    • An oscillator is oscillatable in a predetermined direction. First and second driving electrodes are secured to the base and apply an electrostatic force to the oscillator to make drive oscillation of the oscillator in the predetermined direction. At the time of the drive oscillation of the oscillator, a predetermined electric charge is accumulated in the oscillator, and electric charges of opposite polarities are alternately and periodically accumulated in the first and second driving electrodes, respectively, to exert an attractive force between the oscillator and a corresponding one of the first and second driving electrodes and also to exert a repulsive force between the oscillator and the other one of the first and second driving electrodes, and vice versa.
    • 振荡器可在预定方向上振荡。 第一驱动电极和第二驱动电极固定到基座并向振荡器施加静电力,以使振荡器在预定方向上的驱动振荡。 在振荡器的驱动振荡时,在振荡器中累积预定的电荷,相反极性的电荷分别交替地周期地累积在第一和第二驱动电极中,以在振荡器之间施加吸引力 以及第一和第二驱动电极中的相应一个,并且还在振荡器和第一和第二驱动电极中的另一个之间施加排斥力,反之亦然。

    • A process for preparing a carboxylic acid ester which includes subjecting a carboxylic acid and an alcohol or a phenol to an esterification reaction in the presence of a silica-titania catalyst. The silica-titania catalyst is prepared by adding an acidic solution containing a silicon compound and a titanium compound dissolved therein to a solution of a basic compound to bring about co-precipitation, in which the acidic solution is a nitric acid-acidic solution or a sulfuric acid-acidic solution, a ratio of the amount (gram equivalent) of nitric acid or sulfuric acid to the amount (mol) of the silicon compound in the acidic solution is 0.5 to 50 and the amount of the titanium compound in the acidic solution is such that a ratio of titania (TiO.sub.2) in the silica-titania catalyst is 1 to 50% by weight.
    • 一种制备羧酸酯的方法,包括在二氧化硅 - 二氧化钛催化剂的存在下使羧酸和醇或酚进行酯化反应。 二氧化硅 - 二氧化钛催化剂通过将含有硅化合物和溶解在其中的钛化合物的酸性溶液加入到碱性化合物的溶液中来进行共沉淀,其中酸性溶液是硝酸 - 酸性溶液或 硫酸 - 酸性溶液,酸性溶液中的硝酸或硫酸的量(克当量)与硅化合物的量(摩尔)的比例为0.5〜50,酸性溶液中钛化合物的量 使得二氧化硅 - 二氧化钛催化剂中的二氧化钛(TiO 2)的比例为1〜50重量%。
