    Abstract: The present invention involves a method and apparatus for canceling the effects of magnetic field noise in a torque sensor by placing three sets of magnetic field sensors around a shaft, the first set of field sensors being placed in the central region of the shaft and the second and third sets of field sensors being placed on the right side and left side of the field sensors placed at the central region, respectively. A torque-induced magnetic field is not cancelled with this arrangement of field sensors but a magnetic near field from a near field source is cancelled.

    Abstract: The present invention relates to an ultra small size vertical MOSFET device having a vertical channel and a source/drain structure and a method for the manufacture thereof by using a silicon on insulator (SOI) substrate. To begin with, a first silicon conductive layer is formed by doping an impurity of a high concentration into a first single crystal silicon layer. Thereafter, a second single crystal silicon layer with the impurity of a low concentration and a second silicon conductive layer with the impurity of the high concentration are formed on the first silicon conductive layer. The second single crystal silicon layer and the second silicon conductive layer are vertically patterned into a predetermined configuration. Subsequently, a gate insulating layer is formed on entire surface. Then, an annealing process is carried out to diffuse the impurities in the first silicon conductive layer and the second silicon conductive layer into the second single crystal layer, thereby forming a source contact, a drain contact and a vertical channel. Finally, a gate electrode is formed on side walls of the vertical channel.

    Abstract: A permanent magnet structure for maximizing the flux density per weight of magnetic material comprising a hollow body flux source for generating a magnetic field in the central gap of the hollow body, the magnetic field having a flux density greater than the residual flux density of the hollow body flux source. The hollow body flux source has a generally elliptic-shape, defined by unequal major and minor axis. These elliptic-shaped permanent magnet structures exhibit a higher flux density at the center gap while minimizing the amount of magnetic material used. Inserts of soft magnetic material proximate the central gap, and a shell of soft magnetic material surrounding the hollow body can further increase the strength of the magnetic field in the central gap by reducing the magnetic flux leakage and focusing the flux density lines in the central gap.

    Abstract: A thin film transistor is disclosed comprising a piezoelectric film formed on a piezoresistive body of an ultra thin film and a gate electrode formed on the piezoelectric film. Due to the force generated from the piezoelectric film by an electric field generated according to the strength of a voltage applied to the gate electrode, a pressure is applied on the piezoresistive body to vary the resistance of the piezoresistive body. Thus, the quantity of current that flows from a source terminal through the piezoresistive channel to a drain terminal can be controlled. Since the piezoresistive body can be formed on a plane, a thin film transistor with a three-dimensional structure can be manufactured.
