    摘要: The present invention provides an error correction apparatus and an error correction method, which does not execute unnecessary syndrome operation and operation processing subsequent to the syndrome operation. A format interface 10a judges whether an uncorrectable error is included in parallel with demodulation of received data, and outputs an error correction incapability detection signal when the uncorrectable error is included. The error correction circuit 20a executes decoding of the error correction, including syndrome operation, for demodulated data from the format interface 10a, suspends the syndrome operation when the error correction incapability detection signal is input, and terminates the error correction.

    摘要: The tubular die of a centrifugal casting device of GNo.30 or above is employed suitably and powder is introduced while rotating, and an outer tubular body composed of that powder is provided. Subsequently, molten is introduced to the inner circumferential wall side of the outer tubular body while sustaining rotation of the tubular die thus forming an inner tubular body. The outer tubular body functions as a cooling metal (chiller) when the molten is cooled and solidified. In place of the outer tubular body composed of the powder, molten may be used for forming an outer tubular body or an outer tubular molding molded previously into tubular shape may be employed.
