  • Structure of stacked inkjet head
    Patent number: 7108360
    Abstract: A structure of the stacked inkjet head is composed of a stacked fluid structure and an actuator. At least one of the several plates in the stacked fluid structure has a junction with a tuning hole for enhancing the connection strength of the junction, accommodating overflown adhesive, and reducing structural deformation resulted from the temperature. The invention also avoids the troubles of inhomogeneous etching speeds when making nozzles or channels.
    Type: Grant
    Filed: March 17, 2004
    Date of Patent: September 19, 2006
    Assignee: Industrial Technology Research Institute
    Inventors: Chun-Fu Lu, Fa-Yuan Hsu, Howard Liu, Cheng-Yi Wang, Huen-Ling Chen, Chi-Bin Lo
