Title: Trimming circuit and method for improving accuracy of current detection
Inventor: LAGERQUIST ROLF
IPC: H02P6/00
Filed: 1997-09-19
Abstract: PROBLEM TO BE SOLVED: To supply a phase current accurately by varying the magnitude of a first commutative applying current from the original magnitude toward a second commutative applying current. SOLUTION: A first current path passes through upper and lower drivers 14, 22 while second current path passes through upper and lower drivers 18, 20. The current flowing through an regulative detection transistor 32 is regulated such that the current flowing through the second current path will be substantially equal to the current flowing through the first current path. Since the ration between a mirror device (detection transistor 32) and a power device (upper and lower drivers 14, 18, 20, 22) can be regulated in every chip using the regulative detection transistor 32, current of each phase can be measured with high accuracy.

Title: Production of magnetic powder
Inventor: TANAKA HIROYUKI
IPC: G11B5/706
Filed: 1986-12-11
Abstract: PURPOSE:To obtain magnetic powder having excellent dispersibility by adding fine nonmagnetic inorg. powder to crystal powder at the time of dissolving away a glass forming component by a dilute acid. CONSTITUTION:After the mixture composed of the basic components of hexagonal ferrite, substitution components for decreasing coercive force and the glass forming component is melted by heating, the mixture is rapidly cooled to form an amorphous material. The amorphous material is subjected to a heat treatment to precipitate the crystal of the hexagonal ferrite which is then subjected to dry pulverization. The fine nonmagnetic inorg. powder is added to the resultant crystal powder and after the powder is wet pulverized, the glass forming component is dissolved away by the dilute acid to extract the crystal of the hexagonal ferrite. The fine nonmagnetic inorg. powder when added to the crystallized matter after the heat treatment at the time of the wet pulverization in the above-mentioned manner is sufficiently mixed with the crystallized matter at the time of the wet pulverization. The fine nonmagnetic inorg. powder intrudes among the particles of the hexagonal ferrite at the time of dissolving the glass forming component in the crystallized matter by the dilute acid in succession thereof and, therefore, the flocculating powder between the hexagonal ferrite particles decreases and the dispersibility is improved.
