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.

Silicon Arms for DASD
A suspension for a magnetic transducer for use in a disk storage device is
described in with the suspension is made from silicon.
The suspension includes an accessing arm having at least the slider gimbals
made of silicon. The silicon has an etched- through groove in a pattern to
provide a first torsion plate 1. Torsion plate 1 is etched all around its periphery
except for two torsion bars 2 which attach plate 1 to the accessing arm. Within
torsion plate 1 a second torsion plate 3 is produced by an etched-through groove
in the silicon in a pattern all around the periphery except for two torsion bars 4
which attach torsion plate 3 to torsion plate 1. The axis of rotation of torsion bars
4 so that attached slider 5 can follow the contour of the associated disk to
maintain the selected flying height for the magnetic transducer on slider 5.
