摘要： An electron gun as for a cathode ray tube includes a plurality of electrodes biased at different potentials to electrostatically shape and focus the one or more electron beams produced thereby. A dynamic focus grid is driven by a substantial ac voltage signal at the horizontal line rate, which signal is undesirably coupled through parasitic capacitance to an intermediate grid located between the dynamic focus grid and the gun anode. A resistive biasing network includes a high value resistance to divide the anode potential to develop bias potential for the intermediate grid and a capacitance to ac couple the intermediate grid to ground potential. The resistance is formed in a single layer ceramic circuit and the capacitance is formed on the single layer ceramic circuit or on the tube neck. The ceramic circuit may be located in the tube neck on or with the electron gun.

摘要： An ion source including an electron generating chamber and an ionization chamber adjacent the electron generating chamber and having an opening therebetween. The ionization chamber has a gas inlet opening and the electron generating chamber has a outlet. The gas inlet opening, the outlet and the opening between the two chambers are all on a common axis. The electron generating chamber has therein a cathode filament which extends completely around the axis and generates electrons, electrodes for directing the electrons transversely toward the axis and a deflection electrode for deflecting the electron flow along the axis and into the ionization chamber. An accelerator plate is adjacent the outlet and is adapted to attract ions generated in the ionization chamber along the axis and through the outlet.

摘要： A cathode ray tube and a plural beam electron gun therefor include a main lens that comprises a tubular focus grid G5 and a conductive coating on the inner surface of the tube neck. The neck coating extends from the region of focus grid G5 towards the faceplate of the cathode ray tube. Preferably, the exit of the focus grid G5 is non-planar and is curved or undulated and focus grid G5 includes an aperture plate intermediate its entrance and exit. The aperture plate preferably has an elliptical center beam opening and connected-semi-elliptical outer-beam openings, to better converge and focus the outer and center electron beams. Also preferably, the focus grid G5 is centrally located in the tube neck and at least partly surrounded by the conductive neck coating.

摘要： A piezoelectric body has a transducer on one surface. The transducer includes an electrically insulating body on the piezoelectric body; the electrically insulating body has a surface relief pattern on a surface which is opposite the piezoelectric body. An electrically conductive layer is on the electrically insulating body on the surface having the relief pattern thereon.The transducer can be formed by means of a master body. A surface of the master body, having a relief pattern thereon, is pressed against the electrically insulating body to form a relief pattern on the electrically insulating body. The electrically conductive layer is then formed on the electrically insulating body on the surface having the relief pattern thereon.

摘要： A projection tube has a phosphor-coated faceplate at one end of a vacuum envelope and a plural-beam providing electron lens structure at the opposite end thereof. The electron lens structure includes four electrodes having axially-aligned apertures defining parallel channels for the plural electron beams to pass through to be focused and converged onto a small spot on the faceplate. The first and second electrodes of the electron lens structure shape the electron beams and the third and fourth electrodes thereof converge and focus the electron beams toward the same location on the faceplate. The potential applied to the fourth electrode is at or close to the potential at the phosphor, and is substantially higher than the potential applied to the third electrode. The lens structures of the third and fourth electrodes may each include an inner electron lens structure and an outer electron lens structure. The lens structure of the invention provides a projection tube having greater brightness and/or smaller spot size than is conventionally available.
