摘要:
A system for controlling fluid flow in a catheter assembly is disclosed herein. An intravenous catheter assembly has a catheter adapter and a needle hub, and the catheter adapter has an inner lumen. A septum is disposed within a portion of the inner lumen, and a slit is formed through the septum. A Parylene coating is disposed within the slit of the septum, the Parylene coating has a thickness of between approximately 0.00005 to 0.0005 millimeters. An introducer needle has a first end coupled to the needle hub and the second end extending through the inner lumen of the catheter adapter. A middle portion of the introducer needle is positioned within a portion of the septum.

A mine elevator is provided having an anti-explosion traction system, an anti-explosion lift car protection system, a flexible guide rail guiding system, a compound lift car, and a counterweight system. The anti-explosion traction system comprises a traction rope tension regulating device, an anti-explosion traction machine, and an anti-explosion control cabinet. The anti-explosion lift car protection system comprises a rope holder, a speed limiter, two hydraulic buffers, a safety clamp, a brake rope, and a brake rope tension buffer device. The flexible guide rail guiding system comprises a steel wire rope guide rail, a guide rail tension device connected to the steel wire rope guide rail and fixed to the an upper platform, a guide rail connection device connected to the steel wire rope guide rail and fixed to a lower platform, and a flexible guide rail guide sleeve fixed to the compound lift car and the counterweight system.
摘要:
A method of detecting a change in fly-height comprising measuring a first baseline position error signal (PES) at a first diameter on a disk, measuring a second baseline PES at a second diameter, measuring a first transient PES at the first diameter subsequently to the first baseline PES, measuring a second transient PES at the second diameter subsequently to the second baseline PES, determining a first change in PES by comparing the first transient PES to the first baseline PES, determining a second change in PES by comparing the second transient PES to the second baseline PES, performing responsive action when one of the first change in PES exceeds a first threshold and the second change in PES exceeds a second threshold, and generating a general error condition when both the first change in PES and the second change in PES exceed respective thresholds.

An information storage system has structure with a head that can effect information transfers with respect to a storage medium. According to one feature, a control portion monitors a characteristic of information read from the storage medium, and can take action to reduce the likelihood of non-recoverable errors based on the characteristic. According to a different feature, the control portion moves the head to a position adjacent a portion of a surface on the storage medium, waits while moving the head relative to the surface, and then moves the head to another position adjacent a different portion of the surface. According to another feature, the control portion calculates a distance of the head from the surface based on information read from the surface, and determines based on this distance whether the head or the storage medium may fail to satisfy a criteria.
摘要:
Removable cartridges employ a labyrinth-type seal design which features multiple seals for a very effective barrier to outside contaminants. The sealing mechanism of the cartridge is specifically designed so moisture and other contaminants are blocked from entering the cartridge, resulting in high resistance to corrosion and guarding against the potentially adverse effects of air borne particulate and infiltration of detrimental external gasses. Because no seal is perfect, the cartridge incorporates a charcoal desiccant inside each cartridge to provide additional protection from moisture, corrosion and out-gassing. The disk design also includes a robust recirculation filter on each cartridge to filter the air inside the cartridge each time the disk spins, effectively removing any airborne contaminants that make it past the cartridge seal.
