Method and apparatus for forming image
A method and apparatus for forming an image which can form a high-quality image on a great variety of print media regardless of the surface roughness or ink absorptivity of the print medium, without sacrificing the high degree of freedom of the ink jet printing system are provided. An ink jet printing section ejects ink to an intermediate transfer body to form an ink image on the intermediate transfer body. Before the ink image thus obtained is transferred to a print medium, an ink transfer adjuvant is applied to the print medium. Then, the ink image formed on the intermediate transfer body is transferred to the print medium to which the ink transfer adjuvant has been applied.

Bonding thermoplastic polymers
InactiveUS7390377B1UniformUniform surface propertiesMechanical working/deformationAdhesive processes with surface pretreatmentMicrometerThermosetting polymer
We demonstrate a new method for joining patterned thermoplastic parts into layered structures. The method takes advantage of case-II permeant diffusion to generate dimensionally controlled, activated bonding layers at the surfaces being joined. It is capable of producing bonds characterized by cohesive failure while preserving the fidelity of patterned features in the bonding surfaces. This approach is uniquely suited to production of microfluidic multilayer structures, as it allows the bond-forming interface between plastic parts to be precisely manipulated at micrometer length scales. The bond enhancing procedure is easily integrated in standard process flows and requires no specialized equipment.
