20150090807 | DISCHARGE SYSTEM AND METHOD OF DISCHARGE BY A DISCHARGE SYSTEM - A discharge system includes: a head unit including discharge heads that discharge a liquid material from nozzle openings that are communication with cavities onto a target by changing the internal pressure of the cavities using piezo elements; a viscosity estimating unit that estimates the viscosity of the liquid material by sucking the liquid material from first vessels that hold the liquid material into the cavities; and a waveform control unit that controls the voltage applied to the piezo elements according to the estimated viscosity of the liquid material. | 04-02-2015 |
20130037623 | DISCHARGE DEVICE FOR LIQUID MATERIAL INCLUDING PARTICLE-LIKE BODIES - A discharge device includes a discharge head that discharges a liquid material from a nozzle opening connected to the cavity by varying the internal pressure of a cavity using an actuator. The discharge head includes a monitoring portion provided between the cavity and the nozzle opening and the discharge device further includes a detection apparatus that detects the number and/or form of the particle-like bodies included in the liquid material in the monitoring portion of the discharge head and a control unit that drives the actuator according to the detection result of the detection unit to change the state of the particle-like bodies included in the liquid material of the monitoring portion. | 02-14-2013 |
20110298864 | DISCHARGE HEAD AND DISCHARGE APPARATUS - There is provided a discharge head including: a tubular member that includes a flat portion with an oblate shape where a cross-section of a tube path extends in a first direction, the tubular member being formed so that the flat portion includes a first wall that is flat and has an actuator attached to an outside thereof and the flat portion becomes a cavity with an internal volume thereof varying due to displacement of the first wall; and a nozzle opening that is provided at one end of the tubular member and discharges a liquid substance due to variation in the internal volume of the cavity. | 12-08-2011 |
