摘要： A pneumatic tool includes a housing, a driving mechanism, a rear cap, a direction controller, a speed controller, and an operating member. The housing is formed with a component chamber and an intake passageway. The driving mechanism includes an output shaft rotatable about a rotary axis. The rear cap defines a cap chamber in spatial communication with the component chamber, and has a connecting passageway that intercommunicates the cap chamber and the intake passageway. The direction controller and the speed controller are mounted in the cap chamber for rotation about the rotary axis. The operating member is coupled to the direction controller, is accessible externally of the rear cap and the housing, and is operable to drive rotation of the direction controller about the rotary axis, thereby controlling direction of rotation of the output shaft. The speed controller is operable to vary torque and speed of the output shaft.

摘要： Embodiments of the invention generally provide an electron beam substrate processing system. In one embodiment, the present invention provides an electron beam substrate processing system where a spindle shaft used to rotate substrates during processing includes at least one optical encoder wheel assembly. The optical encoder wheel assembly is configured to provide rotational speed data signal to a rotational speed control system and a pattern generation clock circuit configured to a provide an angular pattern generator clock signal and to a pattern generator circuit. The pattern generation circuit is configured to control modulation of an electron beam used for substrate processing. In one aspect of the present invention, while the spindle shaft is rotated at a constant linear velocity, the pattern generation circuit controls the modulation of an electron beam such that written mark lengths are sized to be about constant in angular dimension.

摘要： The present invention provides a method for detecting missing servo patterns on printed recording media. In general, the method first comprises the step of generating a map of anticipated servo burst patterns for a magnetic medium. The magnetic medium is typically a magnetic storage disc. Next, the magnetic medium is placed onto a disc reading assembly. Using the disc reading assembly, individual servo bursts on the magnetic medium are identified. In one embodiment, signals from the magnetic medium are processed through a frequency down conversion process, coupled with band pass filtering and rms-to-DC conversion. This enables higher throughput of signal processing. A map of identified servo bursts on the magnetic medium can then be generated. The map of identified servo bursts is then compared with the map of anticipated servo burst patterns. In this way, missing servo bursts can be detected.

摘要： The height of protrusions formed during laser texturing a glass or glass-ceramic substrate is controlled by controlling the quench rate of the protrusions during resolidification. In an embodiment, the quench rate is controlled by heating the substrate during laser texturing. Heating can be initiated prior or subsequent to, or simultaneously with, initial exposure of the substrate surface to a pulsed, focused CO.sub.2 laser beam for texturing.
