| 20120176701 | SYSTEM AND METHOD FOR MAINTAINING A LOW DENSITY GAS ENVIRONMENT IN A DISK DRIVE - A system and method for decreasing power consumption of hard disk drives through use of an external atmosphere of low density gas, such as helium, is described. An environment container reasonably resistant to diffusion and leakage of helium (container) is erected around an existing hard disk array or server, wherein a helium mixture is pumped into the container. The helium mixture within the container is maintained at a specified concentration via proper tubing and valves which may be manually or automatically controlled. The actual concentration need not be very pure in order to achieve reduced drag over the disks in each of the hard disk drives, thereby achieving reduced power consumption. The environment container is stand alone from the hard disk drives used such that an altered hard disk apparatus is unnecessary. | 07-12-2012 |
| 20130114163 | MAGNETIC STORAGE DEVICE WITH DUAL STAGE HUMIDITY CONTROL - Approaches for desiccant device having a dual stage humidity control for use within sensitive electronic equipment. Electronic equipment, such as a hard-disk drive (HDD), may comprise a desiccant device that comprises a first absorbing portion that comprises a first desiccant material and a second absorbing portion that comprises a second desiccant material. The first absorbing portion possesses a relatively rapid permeation rate for water vapor, while the second absorbing portion possesses a relatively low permeation rate for water vapor. The first desiccant material may have a relatively high rate of water vapor absorption, while the second desiccant material may have a relatively low rate of water vapor absorption. In this way, embodiments allow for the sensitive equipment to be dried out rapidly in manufacturing and yet have a slow reversible water absorption rate during operation. | 05-09-2013 |
| 20130170074 | HERMETICALLY RESEALABLE HARD-DISK DRIVE CONFIGURED FOR RECHARGING WITH A LOW-DENSITY GAS - A hermetically resealable hard-disk drive (HDD) configured for recharging with a low-density gas. The hermetically resealable HDD includes a disk enclosure (DE), a magnetic-recording disk, a head-slider, an actuator, a low-density gas, a through-hole, and a plug. The DE includes a base, and a first cover and a second cover joined to the base. The second cover is disposed above the first cover.

The sealed disk media enclosure in one example includes a media enclosure structure formed of a porous material and including a disk media chamber and a chamber aperture on one side of the media enclosure structure, one or more disk media located in the disk media chamber, a Diamond-Like Carbon (DLC) coating on at least a portion of the media enclosure structure, with the DLC coating preventing passage of gas molecules through the media enclosure structure, and a cover affixed to the media enclosure structure and substantially sealing the chamber aperture, wherein a predetermined gas or gas mixture is sealed within the disk media chamber. | 10-15-2015 |
| 20160096220 | HERMETICALLY SEALED DISC DRIVE, THERMALLY DIRECTED DIE CASTING PRESS SUBASSEMBLY, AND DIE CASTING PRESS INCLUDING THE SAME - A casting component comprising essentially no macro porosity by having the casting material fill the mold cavity with a laminar flow is disclosed. In one embodiment, the gas within the mold cavity will not be entrained when the flow is laminar. Control of this flow behavior is directly related to the microstructure and thixotropy of the alloy. The SLC slurry have a thixotropic nature and a non-turbulent way of flowing into a casting die, allowing the process to be capable of producing cast parts having thin sections, geometric complexity and close dimensional tolerances without entrapped gas porosity. The thixotropic aluminum slurry may be characterized by a uniform primary aluminum particle size in the range of 50 to 80 microns. A uniform distribution of this microstructure throughout the injected aluminum volume encourages laminar flow of the aluminum into the die cavity. | 04-07-2016 |
