That is, while the call is bridged to the first endpoint, a bridge is added between the first telephone line and the second endpoint.

Abstract: Perovskite materials having magnetoresistive effect under the influence of an electric field can be employed in the construction of nonvolatile solid state electro-optic modulator. These materials display nonvolatile changes in electrical resistance and reactant when subjected to an electric field.

The nonvolatility of these materials is exploited in the construction of nonvolatile display and nonvolatile solid state electro-optic modulators such as waveguide switch or phase or amplitude modulators.

Abstract: The present invention discloses a novel ferroelectric transistor design using a resistive oxide film in place of the gate dielectric. By replacing the gate dielectric with a resistive oxide film, and by optimizing the value of the film resistance, the bottom gate of the ferroelectric layer is electrically connected to the silicon substrate, eliminating the trapped charge effect and resulting in the improvement of the memory retention characteristics. The resistive oxide film is preferably a doped conductive oxide in which a conductive oxide is doped with an impurity species. The doped conductive oxide is most preferred to be In2O3 with the dopant species being hafnium oxide, zirconium oxide, lanthanum oxide, or aluminum oxide.
