Patent number: 6420318Abstract: Superconducting composite materials having particles of superconducting material disposed in a metal matrix material with a high electron-boson coupling coefficient (&lgr;). The superconducting particles can comprise any type of superconductor including Laves phase materials, Chevrel phase materials, A15 compounds, and perovskite cuprate ceramics. The particles preferably have dimensions of about 10-500 nanometers. The particles preferably have dimensions larger than the superconducting coherence length of the superconducting material. The metal matrix material has a &lgr; greater than 0.2, preferably the &lgr; is much higher than 0.2. The metal matrix material is a good proximity superconductor due to its high &lgr;. When cooled, the superconductor particles cause the metal matrix material to become superconducting due to the proximity effect. In cases where the particles and the metal matrix material are chemically incompatible (i.e.Type: GrantFiled: November 4, 1999Date of Patent: July 16, 2002Assignee: The Board of Trustees of the Leland Stanford Junior UniversityInventor: Matthew J.

Patent number: 6372362Abstract: A method for forming a composite vapor-deposited film one side of which suitable for vapor-deposition on a phosphor surface of a CRT, such as a color television picture tube, has high light reflectivity, and the other side of which has a property to absorb radiant heat, and a composite vapor-deposition material suitable for vacuum deposition are disclosed. The composite vapor-deposition material has a high vapor-pressure metal envelope and a low vapor-pressure metal in the core region of the envelope. Low vapor-pressure metal powder should preferably be dispersed and held by high vapor-pressure metal powder in the core region. Vacuum deposition using this composite vapor-deposition material yields a composite deposited film having a composition comprising almost 100% of the high vapor-pressure metal formed in the initial stage of evaporation, and a composition comprising 100% of the low vapor-pressure metal formed in the final stage of evaporation.Type: GrantFiled: March 24, 2000Date of Patent: April 16, 2002Assignee: Hitachi Metals, Ltd.Inventors: Shinji Furuichi, Shigetoshi Takashima
