[Research Duration : 1997/APR.`2001/MAR.]
[Outline of Research : Silicon is widely used as substrate for solar cell. To reduce the producing cost, solar grade (SOG) silicon, which means the low purity silicon compared to semiconductor grade (SEG) silicon, must be used as feed material with high productivity rate. Therefore, it must be needed to increase the crystal growth rate. In the case of low purity silicon feed, however, impurities in the crystal are usually increased by increasing the growth rate. The efficiency of solar cell will be decreased when the low grade silicon crystals are used as substrates. To avoid this phenomenon, melt flow control seems one of the good methods due to the dynamic segregation coefficient. If the melt flow velocity is decreased near the crystal growth front, the incorporated impurity concentration in the crystal is decreased. To control the melt flow field and obtain a high purity silicon crystal, effect of externally applied magnetic field on the melt convection during the floating zone (FZ) crystal growth process is experimentally and analytically investigating.][No.1331]

[Outline of Research : Open MRI-guided surgical treatment, or MR/T (MR Treatment), is a promising approach toward the minimum invasive surgery (MIS) and just-in-time diagnosis during the surgery. It leads to the better Quality-of-life (QOL) and the lower medicare costs. However, open MRIs are not roomy. Their imaging ability is not equivalent to high-tesla MRIs. Functional MRI (fMRI) is not practical. To enhance open-MRI guided surgery, we study a combination of MRI-compatible surgical manipulator(s) and near-infrared optical measurement system. The manipulator assists accessing to the legions, and optical system visualizes distribution of oxi/deoxidization of blood flow. We also study fast imaging sequence and intraoperative registration. The goal of this study is to demonstrate a concurrent system of diagnosis and treatment and its clinical evaluation. It is a joint project of MEL, The University of Tokyo, The Osaka University, and Tokyo Womens Medical Collage.]
