Abstract: PURPOSE:To improve or make constant the rigidity of the connection and realize a lightweight of an envelope, by arranging a space near the connection in the envelope of a cathode-ray tube. CONSTITUTION:An envelope 1 of a cathode-ray tube consists of the first envelope 4 including a face plate 2 projecting in the axial direction with an almost spherical form and a skirt 3 extending almost parallel to the tube axis in the direction opposite to the projection of the plate 2 from the periphery of the plate 2, a funnel 5 connected to the connection C of the end of the skirt 3, and a neck 6 at the extension of the funnel 5. The funnel 5 and the neck 6 are integrated to be the second envelope 7. Near the said connection C, a space 8 is formed. Therefore, the rigidity of the cathode-ray tube envelope 1 is improved, and by making the rigidity constant, the lightweight of the envelope 1 can be realized.

Abstract: PURPOSE:To reduce the electric field discharge current, by furnishing a coating layer to control the electric field discharge, at least at a part of at least one or more electrodes of plural electrodes. CONSTITUTION:This electron gun 1 is composed of a cathode 3 generating electron beams to be radiated and struck to a phoshor layer heated by a heater 2, and plural electrodes furnished one by opposing to the cathode 3, including the first grid 4, the second grid 5, the third grid 6, the fourth grid 7, the fifth grid 8, and a convergence electrode 9. Over the surface of the second grid 5 and the fifth grid 8, ceramic layers 10 mainly of SiO2 are formed. The ceramic layers 10 make difficult to concentrate the electric field and reduce the opportunity of electric field discharge, by burying the projections over the surfaces of electron gun parts and contaminated particles in the ceramic layer, or by weakening the sharp projections of the contaminated particles by the ceramic layer. Furthermore, by applying the ceramic layer of a conductivity much smaller than that of metals over the surface of the electron gun electrodes, the charge transmitting speed to the electric field discharge surface is liable to reach to the limit. Therefore, the electric field discharge current can be reduced.

Abstract: PURPOSE:To improve resolution, by forming a large-sized cathode-ray tube having many small electron-gun parts and both a screen part and mask part unitedly composed corresponding to them, with the arrangement of each small electron-gun part being regulated in a specific relation. CONSTITUTION:At the rear part of a surrounding device 2 having a screen composed of split-display fluorescent screens 101-115, many neck parts are mounted, with a small electron-gun part 4 being housed in each of them, and a shadow mask 5 is arranged in a continuous shape, to compose a color cathode- ray tube. When the distance between neighboring electron-guns, GS, the distance between mutual electron beams, SG, the pitch of a shadow mask 5, PH, the edge distance between shadow mask effective opening parts, d, integer values, m,n are respectively defined, a setting-up equation is made to be GS=(m.SG/ PH){n-1)PH+d}. Therefore, with defects being removed at each area part jointed with the screen, a large-sized cathode-ray tube of good quality and high resolution can be obtained.

Abstract: PURPOSE:To acquire an electron tube of an excellent emission life property, such as a color cathode-ray tube for example, by furnishing an activated silicon oxide layer inside the outer container. CONSTITUTION:This electron tube is an electron tube with a cathode to generate electrons inside the air-exhausted outer container, in which an activated silicon oxide layer is formed inside the outer container. The activated silicon oxide means the silicon oxide to absorb remaining gas in the outer container, especially harmful gas to the emission from the cathode. This can be made from a silicon compound salt, and is considered to cover the exhausted outer container wall, and some parts of the surface of various electrodes, as a porous layer with numerous pores. The amount of the activated silicon oxide is preferable to be 1mg to 50mg per l of the outer container volume. If it is less than 1mg, it will scarcely affect the extension of emission life of the cathode, and if more than 50mg, the level of the effect is saturated.

Abstract: PURPOSE:To curtail manufacturing process and realize reduction of energy cost by eliminating unwanted heating and cooling of panels or valves through execution of baking, sealing and exhausting processes within the same furnace. CONSTITUTION:A panel 24 having a phosphor screen, an organic material film, and a metal vacuum-deposited film deposited on its internal surface and a funnel 28 having an electron gun 26 loaded at its neck 25 are disposed within a furnace 30 in such a manner that the neck 25 is located outside the furnace 30, while the sealing part is coated with a sealing agent 29 and the sealing parts are separated by the specified distance. An organic material remaining on the internal surface of panel 24 is dispersed and simultaneously the sealing agent 29 is melted through the first heating process and thereby the sealing parts of both the panel 24 and funnel 28 are brought in contact with each other via the sealing agent 29. Next, the panel 24 and funnel 28 are sealed together by controlling the temperature within the furnace 30, forming a sealed valve. Before the sealed valve temperature drops to the room temperature, the furnace temperature is raised again before it drops to a room temperature. During this temperature cycle, the inside of sealed valve is exhausted through an exhausting tube 272 of the neck 24. During this exhaustion, the furnace temperature is lowered and when exhaustion is completed, the exhausting tube 272 is sealed.
