An environmental control system for an aircraft may be employed to regulate temperature of air entering a cabin of the aircraft. The enclosure end of the remote control cord is connected to an electrical circuit in the enclosure which connects an electrical power source to receptacles mounted to the enclosure. In particular, the carbon-containing silicon oxide film is plasma etched using a plasma generated from a source gas comprising NH3 and CxFy. A web is coupled to the first and second planar surfaces such that the first and second planar surfaces are spaced apart from and parallel to each other. A conveyance speed of the recording medium at the nipping position is faster than that at the secondary transfer position. The difference in ionization potential between a host material and a hole transport layer and the difference in electron affinity between a host material and of an electron transport layer are set in a favorable range for all organic light emitting devices which emit light of different colors.
