Title: Josephson mixer
Inventor: FUKUMOTO YOSHITO
IPC: H03D9/06
Filed: 1991-04-15
Abstract: PURPOSE:To form a Josephson element, a coil, a capacitor and a resistor or the like being components of a superconducting Josephson mixer onto a same board in a monolithic way. CONSTITUTION:There has been a problem in a conventional mixer that each signal is attenuated via lead wires of each component or an amplitude and the S/N of an intermediate frequency signal are not sufficiently taken because the mixer is of multi-chip structure in which a Josephson element is formed on a substrate and other components are mounted externally. In order to solve the problem, the Josephson element 2 and each component are formed on the same substrate in a monolithic way to minimize a signal loss and a signal introduction section is formed by a strip line type resonance circuit to maximize the mixing capability at a maximum efficiency, then the intermediate frequency signal with the excellent S/N is outputted. Moreover, an IF output section is formed by a resistor impedance matching circuit to realize the Josephson mixer suitable for the use at a high frequency band.

Abstract: PURPOSE:To perform the laser oscillation efficiently thereby enabling the life of the title capacitor to be prolonged by a method wherein an insulating case is provided between multiple opposite electrodes so as to effectively avoid the along-surface discharge between electrodes for eliminating a resin mold. CONSTITUTION:The title capacitor is composed of a cylindrical insulating case 38 with its bottom surface closed, electrodes 32a, 32b and a dielectric 30. A disc type dielectric 30 is contained on the bottom surface in the case 38 while a disc type electrode 32a is arranged in contact with the surface side of the dielectric 30. Besides, a flat plate type electrode 32b is arranged opposite to the electrode 32a outside the bottom surface to supply high voltage. In such a constitution, the high breakdown strength capacitor can effectively avoid the along-surface discharge between the electrodes 32a, 32b by the case 38 thereby enabling itself to be miniaturized due to the elimination of a resin mold. Besides, the laser medium gas does not oscillate the case 38 thereby enabling the life of the capacitor to be prolonged. Furthermore, the breakdown strength can be augmented due to the shape of the case 38 near the open end.
