摘要： A gyro sensor 10 having a small and simple structure and yet being capable of detecting changes in angular speed with high sensitivity. The sensor 10 includes a giant magnetostrictive member 12 made of a giant magnetostrictive element, a drive coil 18 for vibrating the giant magnetostrictive member 12 by controlling the intensity of a magnetic field applied to the giant magnetostrictive member, and a GMR element (detecting means) 20 for detecting changes in magnetic permeability or remnant magnetization of the giant magnetostrictive member 12. Changes in angular speed around a rotation axis that is orthogonal to a direction in which the giant magnetostrictive member 12 vibrates are detected as the changes in magnetic permeability or remnant magnetization of the giant magnetostrictive member 12 caused by its deformation, which is brought about by the Coriolis force.

摘要： An anisotropic hexagonal barium ferrite sintered magnet is prepared by molding a powder barium ferrite raw material in a magnetic field into a compact and sintering the compact; or by molding a powder barium ferrite raw material in a magnetic field into a compact, disintegrating the compact into particles, compacting the particles in a magnetic field into a second compact, and sintering the second compact. In either case, the raw material contains calcined hexagonal barium ferrite, a silicon component, and a barium component. The resulting anisotropic hexagonal barium ferrite sintered magnet has improved sintered density and coercivity while the method minimizes deformation during sintering which is otherwise caused by the difference between the shrinkage factors in axis c and a directions, and simplifies or omits post-treatment like polishing.

摘要： A monocrystal of a R-T intermetallic compound containing R (at least one lanthanide element inclusive of Y) and T (at least one transition metal element such as Fe, Co, Ni, Cr and Mn) is grown by a solid phase method. First a precursor in which a primary phase of the intermetallic compound and a low-melting eutectic crystal phase exist is prepared. The precursor is successively heated from one end to another end while it is often contacted at one end with a seed crystal. Then the low-melting eutectic crystal phase functions as a flux intergranular substance to ensure the consistent manufacture of a monocrystal aligned with the crystallographic orientation of the seed crystal or at the start-of-heating point.
