Title: Oxide-based covering member for superconductor
Inventor: KORIYAMA SHINICHI
IPC: C01G3/00
Filed: 1987-11-30
Abstract: PURPOSE:To make it possible to use an inexpensive ceramic base board while preventing elements from moving from the base board to a thin film of superconductor by arranging an intermediate layer of either a single metal or metallic compound of Ti, V, Cr, and Mn between the thin film and the base board. CONSTITUTION:A perovskite type oxide-based superconductor is arranged on a ceramic board made of alumina or the like. An intermediate layer is disposed between the base board and a thin film of superconductor, with the intermediate layer being made of at least one metal or metallic oxide or nitride chosen out of Ti, V, Cr, and Mn. The arrangement of the intermediate layer prevents, when forming the superconductive layer on the base board, alumina in the base board from dispersing into the film, from causing element substitution with ions in the film composition, and from deteriorating the superconductivity. The intermediate layer itself on the other hand causes no adverse effect on the superconductive film. As a result, an inexpensive ceramic base board can be used to reduce cost rather than using more expensive boards than this.

Abstract: PURPOSE:To make a dot whose grid and anode reach an operating potential illuminate with simple electrode structure by setting the potential of a grid adjacent to a grid which reaches the operating potential to >=1.5 times as high as a normal cutoff potential. CONSTITUTION:An electron emitted from filament 4 is accelerated to a grid 3a by the operating potential Eco of a grid 3a.
