摘要： PURPOSE:To make the title material superior in workability and ligher and reduce its thermal stress by a method wherein a volume content rate of a carbonic fiber made of a composite metal is specified with aluminum as a mother phase, and the carbonic fiber is two-dimentionally arranged without any order in the direction of the mounting face of electronic components and in a layer- like manner in the face direction perpendicular to the mounting face of the electronic components. CONSTITUTION:Without aluminum or an aluminum alloy as a mother phase, a carbonic fiber is made of dispersed composite metals, a volume content rate of the carbonic fiber is 0.15 to 0.55, and the carbonic fiber is two-dimentionally arranged without any order in the direction of a mounting face of electronic components and in a layer-like manner in the face direction perpendicular to the mounting face of the electronic components. As a result, differences of a heat expansive coefficient of a semiconductor or a package can be made small, and a thermal stress to be loaded at a junction of a case material with the semiconductor or the package can be restrained to a small value.

摘要： PURPOSE:To obtain an oxide superconductor having a critical current density comparable to that of the conventional one and a higher critical temp. than the conventional one by heat treatment at a low temp. for a short time, by melting powdery starting materials for an oxide superconductor by heating, rapidly cooling the resulting melt under blown oxygen to form a bulk and heat treating the bulk in an oxidizing atmosphere. CONSTITUTION:Oxides, nitrates or carbonates which exhibit superconductivity after heat treatment in an oxidizing atmosphere are melted by heating, e.g., with laser beams 3. The resulting melt 2 is rapidly cooled under blown oxygen 5 to form a bulk and this bulk is heat treated in an oxidizing atmosphere.
