A method of removing clay compounded on drilling equipment in a well that includes contacting the drilling equipment with a treatment fluid comprising an oxidizing agent. Methods disclosed also relate to drilling a wellbore though a clay-containing formation that includes drilling through the formation with a water-containing drilling fluid; reducing applied weight-on-bit when bit balling detected; emplacing a treatment fluid comprising an oxidizing agent to disrupt clay compounded on drilling equipment; and increasing weight-on-bit to continue drilling through the formation

A water based drilling fluid for use in drilling a subterranean well through a subterranean formation that swells in the presence of water, the drilling fluid is formulated to include: an aqueous based continuous phase; a weight material; an optional shale hydration inhibition agent and a shale encapsulator. The shale encapsulator has the formula: in which x and y have a value so that the molecular weight of the cation is in the range of about 10,000 to about 200,000 AMU; A is selected from C1-C6 alkyl, C2-C6 ether or C2-C6 amide; R, R′ and R″ are independently selectable C1-C3 alkyl; and B− is a charge balancing anion to the quatenary amine. The shale hydration inhibition agent and the shale encapsulator may be present in sufficient concentrations to reduce the swelling of the subterranean formation in the presence of water. Conventional additives may be included into the formulation of the drilling fluid, including: fluid loss control agents, alkaline reserve and other pH control agents, bridging agents, lubricants, anti-bit balling agents, corrosion inhibition agents, surfactants, solids suspending agents, and mixtures and combinations of these and other similar additives.

A method for minimizing fabrication defects in ballast contact to a conductor in monolithically integrated semiconductor devices includes forming a sloping sidewall (318, 424) in both an insulating layer (106, 718) overlying a conductive layer (104, 714) by etching with a an RF biased fluorine based chemistry and an RF biased chlorine based chemistry, respectively, as defined by a single resist layer (108) having a sloped sidewall (212). A ballast layer (526, 726) is deposited on the structure (100, 700) and metal contacts (632, 634, 636, 638, 722) are disposed on the ballast layer (526, 722).

A welding stock storage rack made from wire mesh bent to form a pyramid has a trapezoidal cross section and planar, vertical ends. The wire mesh comprises elongate strands of steel wire laid in a rectangular grid and welded at each intersection to form a panel of regular, individual cells. Additional wire mesh forms end panels, completing a geometrically stable, three-dimensional structure. Welding stock of various types and sizes may be inserted longitudinally, transversely or both through the pyramid to be supported horizontally at various levels above the floor by opposing cells. Several of the racks may be concatenated end to end to form a longer rack for lengthier welding stock, and the racks may be nested when empty for inventorying, storage and transportation.

An FPGA is laid out as a plurality of repeatable tiles, wherein the tiles are disposed in columns that extend from one side of the die to another side of the die, and wherein each column includes tiles primarily of one type. Because substantially all die area of a column is due to tiles of a single type, the width of the tiles of each column can be optimized and is largely independent of the size of the other types of tiles on the die. The confines of each type of tile can therefore be set to match the size of the circuitry of the tile. Rather than providing a ring of input/output blocks (IOBs) around the die periphery, IOB tiles are disposed in columns only. Where more than two columns worth of IOBs is required, more than two columns of IOB tiles can be provided.

A method and apparatus are provided for identifying analytes at low concentrations in a liquid sample. The liquid sample is introduced through a continuous flow membrane inlet system. The analytes that permeate the membrane are analyzed by photoionization-time-of-flight mass spectrometry. The analytes remaining in the liquid sample that do not permeate the membrane are conducted to a capillary tube inlet that introduces the liquid sample and other analytes as droplets into the photoionization zone. Any analytes remaining absorbed or adsorbed on the membrane are driven through the membrane by application of heat. Analytes may be analyzed by either resonance enhanced multiphoton ionization (REMPI) or single photon ionization (SPI), both of which are provided in the apparatus and can be selected as alternative sources.

Interconnecting logic provides connectivity of an embedded fixed logic circuit, or circuits, with programmable logic fabric of a programmable gate array such that the fixed logic circuit functions as an extension of the programmable logic fabric. The interconnecting logic includes interconnecting tiles and may further include interfacing logic. The interconnecting tiles provide selective connectivity between inputs and/or outputs of the fixed logic circuit and interconnect of the programmable logic fabric. The interfacing logic, when included, provides logic circuitry that conditions data transfers between the fixed logic circuit and the programmable logic fabric. In one operation, the programmable logic fabric is configured prior to the startup/boot sequence of the fixed logic circuit. In another operation, the fixed logic circuit is started up and is employed to configure the programmable logic fabric.
