As for the wooden compartment _heterowave absorbing plate 'f has the wood component with the τ, the magnetic material element, the electromagnetic miscellaneous miscellaneous wood, the electromagnetic absorption characteristics and the _ sex. The contact and strength. The co-five of the ship's money. Main quality constituents (1) Wood materials are easy to process. Therefore, if the coated magnetic wood or the internal structure is changed by changing the surface structure of the wood material, the magnetic impurities and radio wave absorption characteristics of the powder type magnetic wood τ magnetic wood are produced. For example, when coating _ sex wood, irregularities are formed on the surface of the wood. The embossing is formed by machining into a depth of about 5_parallel lines, lattices, or cylindrical grooves. The diameter of the parallel linear or lattice-shaped side column-shaped grooves is urgent, and it is preferably a contact surface. The ratio of the area of the trench to the area of the wood (four) is preferably about %. As the area of the groove increases, the frequency of the wave ♦ increases. 1261643 Qian Wei hides in the low _ field until the end of the test, the fine-grained magnetic wood is better, but in the area where the 2 or more is deleted, the depth of the line is about 5 sides of the parallel line, lattice or columnar groove. Coating or subsequent magnetic coating or magnetically-coated magnetic wood on this groove exhibits a magnetic flux loss exceeding that of coated magnetic wood (without grooves). In the case of powder type wood, the internal structure is changed by adjusting the shape of the powder or the magnetic powder and the chalk rate. Because it can form a layer of any position, it can be (4) and machine-like heterogeneity and even radio wave absorption characteristics. Further, the coated sap-like wood has a problem that the gravity or impact of the peeling or sound-insulating tile due to the change of the year has a problem of magnetic phase filamentation or is difficult to apply to the curved surface, but the problem can be alleviated. (2) The wood material has an easy addition of jade. Therefore, by applying a cut mark to the surface portion of the wood material, that is, artificially applying a strip-like cut, an impregnated magnetic wood in which the amount, direction, and uniformity of the magnetic fluid or the fine particles can be arbitrarily adjusted can be produced. • In the production technique of shell-type magnetic wood for 纟4, in addition to magnetic fluid injection and uniformity, it has various problems such as magnetic properties, but it can adjust the magnetic properties of magnetic wood and magnetic anisotropy. Sexual and radio wave absorption characteristics. By adding a cut perpendicular to the wood fiber to the surface of the board, it is possible to make a surface that is flattened with the wood fiber and to uniformize the impregnation of the magnetic fluid and to produce a magnetic wood having a magnetic property of a uniform sentence. The magnetic wood having a uniform magnetic property along the whole can be provided by cutting the partition or making the resulting laminating material in the direction of the positive or the like. Since the cross-surface of natural wood (refers to the cross section perpendicular to the wood fiber, you can observe 10 1261643 _ 〖, section (& table * perpendicular to the wood fiber section, you can also observe the surface of the wheel) The system is looking for (four) impregnated magnetic Zhao, when the stone is in the wood, the texture is cut by the texture 2, II is made by the magnetic fluid, although the amount of impregnation is approximately doubled, but the hunting is followed by the wood after the impregnation. The compression processing is performed in the thickness direction, and the specific gravity is proportional to the compression ratio of the spot. The compression ratio is preferably about 10 to 60%. The complex magnetic permeability and the electric wave absorption characteristic are greatly improved by performing two processes of cutting and compression. The electric Lubo absorption rod f is a magnetic permeability reduction of 1 〇 to 15 GHz. It is about _ ～~3.

When a hard magnetic material such as a magnet, a magnetic guide wire, a magnet powder, a film, or a fine particle is used, that is, 1216643 can control the amount of radio wave penetration.

The powder type magnetic wood is superior in magnetic properties, and the frequency of the radio wave absorption characteristic is 2 〇 dB in the wide band, and it is known that it is superior as a radio wave absorbing material. 13 1261643 Example 2 As shown in Fig. 5, a cylindrical, parallel-line, lattice-shaped concave-convex groove was applied to the surface of the wood coated with the magnetic paint. The cylindrical groove is made up of 14 rows and 14 columns of 1 () mm, hetero--grooves every 1G_ from the edge of the wood from the edge of the wood. The edge of the grooved lion wood of the flat jug is from the place of 17mm. (4) Set the groove of width 6mm and depth 4mm. The lattice-like concave-convex grooves are such that the wood in which the parallel-line-shaped grooves are applied is reduced by (10) degrees, and the application of the grooves is processed so that the entire grooves are lattice-like. It is coated with a smear-like mixed oxygen and spray varnish. The lion is slanted, and the slanted leather belt surrounds the square side and is coated with a plywood (manufactured by Nippon Kitajima Co., Ltd., trade name: shirt (4). The film was dried at room temperature for 24 hours. Figures 6 and 7 show the respective radio wave absorption characteristics. When compared with the comparative examples shown below, it was found that excellent radio wave absorption characteristics were exhibited. From the results of the experiment, almost no decoration was found. The board affects the radio wave absorption characteristics from 1 GHz to 7 GHz. Therefore, even if it is laminated on a magnetic wood board, wood or wood which can function as heat insulation, sound absorption, humidity control, warm adjustment, and wood sensation is also used. It can be regarded as not affecting the ripple and the 4 inch of the magnetic wood. The comparison results of the three kinds of buried magnetic woods, etc., can be understood from the measurement results of the radio wave absorption characteristics from 1 GHz to ioghz. The results of measuring the radio wave absorption characteristics of the embedded embedded magnetic wood are the most advantageous.

The shape of the triangular groove shape is formed. The position of the surface and the surface of the cut is formed to be separated. The aqueous magnetic fluid (W-35) was used as a miscellaneous material, and the magnetic fluid and the wood sample were inserted into a vacuum heating and dipping apparatus, and the pressure was reduced by about 5. 3 kPa for 2 hours and a half, and pressurized for about 882 kPa for 2 hours and a half. After the completion of the impregnation step, 'completely dry and complete the dip (4) magnetic wood. As for the comparison sample, the Japanese red pine plywood laminated magnetic wood, Japanese pine pine (lumber), fir logs are used. The impregnated magnetic wood. The obtained magnetic wood is laminated in parallel with the direction of the wood fiber and in the vertical direction. The results of the specific gravity measurement of the sample cut every 10 cross-sections of the wood are used to evaluate the magnetic properties. The amount of impregnation of the fluid and the state of impregnation. The first graph shows the average value of the specific gravity of the dip-type magnetic wood, and the specific gravity of the wood after the magnetic fluid is impregnated, minus the specific gravity of the wood before the magnetic fluid is impregnated. Derivation of the cross-section of the wood from the amount of immersion of the magnetic fluid, showing the wetting length of the magnetic fluid. In the impregnated magnetic wood, the ply laminate can increase the impregnation of the magnetic fluid. Uniformity. Figure 11 shows the results of the evaluation of the complex permeability of the wood cross-sections (a) and (b). The cut, vertically laminated samples show higher magnetic properties and uniformity.
