    摘要: A fluid ejection module includes a flow-path body, a first oxide layer, a membrane, and a second oxide layer. The flow-path body has a first outer surface and an opposing second outer surface and a plurality of flow paths, each flow path extending at least from the first outer surface to the second outer surface. The first oxide layer coats at least an interior surface of each of the flow paths and the first and second outer surfaces of the flow-path body and has a thickness that varies by less than 5% along {100} planes. The membrane has a first outer surface. The second oxide layer is coated on the first outer surface of the membrane and has a thickness that varies by less than 5% along {100} planes and is bonded to the first oxide layer.

    摘要: Techniques are provided for forming nozzles in a microelectromechanical device. The nozzles are formed in a layer prior to the layer being bonded onto another portion of the device. Forming the nozzles in the layer prior to bonding enables forming nozzles that have a desired depth and a desired geometry. Selecting a particular geometry for the nozzles can reduce the resistance to ink flow as well as improve the uniformity of the nozzles across the microelectromechanical device.

    摘要: Optical fibers are inserted and bonded in a two dimensional array of feedthroughs provided by an insert having a top plate, a bottom plate and a sandwiched spacer plate. Top and bottom plate feature funnel shaped hole sections that capture the approaching fiber end during its insertion. The funnel sections terminate in narrow hole sections that tightly hold the inserted fiber ends. Having top and bottom plate spaced apart provides for high angular precision of the bonded fiber ends with minimal fabrication effort of the insert. Optical fibers may be combined in linear arrays and simultaneously inserted significantly reducing assembly efforts. The insert is attached to a fiber housing and hermetically sealed within an external housing, which features a glass plate to provide beam propagation to and from the fiber ends. An optical gel fills the gap between the insert's output face and the glass plate.

    摘要: A method of forming an actuator and an actuable device formed by this method are disclosed. This method includes depositing a photoimageable material to form a first photoimageable layer on a piezoelectric layer; patterning the first photoimageable layer to form an aperture; and disposing a first conductive layer on the first photoimageable layer. The first conductive layer partially overlies the first photoimageable layer such that a first portion of the first conductive layer contacts the first photoimageable layer and a second portion of the first conductive layer electrically contacts the piezoelectric layer in the aperture.
