  • Patent number: 11908884
    Abstract: An inductive device includes an insulating layer, a lower magnetic layer, and an upper magnetic layer that are formed such that the insulating layer does not separate the lower magnetic layer and the upper magnetic layer at the outer edges or wings of the inductive device. The lower magnetic layer and the upper magnetic layer form a continuous magnetic layer around the insulating layer and the conductors of the inductive device. Magnetic leakage paths are provided by forming openings through the upper magnetic layer. The openings may be formed through the upper magnetic layer by semiconductor processes that have relatively higher precision and accuracy compared to semiconductor processes for forming the insulating layer such as spin coating. This reduces magnetic leakage path variation within the inductive device and from inductive device to inductive device.

  • Patent number: 10288146
    Abstract: A dual eccentric shaft driving mechanism comprises a motor, a first eccentric shaft, and a second eccentric shaft. The first eccentric shaft has a first eccentric portion. The second eccentric shaft has a second eccentric portion connected to the first eccentric shaft. The motor is connected to the first eccentric shaft for driving the first and the second eccentric shaft to rotate. Wherein, the first and the second eccentric shaft are connected to have a same rotating direction. A phase difference between the first and the second eccentric portion is maintained at 180 degrees. Compared to the prior art, a second centrifugal force generated by the rotation of the second eccentric shaft is balanced by a first centrifugal force generated by the rotation of the first eccentric shaft in the present invention. Therefore, the vibration generated in the operation of the present invention is drastically reduced.
