Patent number: 8293957Abstract: Described are oligotetracenes of formula I which may either be unsubstituted or carry one or more substituents R and R? which are selected from the group comprising halogen, CN, alkyl or alkoxy radicals containing 1 to 18 carbon atoms, aryl radicals containing up to 10 carbon atoms which may also contain one or more heteroatoms, and/or fluorinated or perfluorinated alkyl or alkoxy radicals containing 1 to 18 carbon atoms, where n is an integer from 1 to 20, preferably 1 to 6, very particularly preferably 1 or 2, and X stands for a single bond, an alklyene group containing 1 to 6 carbon atoms, a hydrocarbon chain having one or more conjugated double bonds, an aryl group, or a system composed of one or more condensed aromatic rings. In the oligotetracenes according to the invention, one or more of the condensed aromatic six-atom rings may be substituted by a five-atom ring which may also contain a heteroatom.Type: GrantFiled: June 21, 2006Date of Patent: October 23, 2012Assignee: Dritte Patentportfolio Beteiligungsgesellschaft mbH & Co.

Patent number: 4612145Abstract: A new method for fabricating electret-containing devices is disclosed. The inventive method includes a new technique for fabricating electrets, which involves applying a voltage across an electrically polarizable body. Large-scale breakdown effects in the body are avoided by reducing the voltage across at least a portion of the body undergoing polarization in response to a current indicating the onset of a breakdown in the body.Type: GrantFiled: March 26, 1984Date of Patent: September 16, 1986Assignee: AT&T Bell LaboratoriesInventors: Harvey D. Keith, Heinz von Seggern, Tsuey T. Wang, James E. West

Patent number: 4527218Abstract: A method of producing charged Teflon material having a stable internal positive charge is shown. Partially penetrating positive ions, which may be produced, for example, by a corona discharge or ion beam, are applied to Teflon at an elevated temperature, typically in excess of 100 degrees Celsius for high stability. It has been found that stable internal positive charges may be obtained thereby, having a stability at room temperature in excess of 2,000 years in some cases. This is comparable to the charge stability of negatively internally charged Teflon articles. Regions of both positive and negative internal charges may be included in the same article. Various charged Teflon devices may be made, including microphones, loudspeakers, electrostatic air filters, etc. Intermediate levels of charge stability, less than the maximum obtainable, may also be produced.Type: GrantFiled: June 8, 1981Date of Patent: July 2, 1985Assignee: AT&T Bell LaboratoriesInventor: Heinz von Seggern

Patent number: 4512941Abstract: Electrically polarizable material (e.g., PVDF film) is poled by applying an electric field across the film. In the inventive technique, insulation is provided on the surface of the film. In a typical embodiment, a compliant dielectric annulus insulates the polarized region from the edges of the film. This substantially eliminates breakdown at the edges of the film, allowing increased poling voltages. The technique can reduce poling time to typically a few seconds at room temperature, as compared to minutes or hours by prior art techniques, some of which required elevated temperatures.Type: GrantFiled: February 14, 1983Date of Patent: April 23, 1985Assignee: AT&T Bell LaboratoriesInventors: Heinz von Seggern, Tsuey T.
