Abstract:
A light illumination portion illuminates light to a sample surface. A probe has a tip which is smaller than the wavelength of light illuminated by the light illumination portion, the tip is provided near the sample surface to which the light is illuminated, and scatters the light. A light detection portion detects light scattered by the probe. A scanning portion relatively scans the sample and the tip of the probe. A near field optical microscope has a constitution such that plasmon resonance is generated during scattering by the probe. Another light illumination portion illuminates light to the surface of a sample. Another probe has a tip provided near to the sample, and the tip of the probe generates scattered light originating in light illuminated by the light illumination portion. Another light detection portion detects light scattered by the probe. An illumination light modulation portion modulates the wavelength of the light illuminated by the light illumination portion at a predetermined frequency. An extraction portion extracts components at the predetermined frequency of the illumination light modulation portion from an output of the light detection portion.
Abstract:
A panel structure for a Braun tube is described satisfying the following conditions: Rdo/(USDd×1.767)≧35 and 0.7≦(MMLHd/OAH)≦0.9, wherein Rdo denotes a radius of curvature of a panel in a cathode ray tube, USDd denotes a length of the effective surface part in a diagonal direction, MMLHd denotes a height from the seal edge line to the mold match line, and OAH denotes a total height of a panel, thereby suppressing implosion that occurs during or after fabrication of a Braun panel and securing an implosion proof characteristic.

A shrinkage band for a CRT including: a panel forming a display screen; and a shrinkage band having a predetermined width combined to cover the outer circumferential surface of the side portion of the panel in a state of satisfying an inequality of 0.95≦Fa/Fb≦1.39 on the assumption that an engagement tensile force of the front side of the panel is Fa and that of the opposite side of the front side of the panel is Fb on the basis of the line extended in the horizontal direction of the panel from the center of the curved portion of the corner of the inner side of the flat panel. With the construction, the explosion characteristics of the flat panel can be highly improved along with an effectiveness that a reliability can be enhanced and a stability in use can be obtained.

A cathode ray tube with a central axis includes a panel with an inner phosphor screen, and a funnel connected to the panel. The funnel has a cone portion with a neck sealing side, and a body portion extended from the cone portion to the panel. A deflection yoke is externally mounted around the funnel. A neck is connected to the neck sealing side of the cone portion. An electron gun is mounted within the neck. The funnel is structured to satisfy the following condition: −0.145
Abstract:
In a color cathode ray tube, inner lead pin segments which extend inside the neck of a funnel constituting an vacuum envelope, outer lead pin segments which are led out of the neck and interconnecting wires which respectively connect both lead pin segments together are provided in a stem for sealing the end portion of the neck. The inner lead pin segments are arranged along a first circumference and are supported by respective projections protruding from the stem. The outer lead pin segments are arranged along a second circumference having a larger diameter than that of the first circumference. The inner lead pin segments are connected to the respective outer lead pin segments by the respective interconnecting wires which are bent in the stem and the respective projections.
Abstract:
A color cathode ray tube apparatus is provided to reduce the amount of deflection power required, this apparatus having a panel part, on the inside surface of which is formed a phosphor film that emits three primary colors, a funnel part that has its expanded aperture joined to the panel part and a funnel-shaped part, a neck part in which is housed an electron gun structure, and which is joined to the reduced-diameter &phgr; a aperture of the funnel part, and a deflection yoke that is disposed between the funnel part and the neck part, the neck part being formed by a main part that houses the electron gun structure and a reduced-diameter part to which are attached the deflection yokes. The funnel part has a quadrangular pyramid shape at the end that is joined to the neck part, and this can also be used for attachment of the deflection yoke.
Abstract:
A dual-gun, single neck CRT focuses two beams, with significantly differing energies, onto a secondary emission target while maintaining compatibility with a standard fourteen-rotation stem and achieving FTU in excess of 95%. A pair of Einzel guns (write and erase) are mounted in parallel and aligned in the vertical direction rather than the horizontal inside the CRT. The write and erase guns are configured to share a common second accelerator electrode, a common final accelerator electrode, mounting beads and a magnetic deflection yoke. The guns' focus voltages are independently adjusted so that both the write and erase beams have the same focal length.
Abstract:
A color cathode ray tube having a panel to which a fluorescent layer is applied, a slim neck portion with an electron gun, a funnel joined to the panel, and a stem with the electron gun sealed to the neck portion, wherein if an inner diameter of the neck portion and an outer diameter of the stem equal a and f, respectively, an interval between the neck portion's inner diameter and the stem's outer circumference meets the condition of 0.2≦(a−f)/2≦3.0, and the neck portion's outer diameter equals 23.0 mm to 28.5 mm.
Abstract:
The glass funnel for a cathode ray tube includes a cylindrical funnel neck (2); a funnel body (4) having successive transverse cross-sections that change over from a substantially circular shape to a substantially rectangular shape with cross-sectional areas growing continuously in a direction moving away from the funnel neck and a parabolic region (3) arranged between the funnel neck and the funnel body and having respective connecting sections to the funnel neck and the funnel body having corresponding substantially circular cross-sections. The parabolic region (3) has at least one part with a substantially rectangular cross-section and the at least one part is located between the respective connecting sections to the funnel neck and the funnel body. When a cathode ray tube is made from the glass funnel the electron gun is located in the funnel neck and the deflecting coil is arranged around to the parabolic section so that it is substantially closer than in the prior art cathode ray tube. The glass funnel described herein thus provides energy savings and a more precise electron beam guidance than the corresponding prior art glass funnel, when it is incorporated in a cathode ray tube.

A glass envelope for a cathode ray tube (10) and a method of production. The envelope comprises (12) a panel member having a thickness (t) that is defined by an equation which involves net tensile stress; wherein the panel having a net tensile stress not exceeding 1150 psi, having a surface compression induced during panel manufacture, and having an implosion protection band (30) shrink-fitted around a skirt (20) on the panel that augments surface compression in the panel (12), whereby the panel thickness is substantially less than that of a corresponding untreated tube envelope.
