摘要： To provide a novel surface emitter incorporating an LED element improved in waterproofness or other practical functionality to enable the surface emitter to be used not only for a sign but also for other various applications, in appearance and in workability, and an internally illuminated sign incorporating the same surface emitter. A surface emitter 1 according to the present invention has a flexible substrate 11 having electric wiring 12, a plurality of LED elements 13 disposed substantially regularly on the substrate 11, and a top film 14 disposed on the LED elements 13 in a stretched manner. When the top film 14 is disposed on the substrate 11 in a stretched manner, the top film 14 is applied to the substrate 11 to come into close contact with projections and depressions formed by the LED elements 13. More specifically, a vacuum pressure bonding process is used in which a space between the LED elements 13 and the top film 14 is evacuated, and the top film 14 is heated and pressure-bonded to the surface of the LED elements 13.

摘要： A silver halide photographic emulsion is disclosed. The emulsion contains core/shell type silver halide grain comprising a core essentially consisting of silver iodobromide and at least one shell essentially consisting of silver iodobromide or silver bromide, in which said silver halide emulsion have an average silver iodide content of less than 7 mol %, and said core has a silver iodide content of not less than 10 mol % a shell arranged at the outermost portion of said shell has a silver iodide content of not more than 5 mol %, and said core and shell have a distinct core/shell structure. The emulsion is excellent in developing activity, ready in contrast control and excellent in processing stability, with out deteriorating both sensitivity and pressure resistance property.
