In order to expand the application field of the multilayer piezoelectric actuator, it has aimed to establish the technology that uses the impulsive force generated when the voltage is rapidly impressed to the element. First, a stepwise motion mechanism was made. Successive impulsive force is acted on a mass supported with a spring. The mechanism moves using difference between inertia force and friction force. Its driving characteristics were examined. Next, a jet pump that ejects a small amount of fluid by using a rapid expansion of the element was made. As an application of the jet pump, a sorter of the particle that flowed in the conduit was designed and its sorting characteristics were examined

为了扩大多层压电致动器的应用领域，旨在建立利用电压快速压入元件时产生的冲激力的技术。首先，制作了一种阶梯运动机构。连续的冲力作用在用弹簧支承的物体上。该机构利用惯性力和摩擦力的差来运动。对其驱动特性进行了测试。接着，制造了一个喷射泵，利用元件的快速膨胀喷射出少量的流体。作为射流泵的一种应用，设计了一种在管道中流动的颗粒分选器，并对其分选特性进行了测试
