A new laser-addressing method is proposed in this paper. With the characteristic of high power and small spot size, simple structure electronic paper can be addressed only by laser source, and high quality image with 300dpi resolution can be easily achieved.

Carbon nanotube arrays were fabricated using micro molding in capillary (MIMIC) process. Patterns remained on the surface in the pattern complementary to that present in the mold. CNTs were selectively grown on the MIMIC patterned sites with a triode PECVD. And turn on field for $10\;{\mu}A/cm^2$ electron emission current was $2.2\;V/{\mu}m$ turn on field.

We report the light illumination effect on the performance of pentacene organic thin-film transistor (OTFT). The TFT performance with and without illumination were measured at various temperatures. The off-state currents increase linearly with light intensity in the region of gate voltage where the holes are majority carriers in the TFT channel. The minimum photocurrents of OTFT increase with increasing light intensity.

We have proposed a novel cleaning technology with organic nanoparticles for high-performance TFT array. The surface of the TFT layer becomes more hydrophilic after cleaning by the nanoparticles. This is concluded from the comparison of contact angles for the samples cleaned by various methods. It is found that the drain currents in the subthreshold and off-state regions are less than those for the TFTs cleaned with conventional method.

WERC (Wakasa Wan Energy Research Center) has started the proton cancer therapy since June 2002. We use Hitachi 3D treatment planning (version 1.6) that can calculate the proton dose distribution by use of the pencil beam algorithm as well as the broad beam algorithm practically fast. This treatment planning software satisfies almost functions required in the proton therapy and includes some advanced techniques such as the 3D region glowing function that can search the target region three-dimensionally based on the CT-values. In this paper, we will introduce this planning system and present our evaluation from point of view of both clinical usage and QA.
