摘要： An electromagnetic head for a storage device comprises a magnetic core forming a magnetic circuit, and a magnetoresistive means. The magnetic core is interrupted by an air-gap, thereby separating a first pole and second pole of the magnetic core. The magnetoresistive means is disposed in the region of the air-gap, and is connected to the magnetic core so as to be connected in the magnetic circuit.

摘要： A bi-dimensional position sensor that can be advantageously used in the turn system controlled from the steering wheel of a vehicle. The sensor includes a permanent magnet fixed to a control lever so as to move in a plane along first and second directions and to rotate about a third direction orthogonal to the preceding ones. The permanent magnet is movable with respect to an integrated device including a first group of sensor elements arranged spaced along the first direction, a second group of sensor elements arranged spaced along the second direction and a third group of sensor elements detecting the angular position of the permanent magnet. Electronics integrated with the sensor elements generate a code associated with each position which the permanent magnet may assume and generate a control signal corresponding to the desired function.

摘要： An electrostatic cleaning structure of a hard disk driver is formed by a plurality of concentric conductive regions to which biasing pulse trains are supplied. Each biased conductive region generates an electric field attracting any dielectric particle. The pulse trains supplied to immediately adjacent conductive regions are phase-shifted by a predetermined time and in a direction linked to a desired direction of removal for the electrostatic particles. Voltage pulses sent to each conductive region are delayed with respect to voltage pulses sent to an immediately preceding conductive region in the direction of desired removal, and are advanced with respect the voltage pulses sent to an immediately successive conductive region.
