タイトル: 強凝集微粒子の分散技術と量子触媒合成装置の開発 著者: 長嶋, 順一; 市来, 克己; 岸, 政七 抄録: The Quantum catalyst has been discussed to put on development stage with emphasizing both on dispersion technologies for strong particle aggregation and catalyst synthetic reactors. It is successfully examined that the Quantum catalyst is synthesized by adapting newly proposing synthetic reactor to achieve more than five times photo catalyst reaction velocity that of the most effective existing photo catalyst in ultraviolet irradiation. This synthetic reactor is simultaneously facilitated both with supercritical fluid and such comparatively large size bead mill as mild dispersion.

タイトル: SPMを用いたSi単結晶のナノ加工と表面の構造変化 著者: 高木, 誠; 松室, 昭仁; 岩田, 博之 抄録: The fabricating methods of nanoscale shapes on Si (100) surface by using atomic force microscope (AFM) and scanning tunneling microscope (STM) were investigated. As a result, nanoscale grooves and faces were fabricated by the scratching methods using AFM. The scratching loads had a major influence on these shapes. Nanoscale pits, grooves and faces were fabricated by STM as a result of controlling the sample bias voltage and the tip curvature radius of tungsten probes. Cross-sectional TEM observations of the nanoscale grooves and faces fabricated by AFM and STM were carried out to study the microstructural changes of Si single crystals. As a result of the TEM observations, it was found that many dislocations and an amorphous appeared in the surface of the grooves and faces fabricated by AFM. On the other hand, the single crystalline structure without a dislocation was preserved in the surface of the grooves and faces fabricated by STM. Based on these results, itis considered that the fabricating mechanisms of AFM and STM are a mechanical processing and an electric field evaporation, respectively.

タイトル: スクイーズ膜効果を用いたミニチュアロボット浮上量推定とその応用 著者: 山田, 智弘; 鳥井, 昭宏; 植田, 明照 抄録: This paper describes a feasibility of floating height estimation of a miniature robot using squeeze film effect. The miniature robot can levitate with a vertically vibrating piezoelectric element. It is difficult to measure the floating height of the robot because of the restriction of measurement instruments. The input voltage and load current of the piezoelectric element used in the vertical vibration contain the information of the floating height. The input voltage and load current which are obtained in both the floating miniature robot and the landing miniature robot are compared. An inchworm-type miniature robot using a vertical levitation is also proposed. The levitating elements move sequentially by the deformation of a horizontal piezoelectric element. Some experimental results are shown.

タイトル: Influence of Microwave Irradiation on　Water-vapor Desorption Capacity of Zeolites 抄録: Typical adsortive desiccant cooling process mainly consisting of a rotary dehumidifier (D-hum) and heat exchanger can be driven with low-temperature heat energylike solar energy or waste heat. However, the desorption rate decreases and the energy consumption increases in desorption process of D-hum was found. For the efficient development of D-hum, a microwave heating type D-hum was proposed. The microwaves have the characteristics energy is readily transformed into heat inside the particles by dipole rotation and ionic conduction and selectively heats water in the adsorbent. Consequently, processes based on microwave is now considered a promising rapid desorption technology compared to conventional heating. In this study, the effect of heat and microwave irradiation on adsorbed water-vapor desorption from various type zeolites was studied. Desorption performance of water from zeolites by microwave heating under the conditions of N2 gas of 30℃ with relative humidity 40%, microwave power of 800W was compared with that for hot-air heating at 40～80℃ and microwave power of 50W. The effect of microwave irradiation was approved to be better than that of hot air heating in any zeolites.
