Patent number: 8573743Abstract: A liquid dispenser includes a liquid supply channel, a liquid return channel, and a liquid dispensing channel. The liquid dispensing channel includes a wall. The wall includes a surface. A portion of the wall defines an outlet opening. A drain is located in the wall downstream from the outlet opening. The drain includes a radius of curvature as viewed from a direction perpendicular to the wall. A liquid supply provides liquid that flows from the liquid supply channel through the liquid dispensing channel to the liquid return channel. A diverter member selectively diverts a portion of the flowing liquid through the outlet opening of the liquid dispensing channel.Type: GrantFiled: October 26, 2010Date of Patent: November 5, 2013Assignee: Eastman Kodak CompanyInventors: Yonglin Xie, Carolyn R. Ellinger, Maria J. Lehmann, Joseph Jech, Jr., Qing Yang

Patent number: 8439481Abstract: A liquid dispenser includes a liquid supply channel, a liquid return channel; and a liquid dispensing channel. The liquid dispensing channel includes a wall. The wall includes a surface. A portion of the wall defines an outlet opening. The outlet opening includes a downstream edge relative to a direction of liquid flow through the liquid dispensing channel. The downstream edge is sloped relative to the surface of the wall of the liquid dispensing channel. A liquid supply provides liquid that flows from the liquid supply channel through the liquid dispensing channel to the liquid return channel. A diverter member selectively diverts a portion of the flowing liquid through the outlet opening of the liquid dispensing channel.Type: GrantFiled: October 26, 2010Date of Patent: May 14, 2013Assignee: Eastman Kodak CompanyInventors: Yonglin Xie, Joseph Jech, Jr., Carolyn R. Ellinger, Maria J. Lehmann, Ali G. Lopez, Qing Yang

Patent number: 8409900Abstract: A method of fabricating a MEMS composite transducer includes providing a substrate having a first surface and a second surface opposite the first surface. A transducing material is deposited over the first surface of the substrate. The transducing material is patterned by retaining transducing material in a first region and removing transducing material in a second region. A polymer layer is deposited over the first region and the second region. The polymer layer is patterned by retaining polymer in a third region and removing polymer in a fourth region. A first portion of the third region is coincident with a portion of the first region and a second portion of the third region is coincident with a portion of the second region. A cavity is etched from the second surface to the first surface of the substrate.Type: GrantFiled: April 19, 2011Date of Patent: April 2, 2013Assignee: Eastman Kodak CompanyInventors: James D. Huffman, Maria J. Lehmann

Patent number: 8328335Abstract: A liquid dispenser is provided that includes a liquid supply channel, a liquid dispensing channel, and a liquid return channel. The liquid dispensing channel includes a wall. The wall includes a surface. A portion of the wall defines an outlet opening that includes a downstream edge relative to a direction of liquid flow through the liquid dispensing channel. The downstream edge is sloped relative to the surface of the wall of the liquid dispensing channel. A liquid is provided that flows from the liquid supply channel through the liquid dispensing channel to the liquid return channel. A liquid drop is caused to be ejected from the outlet opening of the liquid dispensing channel by selectively actuating a diverter member to divert a portion of the flowing liquid through the outlet opening of the liquid dispensing channel.Type: GrantFiled: October 26, 2010Date of Patent: December 11, 2012Assignee: Eastman Kodak CompanyInventors: Yonglin Xie, Joseph Jech, Jr., Carolyn R.
