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 secure such a high resolution cathode-ray tube that is less in electrostriction and lens aberration, by letting a terminal leading-out conductor for a conductive film electrode take a bypassing structure which makes it return to the side of an inner circumferential surface, after once going out onto an outer circumferential surface of a glass bulb. CONSTITUTION:A terminal leading-out conductor for an electrode 18 consisting of a conductive film is formed of a first conductor 29 piercing through airtightly from an end part of the electrode and coming onto an outer circumferential surface of the glass bulb, a second conductor part 31 additionally installed on the outer circumferential surface of the glass bulb, a third conductor part 30 piercing through the glass bulb and coming onto an inner circumferential surface of the glass bulb and a fourth conductor part 15 coming to a conductive pin 32 from the third conductor part. Even if another conductive film electrode exists between the electrode consisting of the conductive film and a stem, terminal leading-out to stem conductive pins 27 and 32 can be done by the terminal leading-out conductor bypassing the said electrode, so that turbulence in a lens electric field, an insulation drop between electrodes and an increase in electrostatic capacity caused by what the said conductor traverses other electrodes are all restrainable.

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.

Abstract: PURPOSE:To enable various kinds of glass material to be used as a transparent disk plate and to produce thermal and mechanical stability of the disk plate so as to achieve its airtightness by packing the soft metal indium into a thin hole of the transparent disk plate. CONSTITUTION:A transparent disk plate 7 made of glass has a thin hole 8 extending from the surface 7a to the other surface 7b. The inner surface of the thin hole 8 is provided with a conductive film 9 extending from the surface 7a. After this process, a part of a small indium sphere 10 is pressed into the thin hole 8 from the other surface 7b of the transparent disk plate 7 to make the sphere 10 in contact with the conductive film 9. Then, the indium 10b remaining above the other surface 7b is shaped into a semispherical shape to make a target terminal led outside the tube. Therefore, there is no possibility for the transparent conductive film 11 and photoconductive film 12 formed over the inner surface of the tube to be stained or damaged. Since indium is packed into the thin hole 8 of the transparent disk plate 7, various kinds of glass material can be used as e disk plate 7.

Abstract: PURPOSE:To reduce the applied voltage to an electrode and keep the electric insulation property at each section satisfactorily by forming a cylindrical electrode smaller than a combination electrode in diameter and locating many lead wire sections from the combination electrode at the outside of the cylindrical electrode. CONSTITUTION:One end opening section of a cylindrical glass bulb 3 is hermetically sealed via an indium ring 4 to a face panel 2 provided with a photoconductive target electrode 1 on its inner face. Cylindrical grid electrodes 15, 16 made of a conductive film are provided on the inner periphery of the bulb 3, and the electrode 15 is divided into four arrow-shaped pattern regions like a deflection type deflecting electrode as a combined focusing electrode and horizontal/vertical deflecting electrode. Lead wire sections 17 from these four regions respectively are guided to the outside terminal through the overlap section of the bulbs 3, 5 around the outside of a grid 12. As a result, the electric insulation property of each section is kept satisfactorily.

Abstract: PURPOSE:To fix a mesh electrode highly accurately and to lead out the power supply terminal by providing a step in the innercircumferential face of tubular glass bulb to be butted through an indium ring for air-tight sealing against the front face glass board associated with a target electrode. CONSTITUTION:A tubular glass bulb 5 butted through an indium ring 4 for air-tight sealing against a front face glass board 3 associated with a target electrode on the inner face is provided with an annular step 6 in the inner tube area slightly set back from the open endface contacting against the indium ring 4. Since the mesh electrode 7 is engaged while bearing the outercircumferential edge onto the step 6, in the air-tight sealing stage through the indium ring 4, the pressing pressure will never function directly onto the mesh electrode thus to protect the mesh electrode from inclination or deformation. Consequently, it can be fixed highly accurately while the power supply terminal can be led out to the outside.

Abstract: PURPOSE:To obtain a pickup tube with a high S/N characteristic which is capable of leading the target electrode terminal to the outside of tube by utilizing bonding agent or frit glass for sealing agent and providing conductive film part extended to the outside of tube through the gap between the front glass plate and sealing agent film to the transparent conductive film. CONSTITUTION:A front glass plate 4 having a cylindrical glass bulb 1 at the internal circumferential surface of conductive film 2 and being sealed in air tight through a sealing agent layer 3 at the one opening end is provided with a target electrode consisting of transparent conductive film 5 and high heat resistance photo conductive film 6. Regarding the transparent conductive film 5, the outer part 7a of belt-shaped conductive film 7 extended to the outside of tube through the gap between front glass plate 4 and sealing agent layer 3 is formed as a target electrode terminal, while the outer part 8a of beat- shaped conductive film 8 extended is formed as the terminal of the electrode by conductive film 2 and mesh electrode 9. The sealing agent layer 3 is formed by a low melting point frit glass which forms the air-tight sealing part between the glass bulb 1 and front glass plate 4, thereby eliminating disturbance of electric field.
