    Abstract: PROBLEM TO BE SOLVED: To reduce drive voltage of a piezoelectric ink jet module and improve injection accuracy.SOLUTION: Polymer films (for example, flexible print members 30, 31, 32) located between piezoelectric elements 34, 34' and storage parts in an injection body provide an effective seal for the storage parts and electrodes are positioned on the side of the piezoelectric element 34, 34' in which operation is performed, thus reducing the magnitude of the drive voltage. This location of the flexible members can enhance electrical and mechanical separation between the storage parts, so as to improve injection accuracy. The deformation characteristic of the polymer further reduces distortion of an ink jet head.

    Abstract: PROBLEM TO BE SOLVED: To provide a piezoelectric film having improved physical properties close to the piezoelectric performance of a single crystal. SOLUTION: The piezoelectric film 18 includes a needlelike seed crystals 5 deposited on a substrate 10. The piezoelectric film 18 is produced through a step of placing the needlelike seed crystals 5 on the substrate 10, a step of determining the orientation of the needlelike seed crystals 5 on the substrate 10 and a step of growing the piezoelectric film 18 from the seed crystals 5. The seed crystals 5 each are a crystal material serving as a nucleus of the growth of a bulk crystal or a crystal film. The orientation-determined needlelike crystals 5 finally incorporated in the piezoelectric film 18 serve as a nucleus of the growth of a crystal area which will grow to form the piezoelectric film 18. For a thickened piezoelectric film, a growth time can be extended or a film formation process can be repeated until a desired film thickness is achieved. COPYRIGHT: (C)2011,JPO&INPIT

    Abstract: A method and system of facilitating development of fluids having a variety of elemental compositions are disclosed. A graphical user interface allows user interaction with a lab deposition system to control fluid drop ejection of fluids through multiple nozzles. Fluid drop ejection and drop formation can vary from fluid to fluid, and require adjustments to waveform parameters of a drive pulse applied to the multiple nozzles. The system implements a drop watcher camera system to capture real-time still and video images of fluid drops as they exit the multiple nozzles. The captured drop formation of the fluid drops are displayed to the user, and based on the images the waveform parameters are adjusted and customized specific for individual fluid. In addition to adjusting the drive pulse that effects fluid drop ejection, a tickle pulse can also be adjusted and customize to prevent clogging of the nozzles.

    Abstract: A fluid ejector having an inner surface, an outer surface, and an orifice that allows fluid in contact with the inner surface to be ejected. The fluid ejector has a non-wetting monolayer covering at least a portion of the outer surface of the fluid ejector and surrounding an orifice in the fluid ejector. Fabrication of the non-wetting monolayer can include removing a non-wetting monolayer from a second region of a fluid ejector while leaving the non-wetting monolayer on a first region surrounding an orifice in the fluid ejector, or protecting a second region of a fluid ejector from having a non-wetting monolayer formed thereon, wherein the second region does not include a first region surrounding the orifice in the fluid ejector.

    Abstract: In the embodiments described in the specification, electrodes (31) are bonded to the surface of a ceramic piezoelectric layer (10) by supporting electrodes having a reduced dimension on a flexible dielectric film (30) and placing the dielectric film under tension to expand the film (30) and the electrodes (31) sufficiently to conform the electrodes (31) to the desired electrode pattern on the ceramic piezoelectric layer (10). The electrodes (31) are then bonded to the piezoelectric layer (10) with an adhesive bonding agent (22) under pressure applied hydraulically so as to be distributed uniformly throughout the surface of the piezoelectric layer. In one embodiment the dielectric film (30) also carries conductor arrays (35) for connecting the electrodes (31) to remote driver chips at locations spaced from the surface of the piezoelectric layer (10).
