Abstract: A light transmission tube includes a tubular clad and a core section having a higher refractive index than that of the tubular clad, said light transmission tube is characterized in that a belt-like reflecting layer is formed between the tubular clad and the core section, extending in the longitudinal direction of the tubular clad, in a manner such that a light passing through the core section is reflected and scatterred by the reflecting layer and then emitted from an outer surface area of the tubular clad, which outer surface area is located opposite to one side of the tubular clad where the reflecting layer has been formed. Further, the reflecting layer may be so formed that a light is allowed to be emitted in a plurality of directions. Moreover, the belt-like reflecting layer may be formed into a spiral configuration. The width of the belt-like reflecting layer may be changed in the longitudinal direction of the light transmission tube. The tubular clad is allowed to have a non-circular cross section.

Abstract: An electromagnetie-wave shielding and light transmitting plate suitable for an electromagnetic-wave shielding filter for a PDP, which has good electromagnetic-wave sheilding efficiency and light transparency, can provide distinct pictures, and can yet be easily made, is provided. The electromagnetic-wave shielding and light transmitting plate is formed of two transparent base plates and an adhesive layer made of EVA in which conductive particles are dispersed and mixed. The base plates are integrally bonded together by the adhesive layer. Adjusting the particle size and the dispersed amount of the conductive particles enables the manufacture of plates having desired electromagnetic-wave shielding efficiency, in addition, good light transparency, without moire phenomenon. Using an adhesive sheet formed by mixing the conductive particles into the EVA facilitates the manufacture of the aforementioned plate.

Abstract: An electromagnetic-wave shielding material, such as a conductive mesh member 3, is bonded to a front surface of a PDP body 20 by transparent adhesives 4B, 4C and a transparent base plate 2 is bonded to a surface of the electromagnetic-wave shielding material by transparent adhesives 4A so that they are integrated together. In this way, electromagnetic-wave shielding efficiency is imparted to a display panel itself, thereby lightening its weight, making its wall thinner, reducing the number of parts, and thus improving the productivity and reducing the cost.

Abstract: In an optical transmission tube comprising a tubular cladding and a core within the cladding having a higher index of refraction than the cladding, a strip-shaped reflecting layer is longitudinally extended between the cladding and the core. Light passing through the core is reflected and scattered by the reflecting layer to emerge from the tube through an area of the outer surface of the cladding opposed to the reflecting layer. The optical transmission tube is prepared by dispersing scattering particles in a monomer solution; filling a tubular cladding with the monomer solution; resting the cladding horizontally for allowing the scattering particles to settle on a lower inner surface of the cladding; and thereafter, causing the monomer solution to polymerize and solidify within the cladding.

Preparation of the thermosetting resin is carried out by previously mixing a part of the copolymer of ethylene-vinyl acetate with the hydrocarbon resin to obtain a mixture, mixing residual amount of the copolymer of ethylene-vinyl acetate into the mixture, and adding the organic peroxide to mix.
