Latest Patents

One of Nakajima's latest patents is a vacuum drying apparatus and method designed to reduce the drying time of objects while ensuring a satisfactory surface condition post-drying. This invention features a vacuum pump connected to an exhaust port of a vacuum chamber through a suction pipe. A frequency converter is integrated on the input side of an alternating current motor that drives the vacuum pump. The process involves placing a substrate coated with a coating liquid in the vacuum chamber, where gas is exhausted at a high rate until the solvent evaporation rate reaches a specific vacuum degree. Subsequently, the gas is exhausted at a low rate to allow for gradual solvent evaporation, ultimately returning the pressure in the vacuum chamber to atmospheric levels.
