Inventor: NAKAGAWA MASAHIRO
IPC: C30B29/42
Filed: 1987-08-25
Abstract: PURPOSE:To obtain the titled single crystal through growth without the seed crystal becoming thinner or fading away, by immersing the whole seed crystal in the liquid sealer layer when said seed crystal is immersed in a melt to carry out seeding. CONSTITUTION:A seed crystal is immersed in a melt provided with a liquid sealer layer thereon to carry out seeding followed by lifting said seed crystal to effect crystal growth from the melt.

IPC: H01L39/12
Filed: 1987-08-26
Abstract: PURPOSE:To semipermanently maintain the superconductivity of an oxide superconductor by preserving the superconductor in a waterproofing medium substantially free of water. CONSTITUTION:The oxide superconductor (e.g., a Y-Ba-Cu-O based superconduc tor or an La-Sr-Cu-O based superconductor) is preserved in a waterproofing medium substantially free of water.
