    摘要: A logical type language data processing method which includes making a plurality of different application programs each using a predicate type fact database and/or a predicate type rule database; inputting a predicate type question with respect to the application programs to process data by unification and back tracking processes; making and storing a common predicate type fact database which is used commonly by the different application programs; putting a symbol to predicates of the different application programs to indicate that the predicates with the symbol are common type predicates which should use the common predicate type fact database; and accessing the common predicate type fact database if any of the predicates with the symbols is read out during execution of the application programs.

    摘要: A method for generating rules for an expert system for use in controlling operation of a plant is provided. In this method, an analysis by Quantification Theory I or II is made on operating data offered by an operator in a plant, whereby the relationship between the operator's manipulated value of operating data and the operator's controlled value of operating data is analyzed. The results of the analysis are then integrated to generate a rule for controlling operation of the plant.

    摘要: A multi-level quadrature amplitude modulation and demodulation system includes a first exchange circuit for cyclicly exchanging input digital signals and for outputting exchanged signals to D/A converters. The D/A converters provide analog signals to a QAM modulator which produces a modulated signal. In the receiver side of the system, a QAM demodulator demodulates the modulated signal to produce analog signals which are converted to digital exchanged signals by A/D converters. The digital exchanged signals are exchanged in a manner which is the reverse of that of the first exchange circuit to provide output digital signals on output terminals which respectively correspond to the input terminals. By cyclicly exchanging the input signals in this manner, the transmission quality for each of the input signal channels is maintained equal.
