A method and apparatus for generating gas for a processing system is provided. Oil is effectively separated from a refrigerant discharged from the compression part, thereby being prevented from leaking outside the casing. A first sub-line and space pattern in the first region comprises a space of a dimension less than achievable by lithographic processes alone. In the standby mode, a relatively small amount of electrical power is supplied to the traction electric motor to cause a vibration of the motor to alert a driver that the vehicle is ON in the standby mode and is ready to be driven. The intermediary API may determine if the request is non-terminating, and if all criteria are met, may provide presence data to the requesting client.
