Title: Manufacture of rigid magnetic film
Inventor: HARA KENJI
IPC: H01F1/032
Filed: 1984-04-12
Abstract: PURPOSE:To stabilize a magnetic film up to the neighborhood of the melting point of a plating metal, and to make the film to enable to endure sufficiently formation of a finely magnetized pattern according to projection of laser by a method wherein electrodes are immersed in a plating liquid dispersed with rigid magnetic particles, and electrolysis is performed using the substrate as a cathode, and by making a magnet to come in contact with the back of the substrate. CONSTITUTION:Electrolysis is performed using a substrate 3 as a cathode, and by making a magnet 2 to come in contact with the back of the substrate 3 in a plating liquid dispersed with rigid magnetic particles 1 of 5-100g/l to form a metal film containing the rigid magnetic particles 1 on the substrate 3. Because the particles easily oxidizable such as the Nd-Fe, Sm1Co5 or Sm2Co17 particles out of the rigid magnetic particles reach with water when dispersed directly in an aqueous solution, protective films are formed on the surfaces of the particles before to be dispersed in the plating liquid. As the protective film thereof, a metal film of Cu, Ni, Cr, Ag, etc. or the oxide, the nitride, the carbide of the metal to hardly react with water, and to hardly generate a hydroxide film, etc. on the surface is suitable. Moreover, to reduce resistance when electrolysis is to be performed, it is favorable to cover the surfaces of the rigid magnetic particles with conductive films.

Title: Method of regenerating electroless copper plating solution
Inventor: OIDA MASAHIRO
IPC: C23C18/40
Filed: 1981-05-18
Abstract: PURPOSE: To regenerate a plating solution, by supplementing constituents corresponding  to the consumed constituents into an electroless copper plating solution after it is used,  permitting impurities present in the solution to be adsorbed onto an adsorbent containing activated carbon as a major component so that the impurities are removed, and  then supplementing an alkali hydroxide.  
     CONSTITUTION: After the plating solution has been used which contains copper salts  such as copper sulfate, a complexing agent for copper such as tartaric acid, formaldehyde as reducing agent, and other various additives, and whose pH is adjusted to  about 11.5W13.0 by the addition of an alkali hydroxide, the same copper salts as those  mentioned before and formaldehyde are replenished to compensate the consumed copper  salts and formaldehyde, and an adsorbent consisting of activated carbon and diatomaceous earth in a ratio of about 1:0W1 is added in an amount of about 2W20g/l, and  after it is treated at a temperature in the range of about 10W70°C for about 0.5W20hr,  it is filtered so that various impurities that have been resulted from side reactions and  have been adsorbed are removed. Then, since the pH of the plating solution is lowered  due to the supply of the copper salts and formaldehyde, an alkali hydroxide is added to  restore it to a prescribed pH.

IPC: G11B5/02
Filed: 1998-03-24
Abstract: PROBLEM TO BE SOLVED: To simultaneously read the data, which are formed by applying a magnetic body, and recorded data using a single magnetic head by extracting the data, which are formed by applying the magnetic body, from the head element having a stronger magnetic field or the one side polarity head element among a pair of head elements which are different in strength or polarity of magnetic fields.

Title: Dressing method for grinding wheel for rolling roll
Inventor: IIFUSHI JUNICHI
IPC: B21B28/04
Filed: 1985-04-11
Abstract: PURPOSE:To improve grinding efficiency by disposing a dressing tool to the non-contact part of a grinding wheel and rolling roll and pressing the tool to the side end face of the grinding wheel during grinding. CONSTITUTION:A supporting shaft 4 of the grinding wheel 3 is supported by a bearing box 5 and is pressed to the outside peripheral surface of a work roll 1 by the operation of a hydraulic cylinder 6. The dressing tool 10 is provided to the non-contact part of the wheel 3 and the roll 1 and is pressed to the bore part on the grinding surface of the wheel 3. The tool 10 is pressed always under the specified force to the wheel 3 by the operation of a hydraulic cylinder 11. The tool 10 follows up consequently the wear of the wheel 3 even if the wheel wears. The tool 10 removes successively the build-up part of the wheel 3. Since the build-up part which is the cause for the oscillation of the wheel 3 is removed, the stable grinding with the wheel 3 is made possible. The grinding efficiency is thus improved.
