  • Publication number: 20020031477
    Abstract: The present invention provides an integrated structural unit that includes a diagnostic form that includes at least one active ingredient that is present in an amount that advantageously does not vary by more than about five percent from a predetermined target amount. In one embodiment, the unit form comprises a substrate, a deposit that is disposed on the substrate, and a spreading layer that overlies the deposit and is used to retain and spread a sample of liquid which is to be assayed. The deposit comprises a powder, including the active ingredient(s). The diagnostic form is created via a dry powder deposition apparatus that electrostatically deposits the powder on the substrate utilizing an electrostatic chuck and charged powder delivery apparatus.

  • Patent number: 6221438
    Abstract: A display structure is formed using patterned deposition of display materials. A substrate includes a plurality of distinct electrodes. A plurality of droplets including a material are formed and charged to a second polarity. First selected ones of the plurality of electrodes are charged to a first polarity opposite the second polarity to selectively attract the droplets including the material to the oppositely charged first selected ones of the plurality of electrodes.

  • Patent number: 5925203
    Abstract: A plasma display includes a front panel having a glass body secured to a surface of a substrate. The glass body has a plurality of channels in the exposed surface thereof with upstanding ribs being between the channels. Conductive first electrodes are on the body with each electrode extending along the bottom of a separate channel. The first electrodes are preferably embedded in the glass body. A transparent front panel is over the back panel and is seated on and secured to the glass body. A plurality of spaced, parallel second electrodes extend between the front panel and the back panel substantially orthogonally to the first electrodes. Phosphors which emit different colors are coated on the channels and the channels are filled with a plasma gas.The back panel is formed of at least one and preferably a plurality of layers of a green tape of glass particles in a binder. The layers are stacked one on top of each other and the channels are formed in the surface of one of the layers.
