Abstract: PURPOSE:To eliminate the fluctuation of converging state of an electron beam caused by the presence of adsorption gas by providing a voltage generating circuit to boost the deflectron electrode potential only during the blanking period. CONSTITUTION:A blanking voltage Vb' is applied to a 1st grid 2 and a blanking voltage Vb'' is applied to a 4th grid 7 respectively. The blanking voltage Vb'' given to the 4th grid 7 of the deflectron electrode is used to boost the potential of the 4th grid at the blanking period by a hundred and several tens volt or above, and the blanking voltage Vb' given to a 1st grid is used to increase the quantity of the electron beam emitted from an electron gun during the blanking period to a prescribed value or above. Thus, the fluctuation in the focusing state of the electron beam through the presence of the adsorption gas to the part of the deflectron electrode is eliminated to increase the stability of the image pickup tube.

Abstract: PURPOSE:To hold down the occurrence of pseudo signals, by enclosing an electron beam passage which extends from an electron gun via a deflecting electric field to the effective scan range of a target electrode, and projecting a conductive tubular body for the tip portion of the electron gun wherein the tubular body interrupts a reflection beam passage which extends from the electron gun electrode to the outside of the effective scan range of the target electrode. CONSTITUTION:A cylindrically shaped conductive tubular body 12 is provided coaxially for the tip portion of an electron gun 1. The tubular body 12 encloses an electron beam passage without entering into the same passage wherein the passage extends from the electron gun 1 to the effective scan range A of a target electrode 6 via a deflecting electric field owing to a deflection type horizontally and vertically deflecting electrode 4, and has a sufficient diameter and length for interrupting a reflection beam passage which extends from the electron gun electrode to the outside of the effective scan range of the target electrode 6. The reflection beam passage 11' extends to the outside of the scan range which comes into contact with the most outer circumference of the effective scan range A of a target electrode 6, and this reflection beam passage 11' is interrupted by the tip portion of the tubular body 12. Thus, a reflection beam 11 comes into collision with the inner surface of the tubular body 12, here secondary reflection beams 11a and 11b are newly generated.

Abstract: PURPOSE:To check generation of an excessive pseudo-signal even when a return beam flows into a getter vacuum evaporation film by connecting a conductive getter vacuum evaporation film with a deflection electrode or a terminal to which the prescribed potential is to be given for being held in proper potential. CONSTITUTION:One of four conductive films 4 for deflection electrodes is provided with the extended part 16 projecting toward a getter vaccum evaporation film 15 while forming the getter vacuum evaporation film 15 partly overlapping said extended part 16 by getter flash. And generally voltage of about 300+ or -60V is impressed on the conductive film 4 for a deflection electrode so that the getter vacuum evaporation film 15 is held about in said potential. Thereby, the greater part of the return beam going to the side of the getter vacuum evaporation film 15 is absorbed by the getter vacuum evaporation film 15 while reducing a reflection beam and suppressing generation of a pseudo-signal.

Abstract: PURPOSE:To provide a gas discharge type display device of simple structure, which is equipped with a long lifetime, high brightness, and low power consumption and whose power supply is embodied small and light and is manufacturable at a low cost. CONSTITUTION:Address electrodes 2, dielectric substance layer 3, and cathodes 4 are laid one over another on a photo-transmissive base board of glass 1, and anodes 6 having resistor 6a group 6a and electrode 6b group and an insulative layer 7 are furnished one over the other on an insulative base board 5, wherein the anodes 6 are intersectingly arranged opposing to the address electrodes 2 while the dielectric substance layer 3 and insulative layer 7 are interposed in between. The driving method for this display device consists of impressing a scan pulse can the anodes 6, impressing a write pulse on the address electrode 2 mating with the discharge cell 9 in which a write is to be made so that a write discharge takes place, impressing a retention voltage on the cathodes 4, continuing the retention discharge condition during the period the retention voltage is being impressed, and generating a light emission from the discharge cell 9 into which write is made. In the same manner, scan is made for the group of anodes, and thereby light emissions are performed from all discharge cells 9 into which write is made to generate display of one image.

Abstract: PURPOSE:To simplify the panel structure of a display apparatus, lessen the electric power consumption, and extend the life by forming discharge holes in a second dielectric layer and setting address electrodes and anodes face to face as to accumulate electric charge on the surface of the second dielectric layer existing at least in the periphery of the discharge holes. CONSTITUTION:To display the same images in a matrix-type panel, positive potential is applied to anodes 4 corresponding to the discharge cells 9 in the first row in which the images are to be displayed and negative potential applied to address electrodes 2 in the first row. As a result, writing discharge occurs and positive charge is accumulated on the surface of a second dielectric layer 5 and writing discharge automatically stops and at the same time the display content of the first row is saved in the surface. In this case, discharge holes 10 are so formed as to expose at least a part of anode group 4 to the layer 5 and the electrodes 2 and the anodes 4 are set face to face as to accumulate the charge on the surface of the layer 5 existing at least in the peripheries of the holes 10. As a result, charge is accumulated on the layer 5 and writing discharge stops automatically and discharge current can be controlled, so that the panel structure can be simplified and electric power consumption can be lowered and a long operational life can be provided.

Abstract: PURPOSE:To increase the output of carrier signals by making the width of the colorless transparent stripes of a color filter smaller than the width of the colored stripes of the color filter. CONSTITUTION:The width (d ) of the colorless transparent stripes (w1) of the first filter is smaller than the width (dcy) of the cyanogen stripes (Cy) of the first filter. The width (d ) of the colorless transparent stripes (w2) of the second filter is smaller than the width (dye) of the yellow stripes (ye) of the second filter. As a result, decreases in the DC component are greater than decreases in the AC component. Consequently, it is possible to achieve an increased modulation factor.

Abstract: PURPOSE:To reduce false signals and improve the efficiency and uniformity of a bias light by providing a ring-like member with its inner diameter nearly equal to the outer diameter of a cylindrical electrode and its outer diameter nearly equal to the inner diameter of a glass tube body on the outer periphery of the final cylindrical electrode of an electron gun. CONSTITUTION:A ring-like member 31 with its inner diameter nearly equal to the outer diameter of a cylindrical electrode 3 and its outer diameter nearly equal to the inner diameter of a glass tube body 1 is provided on the outer periphery of the cylindrical electrode 3. A return beam 13 is returned to the cylindrical electrode 3 or ring-like member 31. At this time, a contact spring 15 and a spot welded point 16 portion generated when the electrode of an electron gun 2 is assembled which generate many reflection beams are covered by a ring- like member 31. Therefore, reflection beams 14 are remarkably reduced, and the false signal image is so much improved that the false signal image of the cylindrical electrode 3 and the false signal image on a scan screen are barely visible. Thereby, the false signal can be remarkably reduced.
