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.

Functional Dew Point Measurement In A Sintering Furnace
Close control of the dew point and the flow rate of the atmosphere around
ceramic substrates during sintering is important because variations in the flow
and dew point influence critical parameters.
It has been found that the shrinkage of the molybdenum paste system is
much more sensitive to the dew point and/or the flow rate than ceramic material.
By placing a molybdenum sample at each level in the sintering furnace and
measuring the shrinkage after sintering, a constant check can be kept on the
atmosphere characteristics of a particular furnace. The procedure may help to
explain variations in the MLC (multilayer ceramic) product when and if they
