Latest Patents

Ujihara's latest patents include a method for dual surface film coating of a running web. In this process, a first coating liquid is applied to one surface of a continuously running web, and the fluidity of the first coating layer is eliminated by an air blower. Following this, the web is float supported over a cylindrical blower by static gas pressure. A second coating liquid is then applied to the opposite surface of the web in the vicinity of the float region, either by a freely falling curtain film or by a pressure extruded jet film. Another significant patent is for a film casting apparatus designed for the purification of photographic materials. This process effectively and rapidly desalts gelatino silver halide emulsions for photographic light-sensitive elements by forming a thin film of the emulsion, gelling it through cooling, and subsequently washing it with cold water.
