Abstract: In a planar type display device, deterioration of the picture quality caused by distortion of laminated electrodes due to temperature rise in use is prevented by laminating the electrodes having such a structure that each electrode plate is free from expansion and contract by thermal expansion. Securing means spacers 23 thicker slightly than electrode plates are inserted in holes of the electrode plates 21a to 21e, securing means pin 24 is passed therethrough holding electrode plate spacers 22 therebetween, forming laminated electrode group 5. Since the respective electrode plates have slight gaps in a thickness direction and the electrode plates are free from expansion and contraction and do not distorted at the time of thermal expansion.

Abstract: An electrode assembly for display apparatus is disclosed. A plurality of electrodes of different rigidities are provided between a cathode and a fluorescent material through coupling spacers. Plural kinds of coupling spacers are prepared in each of which the materials of a substrate metal, an insulating layer and a glass frit are different from each other and the proportional thicknesses of these components are varied to the extent that the intervals between the electrodes of different rigidities are not changed are prepared. An electrode block is completed by arranging the electrodes and the spacers such as to cancel the rotating moment around the neutral axis of the electrode block and joining them by means of calcination. The assembling accuracy of the electrode block is heightened very advantageously for positional accuracy with respect to the fluorescent screen.

Abstract: In some embodiments, an electrical device can include a body having a shape that extends along a longitudinal direction, and a set of electrodes implemented on the body at different locations along the longitudinal direction and configured to allow the electrical device to be positioned and mounted to a surface. The set of electrodes can include first and second electrodes configured to provide first and second engagements with the surface, respectively, and to allow a settling motion when the electrical device is positioned on the surface. The set of electrodes can further include a selected electrode having a side configured to allow the settling motion and an engagement portion configured to stop the settling motion and thereby provide a third engagement with the surface.

Abstract: The present invention relates to an electron gun cathode mount adapted at one end to secure a thermionic cathode and at the other end to be connected to an attachment member, wherein the electron gun cathode mount is structured so as to be capable of, when in use, reducing heat transfer from the thermionic cathode to the attachment member, and the material forming the electron gun cathode mount has a thermal conductivity of less than 10 Wm−1K−1 at the operating temperature of the thermionic cathode in a direction from the thermionic cathode to the attachment member. The present invention also relates to an electron gun assembly having the electron gun cathode mount installed therein.

Abstract: A photoelectric-surface electron source includes: a glass substrate that receives laser light from a substrate light-receiving surface including microlenses and that focuses the laser light toward a substrate main surface located on the opposite side from the substrate light-receiving surface; a photoelectric surface that is provided to the substrate main surface, and that receives the focused laser light and emits photoelectrons; and an extraction electrode that is fixed to the substrate main surface and that extracts the photoelectrons from the photoelectric surface. The extraction electrode is disposed away from the photoelectric surface along the normal direction of the substrate main surface and has: an electrode part in which electrode holes for allowing the photoelectrons to pass therethrough are provided; and a frame part that is fixed to a region surrounding the photoelectric surface in the substrate main surface.
