A cathode sleeve structure for housing a heater. The cathode sleeve structure includes: a case member that is cylindrical and an end thereof is open; a plurality of supporting members that extend radially from vicinities of the end of the case member; and a linkage member that connects the plurality of supporting members. The case member, the plurality of supporting members, and the linkage member are formed as one piece.

The present invention provides an electron gun which includes an electrically non-conductive substrate through which a perforation is provided. The electron gun is characterized in that a cathode-structure supporting member is welded to power-feeding members that are bonded to a stem side of the electrically non-conductive substrate, the cathode-structure supporting member supplying power to a heater included in a cathode structure. Structured as such, it becomes possible to reduce the size of the electron gun in the tube-axis direction, since an additional member for supporting the heater becomes unnecessary. In addition, the cathode-structure supporting member makes the electrically non-conductive substrate to work as a wiring board for supplying voltage to the cathode, thereby realizing a slim cathode-ray tube. Further, the above structure improves accuracy in the assembly process of the electron gun, thereby improving the yield factor.

A cathode-ray tube with high image quality in which electron beams with higher current density than the electron-emitting ability of cathodes are formed and a driving voltage of the cathodes can be decreased. A cathode-ray tube comprises a glass face-panel, a glass funnel connected to the rear part of the face-panel, and an electron gun for emitting electron beams that is contained in a neck portion of the funnel. On the peripheral surface of the funnel, a deflection yoke for deflecting the electron beams emitted from the electron gun is mounted. A phosphor dot for three colors of red, green and blue is applied on the inner surface of the face-panel, thus forming a phosphor screen surface. In the vicinity of the inner surface of the face-panel, a shadow mask is arranged substantially in parallel with the phosphor screen surface. Between the phosphor screen surface of the face-panel and the cathodes in the electron gun, a means for superimposing a plurality of electron beams on the predetermined phosphor dot is provided.

An electronic component includes a laminate including a plurality of insulating layers that are laminated on each other. A capacitor conductor is embedded in the laminate and includes an exposed portion exposed between the insulating layers at a predetermined surface of the laminate. An external electrode is provided on the predetermined surface by direct plating so as to cover the exposed portion. An outer edge of the external electrode is spaced away from the exposed portion by about 0.8 μm or more.

A laminate includes ceramic layers laminated to each other. Internal conductors are embedded in the laminate and include exposed portions that are exposed between the ceramic layers at a lower surface and an upper surface of the laminate. External electrodes are directly plated on the lower surface and the upper surface so as to cover the respective exposed portions. Regions of the lower surface at which the exposed portions are provided are arranged to protrude from the other regions of the lower surface, and regions of the upper surface at which the exposed portions are provided are arranged to protrude from the other regions of the upper surface.

An indirectly heated cathode that can enhance the withstand voltage and the efficiency of radiating heat from a heater to a tubular sleeve, and a cathode ray tube using such a cathode. The indirectly heated cathode comprises a hot cathode emitting electrons at one end, and a tubular sleeve including a high melting point metal and having a heater inside. A thermal absorption layer is formed on the inside face of the tubular sleeve and the thermal absorption layer contains a boron compound.
摘要:
In a method of manufacturing a laminate type electronic component, when a heat treatment is carried out after plating films, which at least partially define external electrodes, are formed by growing plated depositions deposited on exposed ends of a plurality of internal electrodes in a component main body, the presence of the plating films may not only interfere with moisture release, but may also cause blisters or bulge defects in the plating films, while moisture such as a plating solution in the component main body is removed by evaporation. To avoid such problems, cuts to divide exposed ends into multiple sections are formed in extending sections of internal electrodes. Thus, plating films include slits extending in the stacking direction at locations corresponding to positions of the cuts.
