is wound around a center leg of the first E-shaped core and a secondary coil is wound around a center leg of the second E-shaped core. A magnetic flux generated from the primary coil is cut due to the magnetic resistance characteristics of the I-shaped core to vary the inductance of the secondary coil, to thereby form enclosed loops of magnetic flux inside the first and second E-shaped cores, respectively.

摘要： The invention relates to a method and a device for reducing an electric field produced by display devices equipped with cathode ray tubes, in their surroundings. According to the invention, a part of a spectrum (ff), caused by a picture content, the level of which is separately adjusted, is discriminated from an interference voltage frequency spectrum (fs), produced by the display terminal and caused by deflection signals (fv, fh). Spurious pulses, significant for the generation of the electric field, are connected to a compensation circuit, wherein they are summed and supplied to a common emitter. The directions of the pulses are determined so that the electric field produced by the emitter reverses the field produced by the display device.
