Abstract: An anhydrous fiber-dyeing apparatus using vacuum transfer, includes: a hollow drum in which a plurality of fine holes are formed to penetrate therethrough, and a fiber to be dyed are wound around an outer surface thereof; a transfer film covering the outer surface of the fiber wound around the drum and having an inner side surface coated with a dye; heating means heating the fiber wound around the drum; and a vacuum means suctioning air through an inner space of the drum to form a vacuum pressure through the fine holes of the drum.

Abstract: A three-dimensional out sole having a pattern having improved quality and durability has a dye permeated into the surface of the outsole. A depth to which the dye penetrating the micropores is 0.08 mm to 0.12 mm. The dye is permeated into the microspores through vacuum suction. The dye is digitally printed on a thermoplastic sheet. The thermoplastic sheet on which the dye is printed is heated to be softened with flexibility. The softened sheet having flexibility is closely attached to a surface of the shoe outsole having the three-dimensional shape through vacuum adsorption and then is permeated therein.

Abstract: Method for diagnosing a pneumatic control valve by using a positioner model includes: establishing relational expression for outputting valve stem displacement according to control pressure, the relational expression including parameters for the characteristics of a positioner, an actuator, and a valve, determining initial parameter value by adjusting the values of the parameters until the difference between a measured value for a normal operation of the pneumatic control valve and output value obtained by the relational expression is smaller than predetermined error limit, determining diagnostic parameter value by adjusting the values of the parameters until the difference between a measured value for a diagnostic operation of the pneumatic control valve and an output value obtained by the relational expression is smaller than a predetermined error limit, and comparing the initial parameter value and the diagnostic parameter value so as to determine whether the pneumatic control valve has abnormality.

Abstract: The present invention provides a method for learning latest data considering external influences in an early warning system, and the early warning system for same. The method for learning latest data considering external influences comprises the steps of: an early warning processing device categorizing device monitored variables according to external influences; and the early warning processing device differently applying a pattern learning method for each of the categorized monitored variables.

Abstract: Disclosed herein is a mass production system and method of synthesized carbon nanotubes. The system is configured to completely open the reaction chamber to an outside during synthesis of the carbon nanotubes in the reaction chamber while allowing a specific gas to occupy a predetermined region within the reaction chamber, thereby blocking introduction of external air into the reaction chamber which is opened to external air.
