Abstract: PURPOSE: To remove only reaction inhibitive components contained in a chemical copper plating soln., by using an electrodialyzer equipped with cation exchange membranes and/or anion exchange membranes.  
     CONSTITUTION: After continuous use of a chemical copper plating soln., SO 4   2-  formed from copper sulfate added for replenishing copper ions, HCOO -  formed from formaldehyde used as a reducing agent for copper ions, Na +  formed from  caustic soda which keeps the plating soln. alkaline, and CO 3   2-  formed from absorbed CO 2 , accumulate in the plating soln. and inhibit the reaction. To remove  these components, the solns. contained respectively in a plating tank 1, an electrode  soln. tank 10, and a concd. soln. tank 14 are delivered by circulating pumps 5, 11,  15 while being kept at 0.05atm to an electrodialyzer 9 which is equipped with eleven cation exchange membranes facing to the cathode, and with eleven anion exchange membranes facing to the anode, hereby these solns. are dialyzed, and one or more reaction-inhibitive components are removed selectively from these solns., hence the plating soln. is regenerated.

Title: Spatter apparatus
Inventor: ARAIHARA SATOSHI
IPC: C23C14/36
Filed: 1981-05-21
Abstract: PURPOSE:To improve the film thickness distribution and the film quality of a film to be deposited on a sample surface, by an a magnetron type spatter apparatus in which the concave of a bowl shape target is arranged to be faced with a sample. CONSTITUTION:As the bowl shape target 2 is used, the center of the sample is spattered from the surroundings, and since the periphery of the sample 4 becomes nearer to the target 2, the film thickness distribution can be brought into uniformity. Further, if the bottom center of the spatter plate of the target 2 is removed to have a through-hole 5, the film thickness distribution will not be influenced at all, and in stead, the exhaustion of the zone between the sample 4 and the target 2 and through the through-hole 5 will be facilitated as shown at a broken arrow. Accordingly, the plasma zone can be cleaned, and the quality of the film to be deposited on the surface of the sample 4 can be improved.

Filed: 1995-04-03
Abstract: PURPOSE: To provide a method which restrains a trapped magnetic flux from being dropped with time when a superconducting tube is manufactured and to provide a superconducting tube in which a drop with time, in a trapped magnetic flux is small. CONSTITUTION: A cylindrical superconductor is cooled down to a critical temperature or lower, a magnetic field Bb at Betake-off <B<Bemax is applied in the axial direction of the tube from the outside of the superconductor, an external magnetic field is reduced to a zero magnetic field, and the superconductor is magnetized.
