Title: Power converter
Inventor: TOKUNAGA KIICHI
IPC: H02M7/515
Filed: 1980-03-31
Abstract: PURPOSE:To prevent the occurrence of a shortcircuit between the terminals of a power converter by discriminating whether the GTO is OFF or not at the time when an OFF signal is applied to the gate signal of the GTO. CONSTITUTION:A control circuit 51 applies a gate signal through a gate amplifier 61 to GTOs 1-4 to thereby turn ON or OFF the GTOs 1-4 in a desired period and to supply power to the load. The output signals of voltage detectors 21-24 and the output signal of a current detector 31 are applied to a turn-off failure detector 41 to thereby detect whether the GTOs 1-4 fails or not to turn off. When the GTOs fail to turn off by the detection, all the GTOs 1-4 are turned off.

As a result, the magnetization of the blood flow flowing into the photographing region A is so impressed as to be shifted in the 180 deg. direction (negative direction) so that only the blood flow part constitutes the negative signal at the time the excitation pulse P1 is impressed to this magnetization. Then, taking out of only the signal of the blood flow is possible and the bright blood flow image is obtd. if this signal profile is projected at the min. value. The image separating the artery and the vein is obtd. by one time of photographing and the time for photographing is shortened.

Title: Formation of oxide superconductor thin film
Inventor: SATO ISANORI
IPC: H01L39/02
Filed: 1992-01-31
Abstract: PURPOSE:To form an oxide superconductor thin film low in surface resistance and appropriate for a high frequency-applied device. CONSTITUTION:The elements constituting an oxide superconductor contg. Cu as the constitutional element are vapor-deposited on a (100) single crystal substrate 2 in an oxidizing atmosphere to form the oxide superconductor thin film on the substrate. In this case, the start of the deposition of Cu element is retarded to produce a multiple oxide layer free of Cu element on the substrate in a several atomic layer thickness, and the elements constituting the oxide superconductor including Cu element is deposited on the multiple oxide layer. Since the Cu element is not deposited directly on the substrate 2, the CuO crystal grain impeding the surface resistance is not formed. Meanwhile, since the multiple oxide layer has only a several atomic layer thickness, the lattice constant of the (100) face of the substrate is succeeded by the oxide superconductor layer which is c-axis oriented. Accordingly, an oxide superconductor thin film low in surface resistance and excellent in superconductivity such as Jc is obtained.

Filed: 1998-02-24
Abstract: PROBLEM TO BE SOLVED: To prevent a trouble caused by melting of an Si substrate other than effective area at the time of etching by making a trench through anisotropic etching only in the effective area of the Si substrate, i.e., a range for forming a microbridge sensor. SOLUTION: An Si substrate 2 coated with an oxide film 1 is prepared and the oxide film 1 is removed only from the effective area (a) on the surface before forming an insulating thin film 3 and a metal thin film 4 sequentially. The film 4 is then patterned by photolithography and etching to form resistors, i.e., a thin film filter 5 and temperature sensors 6, 7, followed by formation of a passivation layer, i.e., an insulating thin film 8. Subsequently, the thin films 3, 8 are patterned to form a supporting part 9 and an opening 10 and the substrate 2 is etched anisotropically from the opening 10 to made a trench 11 extending below the supporting part 9. Since the surface of the substrate 2 is covered with the film 1 except the effective area (a), it is not melted at the time of making the trench 11.
