Title: Production of nickel hydroxide particle
Inventor: MAKIMOTO KUNINOBU
IPC: H01M4/52
Filed: 1994-10-14
Abstract: PURPOSE:To obtain nickel hydroxide particles which are very desirable as a not-sintered anode in an alkali cell because they have a relatively narrow size distribution, high filling density and substantially spherical shapes. CONSTITUTION:An aqueous nickel salt, aqueous ammonia and aqueous alkali hydroxide are continuously fed in a certain proportion into a reaction tank provided with a filtration function.

Title: Ferromagnetic film
Inventor: OSAWA YUICHI
IPC: H01F41/18
Filed: 1992-08-27
Abstract: PURPOSE:To provide a heat-resistant, good ferromagnetic film with high Bs and low Hc by using a Co-Fe alloy containing at least one element selected from specific transition metals. CONSTITUTION:A ferromagnetic film is composed of an alloy whose composition is expressed by CoxFeyTz, where T is selected from Al, Ta, Ti, Zr, Nb, Hf, Mo, and W. Assuming that x, y and z are given in at%, then 73<x<94, 5<y<=15, 1<z<12, and z+y+z=100. The addition of the selected element preferentially produces either (111)-oriented fcc crystal or (100)-oriented hcp crystal. Therefore, the magnetic anisotropy in the film is not significantly large, thus resulting in low Hc. If the T content is less than 1 at% high orientation is not realized. With the T content greater than 12 ate, on the other hand, low Hc is not achieved because of the intermetallic compound between T and Co, especially if the film is heat-treated.
