A speech signal is input to an excitation signal generating section, a prediction filter and a prediction parameter calculator. The prediction parameter calculator calculates a predetermined number of prediction parameters (LPC parameter or reflection coefficient) by an autocorrelation method or covariance method, and supplies the acquired prediction parameters to a prediction parameter coder. The codes of the prediction parameters are sent to a decoder and a multiplexer. The decoder sends decoded values of the codes of the prediction parameters to the prediction filter and the excitation signal generating section. The prediction filter calculates a prediction residual signal, which is the difference between the input speech signal and the decoded prediction parameter, and sends it to the excitation signal generating section. The excitation signal generating section calculates the pulse interval and amplitude for each of a predetermined number of subframes based on the input speech signal, the prediction residual signal and the quantized value of the prediction parameter, and sends them to the multiplexer. The multiplexer combines these codes and the codes of the prediction parameters, and send the results as an output signal of a coding apparatus to a transmission path or the like.

A method for coding a motion vector using a 2-dimensional minimum bitrate predicting technique is disclosed. A mode information (MODE) commonly adopted to the factors ‘X’ and ‘Y’ are transmitted to thereby reduce its transmission burden by using the two-dimensional minimum bitrate predicting technique, so that a coding efficiency of a motion vector can be improved. In addition, the two-dimensional MVD information coding method is proposed for the low transfer rate mobile image which is very small and has very small motion, so that even if a distribution characteristic of the MVD information is changed according to the minimum bitrate prediction, a coding efficiency of a major motion vector can be improved.

A ratio (Nc/Lc), in a condenser core portion, of the number of louvers to a width of a condenser cooling fin, and a ratio (Nr/Lr), in a radiator core portion, of the number of louvers to a width of a radiator cooling fin satisfy that the ratio in one core portion, out of the condenser and the radiator core portions, a required radiation amount of which is larger than that of the other core portion is larger than the ratio in the other core portion. Thus, in the core portion having a small required radiation amount, the number of louvers relative to the width of the cooling fin is small thereby decreasing the heat transfer ratio. However, by this, the air flow resistance in this core portion decreases thereby increasing an air flow amount. Thus, the radiation amount of the core portion of which required radiation amount is large increases.
