    • First, wood or bamboo is crushed to obtain wood powder with an average grain size of 5 μm to 100 μm. Next, the wood powder is put in a first mold, and a first compression molding step is carried out under the conditions that, for example, a temperature is 160° C. and a pressure is 30 MPa. Thus, a temporary molded body is obtained. Subsequently, the temporary molded body is immersed in a flame retardant and a surface of the temporary molded body is impregnated with the flame retardant. Thereafter, the temporary molded body is put in a second mold, and a second compression molding step is carried out under the conditions that, for example, a temperature is 200° C. and a pressure is 100 MPa. At this time, ingredients such as lignin and a hemicellulose are separated from the wood powder, and function as an adhesive. For this reason, pieces of crushed material are firmly bonded with each other so as to be integrated into a single body. Thus, a compression-molded product with a predetermined shape is obtained.
    • 首先,将木材或竹子粉碎,得到平均粒径为5μm〜100μm的木粉。 接着,将木粉放入第一模具中,在例如温度为160℃,压力为30MPa的条件下进行第一压缩成型工序。 因此,获得临时成型体。 随后,将临时成型体浸渍在阻燃剂中,并且将临时成型体的表面浸渍有阻燃剂。 然后,将暂时成型体放入第二模具中,在例如温度为200℃,压力为100MPa的条件下进行第二压缩成型工序。 此时,木质素和半纤维素等成分与木粉分离,作为粘合剂起作用。 因此,碎片彼此牢固地结合在一体, 因此,获得具有预定形状的压缩成型产品。

    • In a radio wave lens antenna, a lens cover for covering the surface of the lens is stably fixed to the reflector. The antenna has a semispherical Luneberg lens, a semispherical shell-shaped lens cover for covering the surface of the lens, a radio wave reflector, a ring-shaped plate placed along the outer circumference of the lens, a primary feed placed at the focal point of the lens, and a holding part for the primary feed. A flange provided at the opening edge of the lens cover is clamped by the reflector and the plate to fix the lens cover to the reflector, and more preferably, the lens cover is caused to be in contact with the lens, and the lens is pressed also in the radial direction by the plate via the lens cover.
    • 在无线电波透镜天线中,用于覆盖透镜表面的透镜盖稳定地固定到反射器。 天线具有半球形Luneberg透镜,用于覆盖透镜表面的半球形壳形透镜盖,无线电波反射器,沿着透镜的外圆周放置的环形板,放置在焦点处的主馈电 的透镜,以及用于主要进给的保持部件。 设置在透镜盖的开口边缘处的凸缘被反射器和板夹住以将透镜盖固定到反射器,更优选地,透镜盖与透镜接触,并且透镜被按压 也通过透镜盖在板的径向方向上。
