Properties of Outputs

The properties of light, medium, and heavy oils distilled from pyrolysis oil. are shown in Table 26.7. 

In Table 26.8, the properties of the residue are also shown. It is notable that aluminum arising from laminated material and foil, and terephthalic acid from PET materials are dominant. The chlorine in the raw fluff transferred some 2.4% or so to the residue [3].

The direct transformation from the output pattern to the taste quality was performed here as one trial of expressing the actual human sensation using the output electrical pattern. A similar trial was done for evaluation of the strengths of sourness and saltiness, which will be mentioned later. These two trials depend on the utilization of simple transformation equations by extracting typical properties of output patterns. This method is effective if some data on sensory tests, using humans as a standard, can be obtained to compare with the sensor outputs. However, the expressions for the tastes of beer are obscure because they are not described by the five basic taste qualities. The purpose of the application of the taste sensor is also to express these kinds of obscure terms of human sense in scientific terms.
