Patent number: 7489211Abstract: An electromechanical filter capable of achieving overall miniaturization by employing a micro oscillator such as a carbon nanotube with superior conductivity so as to enable selection of signals of a predetermined frequency. The apparatus includes an inner wall composed of a carbon nanotube that changes physically as a result of an input signal, and an outer wall composed of a carbon nanotube arranged so as to cover the inner wall and spaced by a microscopic gap from the inner wall. The outer wall detects an oscillation of the inner wall when a signal of a predetermined frequency is inputted from a connected signal input side electrode to the inner wall, so that this signal is outputted via a connected signal output side electrode.Type: GrantFiled: August 11, 2004Date of Patent: February 10, 2009Assignee: Panosonic CorporationInventors: Yasuyuki Naito, Yoshito Nakanishi

Patent number: 7209019Abstract: A switch comprises voltage applying means for providing direct current potentials to first to third beams arranged with a spacing slightly distant one from another, and electrodes for inputting/outputting signals to/from the beams. By controlling the direct current potential provided to the beam, an electrostatic force is caused to thereby change the beam positions and change a capacitance between the beams.

Also, an electrostatic force is caused on the third beam arranged facing to the first and second beams, to previously place it close to the first and second beams. When the electrostatic force is released from between the first and second beams, the second beam moves toward the third beam thereby releasing the first and second beams of an electric coupling.Type: GrantFiled: August 11, 2005Date of Patent: April 24, 2007Assignee: Matsushita Electric Industrial Co., Ltd.Inventors: Yoshito Nakanishi, Norisato Shimizu, Kunihiko Nakamura, Yasuyuki Naito
