摘要： PURPOSE:To uniformly and rapidly pour a liquid not only into the sap wood part but also into the heat wood part of wood so as to be able to rapidly remove moisture not only from the surface layer part but also from the interior of the wood by a method wherein the liquid is poured through holes, which are produced by irradiating laser beams over the wood, in the wood. CONSTITUTION:After holes are produced by irradiating laser beams to wood, liquid is poured through the holes made by lasing in the wood. Any laser including gas laser such as CO2 laser or the like can be used for the laser beams. Only by irradiating laser beams on the surface of the wood, deep holes are easily obtained. By producing the holes with the laser beams, the part of wood material is decomposed, evaporated and vanished by being heated up to high temperature without destruction and crush of the cell wall of the wood, resulting in exposing the cell wall surface in the holes made by lasing. Accordingly, gas and liquid more easily move in the wood than they move when holes are produced by mechanical incising treatment.

摘要： PURPOSE: To reduce the heating time and remove the internal stress in order to increase the percentage of good product by heating wood from the inside at the specified water content using a dielectric heating method. CONSTITUTION: The adequate water contents to remove the internal stress of woods using the dielectric heating is at least over the air drying water content and desirably a little under the fiber saturation point. An example of the dielectric heating is achieved covering the wood surface with a heat-resistance sheet. It is recommended to heat the wood over 40 deg.C for the specified time using the dielectric heating in order to prevent oozing of resin from the wood. The water content is indicated with the percent value of the water weight in the wood divided by the dry weight of the wood. The air drying water content is defined as the water content of wood reached a stable value placed under the normal field condition for a long time; it depends on the place and the season. The fiber saturation point is defined as the water content at the condition that the wood contains saturated bound water in the fiber cells.

摘要： PURPOSE:To obtain a method for improving the quality of wood hard to generate a crack, short in a treatment time and capable of suppressing the exudation of resin without losing gloss by subjecting wood to dielectric heating at temp. decomposing a part of the resin component of wood and condensing or polymerizing the other part thereof and subsequently subjecting the same to dielectric heating at temp. lower than that temp. CONSTITUTION:In dielectric heating, the heating temp. due to the dielectric heating of the first stage may be set to temp. necessary for oxidizing and decomposing a part of the resin components in wood to chemically change the same to a low- molecular component easy to volatilize and condensing or polymerizing the other part thereof to chemically change the same to a high-molecular component hard to move. The heating temp. is different for different type of resin but generally 60-120 deg.C. The heating temp. due to the dielectric heating of the second stage may be set to temp. capable of discharging the low-molecular component easy to volatilize among resin components to the outside of wood by an evaporation phenomena. This heating temp. is different for different type of resin but generally about 60 deg.C or lower. By this method, the exudation of resin is suppressed and the surface gloss of wood is not lost and a treatment time is made short to lower manufacturing cost.

摘要： A method for preservation treatment of wood comprises the steps of radiating a laser beam on a part of the surface of the wood at the least to form small holes therein, impregnating the wood with a preservative, and then applying high frequency waves to the wood to dry it by dielectric heating.
