Abstract: An electric motor system includes a battery, an inverter, an electric motor, a zero-phase switching arm and a control unit. The inverter converts DC power output from the battery into three-phase AC power and outputs the three-phase AC power to the electric motor. A rotor of the electric motor rotates by the three-phase AC power output from the inverter. A neural point of the electric motor is connected to the zero-phase switching arm. A zero-phase current flowing through respective windings of the electric motor is adjusted by switching of the zero-phase switching arm. By this means, in the electric motor system, torque is generated at the rotor also using the zero-phase current as well as a three-phase AC current flowing through the respective windings.

Abstract: There is provided a sputtering method in which abnormal discharging due to charge-up of a to-be-processed substrate is restrained and in which a good transparent conductive film can be formed on a to-be-processed large-area substrate. Out of a plurality of targets disposed side by side with, and at a predetermined distance from, one another so as to lie opposite to the to-be-processed substrate inside a sputtering chamber, electric power is applied, by alternately changing polarity at a predetermined frequency, to the targets that form respective pairs. Each target is thus alternately switched to anode electrode and cathode electrode. Glow discharge is thus generated between the anode electrode and the cathode electrode to thereby form plasma atmosphere, whereby each target is sputtered. During sputtering, electric power application to each of the targets is intermittently stopped.
