Abstract: Provided is a coating apparatus where a coated object W is moved relative to an application nozzle 10 located above the coated object, and a coating liquid P is applied to a surface of the coated object via a slit-shaped discharge port 12 at a distal end of the application nozzle. In a coating liquid reservoir 11 storing the coating liquid therein, a coating liquid feeder 14 formed with a coating liquid holding recess 14a in a predetermined pattern shape is rotatably disposed at place above the slit-shaped discharge port. A partition member 13 for dividing the slit-shaped discharge port into plural discharge parts 12a along the longitudinal direction of the slit-shaped discharge port is disposed in the slit-shaped discharge port. The coating liquid feeder 14 is rotated to apply the coating liquid to the surface of the coated object via the discharge parts at places corresponding to the coating liquid holding recess.

Abstract: In the detection of a state where a belt-shaped body W is processed as conveyed through a furnace 10, a conveyance route R for conveying the belt-shaped body through the furnace is set and a processing condition for processing the belt-shaped body in the furnace as conveying the belt-shaped body along the conveyance route is set. A fluid analysis is performed on the assumption that a highly viscous fluid Wa having the same characteristic as that of the belt-shaped body flows along the conveyance route at the same speed as that of the belt-shaped body. The processing state of the belt-shaped body conveyed through the furnace is simulated.

Abstract: In a heating furnace 10 where elongate workpieces fed into the heating furnace are sequentially transferred on fixed beams by walking beams from an inlet area to an outlet area, concaves to retain the workpieces are formed at least on the walking beams. A concave in the inlet area for heating the workpieces is increased in width in a transfer direction, while a concave in the outlet area where the heated workpieces are wholly heated to a uniform temperature and retained in position is formed in a corrugated configuration. Despite curving of an elongate workpiece being heat treated as transferred by walking beams in a direction crossing a longitudinal direction of the workpiece, this ensures that the curved workpiece is properly transferred and adequately corrected for the curving.
