    • Disclosed is an ink droplet expelling apparatus for expelling an ink droplet in response to an electric signal, compising a printing head provided with one or more ink chambers, electro-mechanical transducers disposed on the printing head corresponding to the ink chambers, and a driving signal generating circuit for producing electric signals for driving the electro-mechanical transducers. The elector-mechanical transducers are distorted by three different driving signals to reduce the volumes of the ink chambers to raise the pressure therein to thereby expel an ink droplet out of a nozzle formed at the front end of the head. The three driving signals are applied to the electro-mechanical transducers in a predetermined order, the first one giving the ink a velocity, the second one accelerating the ink to expel it in the form of an ink droplet out of the nozzle, the third one acting to suppress the pressure fluctuation in the ink chambers caused by the first and second driving signals as well as to supplement ink in the ink chambers from an ink tank.
    • 公开了一种用于响应于电信号排出墨滴的墨滴排出装置,组合设置有一个或多个墨室的打印头,设置在与墨室对应的打印头上的机电换能器,以及驱动信号 用于产生用于驱动机电换能器的电信号的发生电路。 机电换能器被三种不同的驱动信号扭曲,以减小油墨室的体积,以便在其中提高压力,从而将墨滴从形成在头部前端的喷嘴排出。 三个驱动信号以预定的顺序施加到机电换能器,第一个驱动信号以给定墨的速度施加到机电换能器,第二个驱动信号加速油墨以墨滴的形式将其排出喷嘴,第三个驱动信号 用于抑制由第一和第二驱动信号引起的墨室中的压力波动,以及从墨罐补充墨室中的墨。

    • A management system for use in a centrifuge equipped with a detachable rotor which is rotatable so as to separate density-different samples by a centrifugal force due to the rotation. The management system is for managing the lifetime of the rotor on the basis of the detection results of an operated-condition detector for detecting operated conditions such as the number of times of rotation, running time and rotational speed of the rotor. The management system includes a data storing device which is provided on the rotor to be rotatable therewith and is composed of a magnetic recording medium to allow keeping data relating to the operated conditions of the rotor. Also included in the management system is a data processing unit coupled through a data reading and writing device such as a magnetic head to the data keeping device and also coupled to the operated-condition detector to be responsive to the operated conditions. The data processing unit reads out previous data from the data keeping device at the time of start of operation of the centrifuge, processes the operated conditions from the detector together with the read previous data to write on the data storing device new data produced by the data processing.
