Abstract: A film (7) is formed by electrodeposition, thermal CVD, or spraying. After that, the film is irradiated with a laser beam. Carbon nanotubes that form the film (7) are disconnected by laser irradiation, so that the density of the carbon nanotubes is optimized. When the film (7) is formed in this manner, stable emission can be obtained from a cathode structure (5).

Abstract: An improved baffle (24) for directing the light discharged from a deuterium lamp includes a plate-like member configured as a cylindrical segment (25), an aperture (27) provided through a central portion (26) of the member, and a flattened portion (26) about the aperture. The flattened portion is of such size and has a surface of such reflectivity as to substantially eliminate interference ring(s) of discontinuous light intensity from the light output of the lamp. A deuterium employing the improved baffle affords the advantage of markedly-increased light intensity, as compared with prior art baffles, at selected wavelengths.

Abstract: This invention provides a compact, efficient and well-designed circular fluorescent lamp with high output power. The circular fluorescent lamp has less non-luminant region and good characteristics of luminous intensity distribution, and keeps high level of lamp lumen output. Circular arc tubes are disposed concentrically on the same plane. Electrodes are attached to the tube-end parts of the one side of the circular arc tubes respectively, and the other tube-end parts of non-electrode side are sealed. The circular arc tubes are joined each other near the tube-end parts of the non-electrode side with a bridge-jointed portion, so that a discharge path is formed between the electrodes inside the arc tubes. The tube outer diameter of the circular arc tubes is 14 mm, the circle outer diameter of the outer circular arc tube is 150 mm, and the circle inner diameter of the inner arc tube is 90 mm. The distance measured along the center line of the tube from the point corresponding radially to the end part of the bridge-jointed portion to the sealed tube-end part of the outer circular arc tube is 11 mm, and the distance measured along the center line of the tube from the point corresponding radially to the end part of the bridge-jointed portion to the sealed tube-end part of the inner circular arc tube is 6 mm.

Abstract: To increase the resistance of a tubular compact fluorescent lamp against akage, particularly at the cross-connecting portion (4) of a U-bent discharge vessel having two leg portions (2, 3), the cross-connecting portion is shaped to have generally parabolic cross section, in which the cross-sectional area of the parabola is about the same as the cross-sectional area of the generally circular leg portions of the U-shaped discharge vessel (1). This provides for better distribution of the glass material of which the discharge tube is made, and hence greater resistance to breakage. The parabolic cross section is terminated at the inner side of the U-bend by an essentially flat, or slightly curved base surface (16), merging with rounded corners (16a) with the parabolic side surfaces. Preferably, the relationship of the radius of curvature (R.sub.P) at the apex of the parabola to the radius of curvature (R.sub.B) of the transition regions (16a) at the corners between the base (16) and the parabolic side surfaces is between about 0.7 and 1.1. The uniform distribution of wall thickness reduces manufacturing defects and breakages.

Abstract: A cathode-luminescent panel lamp (20) includes an evacuated tube (21) having a phosphor coating (25) on the inside surface of a face plate (24). An electron gun (28) is arranged to discharge at least one conical beam of electrons toward the coating to form an electron cloud within the tube. Shaping electrodes (29,30) positioned within the tube distribute and normalize the electron density of the cloud as a function of the angle (.theta.). The electrons pass through a field-separating mesh (39) to impinge upon a secondary emission mesh (40), which amplifies the electron density. The amplified electrons excite the phosphor coating to produce light of substantially-constant intensities across the face plate. The improved lamp may be used to back-light an LCD or in a stadium display.
