| Research Abstract |
Studies on optical switches have been researched and developed for optical information networks for a highly developed information technology society. In reality, however, a manipulator cannot apply for multi input and output due to a rather small output displacement at mirror parts inside the manipulator. Therefore, in order to reduce the output errors of micromechanisms, our study has suggested the use of new micro-hinges with a rigidity that has been made suitable enough to decrease the differences between the hinge end locus and the circular locus. Based on this, we have conducted theoretical analyses, while at the same time creating micro-hinge models using a semiconductor minute processing technique for our experiments. Afterwards, we will discuss and study the effectiveness of the use of the suggested microhinges, through comparisons with conventional shaped micro-hinges. The results clarified that the suggested hinge models could reduce errors with the circular locus. This ulti

mately confirms the effectiveness of our newly reinforced micro-hinge. Next, in order to develop optical switches capable of switching multi input and output, we suggested an electrostatic driving-type 2-DOF micro-manipulator that was composed of many beams as well as a micro mirror that is capable of large angular output displacement. After having studied shapes and sizes of micro-manipulators capable of large angular displacement based on theoretical analysis, we also discovered that the suggested micro-manipulator can have a large angular displacement. Moreover, our study suggested the manufacturing process using a minute manufacturing process and then confirmed the adequacy of the suggested electrostatic driving-type micro-manipulator after having manufactured and studied a micro-manipulator model. In the results, we obtained an electrostatic driving-type micro-manipulator that is capable of large angular output displacement by low applied voltage. The manipulator is driven by the method of suction between the beam supporting a mirror and the fixed plate with a insulating membrane on it. From the theoretical analyses, the manipulator output the 32degrees angular displacement with an applied voltage of 95 volts. Less
