US Patent 8018675 - Magnetic head with CNT heat dissipation

http://www.freepatentsonline.com/8018675.html

Electromagnetic coils used in read/write heads of hard disk drives are subject to Joule heating which can produce stress and deterioration over time. This patent from TDK Corporation teaches how carbon nanotubes can be incorporated into the insulation layer of the read/write head to provide heat dissipation. Claim 1 reads:

1. A thin-film magnetic head comprising

a magnetic pole,

a coil surrounding the magnetic pole, and

an insulating layer covering the coil;

wherein the insulating layer is formed from a resin containing a carbon nanotube.

US Patent 7691533 - Electrode with conductive polymer covered CNTs

http://www.freepatentsonline.com/7691533.html

This patent from TDK Corporation teaches a way to increase the energy density of fuel cells for hybrid vehicles by using electrodes including a film of carbon nanotubes covered with conductive polymer. Claim 1 reads:

1. A coated electrode comprising:

an electrode comprising:

a collector with electron conductivity, and

an electrode active material-containing layer with electron conductivity formed on the collector,

wherein the electrode active material-containing layer includes carbon nanotubes, and binder in an amount of 10-80 weight %, and

a separate continuous film of a conductive polymer covering the entire electrode.
