The influence of pore size distribution of the phenol-based adsorbents (RP-15 and RP-20) on adsorption and desorption of methane were investigated. The isotherm data were measured using a static volumetric method at three different temperature (293.15,303.15 and 313.15) K and at pressure up to 35 atm. These experimental data were well-correlated by the Sips and Toth isotherm models. The surface energetic characteristics of the adsorbents were evaluated by Clausius-Clapeyron equation.

The mechanical rotation system is made up of belts, mass disks and gears. This precise piece of equipment is controlled electro-mechanically by the motor and operation program. The control strategy of the system can be changed by belts` stiffness and change of the mass and gear. That is called the parameter. This system can be modeled as a rigid body, and also finds broad application in such diverse fields in machine tools, the cruise control system in automobiles, and control attitude. This system proves the necessity and effect of a closed loop control. The study of the mechanical rotation system excited by its base motion is not only able to predict the rotational performance, but also obtain the fundamental data for vibration isolation. study, thesis, we determined many parameters and measured the hardware gain such as the belts` stiffness, the inertia moment of motor, the inertia of pulley ect. These facts are very important to understand the characteristics of rotating system.

The development of the surface micromachining process for micro gyroscope fabrication is presented in this paper. The 5.3㎛ thickness of doped polysilicon actuator structures have been fabricated successfully with using multi step polysilicon deposition and POCl₃ doping process, and also by using HF gas-phase etching process for 1.5 ㎛ thickness of sacrificial oxide. After annealing and sacrificial oxide removal, the final compressive stress and stress gradient in the doped polysilicon is measured as 46 MPa and -0.5 MPa/㎛, respectively.

We obtained fluorinated silicon oxide (SiOF) films having a low dielectric constant, 3.02, by using NF₃ as a F-source gas. By FTIR (Fourier Transform Infrared) studies, the local atomic structure of the films was changed by fluorine incorporation, a it was suggested that the molar volume of those be increased by the incorporation. The increase of the molar volume is proposed to be a factor which decreases the dielectric constant from the Lorentz-Lorenz equation.
