Patent number: 9174442Abstract: According to one embodiment, an inkjet head includes: a nozzle plate including plural nozzles; a piezoelectric element including plural pressure chambers corresponding to the nozzles and sidewalls provided adjacent to the pressure chambers and serving as driving elements configured to press the pressure chambers to eject liquid from the nozzles; a substrate to which the piezoelectric element is bonded; and a frame member placed on the substrate to surround the piezoelectric element. Grooves are formed on the upper end, and in which an adhesive is applied to bond the upper ends of the sidewalls and the nozzle plate.Type: GrantFiled: April 29, 2014Date of Patent: November 3, 2015Assignee: Toshiba Tec Kabushiki KaishaInventors: Nobuaki Murochi, Hiroyuki Kushida

Patent number: 8708464Abstract: According to one embodiment, an ink jet head includes: a nozzle plate including plural nozzles; a piezoelectric element including plural pressure chambers corresponding to the nozzles and sidewalls provided adjacent to the pressure chambers and functioning as driving elements that press the pressure chambers to eject liquid from the nozzles; a substrate to which the piezoelectric element is bonded; a frame member placed on the substrate to surround the piezoelectric element; and electrodes for driving the piezoelectric element. The piezoelectric element includes slopes continuous to the upper end of the piezoelectric element and not in contact with the nozzle plate. The substrate has a surface layer formed on the surface thereof and includes recess continuous to the slopes in the surface layer. The electrodes are formed on the slopes and the recess.Type: GrantFiled: March 1, 2012Date of Patent: April 29, 2014Assignee: Toshiba Tec Kabushiki KaishaInventors: Hiroyuki Kushida, Nobuaki Murochi
