  • Publication number: 20110089609
    Abstract: A laser-ablatable element for direct laser engraving has a laser-ablatable, relief-forming layer that has a relief-image forming surface and a bottom surface. This relief-forming layer includes a laser-ablatable polymeric binder and an infrared radiation absorbing compound that is present at a concentration profile such that its concentration is greater near the bottom surface than the image-forming surface. This arrangement of the infrared radiation absorbing compound provides improved ablation efficiency, particularly when laser exposure is carried out adiabatically.

  • Publication number: 20110073788
    Abstract: A micro-electromechanical device for controlling compressed fluid flow is provided. A chamber includes a fluid flow inlet port, a high pressure region exceeding 30 bar, and a fluid flow outlet port. A moveable micro-electromechanical valve is positioned to contact the fluid flow outlet port when the moveable micro-electromechanical valve is in a first position. An electrical connection to the moveable micro-electromechanical valve provides an electrical pulse train to the moveable micro-electromechanical valve to actuate the valve at a rate of 10 KHz or more to move the valve in order to control fluid communication between the high pressure region and a low pressure region downstream from the fluid flow outlet port.

  • Publication number: 20110073188
    Abstract: A compressed fluid microvalve for controlling flow of compressed fluid from a region of high pressure to a region of low pressure is provided. A chamber includes an inlet port, a region of high pressure, and an outlet port leading to a region of low pressure. A cantilever beam includes a first portion, a second portion, and a third portion. The cantilever beam is anchored to a portion of the chamber and is suspended in the chamber such that the first portion and third portion of the cantilever beam are exposed to the region of high pressure on all sides. The second portion of the cantilever beam overlaps the outlet port. The cantilever beam includes a first position in contact with the outlet port to prevent fluid flow from the chamber through the outlet port and a second position removed from contact with the outlet port to permit fluid flow from the chamber through the outlet port.

  • Patent number: 6634743
    Abstract: A method for increasing the diameter of an ink jet ink dot resulting from the application of an ink jet ink drop applied to the surface of an inkjet recording medium having a support having thereon an image-receiving layer and an overcoat layer, the ink penetration rate of the overcoat layer being faster than the ink penetration rate of the image-receiving layer; having the steps of: a) applying the overcoat layer on top of the image-receiving layer at a thickness less than the maximum thickness, the maximum thickness being that thickness whereby an ink jet ink drop applied to the surface of the overcoat layer will not substantially penetrate the surface of the image-receiving layer; and b) applying the ink jet ink drop on the surface of the overcoat layer whereby the diameter of the ink jet ink dot is increased relative to that which would have been obtained if the overcoat layer had been coated at a thickness of at least the maximum thickness.

  • Patent number: 5795512
    Abstract: A method for reducing curl in a stored photographic film which aids in preventing serious difficulties with downstream film transport and handling of the film. The film, which has been stored as a roll wound on a first core or mandrel is unwound from the first core and wound onto a second core or mandrel in a first direction. The film is then unwound from the second core to yield a traveling web portion. The traveling web portion is preheated to a predetermined temperature while being continuously delivered to a housing. The film is wound onto a third core or mandrel located within the housing in a direction opposite the first direction where it is maintained at about the same predetermined temperature.
