In a network in which a plurality of ECUs are connected to one another with a common bus, one or more slots are allocated to each ECU in advance, and the plurality of ECUs cyclically transmit messages in an order prescribed in relation to the slots. When each ECU transmits the message related to one slot, each ECU creates and transmits a message including data to be transmitted to other ECUs, and information representing respectively a success/failure of the message reception related to other slots. Each ECU checks information of ACK field included in a message received during one cycle from message transmission related to one slot to a next message transmission related to said one slot. When the message related to one slot is not accurately received by the other ECUs, retransmits the message in the next transmission related to said one slot.

Communication system and communication apparatus

A connector for communication contains a connecting section, which is connected to communication line; and a network controller, which is connected internally to the connecting section, interprets a designated protocol and controls communication; and a transceiver, which makes possible transmission and receipt on the physical layer of the communication line.

Connectors transmitting/receiving an input/output signal as a communication signal, communication harness with the connectors, and the communication system with the connectors

A superconducting cable according to the present invention includes a former, a superconducting conductor layer formed around the outer circumference of the former, an electric insulating layer formed around the outer circumference of the conductor layer, a shield layer formed around the outer circumferential of the insulating layer, and a normal-conducting metal layer formed between the insulating layer and the shield layer. The normal-conducting metal layer existing inside shield layer has an inductance greater than that of the shield layer, which can suppress a rise in temperature in the event of accidents such as short-circuits, and also can reduce AC losses since currents flow through shield layer during the passage of normal currents.
