چکیده

We proposed a CB (concentric build-up) process to fabricate the electrostatic wobble motors in MEMS '94[ 11. This process features the concentric build-up of layers around a cylindrical substrate and produces three dimensional bulk structures using newly developed microfabrication technique. This time, we have successfully measured the wobbling motion and estimated key motor parameters such as rotation rate, rotor-stator gap, output torque and surface condition of stator and rotor. This method facilitated the evaluation of the motors and processes. And we have located the causes of torque deterioration.

CHARACTERIZATION OF MICRO/NANO POROUS HOLLOW GLASS MICROSPHERES FABRICATED THROUGH VARIOUS CHEMICAL ETCHING PROCESSE FOR USE IN SMART COATINGS

Porous hollow glass microspheres have many uses, including encapsulation of active materials. In this paper a fast and facile method for fabricating porous hollow glass-microspheres was demonstrated by etching them using dilute hydrofluoric acid. Then, a highly reactive amine was infiltrated into the etched glass microspheres. Scanning electron microscopy was conducted for the hollow glass micr...

Optimization of an HTS Induction/Synchronous Motor According to Changing of HTS Tapes Critical Current by Analytical Hierarchy Process

This paper represents the performance of a squirrel-cage High Temperature Superconducting Induction/ Synchronous Motor (HTS-ISM) based on nonlinear electrical equivalent circuit. The structure of the HTS-ISM is the same as that of the squirrel-cage type induction machine, and the secondary windings are fabricated by the use of the HTS wires. It has already been shown that based on the experimen...

Interpretation of In-air Output Ratio of Wedged Fields in Different Measurement Conditions

Introduction: The head scatter factor (Sc) is one of the important parameters for monitor unit (MU) calculation. There are multiple factors that impact the Sc values, such as, head structures, back scattering in to dose monitoring chambers, wedges and so on. This study aimed to investigate the variations of SC with different build-up cap materials, wall thickness, Source to ...
