    摘要: A method for preparing carbon nanotubes for synthesizing carbon nanotubes, fabricating carbon nanotube films and electronic devices is provided. The method for preparing carbon nanotubes can repair the defects in side walls of carbon nanotubes under stable condition easily and prepare carbon nanotubes of excellent properties. The method utilizes uric acid solution or ammonia water to treat carbon nanotubes after acidifying the carbon nanotubes by refluxing with nitric acid. The treatment temperature is, for example, 25° C.˜90° C., and treatment time is at least two 2 days. Preferably, the carbon nanotubes are treated with thionyl chloride solution before being treated with uric acid solution or ammonia water.

    摘要: To perform multi-pattern searching, a preprocessing engine populates a SUFFIX table, a PREFIX table and a PATTERN table. The SUFFIX table combines data conventionally stored in SHIFT and HASH tables. Pointers in the SUFFIX table refer to corresponding segments in the PREFIX table. Each PREFIX table segment is sorted by a prefix hash. A PATTERN table includes a hash of each full pattern sorted and grouped into segments, with each segment corresponding to a suffix hash and prefix hash combination. Pointers in the PREFIX table refer to corresponding segments in the PATTERN table. The PREFIX and PATTERN can be kept in secondary storage, allowing potentially billions of patterns to be used. After preprocessing, patterns are evaluated against a source file. A document metric is determine to qualitatively describe the similarity between the source file and each pattern file.

    摘要: A heat sink assembly includes a first heat sink, a second heat sink, and a wire clip connecting the first and second heat sinks together. Each of the first and second heat sinks includes a base and a plurality of connecting members extending upwardly from the base. The wire clip includes a pivot portion and a pair of pressing portions extending from opposite ends of the pivot portion towards each other. The connecting members of the first and second heat sinks cooperatively clasp the pivot portion of the wire clip. The pressing members of the wire clip resiliently abut against the connecting members of the first and second heat sinks and push the connecting members of the first and second heat sink outwardly away from each other. The bases of the first and second heat sinks clamp an add-on card therebetween.

    摘要: A method for calibrating a fly height adjustment device comprises flying a magnetic transducer coupled with a head gimbal assembly at a fly height from a magnetic recording data track. The magnetic transducer is coupled with a fly height adjustment device. Read-back signal amplitude is read from the magnetic recording data track with the magnetic transducer. The fly height is decreased with the fly height adjustment device. A linear fly height prediction is generated from the read-back signal amplitude and from power delivered to the fly height adjustment device as the fly height is decreased. The power delivered to the fly height adjustment device is compared with a difference between the linear fly height prediction and an implied fly height from the read-back signal amplitude, thereby calibrating the fly height adjustment device.
