Abstract: A processor-implemented method of interlinking a first video conference system and a second video conference system for combining and transmitting voice signals of a plurality of users in a video conference system interlinking apparatus including a plurality of video sharing units including receiving second video conference data of a plurality of users from the second video conference system and transmitting voice data including combined voices of two or more users, among the transmitted second video conference data, through a single one of the plurality of video sharing units.

Abstract: In a sputtering device which has a small rotatable magnetron (30) arranged opposite a target 16, the magnetron (30) has a first magnet band (44) and a second magnet opposite a target 16, the magnetron (30) has a first magnet band (44) and a second magnet a greater total magnetic flux. Some of the lines of magnetic flux from the second magnet band (42) pass through the first magnet band (44) and terminate at the second magnet band (42). The remaining lines of magnetic flux from the second magnet band (42) form a magnetic flux loop that encloses the first magnet band (44) and that terminates at the second magnet band (42). The outer band is preferably in an oval shape having a minor axis no smaller than 0.8 of the major axis, and more preferably in a circular shape.
