    摘要: The present invention relates to a method to produce a solid electrolytic capacitor by forming a dielectric layer on an anode body comprising a valve-acting metal sintered body having fine pores and forming on the dielectric layer a conductive compound layer to form a cathode, wherein a cathode is formed by repeating the step of dipping the anode body into an inorganic compound solution, an organic compound solution or a conductive-polymer compound dispersion liquid which turns into a conductive compound layer to thereby laminate a conductive layer on the anode body, and the depth of the anode body to be dipped is increased with each dipping; and an apparatus to be used for the method. According to the present invention, a satisfactory cathode layer can be efficiently formed and a solid electrolytic capacitor having a large capacitance and a low equivalent series resistance can be produced.

    摘要: A polishing device (1) includes a processing vessel (10) into which workpieces are charged, a fluidizing unit that fluidizes the workpieces in the processing vessel, an abrasive-feeding unit (30) that feeds an abrasive into the workpieces, and a suction unit (40) that generates an air flow in a direction in which the abrasive passes through the processing vessel (10), and recovers the abrasive by suction. The abrasive fed from the abrasive-feeding unit (30) is allowed to pass between the workpieces charged into the processing vessel (10) by the air flow generated from the suction unit (40) while coming into contact with the workpieces. Accordingly, the workpieces are polished.
