摘要： The present invention is intended to provide a method of manufacturing an ink jet head having good stable-ejection characteristics, and an ink jet head. The invention is an exemplary method of manufacturing an ink jet head having a cavity that contains liquid and a nozzle that communicates with the cavity, and ejecting the liquid contained in the cavity from an ejection orifice of the nozzle with using a nozzle opening at an opposite side of the cavity as the ejection orifice. The exemplary method includes making an ejection orifice on a side of the nozzle have a taper portion in which the diameter increases progressively toward the ejection orifice side and forming lyophobic films and lyophilic films alternately on the taper portion inside the nozzle so as to form a stack film, and forming a lyophobic film inside nozzle in which annular end surfaces of the lyophobic films and annular end surfaces of the lyophilic films are exposed alternately by grinding the stack film on the taper portion to expose a side section of the stack film.

摘要： A drive waveform-determining device is configured and arranged to determine an exact drive waveform for a droplet discharge device with minimal trials. The drive waveform-determining device uses an analysis unit that stores optimal weight and velocity for droplets, and basic configurations of drive waveforms. A weight- and viscosity-determining unit measures the weight of droplets discharged from a discharge head. The analysis unit measures the velocity of the droplets with the aid of a CCD camera and a strobe light. The analysis unit reads a basic configuration of a drive waveform and adjusts the drive waveform so that the measured weight and velocity match the weight and velocity stored in the analysis unit. The analysis unit then stores the adjusted drive waveform.
