Abstract:
An apparatus for measuring electromagnetic characteristics includes a sample rod with a sample fixed to a lower part thereof, a helium 3 refrigerator, in which the sample rod is inserted, having a main pipe that forms around the sample rod a space that is cooled by helium 3, a device for supplying helium 3 to the helium 3 refrigerator, an inner tube portion, into which the main pipe is inserted, that supports at an upper part thereof the refrigerator, an outer tube that cools an outer periphery of the inner tube with helium, a liquid helium container that supplies liquid helium to the outer tube, and a device for measuring the electromagnetic characteristics of the sample.
Abstract:
An electrically conductive high-melting-point oxide light source that can be used in an oxygen-containing atmosphere includes a sintered oxide having as an essential constituent an oxide of an element selected from the group consisting of ruthenium, iridium, rhodium and rhenium. It is used an oxygen-containing atmosphere at a temperature of not less than 1700null C. A high-melting-point conductive paste includes particles of a sintered oxide having as an essential constituent an oxide of an element selected from the group consisting of ruthenium, iridium, rhodium and rhenium, and a binder and solvent. An exhaust gas filter includes a powdered sintered oxide having as an essential constituent an oxide of an element selected from the group consisting of ruthenium, iridium, rhodium and rhenium, the powdered sintered oxide being applied to and baked on, or formed into a heating element and attached to, a surface of a diesel engine exhaust gas filter of ceramic to form a heating element.
