  • Publication number: 20220371215
    Abstract: A method of determining a cutter height on a wedge bonding machine is provided. The method includes the steps of: (a) lowering a wedge bonding tool toward a surface on the wedge bonding machine; (b) determining a first height measurement when the wedge bonding tool contacts the surface; (c) lowering a cutter of the wedge bonding machine, relative to the wedge bonding tool; (d) determining a second height measurement when the cutter contacts the surface; and (e) determining a cutter height using the first height measurement and the second height measurement.

  • Publication number: 20160248628
    Abstract: A computing or controlling apparatus includes a remote direct memory access (RDMA) adapter device. Responsive to an initialized state, a create queue pair adapter device command is provided by a host processing unit. The adapter device processes the command to create a queue pair in the initialized state. Responsive to a ready to send (RTS) state, a queue pair state transition command is provided by the host processing unit. The adapter device processes the queue pair state transition command to transition the queue pair from the initialized state to the ready to send (RTS) state skipping over the ready to receive (RTR) state. However, if the adapter device processes a ready to receive (RTR) in-band RDMA WQE received from the host processing unit, the state of the queue pair transitions from the initialized state to the RTR state.

  • Patent number: 8424688
    Abstract: A multipolymeric mixture is provided that includes a hydrophobic polymer, two different grades of a water-soluble polymer, water as non-solvent and a solvent suitable for all polymers involved. The dissolved hydrophobic polymer has the affinity to enmesh the water-soluble polymers to form a clear and viscous dope. Water-soluble polymers contribute to the pore formation process and hydrophilicity of the finally coagulated membrane according to the makeup of their molecular weight distribution. Water as a non-solvent takes the dope very near towards unstable zone, which helps in speeding up the membrane formation process in a diffusion induced phase inversion technique. The dope is then spun through a concentric orifice spinneret and solidified by passing it through a coagulation bath to form hollow fiber asymmetric membranes of ultra filtration grade with superior water permeability and separation characters even at higher feed turbidity.

  • Patent number: 7705061
    Abstract: This invention presents an ion exchange media including a plurality of cation exchange zones and anion exchange zones in flow paths that are contained in a substantially nonporous resin transport framework. During electrodeionization and other potential applications the ion exchange media of the invention prevents unfavorable water splitting at resin-membrane interfaces and encourages water splitting at resin-resin interfaces where the water splitting may be constructively used to regenerate the resin.

  • Patent number: 7338600
    Abstract: A liquid treatment process is described for sequential removal of ionic species of progressively decreasing ionic strength without precipitation or “scaling.” An aspect of the invention includes two or more electrodeionization operations within one or more electrodeionization stacks. The first electrodeionization operation is performed at a voltage calculated to remove strongly ionized species such as calcium and magnesium from the feed water without scaling. The product of the first electrodeionization operation is then subjected to a second electrodeionization operation. The second electrodeionization operation is performed at a voltage the same as the first electrodeionization operation, and is designed to remove more weakly ionized species such as silica and carbon dioxide, preventing scaling. More than two successive electrodeionization operations may be performed if desired. Multiple electrodeionization operations may occur in a single electrodeionization stack or in multiple electrodeionization stacks.

  • Publication number: 20050121397
    Abstract: A liquid treatment process is described for sequential removal of ionic species of progressively decreasing ionic strength without precipitation or “scaling.” An embodiment of the invention includes dual electrodeionization operations. The first electrodeionization operation is performed at a voltage calculated to remove strongly ionized species such as calcium and magnesium from the feed water without scaling. The product of the first electrodeionization operation is then subjected to a second electrodeionization operation. The second electrodeionization operation is performed at a voltage greater than the first electrodeionization operation, and is designed to remove more weakly ionized species such as silica and atmospheric carbon dioxide.
