    摘要: An optical disc recording apparatus for recording information signals on an optical disc having an optical recording medium with a larger than normal thermal time constant, such as an organic dyestuff base material, by irradiating the disc with a recording light modulated by signals produced by eight/fourteen modulation of information signals, is disclosed. The apparatus includes a recording pulse forming unit for forming recording pulses from the eight/fourteen modulated signals, which recording pulses are of pulse widths shorter than the eight/fourteen modulated signals by a pulse width corresponding to the elongation from the regular length of a pit formed on the recording medium on the basis of the eight/fourteen modulated signals, and an optical head supplied with the recording pulses formed by the pulse forming unit for producing the light which has been pulse width modulated by the recording pulses.

    摘要: A known refrigerating system for a container is improved to include container wrong or abnormal condition diagnostic facilities. Such additional facilities include a container inside temperature detector, a container outside temperature detector, a control responsive to a wrong condition diagnosis instruction for operating an evaporator fan and an electric heater of the refrigerating system, and a wrong condition diagnostic device for diagnosing whether or not a wrong condition of the container is present on the basis of the temperatures detected by the respective temperature detectors after a predetermined period of operation of the evaporator fan and the electric heater. If the temperature detected by the container inside temperature detector has risen to a predetermined temperature or higher in relation to the temperature detected by the container outside temperature detector, the wrong condition diagnostic device diagnoses that the container is normal, but if the temperature has not risen to the predetermined temperature, the container is diagnosed to be abnormal.

    摘要: In a method for transmitting interleaved data, when the respective data blocks to be transmitted are interleaved and augmented by the error correcting parity codes before being transmitted on the transmission channel, a prescribed number of dummy data are provided between the respective data blocks so that the data block and the neighboring data blocks are not in the interleaving relation. In this matter, data addition, correction and substitution can be made easily for each data block or a group of blocks without influencing the error correction parity codes of the remaining block data.
