In a liquid substance supply device, a three port two valve directional control valve is provided in a transfer line, and a substance container and the transfer line are connected together by a four port three valve directional control valve in such a way that the four port three valve directional control valve and the substance container can be removed from the transfer line as a unit. Furthermore, in a vaporizer, an orifice member is provided to surround the end portion of an internal conduit in which flows a mixture substance consisting of a gas and a liquid substance mixed therewith, and gas for atomization is spouted into a vaporization chamber through a gap defined between the internal conduit and the orifice member. Yet further, the temperature of a vaporization surface in the vaporization chamber can be controlled independently in correspondence with the nature of the liquid substance.

A metal electrode is formed on a substrate. The metal electrode includes a first layer, a second layer, and a third layer lying, from an outermost surface of the metal electrode toward the substrate, in this order. The first layer contains tin as a principal constituent and the second layer contains a metallic element which produces an eutectic reaction with tin, wherein the melting point of the first layer is higher than the melting point of the second layer. The third layer is an underlying metallic layer for the first and second layers.

A bolometer thin film having a high temperature coefficient of resistance (&verbar;TCR&verbar;) 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 Z CuO , 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&lE;y&lE;2, and x is a number satisfying 0.5y<x&lE;1.5&plus;2y. The bolometer has a temperature coefficient of resistance (&verbar;TCR&verbar;) higher than that of conventional bolometers. This bolometer is produced by forming a bolometer thin film by sputtering using a mixture of an oxide of Cu such as Cu O, CuO or a mixture of Cu O and CuO with an oxide of any of the elements represented by Z, or a complex oxide of these elements as a target.

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.
