Title: Origination monitoring circuit
Inventor: ARAI TOSHIO
IPC: H04M3/18
Filed: 1985-07-10
Abstract: PURPOSE:To eliminate circuit noises and electric erosion by using an N gate as one of the 2nd and the 4th current driving switch elements and a P gate as the other, and driving the latter by a positive-potential driving circuit and turning the 1st and the 2nd element on and the 3rd and the 4th elements off during origination monitoring operation. CONSTITUTION:Gates of current driving switches S2 and S4 use N gates and gates of current driving switch elements S1 and S3 use P gates; and the switch elements of the N gates are driven by negative-potential driving circuit D2' and D4' and the switch elements of the P gates are driven by positive-potential driving circuits D1 and D3. When origination is monitored, the switch elements S1 and S2 are turned on and the switch elements S3 and S4 are turned off. Consequently, the driving or off driving currents of the polarity inverting switches S2 and S4 flow to a power source VB through the driving circuits D2' and D4', so there is no noise generated to adjacent circuits. The inverting switch S2 is the gate, so it is so driven as to flow a current to a negative voltage VB and the potential of a speech line LB rises to the plus side in the origination monitoring state, thereby eliminating electric erosion.

Title: Grain boundary josephson junction and manufacture thereof
Inventor: ENOMOTO YOICHI
IPC: H01L39/22
Filed: 1991-06-21
Abstract: PURPOSE:To limit the number of grain boundary junction in a superconducting circuit by providing an electrode region having high critical current density made of an oxide superconductor thin film, and a tunnel junction made of a crystal grain boundary having low critical current density. CONSTITUTION:A superconducting polycrystal thin film 2 on a polycrystalline substrate 1 is formed of a plurality of crystalline grains 3, and a grain boundary bonds are formed at the grain boundaries 4, 5. In a structure of the junction, only a critical current density of the one junction is suppressed to a lower JL than a value JH of other grain boundary. This equivalent circuit is a series connection of the junctions. In current-voltage characteristics, if a current density is smaller than the JL, a superconducting current flows. If it exceeds the JL, one junction is varied to a voltage state, and continued until it exceeds the JH. When the current is reduced from this state, the current-voltage characteristics become a hysteresis. If the current exceeds the JH, other junction is shifted to the voltage state and the same operation as that of a single Josephson tunnel junction is performed until the current density exceeds the JH.
