PURPOSE:To improve the emitting characteristics of liquid droplets even if the length of a liquid flowline is made short so as to accelerate the replenishing speed of a liquid, by performing the input of the same signal to a signal, which is inputted in order to generate energy in a downstream energy generating part, within a specific time in an upstream energy generating part. CONSTITUTION:The input timing T of the signal inputted to an upstream energy generator 102 is set on the basis of the point of time when a signal is inputted to a downstream energy generator 101 and, when the interval of the energy generator 101 and the energy generator 102 is set to L and the propagation speed of energy propagating through a liquid is set to A, it is desirable to form formula -L/A<T<L/A and, more pref., T is brought to zero. In addition, a signal inputting time is pref. adjusted so that energy generated by one energy generator does not continue after energies respectively generated by two energy generators are collided. By this method, even if the length of a liquid flowline is made short and the replenishing speed of a liquid is enhanced, the emitting characteristics of liquid droplets can be improved. |
