Title: Nuclear magnetic resonance image diagnosing method
Inventor: CHITOKU KAZUO
IPC: A61B5/055
Filed: 1988-06-22
Abstract: PURPOSE:To prevent resolution from being lowered with a partial volume effect by plurally dividing slice thickness, adding respective pictures and obtaining a final picture when the slacing of an object part in a checked body is executed with an inclining magnetic field coil. CONSTITUTION:At first, the division is executed concerning an area to be photographed, especially, a thickness direction. Then, the thickness and number of the slicing is set. Next, a signal in the expanding period of the first slice is fetched synchronism with the R-wave rising of an ECG(Electrocardiogram). After that, a signal in the contracting period of the first slice is fetched with being delayed from the R-wave rising almost by 200msec. Further, even concerning a second slice surface, the signals in the expanding and contracting periods are samely fetched. Thus, the slicing is continued only for the slice number, which is set at first, and pictures at the expanding and contracting periods in the respective slices are completed. Then, when subtraction is executed between the picture at the expanding and contracting periods in each slice, the drawing of a blood vessel is obtained in each slice. Here, after prescribed picture processing is executed, the respective slices are added and the blood vessel drawing picture in a photographed range, which is set at first, is obtained.

IPC: C23C14/58
Filed: 1988-06-20
Abstract: PURPOSE:To prepare superconductor crystals having uniform superconducting critical temp. with good reproducibility by conducting a fixed electric current through a thin film of a ceramic superconducting material formed on an insulative crystalline substrate. CONSTITUTION:A loading electrode 1 is formed on both ends of a surface of, for example, a sapphire substrate 11. Then, a thin film 2 of a ceramic superconducting material is coated on the surface of the substrate 11(including said electrode 1) while feeding a fixed electric current from a source 4 for the fixed electric current, and the feed of the electric current is continued until a drop of voltage in the thin film 2 attains automatically approximately zero. Joule heat generates due to a large electric resistance of the thin film 2 when electric current is conducted through the thin film 2, and the thin film 2 is annealed by the generated Joule heat and continues epitaxial growth. Thus, an electric resistance of the thin film 2 is decreased gradually. The heat generation becomes also smaller gradually resulting spontaneous cease of annealing, and at the same time the thin film 2 is transformed to thin film crystals 26 of the superconductor.
