Filed: 1986-10-21
Abstract: PURPOSE:To eliminate the need for the driving power of a stirrer and to permit stirring of a coating liquid with simple constitution by immersing a cylindrical base body together with a stirring member for the coating liquid below the cylindrical base body into the coating liquid and moving the same upward relatively with the liquid surface, thereby forming a coated film on the base body. CONSTITUTION:A lifting screw 17 rotates when a driving machine 16 is rotated. The stirring member 15 for the coating liquid fixed to a supporting member 14 is then lowered together with the base body 12 and is dipped in the coating liquid. The stirring member 15 stirs the coating liquid 13 at this time. The base body 12 is detached from the coating liquid 13 and the coated film is formed thereon when the driving machine 16 is rotated backward. The cylindrical base body is thereby immersed into the coating liquid and the stirring of the coating liquid is executed by the stirring member for the coating liquid, by which the need for the driving power of the stirring device is eliminated and the coating liquid is stirred with the simple constitution.

IPC: B01D63/02
Filed: 1993-09-10
Abstract: PURPOSE:To form a highly reliable terminal sealed part generating no channeling by molding a sealing material into a sheet shape and surrounding the entire periphery of the terminal parts of a predetermined number of hollow fibers by the obtained sheet to integrate the hollow fibers with the sheet and molding the integrated part into the terminal sealed part having a predetermined shape under heating.
