Title: Voltage comparison circuit
Inventor: NOZAWA TAKAHIRO
IPC: H03K17/62
Filed: 1993-10-20
Abstract: PURPOSE:To provide a voltage comparison circuit by which a maximum voltage value with few error or a minimum voltage value can be obtained. CONSTITUTION:Input voltage V 1 is inputted in the bases of the transistors Q 1 and Q 3 of differential amplifiers 6 and 7, and input voltage V 2 is inputted in the bases of the transistors Q 2 and Q 4 of the differential amplifiers 6 and 7. The fluctuation of base-emitter voltage VBE can be suppressed even when input voltage difference DELTAV changes because the common emitter current I 3 of the differential amplifier 6 is controlled and at least of either one of the emitter current IE 1 and IE 2 of transistors Q 1 and Q 2 is made always constant (I 0/2) by detecting an emitter current ratio by the differential amplifier 7 and changing the current I 1 and I 2 from current sourcs 8 and 9. The error of output voltage to be determined by input voltage and the base-emitter voltage VBE is suppressed.

Abstract: PURPOSE: To integrally bake a magnetic material and conductor by obtaining the magnetic material which has an excellent core loss temperature characteristic and is less in loss in an MHz band by baking powder obtained by heating a solution containing a complex of Fe nitrate, Mn nitrate, and Zn nitrate which respectively become Fe2 O3 , MnO, and ZnO in the magnetic material and amino acid. CONSTITUTION: Highly pure iron nitrate, manganese nitrate, and zinc nitrate are dissolved in pure water so that the amounts of the iron nitrate, manganese nitrate, and zing nitrate dissolved in the pure water can respectively become 51.0-52.5mol% (in Fe2 O3 equivalent), 37.0-45.0mol% (in MnO equivalent), and 12.0-2.5mol% (in ZnO equivalent). α-amino acetic acid is added to the solution by about 20wt.% and the solution is well strirred up. Then the solution is heated to evaporate the water. After the water evaporates, the residue causes autoignition and power is obtained. After very small amounts of SiO2 , CaO, and HfO2 are added to the powder, the powder is mixed and pulverized. After pulverization, the power is granulated and the granules are molded to a toroidal body. Then the molded body is baked at about 800 deg.C.
