The circuit breaker has a power transmission mechanism for driving a movable contact 63 and a fixed contact 64 and an interruption spring 26 that imparts a driving force... http://www.freshpatents.com/Switch-device-dt20090813ptan20090201110.php Tue, 18 Aug 2009 22:20:10 -0700 A movable contact positioned in a sealed case is moved together with a movable contact spring provided with an armature by a magnetic shunt body which is moved outside the sealed case. The movement of the movable contact (movement of the movable contact spring) due to the movement of the... http://www.freshpatents.com/Generating-electromagnetic-forces-with-flux-feedback-control-dt20090813ptan20090201111.php Tue, 18 Aug 2009 22:20:10 -0700 An electromagnetic actuator with flux feedback control includes two poles located on opposite sides of a soft-magnetic target. A bias flux is introduced that flows into both poles. Magnetic circuitry may be designed so that the total bias flux is independent or substantially independent of a position of the target... http://www.freshpatents.com/Method-of-encasing-a-magnet-and-an-encased-magnet-dt20090813ptan20090201112.php Tue, 18 Aug 2009 22:20:10 -0700 A method of encasing a magnet to isolate the magnet from the environment is provided. The method includes introducing a magnet to a housing having at least one passage capable of passing a fluid from the environment to the magnet, introducing a hardenable fluid, for example, a resin, to the...
