| 20100079849 | DEVICE AND METHOD FOR MODIFYING ACTUATION VOLTAGE THRESHOLDS OF A DEFORMABLE MEMBRANE IN AN INTERFEROMETRIC MODULATOR - By varying the spacing between a partially-reflective, partially-transmissive surface and a highly reflective surface positioned behind the partially-reflective, partially-transmissive surface, an interferometric modulator selectively creates constructive and/or destructive interference between light waves reflecting off the two surfaces. The spacing can be varied by applying a voltage to create electrostatic attraction between the two surfaces, which causes one or both surfaces to deform and move closer together. In the absence of such attraction, the surfaces are in a relaxed position, where they are farther apart from one another. A actuation voltage is needed to create sufficient electrostatic attraction to cause a surface to deform. The actuation voltage can be modified by implanting ions in a dielectric layer attached to one or both surfaces. Upon the application of a voltage, the ions create a baseline level of repulsion or attraction between the two surfaces, which thus require more or less voltage, respectively, to cause a surface to deform. The degree of ion implantation can be chosen to set the actuation voltage as desired, or the surfaces can be made to deform at a given voltage by appropriately selecting the degree of ion implantation. | 2010-04-01 |

| 20100079927 | CAPACITOR AND METHOD OF MANUFACTURING THE SAME - A capacitor includes a capacitor element including first and second electrodes, an electrolyte solution, first and second collector plates made of metal and joined to the first and second electrodes of the capacitor element, respectively, a case accommodating the capacitor element, the electrolyte solution, the first and second collector plates, a terminal plate placed at an opening of the case and joined to the second collector plate, and a sealing rubber sealing the terminal plate and the opening of the case. The case has a tubular portion and a bottom plate closing the tubular portion. An inner surface of the bottom plate of the case has a contacting portion contacting the first collector plate and a junction portion facing the first collector plate. The first junction portion of the inner surface of the bottom plate has a joining point joined to the first collector plate and a separation part facing the first collector plate around the first joining point by a first gap between the first junction portion and the first collector plate. The first collector plate is located away from the first contacting portion. The capacitor has a high reliability in connecting the electrodes, preventing an unnecessary resistance or a pin hole produced in the case. | 2010-04-01 |
| 20100079928 | SOLID ELECTROLYTIC CAPACITOR AND FABRICATION METHOD THEREOF - A solid electrolytic capacitor comprising an anode composed of a valve metal or its alloy, a dielectric layer formed on a surface of the anode, a coupling agent layer formed by subjecting the dielectric layer to a surface treatment with a coupling agent having a phosphonic acid group, a conductive polymer layer formed on the coupling agent layer, and a cathode layer formed on the conductive polymer layer. | 2010-04-01 |
