Filed: 1989-08-29
Abstract: PURPOSE:To carry out an inference process in a smooth and accurate way by treating the values of an inference subject and the subject serving as an intermediate hypothesis of an inference process as a single value (assembly) containing plural elements if the values of those subjects are collective and carrying on the inference. CONSTITUTION:When the knowledge treating the collective value is transferred to a knowledge base analyzing part 2 from a knowledge base 1, a collective type analyzing part 2a included in the part 2 decides the values enclosed in curly brackets as the collective ones and sends this to an inference mechanism part 3. The part 3 reads out a collective arithmetic/comparison library 4a so as to perform the collective operations of products and sums to the collective value via a library 4 as necessary during an inference using the knowledge treating the collective value or to compare the collective value with another collective value and the single value to take a specific element out of the elements of the collective value. Then the part 3 treats the collective value as a single value containing plural elements and carries on the inference. Thus the inference can be processed in a smooth and accurate way.

Filed: 1991-08-09
Abstract: PURPOSE:To obtain a powdery pollucite having low thermal expansion coefficient even in a low-temperature region by specifying Al2O3/SiO2 molar ratio and Cs2O/SiO2 molar ratio. CONSTITUTION:The pollucite powder is composed essentially of a pollucite phase and has an Al2O3/SiO2 molar ratio of 0.21-0.25 and a Cs2O/SiO2 molar ratio of 0.19-0.22 wherein 2-10mol% of the above Cs2O may be substituted with Li2O. The powder has low thermal expansion coefficient between room temperature and 1000 deg.C or above and gives a sintered compact having high density and high strength and, accordingly, it is useful as a material having high thermal shock resistance. The crystal phase of pollucite can be maintained even by varying the molar ratios within the above ranges. The powder can be produced by mixing alumina sol, silica sol and cesium salt at ratios to give a dehydrated mixture having nearly the same composition as mentioned above in terms of oxides and calcining the mixture e.g. at 900-1100 deg.C for 5-20hr.

A detected output of the system 1 is amplified by a TRQ1 and applied to a TRQ3 of a differential amplifier. On the other hand, the noise signal in the detected output of the receiving system 2 is amplified by a TRQ2, the output is extracted from an emitter of the TRQ2 so that the phase is opposite to the phase of the noise signal included in the collector of the TRQ1, the level is adjusted to the same as the level applied to the TRQ3 by a variable resistor VRL and applied to a TRQ4 of the differential amplifier. Thus, the noise signal of opposite phase is cancelled and only the objective signal is extracted.
