Abstract: An electronic light radiation tube wherein a cathode and an anode disposed as spaced from each other by a small spacing are housed in an envelope enclosing therein a luminous gas, and a magnetic field is applied to the envelope so as to cause magnetic lines of force of the magnetic field to pass through the envelope, while the magnetic lines of force which have passed through the cathode are prevented from passing through the anode, whereby electrons emitted from the cathode are caused to collide at a high efficiency with the luminous gas throughout the entire interior space of the envelope to excite the gas, and highly uniform light radiation can be realized over the entire envelope.

Abstract: A suede woven fabric comprises a warp yarn selected from the group consisting of polyester textured yarn, polyester filament yarn and polyester spun yarn, and a weft yarn of polyester island filaments whose mean thicknesses in denier are within the range from 0.05 to 0.50 and whose degree of variation of thickness is 15 to 60%; wherein a portion of said island filaments on at least one surface of the fabric is raised to form piles of individual island monofilaments whose mean lengths are from 0.5 to 4.0mm; wherein the number of floating points on said weft yarn, whose number of floats in within the range of 3 to 11, is 100 to 500/cm.sup.2 of woven fabric, and wherein the relation between the shear stiffness G.sub.0.5 at a shear angle of 0.5.degree. and the stiffness G.sub.5 at a shear angle of 5.degree., represented by G.sub.5 /G.sub.0.5, is 1.5 to 15.
