Abstract: In an anode-side assembling process, a first end of a glass tube is fused to a rearward end of an electrode bar secured to an anode-side lead to produce a primary sealed product. In a cathode-side assembling process, a ring-shaped cathode is secured by caulking to a forward end portion of an electrode bar secured to a forward end of a cathode-side lead to produce a cathode member. In an assembling process, a second end of the glass tube of the primary sealed product is fused to a rearward end of the electrode bar secured to the cathode-side lead of the cathode member to produce a xenon discharge tube. A trigger electrode, which is composed of a transparent conductive film, is formed on a surface of the glass tube so that the light-transmissive sealed tube-coating ratio specified by the transparent conductive film is within a range of 5 to 30%.

Abstract: This invention provides a means for improving rapid drying ability upon development and preservability of developing solution which comprises interposing a layer of water-soluble polymer having an average molecular weight of 300,000 or more between a non-photosensitive hydrophilic colloid layer and a hydrophobic polymer layer coated on the opposite side of a support to a silver halide photographic emulsion layer, or storing dried the above silver halide photographic photosensitive material with the interposed layer at the glass transition temperature of the hydrophobic polymer or higher.

Abstract: A film applying method in which a coating solution is applied by a solution injector having an edge guide onto a support member as a freely falling coating film, includes forming a solution contact surface of the edge guide to have one of a radius greater than 1.0 mm or a width d greater than 0.7 mm when the coating solution has at least one of a viscosity greater than 45 cp and a dynamic surface tension difference greater than 8 dyne/cm. The edge guide solution contacting surface is narrowed to have a radius less than 1.0 mm or a width d less than 0.7 mm when the coating solution has at least one of a viscosity less than 45 cp and a dynamic surface tension difference less than 8. In a second embodiment, the coating solution is prepared to have at least one of a viscosity greater than 45 cp and a dynamic surface tension difference greater than 8 dyne/cm when the solution contacting part of the edge guide has either a radius r greater than 1.0 mm or a width d greater than 0.7 mm.
