Abstract: PROBLEM TO BE SOLVED: To obtain a gas treatment apparatus and gas treatment filter which are capable of efficiently developing a photocatalytic reaction and are small in size and high in treatment capacity. SOLUTION: The gas treatment unit 1 has a multiplicity of photocatalytic fibers 3 held between metallic filters 2 as air permeable members in a bundled state. Photocatalytic fiber 3 is formed by depositing a photocatelyst having the refractive index higher than the refractive index of a fiber-like guide body having projections on the surface of the light guide body. The gas to be treated flows through the gaps of the many photocatalyst fibers 3 bundled between the metallic filters 2. On the other hand, the UV rays from a UV light 6 are cast to the end faces of the photocatalystic fibers 3 and leaks out to the photocatalyst on the surface of the light guide bodies while propagating in the photocatalytic fibers 3. At this time, the malodorous components, etc., included in the gas are brought into contact with the photocatalyst excited by the UV rays and are decomposed by the photocatalytic reaction.

Abstract: PROBLEM TO BE SOLVED: To decrease the weight of a CRT as a whole without decreasing the shock resistance, pressure resistance or the like of a funnel. SOLUTION: The funnel for a cathode ray tube is obtained by chemically strengthening glass containing, by wt.%, 45 to 60% SiO2, 0.1 to 15% Al2O3, 5 to 20% Na2O and 15 to 30% PbO. The cathode ray tube is obtained by using the above funnel for a cathode ray tube.
