Title: Production of oxide superconductor
Inventor: NISHIWAKI AKIHA
IPC: H01B12/06
Filed: 1990-09-28
Abstract: PURPOSE:To obtain an oxide superconductor film high in critical temp. and critical current density by allowing the amorphous deposited film having an oxide superconductor composition sputtered under reduced pressure to react with ozone, N2O or O2 at a relatively low temp. and heat-treating the film at a temp. where the film is partially melted to crystallize the film. CONSTITUTION:An amorphous deposited film having an oxide superconductor composition (e.g. Bi-Pb-Sr-Ca-Cu-O-based superconductor) is produced by sputtering under reduced pressure. The film is allowed to react with ozone, N2O or oxygen at <=400 deg.C, then heat-treated at a temp. where the film is partially melted and crystallized to obtain the thin or thick film of the oxide superconductor. Since the amorphous deposited film is oxidized before heat treatment, Pb low in vapor pressure is converted to its oxide in this way, the vapor pressure of Pb is reduced, and the thin or thick film of the oxide superconductor having almost a single high-temp. phase is produced.

Abstract: PURPOSE:To easily generate a circular arc for production of a fillet curved surface where two curved surfaces are smoothly connected together in a designated radius by deciding first the 1st and 2nd surfaces and a plane which crosses these two surfaces. CONSTITUTION:A plane 8 passing through a point set on a line 7 piercing through the surfaces 1 and 2 is obtained together with the lines 9 and 10 crossing both surfaces 1 and 2. Then the lines 9 and 10 are moved by the same extent within the plane 8 and an intersecting point 13 is defined as the center of a circular arc. Thus a circular arc is obtained on both lines 9 and 10. In the same way, the circular arcs are generated with other points on the line 7. A fillet curved surface is obtained when those circular arcs are connected together. This generating procedure can be simply carried out by a computer.

Title: Synchronization system signal detector
Inventor: KANEKURA MASAO
IPC: H03D1/22
Filed: 1992-08-12
Abstract: PURPOSE:To easily reduce the size and cost of a device by using an analog switch capable of obtaining high integration and obtaining high output voltage. CONSTITUTION:A phase synchronizing system PLL sends a control signal phase- synchronized with an input signal inputted from an input terminal IN to an analog switch AS. A capacitor C1 is charged with input voltage only by a half period of the input signal through a resistor R, and in the remaining half period, a capacitor C2 is charged based upon the input voltage. When a time constant R.C1 is sufficiently large compared with the period of the input signal and impedance connected to an output terminal OUT is sufficiently large, the capacitor C1 is charged with DC voltage equal to the average value of the input voltage and the capacitor C2 is charged with twice the DC voltage. Namely when the input signal has the same phase as that of the control signal, voltage corresponding to twice the average value of the input voltage appears on the output.
