Concept Search - What can I type?
For a concept search, you can enter phrases, sentences, or full paragraphs in English. For example, copy and paste the abstract of a patent application or paragraphs from an article.
Concept search eliminates the need for complex Boolean syntax to inform retrieval. Our Semantic Gist engine uses advanced cognitive semantic analysis to extract the meaning of data. This reduces the chances of missing valuable information, that may result from traditional keyword searching.

Static Proof Semiconductor Carrier
The figure shows two semiconductor carrier tubes 10 and 11 which are
designed for the carrying of semiconductor modules, both packaged and
The carrier is specifically designed to provide support for the main body of
pins 13 of the module while permitting the longer outboard corner pins 14 to ride
free, thus preventing damage to them. Additionally by providing this recess
bottom shape, a protruding upper shape permits the unit's upper shape or line 16
to permit the carriers to be readily stacked with interlocking capability.
In the past, aluminum trays have been used to carry such modules because
they are conductive; however, it was found that such aluminum trays were costly
to purchase and maintain and many times failed to provide adequate grounding
of the semiconductors because the module was supported by the cap which in
turn was insulated from the device by an epoxy backseal. The present carrier of
conductive plastic allows the module to be supported by the main body of pins
that provide a ground to the device. In addition, the proposed carriers are
approximately 1/8 the cost of the aluminum trays and consume approximately 1/3
less space than the aluminum trays while maintaining a 10 to 1 weight reduction
and preventing damage to the modules being carried therein.
