An improved seal member is provided as a part of an electrochromic device to bond two glass elements together in a spaced-apart relationship. In one embodiment the seal member provides improved adhesion to a reflector/electrode on the third surface of an electrochromic mirror, or to a layer of metal on the second or third surface for an electrochromic light filter. This seal member comprises a mixture of an organic resin sealing system and an adhesion promoter, where the adhesion promotor comprises a first and a second region, where the first region interacts with the reflector/electrode or the metal layer, and a second region that interacts with the organic resin sealing system, and may even chemically react with the organic resin sealing system. In another embodiment the seal member is provided with a coefficient of thermal expansion that is closer to glass than a standard epoxy sealing system.

Structures and methods of manufacturing are disclosed of dislocation free stressed channels in bulk silicon and SOI (silicon on insulator) CMOS (complementary metal oxide semiconductor) devices by gate stress engineering with SiGe and/or Si:C. A CMOS device comprises a substrate of either bulk Si or SOI, a gate dielectric layer over the substrate, and a stacked gate structure of SiGe and/or Si:C having stresses produced at the interfaces of SSi(strained Si)/SiGe or SSi/Si:C in the stacked gate structure. The stacked gate structure has a first stressed film layer of large grain size Si or SiGe over the gate dielectric layer, a second stressed film layer of strained SiGe or strained Si:C over the first stressed film layer, and a semiconductor or conductor such as p(poly)-Si over the second stressed film layer.

An SMA actuation apparatus comprises a camera lens element supported on a support structure by a plurality of flexures. An SMA wire at an acute angle to the movement axis and a biasing element are connected between the support structure and the movable element. A component of the force applied by the SMA wire perpendicular to the movement axis compresses the flexures causing them to apply a force to the movable element having a component along the movement axis in the same direction as the SMA wire. An end-stop limits the movement of the movable element, and the moment applied by the end-stop to the movable element about the center of stiffness is equal to the moment applied by the SMA wire about the center of stiffness at the point when the movable element loses contact with the end-stop on contraction of the SMA wire.

The invention comprises a product. The product comprises a foam insulating panel, the panel having a first primary surface and an opposite second primary surface, wherein the foam insulating panel defines at least one recessed channel in the first primary surface, the at least one recessed channel being sized and shaped to provide a mold for a structural reinforcing member. The product also comprises a concrete panel formed on the first primary surface and filling the at least one recessed channel so as to provide a structural reinforcing member for the concrete panel. The product further comprises an elongate anchor member in the foam insulating panel and extending from the first primary surface of the foam insulating panel into the concrete panel. A method of making a composite reinforced insulated concrete structure is also disclosed.

A gasket (10) is provided for an evacuation head assembly (20) to evacuate a chamber (104) defined by two glass sheets (101, 102). The gasket (10) may be made from a metal foil such as aluminium and has opposite sealing surfaces (14, 15, 19) that are profiled with a series of fine grooves (17) and wherein the variation in thickness between the sealing surfaces is less than 1 μm.

The invention provides a method and apparatus for the detection of charge density distribution at the surface of a material sample. The apparatus comprises an electric potential sensor for measuring surface charge on a material sample, wherein the electrical potential sensor includes a probe for capacitively coupling the electric potential sensor to the surface of the material sample, an amplifier for generating a measurement output, the probe being connected to an input of the amplifier and the measurement output being supplied at an output of the amplifier, and a feedback arrangement driven from the output of the amplifier for enhancing the input impedance of the amplifier. A positioning system mounts the probe of the electric potential sensor above the material sample and moves the probe at a constant height over a surface of the said sample, and a processing system receives and processes the measurement output of the electric potential sensor for generating a digital record of the charge density distribution at the surface of the material sample.

A stator assembly structure for an axial flux electric machine is designed. The back iron for each silicon steel disk stator is formed into a specific structure with tooth-like protrusions for allowing the same to be integrated with the disk-type stator seat, while the disk-type stator seat is made of a material suitable for casting or mold forming. A coil is mounted on the disk stator, and a stator assembly is achieved by integrating the stator, the coil and the stator seat. The stator and the disk-type stator seat of the stator assembly are manufactured by using a one-piece cast or one-piece mold forming method so as to enable the contact surfaces of the stator and the stator seat to engage with each other even more tightly, and consequently enable the heat generated from the coil to be transmitted rapidly from the disk stator to the disk-type stator seat.

A semiconductor device includes a MIS transistor having a gate electrode which is fully silicided with metal. The edge parts of the gate electrode are lower in height than the other part thereof. Sidewall spacers are formed to cover the side and top surfaces of the edge parts of the gate electrode.

The invention provides a method and apparatus for producing uniform, isotropic stresses in a sputtered film. In he presently preferred embodiment, a new sputtering geometry and a new domain of transport speed are presented, which together allow the achievement of the maximum stress that the film material can hold while avoiding X-Y stress anisotropy and avoiding stress non-uniformity across the substrate.

A piezoelectric power generator that includes a support body, a piezoelectric element, and a bias compressive stress applying member. The piezoelectric element is placed on the support body. The piezoelectric element has a piezoelectric plate that is polarized in the thickness direction, and first and second electrodes that are each provided on a surface of the piezoelectric plate. The bias compressive stress applying member is supported on the side above the piezoelectric element by the support body. The bias compressive stress applying member applies to the piezoelectric element a bias compressive stress acting in the thickness direction of the piezoelectric plate, so that the magnitude of a compressive stress in the piezoelectric plate changes with a change in externally applied stress.

A method of manufacturing an impeller including a substantially disk-shaped disk, a cover facing the disk, and a blade provided between the disk and the cover, the method includes: forming a groove in a blade attachment surface of the disk or the cover so as to correspond to the shape of an edge tip of the blade; and bonding an inner surface of the groove to the edge tip of the blade through a bonding agent after inserting the edge tip of the blade into the groove.

The present invention is generally directed toward an artificial fishing lure component. In particular the present invention is directed toward a fishing lure component simulating a worm's head, which may be used as a slip sinker, a pegged sinker, or simply as an addition to a traditional, artificial worm lure to facilitate the natural movement of live bate in weeds, brush, twigs, and stone. The present invention is conically shaped and composed of soft flexible material with a cavity for snugly encapsulating a weighted sinker. The present invention may be used in a variety of configurations including both Texas and Carolina Rigs.
