Patent number: 6413282Abstract: The invention has an object to reduce the impedance and to improve the responsiveness at high frequencies in an electrolytic capacitor having an conducting polymer layer as the cathode. A cathode current collector is directly joined with the surface of the dielectric of a valvular metal porous body for anode using an conducting polymer layer but not through various binding layers (for example, a carbon layer and a silver layer) thereby reducing the impedance. A cathode current collector is disposed adjacent and opposite to a porous valvular metal foil for anode. This structure ensures that the collecting area is enlarged. In this case, a cathode current collector may be directly joined with the surface of the dielectric of a valvular metal porous body for anode using an conducting polymer layer but not through various binding layers thereby reducing the total impedance.Type: GrantFiled: November 15, 1999Date of Patent: July 2, 2002Assignee: Matsushita Electric Industrial Co., Ltd.Inventors: Masakazu Tanahashi, Emiko Igaki

Patent number: 6415257Abstract: Speech input supplied by the user is evaluated by the speaker verification/identification module, and based on the evaluation, parameters are retrieved from a user profile database. These parameters adapt the speech models of the speech recognizer and also supply the natural language parser with customized dialog grammars. The user's speech is then interpreted by the speech recognizer and natural language parser to determine the meaning of the user's spoken input in order to control the television tuner. The parser works in conjunction with a command module that mediates the dialog with the user, providing on-screen prompts or synthesized speech queries to elicit further input from the user when needed. The system integrates with an electronic program guide, so that the natural language parser is made aware of what programs are available when conducting the synthetic dialog with the user.Type: GrantFiled: August 26, 1999Date of Patent: July 2, 2002Assignee: Matsushita Electric Industrial Co., Ltd.Inventors: Jean-Claude Junqua, Roland Kuhn, Tony Davis, Yi Zhao, Weiying Li
