Title: Electromagnetic wave absorption panel
Inventor: KITAKOGA YOSHIYUKI
IPC: H01Q17/00
Filed: 1987-06-05
Abstract: PURPOSE:To obtain a low reflection factor and a high absorption factor, by composing a stereoscopic circuit of conductive thin films and providing the conductive thin films with pores properly so as to vary an apparent intrinsic surface resistance in the traveling direction of electromagnetic waves. CONSTITUTION:Each element in a stereoscopic circuit is cylindrically formed of conductive thin films 2, and these conductive thin films 2 are provided with pores 2a properly so that an apparent intrinsic surface resistance is varied in the traveling direction of electromagnetic waves 3. The electromagnetic waves 3 traveling inside the cylindrical matters are converted into heat energy by the surface resistance of the conductive thin films 2 and they are attenuated. Further, if the intrinsic surface resistance is made sufficiently high as needed on the plane where the electromagnetic waves 3 are introduced, the electromagnetic waves can be reflected much less on the introduction plane. Hence low reflection and high absorption of the electromagnetic waves 3 can be attained.

Filed: 1998-05-22
Abstract: PROBLEM TO BE SOLVED: To provide a lighting equipment improved in visibility by reducing translucency in the neighborhood of a peripheral part of a display pattern provided on a display panel lower than that at the central part of the display pattern. SOLUTION: Printing ink is increased in the density in the neighborhood of a peripheral part 21a of a display pattern 21 higher than that in the central part. In such a manner, the translucency is made to be lower in the neighborhood of the peripheral part 21a than that in the central part. Therefore, not only the direct light from a light source but the light reflected from the boundary part across the air on the surface side of a display panel 1 are collected together in the neighborhood of the contour peripheral part 21a of the display pattern 21. Here, since the printing density is high in the neighborhood of the contour peripheral part 21a, the light transmitted through the part is decreased in the quantity, and this part does not look faded in color compared with the central proximity of the display pattern 21.  As a result, the contour of the display pattern 21 does not look blear either.
