A light emitting device has: a light emitting element; a lead that is electrically connected to the light emitting element at its one end and serves as a terminal to supply a power source to the light emitting element; a metal base that the light emitting element is mounted thereon and radiates heat of the light emitting element; and a sealing member that is of transparent resin or glass and covers the light emitting element. The lead is secured to the metal base by a heat-resisting insulating member with a thermal expansion coefficient nearly equal to that of the metal base.

A system for heating at least a part of a subsurface hydro carbonaceous earth formation forms a borehole into or adjacent to the formation, places elongated coaxial inner and outer conductors into the borehole with the inner and outer conductors electrically connected to each other at a depth below the top of the formation, and connects an AC power source to at least the outer conductor to produce heat in at least one of the conductors. The AC output has a controlled frequency, and the outer conductor comprises a standard oil well component made of a ferromagnetic material that conducts current from the AC power source in only a surface region of the conductor due to the skin effect phenomenon. More heat is dissipated from portions of the conductor that is within the depth range of the formation than from other portions of the conductor. The inner conductor may optionally be a standard tubular oil well component made of a ferromagnetic material that conducts current from the AC power source in only a surface region of the conductor due to the skin effect phenomenon.

Techniques are disclosed that enable extrusion detection (i.e., outgoing confidential information from an enterprise or other entity). The techniques operate to detect outgoing confidential information at the gateway and/or the client, even if that confidential information is encrypted, compressed, or otherwise obfuscated before transmission (e.g., via email or to a portable storage media such as a memory stick).

The present invention provides a system and method for using a liner in conjunction with the cage of a bottle and cage type IBC. The invention involves use of a support that is placed inside the cage of a bottle and cage type IBC. In one embodiment, the support may be a thin sheet of material that conforms to the inner surface of the cage. In an alternative embodiment, the support may be a bottle from a cage and bottle type IBC that has been modified by removing the discharge valve spout. In the case that a liner is used in conjunction with the cage, the support forms a barrier between the liner and the cage to prevent the liner from extruding through the bars of the cage. An aperture in the support may allow a discharge valve of a liner to extend outwardly for easy access to the item.

A method and structure for a semiconductor chip includes a plurality of layers of interconnect metallurgy, at least one layer of deformable dielectric material over the interconnect metallurgy, at least one input/output bonding pad, and a support structure that includes a substantially rigid dielectric in a supporting relationship to the pad that avoids crushing the deformable dielectric material.

An access panel for providing access to cables, services or the like through an opening in a floor having a floor covering, is disclosed. The access panel includes a floor frame (10) located in the opening and a lid (100) supported on the frame (10). The frame (10) has a support flange (26) extending around its periphery which extends between the floor covering and the floor deck. The flange (26) provides a ramped edge tapered substantially uniformly over a distance of between 10 and 20 times the maximum thickness of the flange (26). The outermost part of the flange (26) is typically formed from a flexible polymeric material. A rib (20) extends around an aperture in the frame (10) and the height of the rib (20) is lower than the load bearing surface of the floor. The hinge (24, 120) is generally square and defines a pivot surface which extends parallel to and is spaced inwardly from an inner edge of the frame (10). A lid (100) for closing the aperture defines a bearing surface (120) which is adapted to slidably engage on the pivot surface (24) to allow the lid (100) to bear and pivot about the pivot surface (24). The lid (100) includes hatches (104, 106) which are moveable between an open position in which there is an aperture in the lid (100) through which cable services may extend and a closed position in which there is no aperture. Locking means (124, 126) are provided between the hatch (104, 106) and the frame (10) to lock the hatch (104, 106) in place in both the open and closed positions.

A gel-filled seismic streamer containing a hydroplane housing which isolates a hydrophone element from shear waves and mechanical forces but sensitive to pressure waves. In one embodiment, the gel-filled streamers contains a hydrophone housing with an air pocket at each end for isolating a pressure sensitive hydrophone element from mechanical noise generated by cable movement during seismic data acquisition operations. The hydrophone housing further provides a protective case to isolate a pressure-sensitive hydrophone element from shear waves. An inlet formed in the protective hydrophone housing enables pressure waves to be communicated to the pressure sensitive hydrophone element inside of the housing. In one embodiment, the pressure sensitive hydrophone element is a hollow gel-filled cylinder that expands radially outward into a second air gap formed in the housing. A protective case is also provided to isolate the hydrophone housing from shear waves. An alternative hydrophone housing for deployment inside of a streamer is also disclosed which fixably positions a positioning hydrophone or seismic hydrophone within the housing using rubber supports.

A thermosetting foam, preferably a polyurethane foam is prepare by mixing all the components in one or more extruders and directing the chemical streams to a mixing head where the catalyst is added. Thus, the reaction can be controlled in a facile manner, whereby clogging of the extrusion head is avoided.

A temperature controlled storage apparatus 8(10), comprising; a plurality of lockable storage spaces, each of the plurality of lockable storage spaces comprising one or more compartments; in which the temperature of each of the one or more compartments is independently controllable to provide either one of: chilled temperature; or frozen temperature; and wherein access to the storage space is remotely programmable.

A retrievable well plug has a through shaft (12) with link connections (62, 64) and a packer element (66). By pushing the link connections (62, 64) and the packer element towards each other, the link connections (62, 64) and the packer element (66) expand radially, such that a mechanical barrier for the packer element (66) is formed. The links (76; 174, 176) have a generally T-shaped cross sectional profile and include an arm (78) with an end (80) meant for fastening to the fastening devices (72, 74). The other end of the arm (78) fastens to the second link (77) of the link connection (62, 64). Upper supporting surfaces (84, 86; 184; 192, 194) of the links (76; 174, 176) form an approximately tight mechanical barrier against the packer element (66) in an expanded position. The anchoring device (20) has a number of gripping devices (22), wherein the gripping devices (22) at setting of the well plug (10) expand radially, thereby providing an anchoring of the well plug (10) to the well bore wall.

A curved bur with an inner flexible member that is rotatably positioned within an outer tube. The curved bur has a design that constrains the flexible inner coil within the outer tube as the curved bur is rotated (without permitting the coil to stretch and to allow the bur tip to come out of the distal end of the outer tube). To ensure containment of the flexible coil within the outer tube, the outer tube is provided with a constraining neck feature at its distal end to allow the flexible inner assembly to be constrained within the outer tube, and to prevent bur extrusion. The constraining neck feature also centers the bur tip and prevents bur wobble. The curved bur may have a convex or concave bend configuration.
