IPC: H01F6/06
Filed: 1990-07-09
Abstract: PURPOSE:To make it possible to suppress the reaction of a dielectric film as a spacer by a method wherein the superconducting characteristics of the superconducting wiring, to be led out to outside a spiral pattern from the center part of the pattern, is developed by lamp annealing. CONSTITUTION:An oxide superconducting film is deposited on an MgO single crystal substrate 3, a coil 4 is obtained by patterning into a spiral shape, and a dielectric film, which is composed of MgO, SrTiO3, SiO2, Al2O3 and the like, is deposited thereon, a planarization operation is conducted subsequently, and a spacer is formed. Besides, an oxide superconducting film, to be used for a lead-out wiring, is deposited and the whole body is annealed by the light 7 emitted from the source of lamp light. Subsequently, a superconducting wiring 6 is obtained by patterning. When above-mentioned lamp annealing is conducted, the temperature is sufficiently high on the part located about a micron from the surface, but the temperature suddenly goes down as going deeper. Accordingly, the lead-out wiring can be annealed sufficiently, and the reaction with the internal dielectric film is small. As a result, a highly efficient oxide superconducting coil can be formed without impairing the superconducting characteristics of the material used.

Title: Masking method in leak test
Inventor: YAMADA MASAHIRO
IPC: G01M3/20
Filed: 1981-11-16
Abstract: PURPOSE:To prevent the intrusion of test gas into the part other than a masking space, by injecting a gas other than helium or the like for testing in the space formed by flexible members which hermetically seal an object to be tested in a double mode. CONSTITUTION:An observing window 1, which is the object to be tested, is tightly sealed by the flexible, tightly sealing cover members 2 and 3 such as vinyl in the double mode. In the space 5 formed by these members 2 and 3, the gas such as nitrogen other than the test gas such as helium or hydrogen is supplied and pressurized through a pipe 4. Under this state, the masking space 7 between the inner member 2 and the window 1 is evacuated through an exhaust pipe 6 to obtain a vacuum state. Thereafter, the test gas such as helium is injected into the space 7 by a supply pipe 8. This is repeated three times and the helium gas in the space 7 is well substituted. Then the amount of leakage of the window 1 is measured by using a helium leakage detector, a mass analyzing device, and the like. The intrusion of the helium gas to the part other than the masking space is prevented in this method. Thus the amount of the leakage can be accurately measured.
