摘要： A piece-part microactuator (220), or micromotor, manufacturing approach is presented. In this approach, two of the NiFe parts (221,223) and dielectric and copper (225) piece-parts are manufactured separately. This allows the NiFe parts (221,223) to be designed in a manner to maximize the thickness of the metal, which in turn increases the magnetic properties of the motor. The dielectric and copper coils piece-part (225) may be based upon a thin film interconnect (222) or some derivative of a standard flex circuit printed wiring board. These piece-parts (221,223,225) may be tested individually, defective parts discarded, and only functional units assembled. This not only produces a mechanically balanced construction, but has lower cost due to non-sequential manufacturing steps. The dielectric and copper coils piece-part (225) also provides the path for electrical connections to the movable platform (234) and a relatively easy method for electrical connection off the microactuator and onto the hard disk drive system.

摘要： A pivoted platform has two flexible arms having rigid end zones which are attached by means of spacers to piezoelectric elements. The piezoelectric elements are made to deflect in opposite directions upon the application of the electrical signal to cause the platform to pivot. Applying voltages of the opposite polarity causes the platform to pivot in the opposite direction. A mirror may be attached to the platform to produce a scanning mirror for the vertical deflection of a television image.

摘要： A movable mirror device driven by a reluctance force motor is provided. A sheet of material has a mirror portion, a hinge portion, and a frame portion formed therein. The mirror portion is coupled to the frame portion via the hinge portion. The reluctance force motor is formed from a magnetic flux channeling circuit. A wire coiled about a portion of the magnetic circuit is used to induce a magnetic field through the magnetic circuit. Air gaps in the magnetic circuit provide attractive forces between portions of the magnetic circuit when a magnetic field is present in the magnetic circuit. The air gaps and the magnetic circuit are configured so that the magnetic attractive forces at the air gaps exert torque on the mirror portion about the hinge portion. When the hinge portion is twisted, it acts as a torsional spring biasing the mirror portion toward a neutral relaxed position.

摘要： Apparatus and methods for removing jitter and stabilizing the feed back system of a torsional hinged device with minimal changes to the system. The stabilization is accomplished by spatially isolating the pivoting mirror structure from all drive, support and packaging structures to reduce air drag. The mirror structures may be further stabilized by tailoring the drive mechanism and the position of the mechanism to produce substantially pure rotational drive torque on the mirror.

摘要： A system and method for providing resonant movement about a first axis. A functional surface supported by a first pair of torsional hinges is driven into resonant oscillations about the first axis by inertially coupling energy through the first pair of torsional hinges. The resonant movement may be moved orthogonally on the target area by a gimbals portion of the functional surface pivoting about a second axis according to one embodiment. The resonant oscillation of the functional surface is monitored to detect changes in frequency due to mass changes of the functional surface.

摘要： Apparatus and methods for removing jitter and stabilizing the feed back system of a torsional hinged device with minimal changes to the system. The stabilization is accomplished by introducing a selected amount of lateral motion (in addition to the rotational motion) by creating asymmetry in the oscillating device or the drive torque applied to the device.

摘要： Devices being controlled electronically via physical manipulation often display a resonance. In many circumstances, the frequency range of operation is not close to the resonance frequency. In these cases, the resonance can be removed through the use of simple compensation techniques such as filters. However, when the resonance frequency is close to the frequency range of operation and when the resonance frequency can change depending on temperature, time, and physical position of the device, simple compensation techniques cannot be used. The present invention presents a non-mechanical technique for providing compensation for devices with a shifting resonance. The non-mechanical technique allows for the compensation to be performed via computation.

摘要： System and method for establishing and maintaining resonant oscillations of a torsional hinged device such as a pivotally hinged mirror. The system and methods comprise a permanent magnet mounted to the pivoting mirror that interacts with an electromagnetic coil. The magnetic coil is periodically connected and disconnected from a DC power supply in response to a series of drive pulses having a timing and duration such that the magnetic forces generated by the interaction of the permanent magnet and the electromagnetic coil maintains resonant oscillations of the device.

摘要： A hard disk drive system (10) includes a rotating magnetic disk (16), and a support arm (22) which is supported for movement relative to the disk under control of a voice coil motor (21). a microactuator (26) supports a read/write head (27) on the support arm for movement relative thereto a control arrangement (13) controls the voice coil motor and the microactuator in response to position information (31), which is read by the read/write head from the disk and which indicates the position of the read/write head relative to the disk. The system is free of a sensor for detecting the actual position of the support arm relative to the read/write head or the disk.
