Abstract: A perfect binding apparatus having a plurality of pockets, each of which releasably engage a book to be bound. The pockets are sequentially passed over a glue pot by means of a conveyor chain coupled to each pocket. A hot melt adhesive is applied to the bottom edge of each book as it passes over the glue pot. Gravity, along with the liquidity of the glue, causes a portion of the adhesive to fall away from the book as the pocket transports the book downstream from the glue pot, thereby forming undesirable adhesive stringers. A plurality of heaters are positioned downstream from the glue pot and mounted at an elevation at which the bottom edge of the book just clears the top edge of the heater as the book passes over the heater. The heaters are kept at a temperature which is in excess of the melting point of the adhesive, therefore the stringers are continuously melted and removed from the books as they pass over the heaters.

Abstract: There is disclosed an atomized thin film forming apparatus for forming a thin film by spouting an atomized source solution toward a heated substrate. A pair of inner wall surfaces defined at the upper portion of a film forming nozzle and disposed opposite to each other with respect to the longitudinal direction of a film forming chamber are restricted so as to gradually narrow in the interval therebetween toward a spouting opening in a smooth curve.
