Title: Modular jack having a plug-positioning member
Inventor: GOODRICH ROBERT R
IPC: H01R24/58
Filed: 2000-11-20
Granted: 2005-05-17
Abstract: A modular jack [200] includes a jack housing [220] with an opening [225] in its front end that is adapted to receive a modular plug [100]. Within the opening there are a number of jack springs [215] for making electrical contact with metallic blades [120] that are installed in the plug. Variations in the actual position [211] where the plug blades make contact with the jack springs are reduced by the inclusion of a positioning member within the housing. This is extremely important in situations where the modular plug includes crosstalk compensation, since positional variations affect the amount of crosstalk compensation needed. In one embodiment, the positioning member comprises a cam [228] that engages a flexible latch [130] on the modular plug to create an axial force [Fl] that pushes the plug toward a retaining surface [229] within the housing. In another embodiment, the positioning member comprises a spring [213], other than the jack springs, that engages a rigid surface [135] on the modular plug to create an axial force [F2] that pushes the plug toward the fixed retaining surface.

Granted: 2010-10-19
Abstract: A telecommunications system and method is disclosed for providing service transparency for mobile terminating calls to a roaming H.323 mobile terminal. An H.323 mobile terminal can be assigned both an office number and a regular Mobile Station Integrated Services Digital Network (MSISDN) number. The MSISDN of the H.323 mobile terminal will not be made available to the H.323 mobile subscriber or to anyone else. The MSISDN will only be used internally within the Public Land Mobile Network (PLMN) and H.323 system to route the call properly. Thus, whenever a call attempt is made to the H.323 mobile terminal, the call shall always be routed to the H.323 Gatekeeper. If the H.323 mobile terminal has roamed outside the H.323 network, the H.323 Gatekeeper can apply mobile terminating services to the incoming call and route the call to the serving PLMN of the H.323 mobile terminal using the H.323 mobile terminal's MSISDN.

Abstract: The fluid pump of the present invention includes an upper enclosure for holding fluid (typically a liquid) from a fluid input source, and a lower enclosure for outputting the fluid to an output line. A first valve (a) controls the fluid input flow into the upper enclosure. A second valve (b) is engaged in a line between the upper enclosure and the lower enclosure to control the fluid flow from the upper enclosure to the lower enclosure. A second fluid input line is engaged to the lower enclosure to input a second fluid (typically a pressurized gas) into the lower enclosure, and a third valve (d) is engaged in a line between the lower enclosure and upper enclosure to control the flow of the second fluid into the second enclosure. A fourth valve (c) is engaged in a fluid output line to control the flow of the second fluid out of the upper enclosure. In the preferred embodiments, each of valves a, b, c and d is controlled by an automated pump system controller. Various embodiments of th e present invention include further valves and check valves to provide improved control in the system. The preferred embodiment o f the dual chamber pump operates by outputting the liquid from the lower enclosure under a constant, controlled gas pressure. When the liquid level in the lower enclosure is low, the lowerenclosure is filled with liquid from the upper enclosure. To accomplish this, the upper enclosure is pressurized to the same pressure as the lower enclosure, and because the upper enclosure is disposed above the enclosure, the gravitational head causes the liquid in the upper enclosure to flow into the lower enclosure. The upper enclosure is filled during the pump cycle in which the lower enclosure is outputting liquid. The pump thus has a repeatable cycle, although the gas pressure in the lower enclosure remains constant and liquid is constantly output from the pump at a controlled pressure.

Title: Method and apparatus for self-doping contacts to a semiconductor
Inventor: MEIER DANIEL L
IPC: H01L21/228
Filed: 2000-11-22
Granted: 2011-01-04
Abstract: The present invention provides a system and method for creating self-doping contacts to silicon devices in which the contact metal is coated with a layer of dopant and subjected to high temperature, thereby alloying the silver with the silicon and simultaneously doping the silicon substrate and forming a low-resistance ohmic contact to it. A self-doping negative contact may be formed from unalloyed silver which may be applied to the silicon substrate by either sputtering, screen printing a paste or evaporation. The silver is coated with a layer of dopant. Once applied, the silver, substrate and dopant are heated to a temperature above the Ag-Si eutectic temperature (but below the melting point of silicon). The silver liquefies more than a eutectic proportion of the silicon substrate. The temperature is then decreased towards the eutectic temperature. As the temperature is decreased, the molten silicon reforms through liquid-phase epitaxy and while so doing dopant atoms are incorporated into the re-grown silicon lattice. Once the temperature drops below the silver-silicon eutectic temperature the silicon which has not already been reincorporated into the substrate through epitaxial re-growth forms a solid-phase alloy with the silver. This alloy of silver and silicon is the final contact material, and is composed of eutectic proportions of silicon and silver. Under eutectic proportions there is significantly more silver than silicon in the final contact material, thereby insuring good electrical conductivity of the final contact material.

Abstract: A mining machine (7) is provided which moves from side-to-side in sequential passes across a seam of material to be mined. The machine (7) is carried on rail means (19) and co-ordinate positions of the rail means (19) are measured at locations along the length of the rail means. A trailing part of the rail means (19) i s then moved by rail moving means (25) to a new position for a next pass, and the distance of moving is determined from the co- ordinates of the positions previously measured. By knowing the co-ordinates of the positions, the rail means (19) can be moved to assum e a desired profile, so that a desired profile of the face of the seam can be achieved on the next pass of the machine (7). Desirably t he profile is a straight line. Co-ordinates of the up and down movement of a shearing head (9) can also be measured and stored with th e co-ordinates of the positions along the rail means to provide a profile of the seam being cut, and so that on a next pass the intended position of the shearing head (9) can be predicted and moved accordingly. A method of mining embodying the above is also provided.

IPC: B23K26/067
Filed: 2003-01-10
Granted: 2010-05-04
Abstract: A laser beam emitted from a laser source is split by a beam-splitting means such as a beam sampler, and the power Q of the split beam is measured by a first detector. In addition, the power q1 of light that has passed through a pinhole while a DOE is not set is measured by a second detector, and the power ratio .alpha. = q1/Q is calculated. Then, the DOE is set and the power ratio .beta.k = q k/Q, where q k is the power of each light beam, is calculated. The power ratio .beta.k is evaluated on the basis of the power ratio .alpha., so the optical properties of a diffractive optical element, in particular, in terms of diffraction efficiency in laser-beam diffraction and intensity uniformity of split beams can be measured with high accuracy.
