摘要： PURPOSE:To make it possible to industrially and efficiently produce high quality high- temperature heat-treated material by a method wherein crack of wood is foreseen by information-processing the signals of acoustic emission (AE) and high-temperature heat treat ment is performed under a condition that its atmosphere is controlled so as not to develop cracks in wood or the like by using temperature and humidity as operating factors on the basis of foreknowledge information. CONSTITUTION:AE is detected in the form of electric signals and cracks of wood or the like is foreseen by comparing data with reference values. For example, AE, the amplitude of which is 1 V or above with the amplification factor of 80 dB within one minute, is recorded. When the cumulative number of event exceeds the reference value or the amplitude exceeds the reference value, cracks are judged to enter warning region, resulting in actuating a steam pouring section so as to pour a large amount of steam in a heat treatment chamber in a short period of time in order to adjust the humidity in the heat treatment chamber. At the same time, the temperature in the heat treatment chamber is adjusted by controlling the actuation of a heating section so as to perform high temperature heat treatment by controlling atmosphere in order to maintain the conditions, under which no AE generates from the wood or the like or AE signals generated have values below the predetermined reference value in order to prevent cracks from developing in the wood. Thus, high quality high-temperature heat-treated material can be efficiently produced.

摘要： PURPOSE:To prevent wood or the like from cracking at the time of drying by sensing AE generated upon variation of a wood structure as a signal, information-processing the signal to presume crack of the wood, and heating it with temperature and moisture as operation factors. CONSTITUTION:Various vegetable wood or the like such as log, wood material, bamboo, etc., is immersed in organic impregnant of oxyethers such as polyethy lene glycol, methyl cellosolve, etc., polyvalent alcohols, phenols, natural rubber or synthetic rubber, or combination thereof, and thermally chemically reacted. An AE sensor is mounted on the immersed wood, AE generated upon variation of wood structure is sensed as a signal, the signal is information-processed to presume crack of the wood, heat treated at 100 deg.C or lower under normal pressure while controlling the atmosphere to eliminate crack of the wood with temperature and moisture as operation factors based on presumption information to be dried. Even in a drying step, the AE signal is observed to always grasp the advancing state on the way of drying of the wood.

摘要： PURPOSE:To carry out quickly impregnation without unevenness in an optional range by making cell cavities and the inside of cell cavities communicated with said cell cavities negative in pressure, working an impregnating agent force feeding section, and pressure injecting the impregnating agent into the cell cavities and the cell cavities communicated with. CONSTITUTION:An impregnation device consisting of an impregnating agent force feeding section 1 and an impregnating agent suction section 2 is provided, which is fixed onto one cut end face 3a cut in a manner that the impregnating agent force feeding section 1 of an impregnation device traverses in the trunk axial direction of a timber 3 or the like by using a fitment 10, while the other cut end face 3b is fixed in a manner that the impregnation suction section 2 corresponds to the impregnation force feeding section 1 by means of the fitment 10. Then, the impregnation suction section 2 is worked by a pressure reducer 9 to make cell cavities of a corresponding cut end face (a) and cell cavities 3c communicated with said cell cavities negative in pressure. Almost simultaneously, the impregnation force feeding section 1 is worked by an impregnation pressure applying device 6 to pressure inject an impregnating agent into cell cavities and the cell cavities 3c communicated with in the corresponding cut and face 3a. The inside of cell cavities are filled with the impregnating agent and made to be in the circulating state, and the impregnating agent is infiltrated even into a core section.

摘要： PURPOSE:To obtain wood for processing by heating pine blight-developed pine wood in a specific non-flammable gas atmosphere to kill and/or repel the relevant eelworms and the insect pests mediating said eelworms. CONSTITUTION:(A) Pine blight-developed pine wood is put into e.g., a closed-type heating kettle whose inner space is filled with (B) an atmosphere containing >=90% of non-flammable gas such as nitrogen or carbon dioxide, and heated for >=30min so that the temperature of the wood A reaches 50-250 deg.C at its center to kill the pathogen etc., thus obtaining the objective wood.
