Abstract: In a remote control communication system, a transmitting apparatus transmits operation information, which includes switch information indicating the type of the switch and operation duration information, to a receiving apparatus in a vehicle. If another operation is again carried out on any operation switch, the transmitting apparatus transmits present operation information with the operation information transmitted previously. A receiving apparatus transmits the operation information and reception duration information to a control apparatus in the vehicle. Similarly, if other operation information is received again, the receiving apparatus transmits the other operation information with the previous operation information.

Abstract: A conductive layer of a conductive member for an image-forming apparatus is composed of a conductive polymer composition containing an ionic-conductive addition salt. The conductive polymer composition has a continuous phase and one or more uncontinuous phases including at least one first uncontinuous phase. The continuous phase and the uncontinuous phase form a sea-island structure. A salt capable of dissociating into cations and anions is unevenly distributed to the first uncontinuous phase. A polymer composing the first uncontinuous phase has a higher degree of affinity for the salt capable of dissociating into cations and anions than a polymer composing the continuous phase to prevent the salt (or the cations, the anions) from shifting out of the first uncontinuous phase or out of the polymer composition. The conductive polymer composition can contain melamine cyanurate so that it is flame-retardant.
