摘要:
A plasma arc tube display is fabricated by arranging a plurality of arc tubes having fluorescent substance layers on the inside and filled with a discharge gas, joining a front substrate and a rear substrate having electrodes to both surfaces of these arranged arc tubes, and interconnecting a plurality of plasma arc tube modules having frames facing the rear substrate with the flexible front substrate interposed therebetween to connect the electrodes installed on the front substrate to each other. Since the plasma arc tube modules can be folded, the plasma arc tube display can be easily transported even if it has a large-sized screen.

A display device (10) includes a plurality of gas discharge tubes (11R, 11G, 11B, . . . ) sandwiched between a front support plate (31) and a plurality of rear support plates (321, 322, . . . 328). The display device further includes: a plurality of display electrodes (2) formed on a surface of the front support plate facing the plurality of gas discharge tubes to extend across tube axes of the plurality of gas discharge tubes; a plurality of signal electrodes (3) formed on surfaces of the plurality of rear support plates facing the plurality of gas discharge tubes to extend along the longitudinal direction of the plurality of gas discharge tubes. Another rear support plate (330) for supporting the plurality of rear support plates is disposed on surfaces of the plurality of rear support plates opposite to the surfaces facing the plurality of gas discharge tubes.

A plasma tube array in which a number of arc each including a phosphor layer inside are arranged. The plasma tube array displays an image by causing discharge inside the arc tubes so that the phosphor layers inside the arc tubes are allowed to emit light. This plasma tube array has a structure with which phosphor layers can be easily aligned in a predetermined direction. The plasma tube array includes alignment members, each of which is disposed at one end of a corresponding one of the arc tubes, and which regulate the postures in a rotational direction of the respective arc tubes.

A plasma tube array according to the present invention includes plural light emitting tubes that have fluorescent material layers inside and are mutually lined up in parallel. The plasma tube array includes pairs of display electrodes that are formed along the respective fluorescent material layers. The fluorescent material layers are disposed in sequence in the longitudinal direction of the light emitting tubes.

A gas discharge tube includes: a elongated tube within which an electron-emissive film is formed, and which is filled with a discharge gas and sealed; a plurality of pairs of display electrodes disposed on a display side of the elongated tube; a signal electrode disposed on a rear side of the elongated tube; and an elongated support member inserted into the elongated tube and extending in the length direction of the elongated tube. The support member has a curved shape so that a curved inner surface thereof forms a discharge space, has longitudinally extending opposite edges, and has a phosphor layer formed on the inner surface of the support member. The support member further has an end wall at each of longitudinally opposite ends thereof. The end walls and the curved inner surface form an elongated depression in the support member.

This invention relates to a single-mode optical fiber having a configuration for effectively reducing bending loss. In the single-mode optical fiber, while an optical core is constituted by inner and outer cores, an optical cladding is constituted by an inner cladding in which "tailing" occurs and an outer cladding. In particular, in a cross section of the optical fiber perpendicular to the signal light guiding direction, when the surface integral values of relative refractive index difference of the optical cladding and optical core with respect to the outer cladding having an average refractive index n.sub.0 are respectively S1 and S2, the optical fiber satisfies a relationship of S1/S2.gtoreq.0.8.
摘要:
A light emitting string is produced by forming a fluorescent layer on a fluorescent layer support member having an opening and configured such as to protect the fluorescent layer, and inserting the fluorescent layer support member into a minute tube. Therefore, when the fluorescent layer support member is inserted into the minute tube, the fluorescent layer is prevented from contacting the interior wall of the minute tube. This prevents the chipping, the separation and the cracking of the fluorescent layer, thereby improving the yield in production of plasma light emitting strings.
