    Abstract: Methods and systems for preparing a hole having an accurately controlled area in an orifice plate for a mass flow controller are provided. Methods involve forming an initial hole in the orifice plate. The initial hole has an opening having an initial area. The orifice plate comprises a material that can react to form a coating on the orifice plate. The coating occupies a greater volume than the material consumed to form the coating. The material of the orifice plate is reacted with a reactant to produce the coating and thereby produce a reduced area hole having an opening with a reduced area that is smaller than the initial area. The reduced area hole is measured. A determined amount of the coating is removed from at least the reduced area hole to produce a final hole in the orifice plate, wherein the reduced area is smaller than an opening area of the final hole.

  • Patent number: 10478347
    Abstract: A nozzle assembly may be used to apply fluid to an advancing substrate. The nozzle assembly includes a nozzle body made from a first material. The nozzle body may include one or more abrasion resistant materials fused to the nozzle body. The nozzle body may be configured to deposit a fluid, using a shim plate, onto the advancing substrate. As the substrate advances past the nozzle assembly, the substrate and/or the fluid may contact the nozzle assembly resulting in wear. The one or more abrasion resistant materials, which is different than the first material of the nozzle body, may be fused to a portion of the nozzle body to reduce the wear and prolong the life of the nozzle body. Thus, the portion of the nozzle body having the abrasion resistant material is restored rather than having to replace the entire nozzle body.

  • Patent number: 9021700
    Abstract: A method of manufacturing a liquid jet head comprises forming a terminal region on a top surface of an actuator substrate in the vicinity of a rear end thereof, and forming on the top surface a plurality of alternately arrayed ejection grooves and dummy grooves arranged in parallel to each other from a front end toward the terminal region. Shallow grooves are formed in the terminal region, and a conductive film is formed on the top surface, side surface and bottom surface of each of the ejection grooves, and on the side surface and bottom surface of the shallow grooves. The conductive film is removed from the top surface by grinding, and a cover plate is bonded to the actuator substrate so as to expose the terminal region and cover the ejection grooves. A nozzle plate is adhered to a side surface of the actuator substrate at which the ejection grooves are opened.

    Abstract: An ink jet printhead includes a nozzle plate including a nozzle, a recess in the nozzle plate, and a compliant layer that covers the recess and forms a sealed pocket that may be filled with air or another gas during use of the printhead. During actuation of a piezoelectric element during the ejection of ink from the nozzle, the sealed pocket attenuates an acoustic energy generated by the piezoelectric element, thereby reducing crosstalk to adjacent nozzles by the acoustic energy.

  • Patent number: 8991050
    Abstract: The present invention describes a method for manufacturing rotogravure cylinders with a cylinder base made of a light weight material like aluminum. The method involves the surface treatment of the cylinder with mechanical means, the copper plating in an appropriate solution, the engraving of the cylinder, and the hardening of the cylinder by chromium plating. The advantage of this method is that the chemical treatment for the preparation of the cylinder surface which generates hazardous waste is replaced by a mechanical process. In addition, the reduction of the cylinder weight considerably (e.g. for aluminum base cylinder the weight reduction is two thirds of the weight of a steel base cylinder) reduces significantly the transportation costs. Moreover, the adhesion of the copper layer to be engraved is improved and the cost and time of manufacturing reduced.
