  • Publication number: 20090297595
    Abstract: A device for producing a crosslinked substance, e.g., of crosslinked microcapsules (1) of a crosslinkable capsule substance, in particular crosslinked alginates, is described, having a first dispensing device (2) for dispensing a jet of the crosslinkable capsule substance and a crosslinking device for applying a crosslinking agent to the capsule substance, whereby the crosslinking device has a second dispensing device (5) which directs a jet (9, 13) of the crosslinking agent at the jet or at a layer of the capsule substance.

  • Patent number: 6803301
    Abstract: A fuse configuration for a semiconductor storage device is provided. The fuse configuration includes a first electrode formed in a dielectric layer, the first electrode having a first cross-sectional area defined by a first perimeter; a fuse element, or isolating layer, for coupling the first electrode to a second electrode; and the second electrode having a second cross-sectional area defined by a second perimeter, the first perimeter of the first electrode being larger than the second perimeter. By employing this modified capacitor layout, the fuse element, or isolating layer, will never come into contact with an edge of the first electrode, and thus eliminate a high electric field region from the fuse layout and reliability issues of the prior art fuse configurations. A method for forming the fuse configuration is also provided.

  • Patent number: 6687170
    Abstract: A system and method for determining the accuracy of the states of fuses by changing, or not changing, the state of additional fuses. The system includes a memory including addressable storage elements, address fuses whereby each fuse includes a link in a connected or disconnected state and the collective state of the address fuses identifies an address value, a parity fuse whereby the fuse includes a link in a connected or disconnected state and the state of the parity fuse represents a parity value, the parity value being based on, but not equivalent to, the address of an addressable storage element, and; an output providing a value dependant upon the address value and the parity value.

  • Patent number: 4764473
    Abstract: A chamber for the treatment of cells in an electrical field, in which a space is provided to hold the suspension containing the cells and into which extend at least two electrodes. The cells are exposed to an electrical field developed between the electrodes. The chamber is also provided with an accessory vessel removably connected thereto for further treatment of the cells.

  • Patent number: 4214487
    Abstract: An apparatus for measuring the pressure in a very small volume, such as a ological cell or a capillary vessel. The apparatus has a space or chamber which is connected with a microcapillary tube, is pressure-tight, and is filled with a nearly incompressible medium, such as silicone oil or the like. To measure the pressure in the space, a device for converting the pressure into electrical values is connected to the space. A body, which partially displaces the medium and is moved from outside the space, extends into the space. The apparatus includes a reference electrode and another electrode which is arranged within the microcapillary tube and extends nearly to the opening of the tube. The two electrodes are electrically connected to a control device which is connected with a drive for moving the body which is provided for partial displacement of the medium.
