US Patent 7607762 - CNT anti-wetting nozzle plate

http://www.freepatentsonline.com/7607762.html

In inkjet printers it is important for the surface of the printhead to be resistant to wetting in order to avoid misdirected ink drops from printing nozzles. This patent from Fujifilm teaches a carbon nanotube layer which provides such anti-wetting in addition to good durability. Claim 1 reads:

1. A nozzle plate comprising:

a nozzle through which liquid is ejected;

a nozzle forming surface in which the nozzle is provided; and

a liquid-repellency layer which is provided on the nozzle forming surface, the liquid-repellency layer including a carbon nanotube layer.

US Patent 7367999 - Method of producing nanoparticle film using sputtering

http://www.freepatentsonline.com/7367999.html

This patent from Fujifilm teaches a method of producing nanoparticles of a larger variety of compositions and which is less subject to agglomeration. Claim 1 reads:

1. A method of producing ultrafine particles by vaporization comprising:

vaporizing a target by sputtering;

causing particles that fly from the target by vaporization to be deposited on an oil surface; and

recovering the oil on which the flown particles have been deposited to obtain individually dispersed ultrafine particles, wherein the target is a multi-element compound.
