Title: Production of hollow yarn separation membrane
Inventor: KOMADA HAJIME
IPC: B01D71/68
Filed: 1987-12-28
Abstract: PURPOSE:To improve water permeability while maintaining fractionation performance by dissolving a polysulfone-base polymer in 2-pyrrolidone and adding N-methylacetamide as one component of an additive, spinning and discharging the mixture into an aq. soln. to produce a hollow yarn separation membrane. CONSTITUTION:2-pyrrolidone is used as the solvent of a polysulfone-base polymer and N-methylacetamide is used as one component of an additive and the mixture is discharged through an annular nozzle and coagulated in an aq. soln. The ppt. of polysulfone is formed by infiltration of coagulation liquid from the inner and outer surfaces while keeping the added N-methylacetamide as a nucleus and it is considered that the parts in which N-methylacetamides are brought into contact with each other form micropores and contribute to formation of a network porous layer and cavities. Furthermore the solubility of polysulfone into 2-pyrrolidone is made good and therefore the main chain of the polymer spreads into the soln. and homogeneous fine pores are formed on the surface of the membrane. Therefore the membrane excellent in water permeability while maintaining fractionation performance is obtained.

Title: Method for correcting thrust of linear dc motor
Inventor: YAMAMOTO HARUMASA
IPC: H02P7/00
Filed: 1999-11-29
Abstract: PROBLEM TO BE SOLVED: To provide a method for correcting the thrust of an LDM in which variation of speed or vibration can be reduced at the time of low speed traveling and control accuracy of stop position can be enhanced by correcting variation of thrust with respect to the driving current of the LDM. SOLUTION: In the method for correcting variation of thrust due to uneven field of a linear DC motor in the traveling direction, coil current is corrected by introducing a flux density function dependent on the relative positional relation of a coil and a magnet in response to a current command. Consequently, a thrust being generated in the traveling direction is corrected and the thrust is made linear to the current.
