20090090200 | GYROSCOPE - A gyroscope ( | 04-09-2009 |
20090320167 | MECHANICAL VIBRATOR AND PRODUCTION METHOD THEREFOR - A mechanical oscillator which defines a starting point of a cantilever at a front edge of a base and can determine the length of the cantilever without depending on an alignment accuracy and an etching amount, and a fabrication method of the mechanical oscillator. The mechanical oscillator, produced by processing a wafer, comprises a base ( | 12-24-2009 |
20100045137 | ACTUATOR AND METHOD FOR MANUFACTURING THE SAME - An actuator that can be driven at a reduced voltage and manufactured with ease, and a method for manufacturing the same are provided. The actuator includes second supporting portions 31 and 32 secured to a supporting substrate 4 through a spacer, fixed portions 33 and 34 secured to the supporting substrate 4 with no intervention of the spacer, fixed comb electrodes 331 and 341 integrally formed the fixed portions 33 and 34 and meshing with movable comb electrodes 211 and 212 in a spaced-apart relationship, and bridge portions 35 and 36 for connecting the fixed portions 33 and 34 to the second supporting portions 31 and 32. The fixed portions 33 and 34 are affixed to the supporting substrate 4 in a condition that they are deflected toward the supporting substrate 4 with respect to the second supporting portions 31 and 32 while bending the bridge portions 35 and 36, thereby initially deflecting the fixed comb electrodes 331 and 341 so as to be out of alignment with the movable comb electrodes 211 and 212 in a thickness direction of the supporting substrate 4. | 02-25-2010 |

20090256823 | Display Device and Transparent Magnetic Film - A display device is provided with an optical waveguide, a transparent fixed electrode disposed in surface contact with the optical waveguide, and a transparent movable electrode disposed facing the transparent fixed electrode on a side opposite to the optical waveguide. When a driving voltage is applied, the transparent movable electrode is movable by an external force, between a first stable state in which it is kept apart from the transparent fixed electrode by elasticity, and a second stable state in which it makes insulated contact with the transparent fixed electrode by electrostatic force. | 10-15-2009 |
