摘要： A cathode-ray tube includes a glass envelope having a panel with an inner surface formed with a phosphor screen, and a cylindrical neck extending substantially coaxially with a tube axis. An electron gun is arranged in the neck, and a stem is welded to an end of the neck. The stem has a substantially circular disk-like flare made of glass and having an outer peripheral portion welded to the end of the neck, and a plurality of stem pins attached to the flare. The end of the neck and the flare of the stem are welded to each other such that a glass portion of the flare surrounds a glass portion of the end of the neck from outside.

摘要： A vacuum envelope of a cathode-ray tube includes a panel and a funnel section opposed to the panel. The funnel section has two funnels each having a cone section. Each of the funnels is formed by cutting one side portion of a base funnel which is formed by pressing. The two funnels are joined together at sections thereof so as to form the funnel section and also joined to the panel into the vacuum envelope. A neck containing an electron gun is joined to each of the cone sections. A phosphor screen formed on the inner surface has two scanning regions which are divided scanned by electron beams emitted from the electron guns.

摘要： The present invention aims at maintaining the high focusing performance with a low deflection power in a projection tube which is used as a projection type TV receiver or a projector and is operated at a high voltage and with a single-electron-beam high current. A neck outer diameter of a portion on which a deflection yoke is mounted is made smaller than a neck outer diameter of a portion which accommodates an electron gun. A final electrode of the electron gun has a diameter thereof gradually decreased toward a phosphor screen. The maximum anode voltage of the projection tube is set to equal to or more than 25 KV and the maximum beam current is set to equal to or more than 4 mA.
