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.
This article describes a novel method of attaching pins to a substrate and a
novel fixture for use in such attachment of the pins.
The fixture includes a base member 10 and a cover member 12 which are
releasably attached by locking pins, one of which is shown at 14. The base
member includes walls 16 which are shaped to slidingly engage the substrate 18
to which the pins are to be attached. The walls 16 also slidably engage a pin
carrier 20 in which are slidably mounted the pins 22.
The cover member is provided with an elastomeric gas-tight membrane 24
which together with the end 26 of the cover forms a gas-tight compartment 28. A
conduit 30 communicates with the compartment 28, the conduit being connected
to a source 32 which can apply either vacuum or pressure.
To attach pins, a slight vacuum is first pulled and maintained by source 32
when the members 10 and 12 are secured together. Thereafter, the carrier 20,
with the pins 22 mounted therein, is inserted into the base 10, and the pins are
pushed snugly against the membrane 24. The substrate is then inserted into the
base 10 such that the pins 22 contact the surface metallization 34 of the
substrate. A ram, which is shown schematically at 36, applies a force to insert
both the pin carrier and the substrate.
When the substrate and pin carrier are in place, the vacuum is released and
a positive pressure is applied in space 28 from source 32. This w...
