An inner magnetic shield is provided that reduces mislanding lengths due to electron beam distortion caused by external magnetic fields such as terrestrial magnetism, thereby reducing the occurrence of drifted or uneven color throughout an entire display screen. The inner magnetic shield is of a tube with a plurality of side surfaces, and is provided with at least one skirt ( ) that extends to the vicinity of a spanning member ( ) at a location where the inner magnetic shield is not in contact with a holding member ( ). The skirt ( ) is magnetically coupled with the spanning member ( ).

Cathode ray tube

A cathode ray tube including an internal magnetic shield in the shape of a hollow rectangular frustum including two long sides opposite to each other and two short sides opposite to each other, having an opening at its top and bottom attached to a mask and a frame. Each long side has a long side extension at a horizontal center located at the top of the internal magnetic shield where an electron beam enters the internal magnetic shield. The long side extensions enable the magnetic shield to reduce the deviation of an electron beam within the magnetic shield caused by an external magnetic field such as that caused by terrestrial magnetism.

Cathode ray tube for achieving small electron beam landing deviation

Excellent films of a high Tc superconductor are easily produced on metal coated substrates at a temperature below 700.degree. C. These metal buffer films are made of Pt, Au, Ag, Pd, Ni or Ti. The film superconductivity is significantly improved by the metal buffer layer. Since it is easy to form this metal coating on a substrate, the invention can increase the potential number of usable substrates such as fibers, amorphous solids or semiconductors.

Superconductor

A manufacturing method for the thin film superconductor is disclosed in which photons having energies larger than ultraviolet rays are irradiated to the thin film superconductor on or after formation of the thin film. Further, manufacturing methods for superconductive magnetic memory, Josephson device and superconductive transistor are disclosed.

Method for manufacturing thin film oxide superconductors and

A Josephson device, comprising a junction formed by forming the first layer-shaped oxide superconductor thin film including a plurality of Cu-O layers on a substrate, a barrier layer thereon and the second layer-shaped oxide superconductor thin film on the barrier layer. The Josephson device according to the present invention is manufactured by forming the first layer-shaped oxide superconductor thin film on a substrate, forming a barrier layer in the same vacuum chamber, defining patterns to said barrier layer and said first layer-shaped oxide superconductor thin film, forming an interlayer insulating film on said barrier layer, removing said interlayer insulating film in a region serving as a junction, effecting exposure to oxygen plasma, forming the second layer-shaped oxide superconductor thin film in contact with a part of the surface of said barrier layer and defining patterns to said second layer-shaped oxide superconductor thin film.
