Patent number: 10012665Abstract: 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.Type: GrantFiled: February 9, 2011Date of Patent: July 3, 2018Assignee: MICROJET CORPORATIONInventor: Shuichi Yamaguchi
