The variable valve timing controller has an electric motor which rotates a phase converter. In addition, the present invention can acquire safety during the polymerization by insulating a main body from a substrate to which voltage is applied. A coating is deposited onto a plurality of substrates in a method for deposition that attracts ions within the plasma to the substrates and deposits a coating onto the substrates. The computer controls the protocol conversion module to simulate a keyboard to send keyboard commands to the device.
