  • Patent number: 6171820
    Abstract: Disclosed is a rapid and facilitated method of producing from a parental template polynucleotide, a set of mutagenized progeny polynucleotides whereby at each original codon position there is produced at least one substitute codon encoding each of the 20 naturally encoded amino acids. Accordingly, there is also provided a method of producing from a parental template polypeptide, a set of mutagenized progeny polypeptides wherein each of the 20 naturally encoded amino acids is represented at each original amino acid position. The method provided is termed site-saturation mutagenesis, or simply saturation mutagenesis, and can be used in combination with other mutagenization processes, such as, for example, a process wherein two or more related polynucleotides are introduced into a suitable host cell such that a hybrid polynucleotide is generated by recombination and reductive reassortment.

  • Patent number: 6167195
    Abstract: A system for rapid thermal processing of a substrate in a process chamber while measuring and controlling the temperature at the substrate to establish substantially uniform substrate temperature in real time. The system includes an essentially continuous spirally-configured multizone illuminator having a plurality of substantially concentric rings of heating lamps for directing optical power toward the substrate and a fluid cooled optical reflector facing the substrate frontside and having a relatively high optical reflectivity. The illuminator can also be offset from the geometric center of the substrate. The system can also include a plurality of contact devices to provide thermal conductivity from each, or some subset, of the plurality of heating lamps. The illumination system of the present invention provides improved spatial resolution and improved thermal properties at the heating lamps.

  • Patent number: 6111406
    Abstract: A method for assessing write element performance in a combined magnetic head that also includes a magneto-resistive (MR) read element for a data storage drive includes exciting the write element with a square wave immediately after lapping the head during manufacture, before mounting the head for operation in the drive. The write element generates an output signal, and the output signal is detected by the read element and then used to determine whether the write element is defective. By using a square wave, temperature gradients in the head and inductive pick up is avoided, thereby facilitating the use of the read element as a test sensor.

  • Patent number: 6104576
    Abstract: An inductive magnetic head is provided which has a zero throat height (ZTH) defining insulation layer that is located entirely between the air bearing surface (ABS) and a coil layer of the head. The ZTH defining insulation layer has a front end which defines the zero throat height (ZTH) of the head. An insulation stack, with one or more coil layers embedded therein, is located between the ZTH defining insulation layer and a back gap where first and second pole pieces are connected. The insulation stack has a first insulation layer that has a thickness that is less than the thickness of the ZTH defining insulation layer so that the final stack has less height than previous insulation stacks. The lower stack permits the construction of a second pole piece pole tip portion with improved side wall definition.

  • Patent number: 6081409
    Abstract: A magneto-resistive read head having a "parasitic shield" provides an alternative path for currents associated with sparkovers, thus preventing such currents from damaging the read head. The parasitic shield is provided in close proximity to a conventional magnetic shield. The electrical potential of parasitic shield is held essentially equal to the electrical potential of the sensor element. If charges accumulate on the conventional shield, current will flow to the parasitic shield at a lower potential than would be required for current to flow between the conventional shield and the sensor element. Alternatively, conductive spark gap devices are electrically coupled to sensor element leads and to each magnetic shield. Each spark gap device is brought within very close proximity of the substrate to provide an alternative path for charge that builds up between the sensor element and the substrate to be discharged.

  • Patent number: 6069654
    Abstract: This invention relates to a system and method for far-field determination of store position and attitude for separation and ballistics. The aircraft is outfitted with two photogrammetric video cameras. The store is dropped from the aircraft and the cameras record data describing the descent of the store while the on-board avionics record data describing the flight path of the aircraft. Following the flight, the data are correlated using a computer to obtain a true store position vs. time while separating from the aircraft.

  • Patent number: 5999286
    Abstract: This invention includes a path-based method and system that restore a distributed telecommunications network (90) from a failure condition (92). First, the method and system notify all the network nodes (22, 24, 26, 28) of the fault of a link (12). Next, an alternate route finding phase occurs for finding alternate paths (S-T1-T4-D) to reroute the disrupted traffic. For finding alternate paths (S-T1-T4-D), the alternate route finding phase includes sending messages (70, 100) throughout the distributed telecommunications network. Upon finding some alternate paths (S-T1-T4-D), the method and system send connect commands (100) to make the necessary cross connections in the distributed telecommunications network nodes (22, 24, 26, 28) that are on the alternate paths (S-T1-T4-D). Throughout the distributed network restoration process, the method and system synchronize (62) the distributed telecommunications network nodes to avoid possible race conditions among the nodes.
