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 method eliminates wire bonding and looping to a head slider surfac when making electrical connections to a magnetic head 1 which is a part of a slider 2, as shown in Fig. 1.

Method for Wiring a Magnetic Head
This method eliminates wire bonding and looping to a head slider surfac
when making electrical connections to a magnetic head 1 which is a part of a
slider 2, as shown in Fig. 1.
With reference to Fig. 2, metal lands 3 are formed on one surface 4 of the
slider for electrical contact with the head electrodes. The lands 3 are formed of
permalloy and copper, which are deposited on the surface 4 with the formation of
the head 1.
The lands 3 extend slightly beyond the surface boundary of the slider, as
illustrated in Fig. 3. These extending ends of the lands are cut to expose the
metal for connection to the wiring pattern 5 on the surface 6. The wiring pattern
5 is formed by deposition through a mask.
Subsequently, the wiring pattern is connected to an electrically conducting
cable 7, supported on a head arm 8, for further connection to read/write circuitry,
as shown in Fig. 2.
