摘要： A pressure sensitive conductor comprising an elastomer containing from 3 to 40% by volume of electrically conductive magnetic particles, which particles are dispersed in the elastomer so that high-sensitivity pressure sensitive conductor portions and insulator portions or low-sensitivity pressure sensitive conductor portions are both present therein. A method of manufacturing the pressure sensitive conductor comprises forming a sheet of a mixture containing electrically conductive magnetic particles in an elastomer, and subjecting the sheet to the action of magnetic fields before or during cross linking, thereby allowing the conductive magnetic particles to be uniformly dispersed in the sheet in a selected pattern.

摘要： To obtain a high-purity aluminum fraction from aluminum containing both eutectic impurities and peritectic impurities, the contents of these impurities in the original aluminum are reduced by melting the original aluminum to obtain molten aluminum, adding boron to the molten aluminum, and rotating a cooling body as immersed in the boron-containing molten aluminum while introducing a cooling fluid to the interior of the body to crystallize high-purity aluminum on the surface of the body. The peritectic impurities react with the boron to form metallic borides, which are centrifugally forced away from the cooling body by the rotation of the body without being incorporated into the aluminum crystallized on the surface of the body. The eutectic impurities are removed from the crystallized aluminum on the surface based on the principle of segregation.
