Abstract: A bolometer thin film having a high temperature coefficient of resistance (|TCR|) is produced in a simple and easy production process to provide a highly sensitive infrared sensing element. The invention provides a bolometer using a thin film of an oxide represented by ZyCuOx, wherein Z is one or more alkaline earth metals, one or more rare earth element selected from yttrium and lanthanide elements, one or more elements belonging to Period 5 or Period 6 of the Periodic Table selected from bismuth, lead, thallium, mercury, and cadmium, or potassium or sodium, y is a number satisfying 0≦y≦2, and x is a number satisfying 0.5y<x≦1.5+2y. The bolometer has a temperature coefficient of resistance (|TCR|) higher than that of conventional bolometers.

Abstract: A bolometer thin film having a high temperature coefficient of resistance (|TCR|) is produced by simple and easy production process steps to thereby provide a highly sensitive infrared sensing element. The invention provides a bolometer using a thin film of an oxide represented by ZyCuOx, wherein Z is one or more of alkaline earth metals, one or more of rare earth elements selected from yttrium and lanthanoid elements, one or more of elements belonging to Period 5 or Period 6 of the Periodic Table selected from bismuth, lead, thallium, mercury and cadmium, or potassium or sodium; y is a number satisfying the following condition: 0≦y≦2; and x is a number satisfying the following condition: 0.5y≦x≦1.5+2y. The bolometer has a temperature coefficient of resistance (|TCR|) higher than that of conventional equivalents.

Abstract: A method for manufacturing an infrared ray detector element utilizing a bolometer thin film having Bi1−xAxMn1O3 (element A being at least one element selected from a rare earth metal or an alkaline earth metal, 0≦x<1) as a main component. The method comprises a step of forming an oxide thin film having a metallic composition of Bi:A:Mn=1−x:X:1 by sputtering at a substrate temperature of equal to or above 100° C. and less than 500° C. within a gas atmosphere of containing oxygen or ozone. The second step is applying a heat treatment to the oxide thin film within a gas atmosphere containing oxygen or ozone to reduce the volume resistivity of the oxide thin film to a level at which an infrared ray detector circuit can operate. Thus, the bolometer having Bi1−xAxMn1O3 as a main component can be functioned as a bolometer and an infrared ray detector element of a high detectivity can be put in mass-production.

Abstract: A compound superconducting wire comprising a matrix of CuX alloy and a multiplicity of Z.sub.3 X filaments embedded in the matrix in a spaced relationship so as not to come into contact with each other wherein X is Sn or Ga and Z.sub.3 X is Nb.sub.3 Sn or V.sub.3 Ga. In a precursor, therefore, a multiplicity of filaments of a base metal material Z such as Nb are arranged in a Cu base metal matrix concentrically in layers around a center core of a base metal material X such as Sn, in which the spacing between any adjacent filaments arranged in a former boundary region of an .epsilon.-phase bronze layer having a certain radius from the center produced when the precursor is preheat-treated at a temperature of 300.degree. to 600.degree. C. is made larger than the spacing between any adjacent filaments arranged in the other matrix regions.

Abstract: A process for preparing a superconducting wire having improved superconducting characteristics in shortened period of time at a reduced cost, which comprises the steps of forming a plurality of holes in each of Cu base metal plates, stuffing the plates in a supporting container to form a stacked body of the plates with their holes aligned with each other, stuffing a superconductor or a material convertible into a superconductor by a heat treatment into the resulting through-holes of the stacked body, evacuating and sealing the supporting container to form a composite billet, and processing the composite billet in a usual manner to give a superconducting wire.
