摘要: A droplet forming device is provided. The droplet forming device includes a liquid holder configured to hold a liquid, a film having a discharge hole, two or more vibration generators configured to vibrate the film, and a driver configured to apply a driving signal to the vibration generators. One or more of the vibration generators are disposed in each region on the film where a polarity of bending moment differs.

摘要: A liquid droplet forming device includes a liquid droplet discharger that discharges, as a liquid droplet, a particle suspension liquid in which one or more fluorescent particles are suspended; a light source for irradiating light onto the flying liquid droplet discharged from the liquid droplet discharger; a photodetector that receives fluorescence that is emitted by the one or more fluorescent particles included in the liquid droplet in response to the light as excitation light; and a particle number detector that detects a number of the one or more fluorescent particles included in the liquid droplet based on information from the photodetector.

摘要: Provided is a liquid droplet forming device including: a liquid container capable of containing a liquid; a membranous member disposed at a bottom of the liquid container and including a discharging hole; a deforming unit capable of deforming the membranous member; and a driving unit configured to drive the deforming unit by outputting a discharging signal for deforming the membranous member to discharge the liquid or a suppressing signal for suppressing residual vibration of the membranous member, wherein the suppressing signal is a signal based on natural vibration period T0 of the membranous member, wherein an amplitude of the suppressing signal is lower than or equal to an amplitude of the discharging signal, and wherein interval time Ti from when outputting of the discharging signal is ended until when outputting of the suppressing signal is started satisfies a formula: Ti=(m−½)×T0, where m represents a positive integer.
