2067824 9105643 PCTABScor01 Confident that, when cracks occur in a piece of timber due to the heat treatment of the timber, an acoustic emission (AE) should occur, an effective AE signal directly involved with the cracks is discriminated and detected, and, in addition to this, the total (integrated) number of events and the rate of occurrences of AE are monitored while the drying treatment process and the high temperature treatment process are discriminated to thereby put all above evidences together to predict cracks occurring during the processes of the drying treatment and the high temperature treatment, whereby the temperature and humidity are controlled on the basis of the predicted information to thereby control the atmosphere such that the cracks will not occur. Furthermore, in that case, the timber is impregnated with a specific organic solvent medium to conduct the impregnating treatment where the water and the heat react chemically with each other, whereby the interior of the piece of timber is plasticized and the cracks due to the heating treatment are prevented from occurring and the brittleness in the quality of timber due to the high temperature treatment is greatly bettered, thus improving the workability of the timber.
