  • Publication number: 20120116596
    Abstract: The present invention comprises a flow rate sensor part and control valve; a calculation part that performs a proportional calculation on a deviation between a flow rate measurement value and setting value to calculate a feedback control value for the flow rate control valve; and an opening level control signal output part that generates an opening level control signal on the basis of the feedback control value to output the opening level control signal to the flow rate control valve. A gain value to be multiplied by the deviation is calculated by using a function that, in a predetermined period after the time point when the flow rate setting value decreases by a predetermined amount or more, calculates a larger value as a calculation value obtained by using a variation between the flow rate setting value before the decrease and a flow rate setting value after the decrease decreases.

  • Patent number: 7957171
    Abstract: Associative memories capable of outputting multiple reference data close to search data are provided. A memory array compares each of the multiple reference data with the search data in parallel and generates multiple comparison current signals representing the result of the comparison. A WLA converts the multiple comparison current signals into voltages. During the first cycle, the WLA detects the lowest voltage among the voltages as Winner and detects the remaining voltages as Loser. After the second cycle, based on feedback signals, the WLA detects all the voltages other than a voltage detected as Winner during the last preceding cycle, and detects the lowest voltage among the detected voltages as Winner and detects the remaining detected voltages as Loser. The WLA repeats these operations k times.
