    摘要: A magnetic head follows a track in a hard disk drive as positioned by micro-actuator and voice coil motor. Embodiments operate two control paths. The micro-actuator control path generates a version of micro-actuator control signal stimulating the micro-actuator. The voice coil motor control path generates a version of voice coil control signal, amplified based upon tuning gain to stimulate voice coil motor. A decoupling feedback filter decouples these control paths, using the micro-actuator control signal version. Either control path may include a notch filter. A track following command, with PES removed, directs the micro-actuator control. The servo-controller may digitally support the invention, which may include the servo-controller program system. An implementation may be optimized within a hard disk drive, possibly as part of the manufacturing process. The hard disk drive is a product of that process.

    摘要: The invention operates two control paths. The micro-actuator control stimulates the micro-actuator. The voice coil motor control path includes the voice coil motor control generating a voice coil control signal, notch filtered to remove at least one significant excitation resonance for a notch filtered voice coil control signal. Amplifying the notch filtered voice coil control signal by a tuning gain stimulates the voice coil motor. A decoupling feedback filter uses the micro-actuator control signal to create a decoupling feedback signal used to decouple the two control paths. A track following command, with PES removed, directs the micro-actuator control. The voice coil motor control is directed by the track following command, with both PES and decoupling feedback signal removed. Preferably, the servo-controller digitally supports the elements of the invention. Implementing the method may preferably include the servo-controller program system residing in an accessibly coupled memory. The invention includes optimizing an implementation within the hard disk drive. The optimization may be part of the manufacturing process for the hard disk drive. The invention includes the hard disk drive as the product of that manufacturing process.

    摘要: An IPS mode LCD device is disclosed in which a common voltage drop and delay is decreased. The LCD includes gate and data lines crossing each other to define pixel regions. Thin film transistors are formed at crossing portions of the gate and data lines. Common lines are parallel with the gate lines and common electrodes project from the common lines parallel with the data lines. Pixel electrodes connected with drain electrodes of the thin film transistors are formed in the pixel regions between the parallel common electrodes. A first common voltage supplying line applies a first common voltage or a second common voltage to a closed circuit formed by grouping the adjacent odd numbered common lines. A second common voltage supplying line applies the second common voltage or the first common voltage to a closed circuit formed by grouping the adjacent even numbered common lines.

    摘要: Provided is a high voltage transistor in a flash memory device comprising: a source/drain junction of a DDD structure consisting of a high-concentration impurity region and a low-concentration impurity region surrounding the high-concentration impurity region, the high-concentration impurity region being formed in parallel with a gate electrode at a distance spaced by a location in which a contact hole is formed, and having a rectangular shape whose width is the same as or wider than that of the contact hole and whose length is the same as or narrower than that of an active region through which the gate electrode passes. Accordingly, a current density to pass the gate electrode neighboring the contact hole portion and a current density to pass the gate electrode at a portion where the contact hole cannot be formed become uniform. A uniform and constant saturation current can be obtained regardless of the number of the contact hole.

    摘要: A leakage current measurement apparatus for measuring leakage currents is disclosed. The leakage current measurement apparatus automatically selects one of non-inductive shunt resistors of 10Ω, 100Ω, and 1000Ω and measures leakage currents of an outdoor isolation material for an ultra-high voltage. Additionally, the leakage current measurement apparatus is capable of measuring a relatively wide range of leakage currents with a relatively high precision, even at a remote location, as a measurement range is automatically adjusted within measurement ranges preset by a user when leakage currents of an outdoor isolation material change, and being protected against a surge possibly generated by an ultra-high voltage. Also, it can remotely measure in real-time leakage currents of an outdoor isolation material installed at a remote location over Ethernet.
