20080211157 | COMPRESSION CLAMPING OF SEMICONDUCTOR COMPONENTS - The present invention relates to a clamping device for compression clamping of one or more semiconductor devices and associated semiconductor components with a desired compression force equally distributed across the opposing surfaces of the devices and associated components. The semiconductor devices and components are located between opposing jaws that are joined together by at least two tie rods, which compressively load the opposing jaws to apply the desired compression force to the semiconductor devices and components. The desired compression force is first achieved in even distribution between independent clamp pressure set point assemblies and the first jaw, where each of the independent clamp pressure set point assemblies is associated with one of the tie rods. Upon final assembly of the clamping device the desired pressure force is achieved across the semiconductor devices and components by compression of the opposing jaws between the one or more semiconductor devices and associated semiconductor components until the clamp pressure indicator elements associated with each of the clamp pressure set point assemblies indicates the desired compression force has been applied. | 09-04-2008 |
20080251233 | INTEGRATED PROCESS CONTROL SYSTEM FOR ELECTRIC INDUCTION METAL MELTING FURNACES - An integrated process control installation is provided for electric induction metal melting furnaces with variable furnace states. The integrated process control installation can include supporting charge delivery and slag removal installations, and furnace process operations for process control of melting metal in the furnaces. The variable furnace states, supporting installations, and furnace process operations are controlled by a supporting processing installation, while a robotic apparatus performs the furnace process operations. | 10-16-2008 |
20100163550 | Heating and Melting of Materials by Electric Induction Heating of Susceptors - Apparatus and method are provided for heating and melting of materials by electric induction heating of susceptor components in a crucible of the furnace. The susceptor components comprise at least an array of susceptor rods arranged around the inner perimeter of the crucible. A susceptor base may also be provided in the crucible with connection to one end of the susceptor rods. One or more susceptor tubes may also be used within the interior volume of the crucible. Alternating current flow through one or more induction coils surrounding the exterior of the crucible generate magnetic flux fields that couple with the susceptor components to inductively heat the susceptor components. Heat from the susceptor components transfers to the material in the crucible to heat and melt the material. | 07-01-2010 |
20120192392 | Compression Clamping of Semiconductor Components - The present invention relates to a method of clamping a semiconductor assembly with a desired compression force equally distributed across the opposing surfaces of the devices and associated components of the semiconductor assembly. | 08-02-2012 |
20120300806 | Electric Induction Furnace with Lining Wear Detection System - An electric induction furnace for heating and melting electrically conductive materials is provided with a lining wear detection system that can detect replaceable furnace lining wear when the furnace is properly operated and maintained. | 11-29-2012 |
20120325867 | Molten Metal Holding and Pouring Box with Dual Pouring Nozzles - A molten metal holding and pouring box with a rectangular-shaped upper section and a pyramidal-shaped lower section provides a relatively constant flow of molten metal being poured from the box through each of two bottom nozzles into two separate foundry molds at the same time. The two bottom nozzles are contained in a unitary dual nozzle assembly that facilitates replacement as required by wear, or a change in location of the sprue cups in the two separate foundry molds being filled with molten metal. | 12-27-2012 |
20140373543 | Electric Induction Fluid Heaters for Fluids Utilized in Turbine-Driven Electric Generator Systems - A fluid latent heat absorption electric induction heater is provided for raising the temperature of a fluid supplied to a fluid-driven turbine in a turbine-driven electric power generation system. The fluid latent heat absorption electric induction heater alternatively transfers heat to the fluid by induced susceptor heating, or a combination of inductor Joule heating and induced susceptor heating. The fluid may be water-steam for powering a steam-driven turbine or another fluid used in a phase change system for driving a fluid-driven turbine in a turbine-driven electric power generation system. | 12-25-2014 |
20150273580 | Clean Cell Environment Roll-Over Electric Induction Casting Furnace System - A clean cell environment for a continuous roll-over electric induction batch casting furnace system is provided where each combination of batch charge, for example an ingot, induction melting (ingot-melt) process and mold-pour process are performed in a clean cell environment and each combination ingot-melt and mold-pour process is traceable as to the identity of the specific ingot, or other charge form (composition) and the mold (fabrication identifier). | 10-01-2015 |
