摘要： A cold electron emitter may include a heavily n+ doped wide band gap (WBG) substrate, a p-doped WBG region, and a low work function metallic layer (n+-p-M structure). A modification of this structure includes heavily p+ doped region between p region and M metallic layer (n+-p-p+-M structure). These structures make it possible to combine high current emission with stable (durable) operation. The high current density is possible because the p-doped (or p+ heavily doped) WBG region acts as a negative electron affinity material when in contact with low work function metals. The injection emitters with the n+-p-M and n+-p-p+-M structures are stable since the emitters make use of relatively low extracting electric field and are not affected by contamination and/or absorption from accelerated ions. In addition, the structures may be fabricated with current state-of-the-art technology.

摘要： When doing multitrack seek or a single track jump, the midpoint between the maximum and the minimum of a tracking error signal is determined. A peak detector detects the positive peak and the negative peak. These maximum and minimum values are stored in a sample and hold circuit. A summing circuit determines the midpoint between the maximum and the minimum of the tracking error signal. An operational amplifier provides a true error signal to the servo control system that provides the appropriate servo operating point. The invention is based on the fact that even though there is no absolute reference signal indicating the appropriate on-track position, the tracking servo system obtains the track error over the whole range of positions relative to track center when doing a multitrack seek or a single track jump. The appropriate servo operating point is the midpoint between the maximum and the minimum of the track error signal. This provides compensation for level shifts due to factors such as beam displacement, or detector mispositioning, changes in read/write beam profile, and disk tilt. The present invention solves the key disadvantage of the continuous groove tracking method by eliminating tracking offsets without adding additional information to the disk. It also avoids imposing overhead on the data channel. It compensates for effects of disk tilt, detector misalignment, detector and amplifier offsets, and beam decentration due to fine tracking.

摘要： An information storage system records on a medium with a magneto-optical storage layer and a ferrimagnetic control layer. A higher power write beam is used to impose an upward magnetic orientation and a lower power write beam is used to impose a downward magnetic orientation in the domain. The control layer has an initial downward magnetic orientation, the magnetization of regions of the control layer can be inverted to an upward orientation temporarily while the region is heated above a compensation temperature. The magnetization of the region is restored to its initial downward orientation upon restoration of ambient temperature since neither the higher power nor the lower power write beam heats the control layer to its Curie temperature. The distributed optical and thermal properties of the medium are selected so that, upon heating of the medium by dissipated laser energy, the peak temperature of the control layer occurs after the peak temperature for the storage layer. When the higher power write beam is used, the domain cools through its Curie temperature before the corresponding region cools through its compensation temperature so that an upward magnetic orientation is established in the domain. When the lower power write beam is used, the domain cools through its Curie temperature after the corresponding region cools through its compensation temperature so that a downward magnetic orientation is established in the domain.

摘要： An ink composition has controlled conductivity, and a digital printing system and a method of printing an ink employ an offset inkjet printing platform. The ink composition includes pigment particles dispersed in an oil-based dielectric carrier fluid with an oil-soluble dispersant. A concentration of dispersant is a fraction of a concentration of the pigment particles sufficient to render an electrical conductivity of the ink composition less than 100 pico Siemens per centimeter (pS/cm). The printing system includes an ink having an electrical conductivity less than or equal to about 300 pS/cm, an inkjet print head, a transfer medium, a developer, a remover and an image transferer. In the method of printing, the ink is nonelectrostatically jetted to the transfer medium, and developed into a fixed image. A portion of a supernatant is removed from the fixed image, and the fixed image is transferred to a media substrate.
