Abstract: PURPOSE: A fire control apparatus is provided to improve electromagnetic interference properties by using a switching mode power supply circuit which uses a metal oxide semiconductor field effect transistor integrated circuit and a high frequency transformer. CONSTITUTION: A fire control apparatus comprises a power supply unit which changes a high voltage AC external power supply into a low voltage DC power supply. The power supply unit changes an AC power supply applied in an external power input terminal(P1) into a DC power supply through a bridge diode(D1) and a smoothing electrolytic capacitor(C2). A high frequency transformer(T1) drops the voltage of the transformed DC power supply. AC voltage outputted in the high frequency transformer is controlled by a zener diode(ZD1) and a control of a metal oxide semiconductor field effect transistor integrated circuit(U1) consisting of resistances(R4, R5) and a photo coupler(U2).

Abstract: PURPOSE: A method for manufacturing complex metal oxide powder is provided to uniform the particle of the complex metal oxide powder in a perovskite structure based on a low temperature process. CONSTITUTION: Two or more kinds of metal organic compounds or metal salts are respectively dissolved in a solvent and are mixed. A precipitating agent is added into a mixed solution to form complex metal precipitates. A gelating reaction is implemented to form complex metal compounds. The compounds are thermally treated at a temperature between 800 and 1100 degrees Celsius. The metal organic compounds or metal salts include metal selected from Ba, Mg, Ca, Pb, Ti, Fe, Sr, Zr, Ta, Bi, Ta, and Nb. The precipitating agent is selected from K_2CO_3, KOH, and the mixed solution of the same.
