  • Patent number: 8336215
    Abstract: In an image card where an image is formed on a thin plate made of special synthetic paper or plastic by engraving by sweeping the plate with the engraving needle through relative movement of an engraving needle and a plate, it is impossible to form a hidden image which can be viewed when a viewpoint is changed or form an image formed by watermark engraving and the hidden image within the same plane. A hidden image is formed on an image card by engraving while angles of stripes of striped patterns are changed in response to shading of an image. Further, an image engraving device is provided with a rotary driving unit, and engraving is performed in a state that an extending direction of striped grooves of the hidden image and a forming direction of the engraving are made equal, so that a wall face of a groove is always formed by the same side face of an engraving needle and undulation does not occur on the wall face of the groove. Similarly, a shape of a bottom face of the groove is made even.

  • Patent number: 6340098
    Abstract: The present invention relates to chemical delivery systems and methods for delivery of liquid chemicals. In one embodiment, the present invention relates to systems having multi-reservoir load cell assemblies for delivering chemicals used in the semiconductor industry. In one embodiment, the present invention provides a multi-reservoir load cell assembly, including a controller, a buffer reservoir, a main reservoir, one or more load cells, coupled to the assembly and to the controller, operable to weigh the liquid in the reservoir(s), a plurality of supply lines, each supply line having a valve and connecting one of the supply containers to the main reservoir, and a gas and vacuum sources for withdrawing the liquid from the assembly when demanded by the controller and for refilling the assembly from the supply containers.
