  • Patent number: 6451121
    Abstract: Thermally-inhibited starches and flours which are functionally equivalent to chemically-crosslinked starches are prepared by a process which comprises the steps of dehydrating a granular starch or flour to anhydrous or substantially anhydrous (<1% moisture) and heat treating the dehydrated starch or flour for a time and at a temperature sufficient to inhibit the starch, (e.g., 120-180° C. for up to 20 hours). Preferably the pH of the starch is adjusted to neutral or greater (e.g., pH 8-9.5) prior to the dehydration. The dehydration may be a thermal dehydration carried out simultaneously with the heat treatment or a non-thermal dehydration carried out by extraction with a solvent (e.g., ethanol) or by freeze drying.

  • Patent number: 6434048
    Abstract: A method and circuit write a memory cell. The method applies a pulse train to a write line connected to the memory cell. The number of pulses in the pulse train is not predetermined. The method compares a value on the input side of the cell to a reference value, wherein the input side of the memory cell provides an indication that a writing operation is complete. The method discontinues the pulse train on the write line, in response to the comparing step, preferably if the value on the write line exceeds the reference value. Preferably, the pulses are short in width and large in magnitude. The method may optionally count the number of pulses in the pulse train, and discontinue the pulse train on the write line and/or declare the cell as unusable if the number of pulses exceeds a predetermined maximum. The circuit comprises a pulse train generator and a comparator. The pulse train generator has an output and an enable input. The output is connected to a write line connected to the memory cell.

  • Patent number: 6422148
    Abstract: A perforating gun assembly that includes at least one component that is constructed from a composite material and that is impermeable to wellbore fluids. The components may include the outer carrier and/or loading tube of a perforating gun, the connecting tubing of a gun release mechanism, and the gun connector used to attach adjacent perforating guns. The composite material is designed to be very brittle under dynamic impact. The component is made impermeable to wellbore fluids by including an impermeable liner therein. The impermeable liner can be bonded to the inner or outer surface of the component or can be embedded within the component. Since it is brittle under dynamic impact, the composite component shatters into small pieces upon detonation of the perforating gun.

  • Patent number: 6415193
    Abstract: A universal recipe editor is for off-line viewing and editing of semiconductor-manufacturing recipes. The universal recipe editor can read recipes from a wide variety of semiconductor-manufacturing machines from different manufacturers using recipe distributed object model (R-DOM) files. An R-DOM file is generated for each kind of recipe-file format to locate process parameters within proprietary recipe-file formats. The sequence of parameters in the R-DOM file matches the sequence in the recipe data file so that parameters may be mapped from recipe data files for display and editing. ASCII or binary recipe file formats are mapped from the recipe data file using R-DOM objects. Revision and authoring information is kept in a recipe information file for each recipe. Each line of the recipe data file can specify a different process parameter. Security or access rights for each parameter is added for each parameter by including security codes on each line in the R-DOM file.

  • Patent number: 6404674
    Abstract: A magnetic memory cell having read-write conductor that is wholly clad with a high magnetic permeability soft magnetic material for a pinned-on-the-fly soft ferromagnetic reference layer is disclosed. The magnetic memory cell includes a ferromagnetic data layer, an intermediate layer formed on the ferromagnetic data layer, and a soft ferromagnetic reference layer having a non-pinned orientation of magnetization formed on the intermediate layer. The soft ferromagnetic reference layer includes a read-write conductor and a ferromagnetic cladding that completely surrounds the read-write conductor to form a cladded read-write conductor. During a read operation, a read current flowing through the read-write conductor generates a read magnetic field that does not saturate the ferromagnetic cladding. During a write operation, a write current flowing through the read-write conductor generates a write magnetic field that saturates the ferromagnetic cladding and extends to the ferromagnetic data layer.

  • Patent number: 6381738
    Abstract: Information is computed about the reachability relationships among objects and pointers to enable transformation of a computer program for optimizing the creation and destruction of objects, while strictly performing the semantics of the original program. An interprocedural analysis is used to determine whether an object that is allocated on the heap during the execution of a procedure is not reachable from any global variable, parameter, or the return value of the procedure after it returns. If so, that object can be allocated on the stack frame of the procedure in which it is otherwise heap-allocated. This simplifies the memory allocation and deallocation operations, as allocation on the stack can be done more efficiently than allocation on the heap, and objects allocated on the stack frame of a procedure are automatically deallocated when the procedure returns, without incurring the overhead of garbage collection.
