摘要：本発明は、インデックス型の陰極線管（１）に係る。トラッキング構造体からのトラッキング素子（１６、１８）は、好適には、スクリーン（１０）の内面に設けられる各蛍光体素子（２０）の上方及び下方において蛍光体素子に横付けにされる。トラッキング素子からの応答信号から得られるトラッキング信号は、電子ビーム（７、８、９）を正しい蛍光体素子上に維持するよう用いられる。本発明のインデックス管では、トラッキング線の一部には、空隙（３０、３０'）が設けられる。この空隙は、トラッキング信号に中断をもたらす。この中断は、特に、管の開始段階においてスクリーン上の電子ビームの正確な位置を得るよう用いることが可能である。

摘要： PROBLEM TO BE SOLVED: To eliminate a defect of a prior-art, due to the fact that a distance between a conductor track and an aluminum layer is short a high electrostatic capacity is formed there, and that a time constant of electron for deciding a signal for electron beam control is increased. SOLUTION: A cathode-ray tube is provided, wherein the position of electron beams (7, 8, 9) is decided by the fact that the conductor tracks (12, 13) are arranged between individual fluorescent material strips of segmented fluorescent material layer (11). In order to evade interference to the decision of the position of the electron beams (7, 8, 9), the conductor tracks (12, 13) are installed on an insulation strip (15).

摘要： PROBLEM TO BE SOLVED: To provide an improved cathode-ray tube which is free from the deficiencies of a prior art. SOLUTION: This is a cathode-ray tube in which the positions of electron beams (7, 8, 9) are determine by installing the detecting strips (12, 13) below or between each fluorescent substance strip of the fluorescent substance layer (11). The detecting strips (12, 13) each contain a semiconductor component that amplifies the measured current signals. Thereby, the positions of the electron beams (7, 8, 9) are determined more precisely and the reproducibility is made better.

摘要： PROBLEM TO BE SOLVED: To facilitate timing control for color switching and to reliably conduct color switching with a simple structure. SOLUTION: This fluorescent screen 20 is regularly arranged with carbon stripes 22R, 22G, 22B between R, G, B phosphor stripes 21R, 21G, 21B. Phosphors of the same colors as those of phosphor stripes adjoining on the front side in the moving direction of electron beams are applied on the electron beam incidence side faces of the carbon stripes 22R, 22G, 22B to form invalid luminescence sections 23R, 23G, 23B. The invalid luminescence sections 23R, 23G, 23B function as index stripes.

摘要： PROBLEM TO BE SOLVED: To excellently reduce scanning distortion by a beam index without floating a black level or declining contrast. SOLUTION: A surface sequencing circuit 200 converts the video images of three primary colors to surface sequential signals for which a field frequency is 3n+1 folds (n) is >=1} and a selection circuit 110 multiplexes video images for scanning distortion detection to a free field. An image tube 125 is provided with the light emitting body of the three primary colors on a display surface 126 and provided with the light emitting body for detecting a scanning distortion amount. A color shutter 124 transmits only the light of the light emission spectrums of R, G and B respectively for emitting the light from the display surface 126 and interrupts the light in a distortion detection period. The system of a photoelectric conversion element 123, a distortion detection circuit 112 and an auxiliary deflection control circuit 113 converts the light emitted from the light emitting body to electric signals, detects the scanning distortion amount and controls a deflection circuit based on detection output.

摘要： PROBLEM TO BE SOLVED: To provide a landing measuring apparatus by which precise landing measurement can quickly and easily be carried out and landing adjustment in a manufacture line of television picture tubes is made easy. SOLUTION: When a magnetic field in-Y direction is generated in the periphery of a position to which the electron beam is radiated, the electron beam 14 radiated to a phosphor screen is deflected in-X direction while receiving Lorentz force and the radiation position of the electron beam is slightly shifted in the-X direction. In the case that the extent of the shift becomes high, the electroluminescence intensity of respective phosphor dots is lowered. The electric current to be applied to the coil for generating a magnetic field is changed step by step at prescribed intervals and the electroluminescence intensity obtained in every step is displayed in a bar graph in which the intensity is displayed as the corresponding height of the bar arranged in parallel to the vertical axis and while taking the graph into consideration, correction is carried out. In the measurement mode, the extent of the landing shift from the peak position of the envelope line is computed.
