Abstract:
An inkjet printhead is provided comprising ink drop generators formed in a substrate at a density of greater than approximately ten ink drop generators per square millimeter of the substrate and ink channels formed in the substrate for supplying ink to ink drop generators. The ink drop generators are arranged in approximately parallel rows. The ink channels are arranged to supply ink to the rows of ink drop generators. The ink drop generators in each row are arranged in a plurality of groups, with each group in fluid communication with a respective ink supply channel.
Abstract:
An inkjet printhead IC is fabricated using a wafer substrate that defines a plurality of ink inlet channels. A plurality of nozzle structures fabricated on the substrate to define nozzle chambers are in fluid communication with the ink inlet channels and an ink ejection nozzle in fluid communication with each nozzle chamber. Each nozzle structure has a chamber, an ejection nozzle in fluid communication with the chamber, and an ejection member for acting on ink within the chamber. A plurality of actuators attached to the substrate move each of the ejection members respectively, the movement being substantially parallel to the ink inlet flow direction; such that, ink is ejected through the ejection nozzle upon activation of the actuator corresponding to that nozzle structure.

An ink jet printhead chip includes a substrate that defines a plurality of ink inlet channels. A plurality of nozzles is positioned on the substrate and is in fluid communication with the ink inlet channels. A plurality of elongate micro-electromechanical actuators is fast with the substrate at one end, an opposed end being displaceable relative to the substrate on receipt of an electrical drive signal. Each opposed end is operative on a respective nozzle to eject ink from the nozzle. Control circuitry and drive circuitry for each actuator is positioned on the substrate and interposed between the actuator and the substrate.

Abstract:
The present invention provides methods of producing a surface with enhanced cell-adhesive properties comprising applying a stress to a polymeric matrix. The strained matrix is then modified by grafting a self-assembled monolayer onto the strained matrix, with the self-assembled monolayer comprising at least one exposed functional group. At least one cell-adhesive molecule can then be coupled to the at least one exposed functional group on the self-assembled monolayer to produce a surface with enhanced cell-adhesive properties.

Abstract:
An ink jet print head chip that includes a substrate that defines a plurality of ink inlet channels. A plurality of nozzle chamber structures is on the substrate to define nozzle chambers in fluid communication with the ink inlet channels and an ink ejection nozzle in fluid communication with each nozzle chamber. Drive transistor circuitry is positioned on the substrate and is connectable to data and power supplies. A plurality of elongate actuators are each fast with the substrate at one end to receive actuating signals from the drive transistor circuitry to be displaceable towards and away from the substrate. A plurality of ink ejection members is fast with respective actuators at opposite ends. Each ink ejection member is positioned in a respective nozzle chamber such that displacement of the respective actuators results in the ejection of a drop of ink from the ink ejection nozzle. The transistor circuitry includes traces that are interposed between each actuator and the substrate and oriented substantially orthogonally to a longitudinal axis of each respective actuator.
Abstract:
A method and apparatus for preheating golf balls prior to painting. The process includes forming golf balls with covers, heating, coating, and further heating the golf balls in a heated enclosure. The apparatus includes a ventilated holding tray that in addition to supporting the golf balls with a minimum of contact between balls and tray will allow for a thorough flow of heat about the balls for quick and uniform heating. This also will aid in reducing blemishes to the golf balls, by suspending freshly painted golf balls on conical pins set at right angles to the balls, thereby reducing the physical contact between the tray and freshly painted golf balls. The tray comprises replaceable ball support inserts. The inserts will generally be made from injection molded plastic and will be friction-fitted to the tray, and if damaged can be easily and inexpensively replaced.
