Patent number: 5410257Abstract: An IC test/burn-in socket with spring cantilever beam contacts and a lid 4 that provides for self-aligning of the IC lead and the socket contacts 6. The lid is actuated from above, and the lid has three positions--one for an unloaded socket, one for holding the contacts apart for insertion of an IC, and the other for releasing the contacts such the the spring force of the cantilever beam contacts make electrical contact with the IC leads. The cantilever contacts are arranged in interdigitated rows. The flat cantilever contacts allow the contacts to spread a substantial distance to achieve the desired contact force and will thus accommodate a wider range of IC lead thicknesses and, so, be more forgiving than earlier designs. There is a lid with troughs to guide the contacts and a through hole whereby an IC is inserted. The troughs and through hole provide improved registration of IC lead to socket contacts.Type: GrantFiled: March 15, 1993Date of Patent: April 25, 1995Assignee: Precision Connector Designs, Inc.Inventor: John D. Swaffield

Patent number: 5408181Abstract: A pulsed nmr analysis system for polymers materials extracted from industrial processes at a mobility enhancing temperature (at or above glass transition temperature for amorphous polymers, at the crystalline transition temperature for crystalline and semi-crystalline polymers). The sample is measured via nmr techniques and results correlated to viscosity and melt index or melt flow (which are related to average molecular weights). The nmr system (in or out of resonance) includes: sample throughput system (P, LI, V1, V2) and user system controls (104) to establish digitized free induction decay curves (C), from which components functions are determined using linear or non-linear regression techniques to correlate the curve components to the target nuclei and to flow rates in plastics.Type: GrantFiled: August 30, 1993Date of Patent: April 18, 1995Assignee: Auburn International, Inc.Inventors: Ronald L. Dechene, Thomas B. Smith, David R. Day, Christian I. Tanzer, Scott A. Marino, Ronald J. Tache, Ajoy K. Roy

Patent number: 5396806Abstract: Apparatus and process for measuring mass flow of a slurry mixture of two components of materials, such as a flow of catalyst solid particles (the first component) or droplets in a fluid carrier (the second component). The slurry mixture is added to a process stream (10) or batch reactor. The flow velocity and the volume fraction of one component are measured and combined with the known specific gravity, of the component being measured, and the physical dimensions of the pipe, in which the slurry mixture is flowing, to determine the mass flow of the component. The flow velocity is measured by correlating signals at two separated locations along the flow path, and the volume fraction is measured by combining the known dielectric constants of each of the materials in the mixture and the measured capacitance of the mixture. The capacitance is measured from electrodes which may be isolated from the flowing materials in some applications, but not isolated from the flowing materials in other applications.Type: GrantFiled: November 12, 1993Date of Patent: March 14, 1995Assignee: Auburn International, Inc.Inventors: Ronald L. Dechene, David R. Day, Thomas B. Smith

Patent number: 5350940Abstract: This invention relates to a process for fabricating a metal-oxide-semiconductor device and to the semiconductor device which has enhanced charge mobility due to the inclusion of a thin layer of intrinsic semiconductor which provides a "fast track" charge channel directly at the accumulated inversion layer. The particular semiconductor device described is the enhanced mobility metal-oxide-semiconductor field effect transistor EMMOSFET having the intrinsic layer from about 100 .ANG. to about 1000 .ANG. thick. The intrinsic layer provides a low resistivity channel between the source and drain of the EMMOSFET resulting in an increase in device speed and a decrease in device heat generation.Type: GrantFiled: December 6, 1991Date of Patent: September 27, 1994Assignee: Fastran, Inc.Inventor: Mehmet Rona
