Title: Production of partially solder-clad bar
Inventor: WAKUTA SEIJI
IPC: B23K1/00
Filed: 1984-11-16
Abstract: PURPOSE:To obtain a partially solder-clad bar which obviates the exfoliation of solder by notching preliminarily the surface to be clad of a copper bar subjected to Ni plating and cladding partially the solder to said surface including the notched part. CONSTITUTION:Ni2 is plated to the copper bar 1 and thereafter the surface 4 to be clad of the bar 10 having the Ni plating is preliminarily notched 5 to expose the bar 1 of the inside having the good adhesiveness to the solder 3. The solder 3 is then partially clad to the bar 10 by rolling by which the desired partially solder-clad bar is obtd. The production of the partially solder- clad bar without the exfoliation of the solder part is thus made possible. The clad bar is used as a lead frame for a diode, transitor, etc.

Title: Electrostatic image developing developer
Inventor: YAMAZAKI HIROSHI
IPC: G03G9/08
Filed: 1984-11-15
Abstract: PURPOSE:To prevent deterioration of a developer by dispersing magnetic particles into a binder resin to form core particles, forming the outer walls of a hard resin to form microencapsulated magnetic particles, and combining them with a nonmagnetic toner to obtain a developer. CONSTITUTION:A soft resin, such as styrene type, ethylene type, olefin type, vinyl ester type, or acrylate type resin, is used as the binder resin to alleviate impacts against the toner, and the magnetic particles, such as ferrite or nickel particles, are dispersed into this resin. The core particles are coated with the hard resin, such as epoxy, polyamide, or polyurethane resin, to form the outer walls and obtain the microencapsulated magnetic particles. The electrostatic image developer is obtained by combining these particles with the nonmagnetic toner, thus permitting the toner not to attach to the carrier of the capsulated particles, because the outer walls of the hard resin are formed on the core particles, the carrier to be reduced in deterioration, and to be used for a long term.

Title: Magneto-resistive element
Inventor: SAITO MASAJI
IPC: H01F10/08
Filed: 1995-09-21
Abstract: PROBLEM TO BE SOLVED: To improve the reproduced output of a magneto-resistive element consisting of a soft magnetic layer/nomnagnetic layer/magneto-resistive layer. SOLUTION: The soft magnetic layer 2 is formed of Fe-Al-Si-X-C (X is any one among Hf, Ti, Zr, V, Nb, Ta, Mo and W) of a ferrous fine crystalline material. The material has a high saturation magnetic flux density and, therefore, even if the film thickness is reduded, the application of a sufficient transverse bias magnetic field on the magneto-resistive layer 4 is possible. In addition, the specific resistance increases. The specific resistance is large and the reduction of the film thickness is possible and, therefore, the resistance value of the soft magnetic layer 2 increases. The shunt ratio of the stationary current to the soft magnetic layer 2 is thereby lowered and the shunt ratio of the stationary current to the magneto-resistive layer 4 is increased, by which the reproduced output of the magneto-resistive layer 4 is enhanced.
