摘要： A chromatographic plate comprising a support having a plurality of linear grooves engraved on the rear is disclosed. Each of said grooves have a uniform depth of a half or less as large as the thickness of the support and serves to guide a cutter. After the chromatographic development, the support may easily be cloven along the grooves into strips together with an adsorbent layer carried by the front of the support to give a sample holder for mass spectrometry.

摘要： A carbon nanotube synthesis process apparatus comprises a reaction tube in which a reaction field is formed, and a discharge pipe (32) arranged downstream of the reaction tube and discharging carbon nanotubes to the outside. A plurality of nozzles (34) are provided on the sidewall of the discharge pipe (32) in directions which are deflected with respect to the center (O) of the discharge pipe (32). When gases are discharged from the plurality of nozzles (34), a swirl flowing from the inner side surface along the inner side surface is produced in the discharge pipe (32). Adhesion of carbon nanotubes to the inner side surface of the discharge pipe (32) is prevented by the swirl flow and thus the apparatus can be operated continuously.

摘要： A method and apparatus to provide a retract circuit that can correspond to the tendency toward miniaturization and low supply voltage. When drive supply voltage Vcc is applied, a retract circuit charges a retract condenser Cr with boosted voltage Vup, equal to three times Vcc, generated by a booster circuit. Then, if the drive supply voltage Vcc is cut off and a VCM driver stops, the retract circuit detects power-off with a power OFF sense circuit, and provides retract delay time by a retract delay circuit. Furthermore, when the retract delay time elapses after the drive power supply is turned off, the retract driver switches the switching circuits on, discharges the retract condenser, charged at the boosted voltage, supplies discharge current to a voice coil, and retracts the head assembly.

摘要： Methods and systems for detecting and correcting for undesirable vibrations impacting the servo systems in data storage devices. A detection technique is provided wherein a detection filter is configured to scan a position signal of the servo system across a range of frequencies, and, at each respective scanned frequency, record an amplitude associated therewith. The recorded amplitudes are examined to determine whether any exceed a threshold, thereby locating a peak frequency of the vibration. Using the detected peak frequency of the vibration, a corrective filter is configured to operate about the peak frequency of vibration, thereby reducing its impact on the position signal in the servo system. Optimum detection and correction filter structures are disclosed, as are techniques for addressing filter state vectors as initial conditions as the corrective filters are repeatedly engaged during successive settle-out and track follow cycles (between seeks), as are continuous adaptation techniques for changing vibration environments.
