Abstract: The present invention relates to a distribution aiding system, a distribution aiding server, a distribution aiding method, and a distribution aiding program capable of selling articles without individual trading conditions being known to a maker, other users or other dealers, and is so configurated that a user retrieves or selects a necessary article, the user registers order information according to the selected article, and a dealer in charge of the user registers order-acceptance condition information to be added to the order information, and notifies the user of the order-acceptance condition information.

Abstract: A construction of a filter 170 that allows air stream from a blower fan 120 to pass through a heat exchanger 130 arranged adjacent to the blower fan 120 after its flowing direction is changed by about 90 degrees. The filter 170 is disposed on the front surface of the heat exchanger on the upstream side of the air flow and has a construction such that airflow resistance of the filter gradually changes with respect to the flow velocity of air passing through the filter and in this way, flow velocity distribution of air passing through the heat exchanger becomes uniform. In this case, a fold pitch P of folds of the filter that is folded or a peak height h of the folds is changed in a plurality of steps or without any steps.

Abstract: In order to increase both the weighing accuracy and the weighing speed of a weighing apparatus, a delta.multidot.sigma analog-to-digital converter (4) having a cut-off frequency higher than that of an analog filter (3) is connected with the output of the analog filter (3). Also, in order to perform a quick drift correction of an amplifier (2), the analog filter (3) is selectively switchable so as to perform a filtering function during a weighing mode and to perform a buffering function during a correction mode correcting means (52) is provided for storing the digital signal from the delta.multidot.sigma analog-to-digital converter (4) as a drift signal (df) during the correction mode and for providing a corrected digital weight signal (d2) by subtracting the drift signal (dr) from the digital weight signal (d1) obtained from the delta.multidot.sigma-type analog-to-digital converter (4) during the weighing mode.
