    摘要: A liquid crystal display includes a liquid crystal panel, a drive circuit, and a power circuit. The drive circuit includes a gate driver, a timing control circuit, and a wave signal generation circuit. The timing control circuit sends a timing control signal to the gate driver and the wave signal generation circuit. The wave signal generation circuit generates a control signal according to the timing control signal, and generates a wave signal according to the control signal. The gate driver generates scan signals according to the timing control signal and the wave signal. Before the voltage of the scan signal changes from a maximum voltage to a minimum voltage, the voltage of the scan signal decreases to an invariable middle voltage that is between the minimum voltage and the maximum voltage during a fall time of the scan signal.

    摘要: A disk drive is disclosed comprising a head actuated over a disk comprising a plurality of spiral tracks, wherein each spiral track comprising a high frequency signal interrupted at a predetermined interval by a sync mark. An offset r0 representing a difference between an axial rotation of the disk and an axial rotation of the spiral tracks is estimated. Radial dependent timing compensation values are generated in response to the estimated r0. A phase error is generated in response to the sync marks in the spiral track crossings. A control signal is generated in response to the phase error and the radial dependent timing compensation values, and a frequency of an oscillator is adjusted in response to the control signal.

A composite nanoparticle can be formed by a one step process that includes: ejecting material from a bulk target material using physical energy source, with the bulk target material disposed in a liquid. Composite nanoparticles are formed by cooling at least a portion of the ejected material in the liquid. The composite fine particles may then be collected from the liquid. A product that includes composite fine particles may be formed with laser ablation, and ultrashort laser ablation may be utilized so as to preserve composite nanoparticle stoichiometry. For applications of the composite fine particles, optical properties and/or magnetic properties may be exploited for various applications.
