| 20080266755 | NbO Capacitors With Improved Performance and Higher Working Voltages - A capacitor is described with an NbO anode. The capacitor has an NbO anode and an NbO anode lead extending from the NbO anode. A dielectric is on the NbO anode and a conductor is on the dielectric. | 10-30-2008 |
| 20090251847 | CAPACITOR WITH SACRIFICIAL LEAD WIRE CONFIGURATION AND IMPROVED MANUFACTURING METHOD THEREOF - The capacitor has a monolithic anode and at least one anode lead wire extending from the anode. At least one sacrificial lead wire extends from the anode. A dielectric layer is on said anode and a cathode layer is on the dielectric layer. The anode lead wire is in electrical contact with the anode and a cathode lead is in electrical contact with the cathode. | 10-08-2009 |
| 20110149477 | SOLID ELECTROLYTIC CAPACITOR AND METHOD OF MANUFACTURE - An improved solid electrolytic capacitor and method of forming a solid electrolytic capacitor is described. The method includes forming an anode comprising a valve metal or conductive oxide of a valve metal wherein an anode lead extension protrudes from the anode. A dielectric is formed on the anode and a cathode layer is formed on the dielectric. The anode, dielectric, and cathode layer are encased in a non-conducting material and the anode lead extension is exposed outside of the encasement at a side surface. A conductive metal layer is adhered to the anode lead extension which allows termination preferably by electrically connecting a preformed solid metal terminal, most preferably an L shaped terminal, to the conductive metal layer at the side surface. | 06-23-2011 |

| 20080247121 | HIGH VOLTAGE SOLID ELECTROLYTIC CAPACITORS USING CONDUCTIVE POLYMER SLURRIES - A method for forming a capacitor including forming an anode from a valve metal; forming an oxide on the anode to form an anodized anode; dipping the anodized anode into a slurry of conductive polymer; drying the intrinsically conductive polymer; and providing external terminations in electrical contact with the anode and the conductive polymer. | 10-09-2008 |
| 20080250620 | Process for manufacturing low ESR conductive polymer based solid electrolytic capacitors - A method for maintaining quality of monomer during a coating process for intrinsically conductive polymer which suppresses unwanted by-products. A neutralization process using a base or anion exchange resin is used batch-wise or continuous. | 10-16-2008 |
| 20080283409 | Use of conjugated oligomer as additive for forming conductive polymers - A process for forming a capacitor. The process includes providing an anode; providing a dielectric on the anode; exposing the anode to a polymer precursor solution comprising monomer, conjugated oligomer and optionally solvent and polymerizing the polymer precursor. The ratio between monomer and conjugated oligomer ranges from 99.9/0.1 to 75/25 by weight. The solvent content in the polymer precursor solution is from 0 to 99% by weight. | 11-20-2008 |
| 20080299371 | Anodes with corner and edge modified designs - Porous sintered anode bodies for capacitors formed from valve metals are treated by electrolysis to form a dielectric layer and coated with cathode layers. When standard parallelpiped shapes are used, cathode coverage at the edges and corners is non-uniform and failures occur at those locations. Rectangular prisms, obround prisms and cylindrical prisms are formed with transition surfaces at edges and corners, such as chamfers and curves, to enhance cathode layer uniformity. The transition surface greatly enhances the application of polymer slurries. | 12-04-2008 |

| 20090044400 | CABLE MARKER PLACEMENT TOOL AND METHOD - An apparatus for lifting and applying a rolled, tubular aerial cable marker to a cable, including a support, a top holding bar carried by the support for receiving and retaining a top end of a cable marker roll in an at least partially unrolled, tensioned condition, and for positioning and releasing the top end of the cable marker onto the cable. A bottom holding bar is carried by the support and retains a bottom end of the rolled cable marker, and releases the bottom end of the cable marker onto the cable, thereby allowing the cable marker to return to its initial, rolled tubular shape in position around the cable. A related method is also disclosed. | 02-19-2009 |
