Publication number: 20200408464Abstract: An air knife for discharging a stream of gas onto a sheet of material. The air knife includes a main body including an inlet portion and an outlet portion, and a plurality of inlet ports. The inlet portion defines a plenum. The outlet portion defines an exit orifice in fluid communication with the plenum. The inlet ports project from the inlet portion and each inlet port comprises a passageway in fluid communication with the plenum. In some embodiments, the inlet ports project from a rear, or trailing, wall of the main body. In other embodiments, the outlet portion terminates at an exit face in which the exit orifice is formed, with a tip region of the outlet portion forming a taper angle of not more than 90 degrees in extension to the exit face.Type: ApplicationFiled: February 26, 2019Publication date: December 31, 2020Inventors: Hironori Fukuyama, Hiroyuki Kamei, Hsi-Ta Lin, Weiwei Luo, Elias Panides, Jingru Zhang Benner

Patent number: 8966729Abstract: In sputter etching to improve the adhesion between upper electrodes and lead electrodes, the sputter etching of surfaces of the upper electrodes under an Ar gas flow at a flow rate of 60 sccm or more can reduce the residence time of Ar ions on the surfaces of the upper electrodes because of the Ar gas flow. This can prevent the charging of the upper electrodes due to the buildup of ionized Ar gas on the surfaces, reduce the influence of charging on piezoelectric elements, and provide a method for manufacturing a piezoelectric actuator that includes the piezoelectric elements each including a piezoelectric layer having small variations in hysteresis characteristics and deformation characteristics.Type: GrantFiled: March 3, 2011Date of Patent: March 3, 2015Assignee: Seiko Epson CorporationInventors: Hironobu Kazama, Takahiro Kamijo, Masato Shimada, Hiroyuki Kamei, Yuka Yonekura, Motoki Takabe
