    • PURPOSE: A workpiece grinding device, using magnetorheological fluid, and a grinding method thereof are provided to flatly grind a surface of a three-dimensional structure without a curved part. CONSTITUTION: A workpiece grinding device comprises an electromagnet(110), magnetorheological fluid, a slip ring(150), and a power supply device(160). A processing window(W) for processing workpiece is formed between N-pole and S-pole of an electromagnet. The electromagnet is magnetized with the current applied in a coil(120) in order to form parallel lines of magnetic force between north and south poles. The magnetorheological fluid is located between N pole and S pole of the electromagnet. The magnetorheological fluid is rotated with the magnetized electromagnet and grinds the surface of workpiece. The slip ring supplies current to a coil of the electromagnet.
    • 目的:提供使用磁流变流体的工件研磨装置及其研磨方法,以平坦地研磨没有弯曲部分的三维结构的表面。 构成:工件研磨装置包括电磁体(110),磁流变流体,滑环(150)和电源装置(160)。 在电磁体的N极和S极之间形成用于加工工件的加工窗口(W)。 电磁体被施加在线圈(120)中的电流磁化,以在北极和南极之间形成平行的磁力线。 磁流变流体位于电磁铁的N极和S极之间。 磁流变流体与磁化电磁铁一起旋转,研磨工件表面。 滑环向电磁铁的线圈提供电流。

    • PURPOSE: An electrochemical device is provided to economically form patterns of nanotubes using anodic oxidation alumina as a substrate, to easily control a composition and phase through simple processes, to increase a reactive area, and to reduce internal loss which is generated due to resistance. CONSTITUTION: A method for manufacturing an electrochemical device comprises the following steps: forming an alumina layer(110b) through anodic oxidation of both sides of aluminum thin fragments; forming nanotubes(140) by depositing ion-conductive materials on pores of the alumina layer; eliminating the aluminum thin fragments from the alumina layer in which the nanotubes are formed; and exposing the tip of the nanotubes toe the outer part of the alumina layer by partially removing the alumina layer.
    • 目的:提供电化学装置以经济地形成使用阳极氧化氧化铝作为基底的纳米管的图案,以通过简单的工艺容易地控制组成和相,增加反应面积,并减少由于电阻而产生的内部损耗。 构成:电化学装置的制造方法包括以下步骤:通过铝薄片两侧的阳极氧化形成氧化铝层(110b); 通过在氧化铝层的孔上沉积离子传导材料形成纳米管(140); 从形成有纳米管的氧化铝层中除去铝薄片; 并且通过部分去除氧化铝层将纳米管的尖端暴露于氧化铝层的外部部分。
