    • Using a metal mold (20a) consisting of a convex mold part (21a) and a concave mold part (22a), a molding material (14) is placed between a pair of coating films (12), and after claming, the molding material (14) and the coating film (12) are heated and molded to make a biodegradable expanded molded article, and at the same time, the coating film (12) is softened and pressure-bonded to a surface of the biodegradable expanded molded article. An exhaust hole (31a) and (32a) are provided on the convex mold part (21a) and the concave mold part (22a), respectively. At the time of heating and molding, gaseous matter existing between the coating film (12) and a surface of the metal mold (20a) is discharged out of the metal mold (20a) through the exhaust holes (31a) and (32a). Accordingly, it is possible to provide a method and a mold to manufacture a biodegradable expanded molded article easily and with excellent accuracy of dimension, having enough strength, enough water resistance, very excellent biodegradability and excellent surface smoothness even if the biodegradable molded article has a complicated shape.
    • 使用由凸模部分(21a)和凹模部分(22a)组成的金属模具(20a),将成型材料(14)放置在一对涂膜(12)之间, 将成型材料(14)和涂膜(12)加热成型,制成生物降解性发泡成型体,同时使涂膜(12)软化并压接在生物降解性膨胀型 模制品。 排气孔(31a)和(32a)分别设置在凸模部分(21a)和凹模部分(22A)上。 在加热成型时,存在于涂膜(12)和金属模具(20a)的表面之间的气体物质通过排气孔(31a)和(a1)从金属模具(20A)排出出 32 a)。 因此,即使可生物降解的成型体具有可以生物降解的成型体,也可以容易且具有优异的尺寸精度,具有足够的强度,足够的耐水性,极好的生物降解性和优异的表面平滑性来制造可生物降解的发泡成型体的方法和模具 复杂的形状。

    • A liquid droplet ejecting head includes: one or more nozzle holes ejecting liquid droplets; one or more pressure liquid chambers communicating with the nozzle holes and containing liquid to be ejected; a common liquid chamber communicating with the pressure liquid chambers; one or more diaphragms each forming a wall face of the corresponding pressure liquid chamber; one or more vibration chambers containing air gaps provided in contact with the diaphragms on the opposite side from the pressure liquid chambers; and one or more electrodes provided to oppose the diaphragms through the air gaps. The liquid droplet ejecting head further includes: a deformable plate whose deformation is greater than the total deformation of the diaphragms, the deformable plate forming a wall face of the common liquid chamber, and a pressure correcting chamber provided across the deformable plate from the common liquid chamber so as to communicate with the vibration chambers.
    • 液滴喷射头包括:喷射液滴的一个或多个喷嘴孔; 一个或多个压力液体室与喷嘴孔连通并容纳待喷射的液体; 与压力液室连通的公共液体室; 一个或多个隔膜各自形成相应的压力液体室的壁面; 一个或多个振动室,其包含与压力液体室相反侧上的膜片接触的气隙; 以及设置成通过气隙与隔膜相对的一个或多个电极。 液滴喷射头还包括:可变形板,其变形大于膜片的总变形,形成公共液体室的壁面的可变形板,以及设置在可变形板上的公共液体的压力校正室 以便与振动室连通。
