A language conversion system converts an original sentence in a source-language into a translated sentence in a target-language. The language conversion system includes a original analysis unit for analyzing the original sentence so as to obtain an intermediate structure of the original, an idea center extraction unit for extracting an idea center from the intermediate structure obtained by the original analysis unit, the idea center being a central expression of an idea to be described by a sentence, an identification unit for identifying a sentence pattern including the idea center extracted by the idea center extraction unit, an information extraction unit for extracting information required by the sentence pattern identified by the identification unit from the intermediate structure of the original sentence, a decision unit for deciding an intermediate structure of a translated sentence based on the sentence pattern and request information extracted by the information extraction unit, and a creation unit for creating a translated sentence in a surface level from the intermediate structure decided by the decision unit.

In one embodiment of the present invention an ink manifold is divided into a first ink chamber communicated with an ink drop issuing nozzle and a second ink chamber communicated with an ink source and the first ink chamber through a narrow passage. First and second piezoelectric elements are mounted in opposed relationship with the first and second ink chambers, respectively. The second piezoelectric element is normally applied with such a second driving voltage that the ink will not issue through the nozzle. The frequency of a first driving voltage applied to the first piezoelectric element is twice as high as that of the second driving voltage, and the first driving voltage is selectively applied in synchronism with the second driving voltage only during the positive going half cycle thereof so that an ink drop may be issued through the nozzle during the positive going half cycle of the first driving voltage. In another embodiment of the present invention a plurality of ink drop generating cells substantially similar in construction to the ink drop generator described above are assembled to provide an ink drop generator having an array of nozzle matrix.
