By optimising the Al, Si, Mn, N and S added components in this way, the distribution density of coarse inclusions is increased, thereby making it possible to improve crystal-grain growth properties and domain wall mobility and so produce the highest grade of non-oriented electrical steel sheet having superior magnetic properties, low hardness, and superior customer workability and productivity.

    摘要: A communication system communication system includes a transmitter and a receiver. The transmitter inverts multiple bits of first transmission data, serializes the first transmission data to generate second transmission data, and provides the second transmission data to communication channels, in response to an error signal. The receiver inverts multiple bits of first reception data provided from the communication channels, parallelizes the first reception data to generate second reception data, and generates the error signal based on the second reception data, in response to the error signal.
