IPC: H01B13/00
Filed: 1990-03-13
Abstract: PURPOSE:To reduce the m.p. of an oxide, to inhibit a reaction with the material of a crucible at a low temp. and to produce a superconductor at a low cost by carrying out melting in an atmosphere under a low partial pressure of oxygen when a Y-contg. oxide superconductor is produced by melting. CONSTITUTION:Powdery starting materials such as Y2O3 powder, BaCO3 powder and CuO powder are charged into a platinum crucible and melted by heating at 1,300 deg.C in vacuum or in an atmosphere under a very low partial pressure of oxygen, e.g. an atmosphere of an inert gas such as N2, He or Ar. The resulting melt is rapidly cooled to room temp., pulverized in a mortar and press-molded. This molded body is crystallized by rapid heating to 1,000 deg.C in an atmosphere of gaseous N2 and slow cooling to 900 deg.C and it is further cooled to room temp. in an atmosphere under a high partial pressure of oxygen to produce a Y-contg. oxide superconductor having a compsn. represented hy a formula YBa2Cu3O7-y. Since melting is carried out under the low partial pressure of oxygen, the oxide superconductor is produced at a low cost while preventing a reaction with the material of the crucible at a low temp.

Title: Magnetic resonance imaging method
IPC: G01R33/46
Filed: 1992-03-19
Abstract: PURPOSE:To rapidly and exactly determine a 90 deg. pulse and to drastically lessen the preirracliation for measurement necessary for magnetic resonance imaging by adding a high-frequency pulse for holding symmetry to a nuclear magnetic resonance signal after the generation of this signal. CONSTITUTION:A theta pulse 14 is added to an echo signal 13 right after the measurement of this signal in SE sequence (theta-2theta) consisting of the theta pulse 11 and the 2theta pulse 12 as one of the embodiments of this magnetic resonance imaging method. The added theta pulse 14 is the high-frequency pulse for maintaining the symmetry. The measured signal S is as expressed by equation I. The factor 1-Ecos<2>thetacos2theta of the deviation lies in that cos<2>theta-cos2theta is symmetrical with 90 deg. as both cos<2>theta and cos2theta are symmetrical with 90 deg.. The deviation of the max. value of the measured signal from 90 deg. does not, therefore, arise. The max. angle of the signal exactly captures 90 deg. flip angle even in the case of Tr/T1<=1. Then, the time for repeating the sequence for the purpose of determining the 90 deg. pulse is shortened to the extreme possible extent.
