Abstract: A droplet dispensing apparatus includes a crystal sensor, a resonance frequency measuring unit, and a controller. The controller is configured to obtain the resonance frequency of the crystal sensor before droplets are discharged from a liquid dropping device, control the liquid dropping device to discharge droplets on to the crystal sensor, and obtain the resonance frequency of the crystal sensor after droplets are discharged from the liquid dropping device. The controller estimates a volatilization amount for the droplets on the crystal sensor based on a temporal change trend in the resonance frequency of the crystal sensor and calculates the total weight of the droplets discharged from the liquid dropping device based on the difference in resonance frequency of the crystal sensor before and after the droplets are discharged and the estimated volatilization amount.

Abstract: An ink jet head includes a substrate having a pressure chamber formed therein, the pressure chamber being in communication with a nozzle through which ink is to be discharged, a first plate that is deformable to change a volume of the pressure chamber, and a second plate between the first plate and the pressure chamber, that stretches in response to an electric signal applied thereto. The second plate contracts in an in-plane direction to cause the first plate to deform and thereby the volume of the pressure chamber to be enlarged, when the electric signal is applied, and the second plate returns to an original shape thereof to cause the first plate to return to an original shape thereof and thereby the volume of the pressure chamber to return to an original volume thereof, when the electric signal is no longer applied.
