    Abstract: A process for forming contact material of an electrode comprises the steps of preparing chromium of which oxygen content is substantially reduced, forming a molten mixture of the chromium and copper, atomizing the molten mixture into fine particles to obtain Cu-Cr alloyed powder, compacting Cu-Cr alloyed powder under desired pressure, and sintering the compacted alloyed powder. The oxygen content of the chromium may be reduced until less than 0.1 wt %. In a course of the process, a metal having melting point lower then copper may be blended. The metal may be blended in Cu-Cr alloyed powder, or blended in the molten mixture of copper and chromium. Alternatively, the process further includes the steps of forming a second molten mixture of copper and a metal having melting point lower than copper, atomizing the second molten mixture into fine particles to obtain alloyed powder of copper and the metal, and blending Cu-Cr alloyed powder with the alloyed powder of copper and the metal. The metal may be selected from one or mixture of the metals consisting of bismuth, lead, tellurium, antimony and selenium.

    Abstract: A vacuum capacitor includes a fixed electrode, a movable electrode, a movable electrode shaft, a magnetic flux receiving unit, a magnetic flux generating unit and a capacitance control unit. The fixed electrode is formed from a plurality of electrode members in a vacuum casing. The movable electrode is formed from a plurality of electrode members arranged in gaps formed between the electrode members of the fixed electrode in the vacuum casing. The movable electrode shaft supports the movable electrode. Capacitance appearing between the movable electrode and the fixed electrode is varied by rotation of the movable electrode shaft. The magnetic flux receiving unit rotates the movable electrode shaft in the vacuum casing. The magnetic flux generating unit is located outside the vacuum casing and rotates the magnetic flux receiving unit by magnetic attraction. The capacitance control unit rotates the magnetic flux generating unit.
