  • Publication number: 20190252267
    Abstract: A vertical FinFET includes a semiconductor fin formed over a semiconductor substrate. A self-aligned first source/drain contact is electrically separated from a second source/drain contact by a sidewall spacer that is formed over an endwall of the fin. The sidewall spacer, which comprises a dielectric material, allows the self-aligned first source/drain contact to be located in close proximity to an endwall of the fin and the associated second source/drain contact without risk of an electrical short between the adjacent contacts.

  • Patent number: 10364668
    Abstract: A fiber optic sensor is disposed in the elastomer of the stator of the mud motor in order to sense elastomer strain while drilling. The frequencies of micro stalls and stick slips are measured from the fiber optic sensor data by classification using thresholds or by converting time-domain measurements from the fiber optic sensor data to frequencies. For example, the frequencies are produced by accumulating a histogram over an interval of time or by computing a Discrete Fourier Transform over an interval of time. A plurality of fiber optic sensors also can sense angular position of the rotor of the mud motor for correlation of the micro stalls and stick slips with the angular position. The measurements of the micro stalls and stick slips are used to select remedial action such as changes in drilling parameters.

  • Publication number: 20190154081
    Abstract: Downhole tools such as bearing assemblies and stabilizers are described for withstanding abrasive and erosive wear in operation. These stabilizers and bearing assemblies employ wear-resistant hard materials such as TSP, PCD, leached WC, and SCD composite materials. A bond between a braze material and wear tiles constructed of a hard phase material may include a non-planar interface with the braze material. Self-lubricating materials may be provided within the braze material or the hard material in some instances.

  • Publication number: 20190148494
    Abstract: A first vertical field effect transistor (VFET) and a second VFET are formed on a substrate. The VFETs are parallel and adjacent to one another, and each comprises: a fin-shaped semiconductor; a lower source/drain (S/D) element; an upper S/D element; and a gate conductor. A portion of a gate conductor of the second VFET that is positioned over a lower S/D element of the second VFET is removed to leave a trench. An isolation spacer is formed to contact the gate conductor of the second VFET in a first portion of the trench. A lower S/D contact of the second VFET is formed on the lower S/D element of the second VFET in a second portion of the trench, a lower S/D contact of the first VFET is formed to a lower S/D element of the first VFET, and contacts are formed.

  • Publication number: 20180371839
    Abstract: A constant velocity joint for downhole power transmission has a first insert mounted in a radially extending drive shaft arm. The first insert engages a second insert mounted along a slot formed in a tubular housing disposed to receive the arm. The material for the two inserts may be different, having different galling properties. An insert may be shaped to have at least a flat surface, a cylindrical surface intersecting the flat surface, and a conical surface intersecting the cylindrical surface. The inserts may extend beyond the cavities in which they are mounted. Opposing cavity walls adjacent the cavity opening may be angled away from one another to permit the insert to flex under a load. The back wall of a cavity and back surface of an insert may be arcuate to permit rotational movement of the insert under a load.

  • Publication number: 20180338664
    Abstract: The handheld cleaning apparatus provides a handheld cleaning apparatus comprising a removable handle, abrasive particles, angled edges, open channels, and a flexible yet durable surface for scouring. The invention creates an abrasive, or “sanding,” cleaning apparatus that is better suited for cleaning dirty surfaces than a traditional cleaning sponge. The handheld cleaning apparatus retains the abrasive outer shell of a sanding sponge but is much more flexible and water permeable than current sanding sponges. To this end, the handheld cleaning apparatus comprises open channels, or “blow holes,” that promote water flow through the sponge and give the sponge flexibility. The size and the number of the channels vary by the material or density of the sponge. The handheld cleaning apparatus, additionally, contains a handle that is removably attached, which enables the consumer the ability to connect one or more cleaning apparatuses together to form the desired shape and form of the cleaning apparatus.

  • Patent number: 10049858
    Abstract: Systems and methods for protecting vacuum seals in a plasma processing system are provided. The processing system can include a vacuum chamber defining a sidewall and an inductive coil wrapped around at least a portion of the sidewall. A vacuum seal can be positioned between the sidewall of the vacuum chamber and a heat sink. A thermally conductive bridge can be coupled between the sidewall and heat sink. Further, the thermally conductive bridge can be positioned relative to the vacuum seal such that the thermally conductive bridge redirects a conductive heat path from the sidewall or any heat source to the heat sink so that the heat path bypasses the vacuum seal.

  • Publication number: 20180119733
    Abstract: An assembly for use in a wellbore can include a drill string having an outer housing and a thrust bearing sleeve positioned within the outer housing of the drill string. The assembly can also include a stationary thrust bearing positioned within the thrust bearing sleeve and coaxially around a mandrel extending through a longitudinal length of the thrust bearing sleeve. The assembly can further include an interlocking component including a first end coupled to the stationary thrust bearing and a second end positioned in a recessed portion of a housing of the drill string for preventing the stationary thrust bearing from rotating about a central axis of the mandrel, and for allowing the stationary thrust bearing to rotate about one or more axes perpendicular to the central axis. The assembly can include a flexible member for opposing a rotational force applied to the stationary thrust bearing by another thrust bearing.

  • Publication number: 20180073299
    Abstract: A drilling apparatus having a drive section and a bearing section axially distal to the drive section. The bearing section includes a unitary bearing housing defining a bearing housing bore, a driveshaft received within the bearing housing bore and rotatable relative to the bearing housing, and a bearing assembly radially interposed between the bearing housing and the driveshaft for rotatably supporting the driveshaft within the bearing housing bore. The unitary bearing housing may be connected directly with a transmission housing. An axis intersection point between a primary axis of the drilling apparatus and the driveshaft axis may be axially located between a proximal bearing housing end and a distal bearing housing end. One or more stationary bearing components may be non-rotatably engaged with one or more sleeves which are non-rotatably engaged with the bearing housing.
