    • A method of producing a needle-like diamond structure including the steps of forming a layer of anodized alumina on a diamond substrate, the anodized alumina having a plurality of through holes; vapor-depositing a substance resistant to plasma etching by a vacuum vapor-depositing method to form dots on said diamond substrate, wherein the layer of anodized alumina acts as a mask for the vapor deposition; removing the anodized alumina; and performing a plasma etching treatment while using the dots as a mask, thereby forming regularly-arranged, needle-like diamond columns.
    • 一种制造针状金刚石结构的方法,包括以下步骤:在金刚石基底上形成阳极化氧化铝层,所述阳极化氧化铝具有多个通孔; 通过真空气相沉积方法气相沉积耐等离子体蚀刻的物质,以在所述金刚石基底上形成点,其中阳极氧化的氧化铝层用作气相沉积的掩模; 去除阳极氧化的氧化铝; 并且在使用点作为掩模的同时进行等离子体蚀刻处理,从而形成规则排列的针状菱形柱。

    • An anode (3) and a cathode (5), interposing a solid polymer film (7), are disposed. While supplying purified water from a supply port (13a) of an anode chamber (13), wherein the anode (3) is disposed, and a supply port (15a) of a cathode chamber (15), wherein the cathode (5) is disposed, direct electric current is applied between the anode (3) and the cathode (5). As a result, ozone-water is discharged from an outlet port (13b) of the anode chamber (13). In such an electrolysis cell (1), a free-standing conductive diamond plate, formed by microwave plasma assisted CVD so as to have a thickness of 0.8 mm, is used as the anode (3). The diamond plate is provided with holes, having a diameter of 1 mm and disposed such that a center distance therebetween becomes 2 mm. Therefore, the electrolysis cell (1) can stably produce ozone without causing exfoliation of the anode (3), even when high voltage and large current are applied between the anode (3) and the cathode (5).
    • 设置插入固体聚合物膜(7)的阳极(3)和阴极(5)。 在从设置有阳极(3)的阳极室(13)的供给口(13a)和阴极室(15)的供给口(15a)供给净化水的同时,其中阴极(5)为 在阳极(3)和阴极(5)之间施加直流电流。 结果,臭氧水从阳极室(13)的出口(13b)排出。 在这种电解槽(1)中,使用通过微波等离子体辅助CVD形成的厚度为0.8mm的独立导电金刚石板作为阳极(3)。 金刚石板设置有直径为1mm的孔,并且设置成使得其间的中心距离为2mm。 因此,即使在阳极(3)和阴极(5)之间施加高电压和大电流的情况下,电解槽(1)也可以稳定地产生臭氧而不会使阳极(3)发生剥离。
