Title: Device for removing magnetic fine particle contained in plating solution of electroplating device
Inventor: NOMURA HIROSHI
IPC: G11B7/26
Filed: 1991-07-11
Abstract: PURPOSE:To attract and remove the fine magnetic material in a plating soln. and to stably form a plating surface excellent in smoothness by fixing a strong magnet to the inner surface of a plating soln transport pipe in the electroplating device. CONSTITUTION:When a large-area material is electroplated with a metal such as Ni, a fine granular Ni is deposited in a plating soln., hence fine protrusions are generated in the plating soln., and the smoothness of the plating surface of the material is deteriorated. To prevent this defect, plural columnar rod- shaped magnets 2 coated with a synthetic resin as the oxidation and corrosion inhibitor are arranged on the inner surface of a circular hollow plating soln. transport pipe 1 in its axial direction. The plating soln. is allowed to flow in the pipe 1 from the upstream side 3 toward the downstream side 4, hence the fine-particle magnetic Ni powder is attracted by the magnet 2 and removed from the soln., and an Ni plating film free of the protrusions of Ni powder and excellent in smoothness is formed on a large-area material.

Title: Inter-series checking method
Inventor: NOHARA GOO
IPC: H02J3/38
Filed: 1987-07-10
Abstract: PURPOSE:To improve the reliability, by transmitting/receiving power calculated respectively for two series and then obtaining an average level and selecting a generator to be interrupted based on the average level. CONSTITUTION:An average effective power between series A and B is calculated based on effective power C1A-C3A is series A and effective power C1B-C3B in series B. No control is made for an average frequency lower than a judging level. When the average frequency is higher than the judging level, an interruption signal is fed through a signal line C4A to a circuitbreaker CB1 if the absolute value of a difference between the average effective power and a comparison level is equal to or lower than the judging level so as to separate a generator G1 from the system. If the average effective power is lower than the comparison level, an interruption signal is fed through a signal line C5A to a circuitbreaker CB2 so as to separate a generator G2 from the system. If the average effective power is higher than the comparison level, an interruption signal is fed through a signal line C6A to a circuitbreaker CB3 so as to separate a generator G3 from the system. Consequently, the reliability can be improved.
