Title: Production of ferrite powder
Inventor: HIRANO SHINICHI
IPC: C01G49/00
Filed: 1986-11-22
Abstract: PURPOSE:To produce ferrite powder in excellent raw material conversion at low temperatures by simple operation, by subjecting a blend of iron oxide or hydroxide with hydrothermally reactive metallic powder to hydrothermal reaction treatment. CONSTITUTION:A blend consisting of powder, e.g. hematite, geothite or mixture thereof, etc., selected from iron oxides other than magnetite, hydroxide and mixtures thereof with at least one metallic powder, e.g. Fe, Co, Ni, Mn, etc., is hydrothermally reacted in the presence of water under pressure. The purpose is advantageously attained under reaction condition of about 200-300 deg.C under about 50-200 atm for about 2hr. Ferrite is readily formed by this hydrothermal reaction. As a result, the following effects are recognized. Operation processes are more readily carried out than those of conventional methods and raw material conversion is excellent (about 100%). The reaction proceeds at a relatively low temperature even in the case of raw materials containing impurities present therein, etc.

Title: Method and apparatus for suppressing and deleting ground-fault accident ground-fault current of direct grounded or resistance grounded line
Inventor: TERUI SEIICHI
IPC: H02H9/02
Filed: 1992-08-31
Abstract: PURPOSE:To set a ground-fault current almost to zero and to reduce a ground- fault accident to a minimum limit by superposing a ground-fault deleting voltage of the same vector as that of a voltage to ground of a ground-fault point on a line by using a zero-phase impedance to operate at a high impedance to a zero-phase at the time of generating a ground at the line. CONSTITUTION:When a one-phase ground-fault occurs, a one-phase ground-fault current Ig flows, and a zero-phase voltage V0 is V0=Ero-2ZsIg+Eso+ZsIg+Eto+ZsIg=0 in terms of power source impedance Zso at an input side. Accordingly, the zero-phase voltage is nearly zero. When the current Ig flows, is detected by an instrument transformer ZCT, amplified by an amplifier AMP and a ground-fault deleting voltage Eroe is superposed on a line by a zero-phase transformer ZTr, a current Ig to flow is Ig=(Ero-Eroe)/(2Zs+Rg), where when an amplification factor of the amplifier is K and Eroe=KIg, the current Ig becomes Ig=(Ero-KIg)/(2Zs+Rg). Thus, when the Ig is obtained, the Ig becomes Ig=Ero/(2Zs+Rg+K), and hence when the K is sufficiently increased, the Ig can be approached to '0'.
