摘要： A method of manufacturing a superconductive coil by means of explosive compaction. A wire formed of silver having a superconductive oxide powder charged therein is formed into a coil. The coil is placed within a cylindrical vessel, into which a pressure medium is charged. Explosive compaction is carried out to cause the compaction of the coil through the cylindrical vessel and the pressure medium and hence densify the coil. The compacted coil is heat-treated in an air or oxygen atmosphere. The resulting superconductive coil possesses high critical electric current density. Advantageously, the coil is mounted on a mandrel axially extending therethrough, and placed together with the mandrel into the cylindrical vessel, before explosive compaction.

摘要： A measurement unit for tensile or compressive stress can includes a CCD camera for detecting an interference light, the interference light being formed with a measurement beam from a measured region and a reference beam from a reference mirror. A first objective lens can have the reference mirror. An image processing apparatus can measure the three-dimensional shape of the measured region from the position of the first objective lens at which the interference light provides the maximum contrast and can measure the distance between two gauge points on the basis of the three-dimensional shape. When strain is generated on a micromaterial, the strain against the measured tensile stress is measured on the basis of the tensile stress and the distance between the two gauge points.
