20060208843 - Method and apparatus for decreasing gassing and decay of insulating oil in transformers: The invention deals with increasing the quality of insulating mineral oil in transformers, by providing an isolating layer of flowing nitrogen over the oil's surface to keep ambient air from combining or absorbing with or in the oil, also providing a kidney or filter to remove undesirable contaminants such as...

20060208844 - Iron core, iron core manufacturing method, alignment apparatus, and exposure apparatus: An iron core includes an electromagnetic steel plate having a first region on the surface of which an insulating film is formed and a second region which is not covered with the insulating film and exposed, and a coating member which coats at least the second region. The second region...

20060202789 - Electrically decoupled integrated transformer having at least one grounded electric shield: An integrated circuit, such as a radio frequency integrated circuit (RFIC), has a first layer bearing first metallization patterned for defining a first inductive coil, a second layer bearing second metallization patterned for defining a second inductive coil that overlies the first inductive coil and that is magnetically coupled to...

20060202790 - Toroidal inductive devices and methods of making the same: An inductive device comprises an electric winding component having a generally toroidal shape, and a plurality of discrete magnetic components at least partially embracing the electric winding component so as to complete a magnetic flux path and to form at least one gap between end portions of the plurality of...

20060197642 - Variable inductor technique: An integrated variable inductor is achieved by placing a second closed-loop inductor immediately above or below a primary inductor. The closed-loop configuration of the second inductor may be broken on-chip by several ways, including use of a transistor to selectively short together both ends of the second inductor. If one...

20060197643 - Bobbin module of transformer: A bobbin module of transformer is provided. The bobbin module includes two bobbins. Each of the bobbins comprises a body, an indentation and a hooker. The body has a lateral surface on which the indentation and the hooker are disposed. The hooker and the indentation of the bobbin are respectively...

20060197644 - Flat inductor and the method for forming the same: An inductor comprises a coil portion having two connecting leads; the two leads being bent inwards; a layer of insulating material coated upon surfaces of the coil portion and the two leads as an insulating layer; an layer of insulating enclosure enclosing the coil portion and the leads, end surfaces...
