  • Publication number: 20190216493
    Abstract: An apparatus comprises a body assembly, a shaft, an acoustic waveguide, an articulation section, an end effector, and an articulation drive assembly. The shaft extends distally from the body assembly and defines a longitudinal axis. The acoustic waveguide comprises a flexible portion. The articulation section is coupled with the shaft. A portion of the articulation section encompasses the flexible portion of the waveguide. The articulation section comprises a plurality of body portions aligned along the longitudinal axis and a flexible locking member. The flexible locking member is operable to secure the body portions in relation to each other and in relation to the shaft. The end effector comprises an ultrasonic blade in acoustic communication with the waveguide. The articulation drive assembly is operable to drive articulation of the articulation section to thereby deflect the end effector from the longitudinal axis.

  • Patent number: 5939635
    Abstract: The workable range is extended into lower pressure region for micromechanical pressure sensors of the kind having a vibrating mass in proximity of a stationary surface by increasing the amount of squeeze damping. The amount of squeeze damping is increased by using the symmetry of a circular disk-shaped vibrating mass and restricting or changing the flow path of the gas in and out of a squeeze damping space. A circular vibrating mass is supported through an annular spring by a support ring attached to the substrate surface by a plurality of mesas which serve to block the gas flow into and out of the squeeze damping space between the mass and the substrate surface. The amount of squeeze damping may be increased by providing the support ring which completely encloses the squeeze damping space with the vibrating mass having a hole through which the gas may enter and leave the space.

  • Patent number: 5610431
    Abstract: A cover for a micromechanical device through which input/output connections to the device are made. The cover includes at least two doped semiconductor standoffs supporting an insulative layer. One or more metalized vias extend from a top surface of the insulative layer, or from a bottom surface of the base, to a respective standoff. Electrical connection is made to the covered device through the metalized vias and doped semiconductor standoffs. The covered chip may be vacuum sealed by providing a ring-like standoff which borders the covered device when the cover is bonded to the base. The resulting covered chip is adaptable for various chip mounting techniques, including flip chip mounting, side mounting combined with either tape automated bonding (TAB) or conductive epoxy connections, or epoxy chip attachment with wire bonding connections. In one embodiment, conductive bumps are formed on the top surface of the insulative cover layer to accommodate flip chip mounting.

  • Patent number: 5528939
    Abstract: An improved gas pressure gauge is disclosed that extends the linear range of pressure dependent damping to higher pressures by placing a stationary member in very close proximity to the vibrating member. This range of linear dependent damping is also extended to lower pressures by making the vibrating member large in area relative to its small distance from a fixed planar member, which can also serve as its supporting member, by making it vibrate in a direction perpendicular to the fixed planar member, and by making the springs that support the vibrating member from a high Q and conductive material, such as boron doped single crystal silicon. These features for extending the range to higher and lower pressures can be built separately into two independent vibrating elements that can be used individually or in tandem, or they can be built into a single vibrating element that can be made to vibrate in two modes, one parallel and one perpendicular to a fixed member.

  • Patent number: 5224017
    Abstract: A composite heat transfer device is disclosed, for mounting with an object having a predetermined coefficient of thermal expansion, including a composite heat conductive member having a quantity of first and second materials; the first material having a positive coefficient of thermal expansion and the second material having a negative coefficient of thermal expansion. The first and second materials are combined in a quantity ratio to produce a composite heat transfer device with a coefficient of thermal expansion which can be closely tailored to match the predetermined coefficient of thermal expansion of the object with which heat is to be transferred. Also included is a heat transfer assembly including a circuit board on which are located a plurality of heat generating devices. The circuit board is mounted proximate a composite heat conductive member. The composite heat conductive member is mounted proximate a hollow core structure which forms passageways through which may flow a fluid medium.

  • Patent number: 5094013
    Abstract: An ultra-fast quenching device for rapidly quenching material includes a housing for defining a quenching area. A plurality of inlet ports are disposed in the housing and are generally evenly distributed within the housing for controlling the locations and amounts of quenching fluid discharged against a surface of material disposed in the quenching area. A plurality of exhaust ports are disposed interstitially among the inlet ports for removing quenching fluid local to the inlet ports to control the rate and profile of heat transfer, from the material to the quenching fluid, across the surface of the material.

  • Patent number: 4974119
    Abstract: A conforming heat sink assembly including a heat dispersive element is mounted in spaced relationship to a surface from which heat is to be conducted. A thermal interface is provided for coupling the heat dispersive element to the surface from which heat is to be conducted. The thermal interface includes an elastomeric member which occupies only a portion of a volume defined by mounting the heat dispersive element proximate the surface from which heat is to be conducted. The unoccupied volume allows the elastomeric member to easily conform to the irregular surface from which heat is to be conducted to enhance thermal conductivity from the surface to the heat dispersive member.
