  • The possibility of an active-matrix carbon nanotube field emission display (AM-CNT FED) is discussed from the view points of display performance and cost. The critical issues for FED commercialization such as anode acceleration voltage, uniformity, stability and reliability can be solved through our AM-CNT FED technologies.

  • In this paper, the possibility of time reversal phenomenon was investigated in damage detection of structure. In conventional lamb wave techniques, damage is identified by comparing the measured data (baseline signals) and the current data. But this method can lead to high false signal in the intact condition of structures due to environmental conditions of the structures. So in this studying, we investigate the possibility of damage detection in the aluminum plate using the time reversal phenomenon of lamb waves.

  • This study area has been contaminated by oils. To identify contaminated ranges and to assess the possibility of contamination dispersion, monitoring wells were installed and slug test, field soil permeability test, automatic or manual measurement of groundwater table, and groundwater quality analyses in field and laboratory were performed. In addition, a groundwater modeling program was used to assess the possibility of oil contamination dispersion, based on field data and groundwater quality data. The results showed that concentration of oil contaminants in groundwater have been decreased by dispersion and adsorption.

  • Si TFTs are applied not only to stacked SRAM but also to FPD. Improvement of device characteristic such as an enhancement of carrier mobility or a reduction of leakage current is studied intensively. The TFT technology is developing based on conventional Si LSI technology. By establishing a stable fabrication process on flexible substrate and high performance characteristic uniformly and reliably, TFT technology has a possibility to develop to SOP or other highly functional applications similar to or beyond the conventional Si LSI in the era of information and telecommunication.

  • The main objectives in the first year include selection of the MEMS bonding methods and feasibility study of selected methods. The ultrasonic bonding method is chosen for MEMS packaging, and the processes to provide localized heating are proposed. The ultrasonic bonding process is analyzed using a lumped model. Preliminary experiments using the eutectic solder and copper pin were performed to verify possibility to MEMS packaging. The preliminary results show possibility of the ultrasonic bonding method for MEMS packaging.

  • This study presents the applicable possibility of numerical optimization and Genetic Algorithm in the design of truss structures using discrete variables and real constraints. The introduction of Genetic Algorithm in the design of truss structures enables us to do easier formulation and handle discrete variables. To investigate these applicable possibility, the design of 15 - bar truss structures has been studied using GT/STRUDL and Genetic Algorithm and the results of Genetic Algorithm are compared with GT/STRUDL's.
