Publication number: 20140349547Abstract: A system may include two character figurines, each of which may be an action figure. Each character figurine may have a body with a humanoid shape. The character figurines may include a first character figurine with a wireless transmitter that transmits a wireless signal, and a second character figurine with a wireless receiver that receives the wireless signal. The second character figurine may have an action system that causes the second character figurine to undertake a visually perceptible action when the wireless signal is received. The action system may include a motor, and the visually perceptible action may include motion of the second character figurine, driven by the motor, that approximates receipt of a wound inflicted by the first character figurine.Type: ApplicationFiled: December 4, 2013Publication date: November 27, 2014Inventors: James A.

Patent number: 7156893Abstract: Methods of forming niobium powders and other metal powders are described. The method involves milling the metal powders at elevated temperatures and in the presence of at least one liquid solvent. The methods of the present invention have the ability to reduce DC leakage and/or increase capacitance capabilities of metal powders when formed into capacitor anodes. The present invention further has the ability to significantly reduce the milling time necessary to form high surface area metal powders and leads to reducing the amount of contaminants in the metal powders. Metal powders such as niobium powders having reduced amount of contaminants and/or having DC leakage or capacitance capabilities are also described. A process is further described for forming a flaked metal by wet-milling a metal powder into a flaked metal wherein at least one liquid fluorinated fluid is present during the wet-milling process.Type: GrantFiled: February 3, 2004Date of Patent: January 2, 2007Assignee: Cabot CorporationInventors: Kurt A.

Patent number: 6864147Abstract: A solid electrolytic capacitor that comprises an anode that contains a valve-action metal (e.g., tantalum, niobium, and the like) and a dielectric film overlying the anode is provided. The capacitor also comprises a protective coating overlying the dielectric film, wherein the protective coating contains a relatively insulative, resinous material. For example, in one embodiment, the resinous material can be a drying oil, such as olive oil, linseed oil, tung oil, castor oil, soybean oil, shellac, and derivatives thereof. The capacitor also comprises a conductive polymer coating overlying the protective coating. As a result of the present invention, it has been discovered that a capacitor can be formed that can have a relatively low leakage current, dissipation factor, and equivalents series resistance.Type: GrantFiled: August 22, 2003Date of Patent: March 8, 2005Assignee: AVX CorporationInventors: James A.
