Abstract:
An apparatus for providing a deposition on a plurality of substrates, including,a cylindrical stator having a periphery and having teeth on its periphery,a plurality of planets each constructed to support one of the substrates and each rotatable relative to the stator relative to and each having a periphery and having on its periphery a plurality of teeth in mesh with the teeth on the periphery of the stator, each of the planets being constructed to support an individual one of the substrates for rotation with such planet,means energizable to rotate the planets,means for pressing the planets against the stator,means disposed on the stator at a position displaced from the teeth and in coupled relationship with the planets for providing a braking action on the planets to provide an instantaneous interruption in the rotation of the planets relative to the stator when the energizable means becomes de-energized, anda gun disposed relative to the planets for producing a deposition on the substrates in accordance with the rotation of the planets when the substrates are disposed on the planets, wherein the braking means constitutes an O-ring disposed on the stator at a position displaced from the teeth on the stator and the teeth on the planets and wherein the planets press against the O-ring on the stator to distort the O-ring at such pressing positions.
