The present invention relates to lubricants and magnetic disks having the lubricant applied thereto, and more particularly to lubricants having excellent resistance to decomposition.With increases in the recording capacity of magnetic disk devices, the distance between the magnetic disk serving as a recording medium and the head for recording information or playback becomes almost nil close to contact therebetween. Disks are rotated also at increased speeds, so that the contact between the disk and the head tends to produce an ever increasing impact.To reduce the impact of contact, efforts have been made to provide carbon protective films which are appropriate in surface roughness and strength and lubricant films having an appropriate thickness and to ensure a proper composition ratio between the bonded layer and the mobile layer. Especially the lubricant film which is positioned on the outermost surface of the disk needs to satisfy requirements which include, besides the reduction of impact of contact, prevention of the contamination of the ...

Antipathogenic Guanidinium Copolymer

Принадлежит:

Antimicrobial, substituted alkyl guanidinium polymers, and methods to form same. Applicant's invention relates to a guanidinium polymer that is effective as a broad-spectrum disinfectant capable of immobilizing and/or killing pathogens, including active bacteria and dormant bacteria spores.The presence of certain types of bacteria and other pathogens, whether airborne or on exposed surfaces, creates a health risk. These pathogens may be naturally occurring in the environment or may be introduced by a sick or infected personal or animal. The risk of harm from pathogens is particularly a concern in healthcare settings, such a hospitals and nursing homes, where individuals are more likely to have weakened immune systems. Certain pathogens may be “weaponized,” and used as biological agents against both civilian and military personnel. These include anthrax () and botulinum ().To minimize the risk of harm as a result of exposure to bacteria, it has been a goal to develop substances and/or treatments that are effective in reducing or eliminating harmful bacteria. For instance, disinfectants are commonly applied to surfaces (i.e., floors, walls, work surfaces, and the like) to reduce or eliminate any exposed bacteria. These disinfectants, however, generally reside only on the surface and are, as such, easily washed away or otherwise removed. Such disinfectants must be periodically reapplied to maintain their effectiveness.Bacteria exist in either an active or a dormant state. In the active state, often referred to as the “vegetative state,” the bacteria is capable of growing and reproducing. It is in this state that the bacteria causes infections and illnesses. In the dormant state, often referred to as “spores,” “endospores” or “microbial cysts,” the bacteria is surrounded by a very tough outer coating. A bacteria spore requires little or no nutrients, can survive for a long period of time in harsh conditions, and is resistant to ultraviolet radiation, high and low ...

Antimicrobial and/or antifungal surfaces are usually designed by impregnation of materials with biocides that are released into the surroundings whereupon microbes are killed.leafspot, for example, overwinters in the soil on decomposing soy bean leaves from previous uninfected soy bean crops and on weed residues. When conditions are favorable, that is, high temperatures and humidity, spores are produced and are blown onto or splashed on soy bean leaves, where the spores germinate and infect the leaves.

The presently disclosure technology is directed to monitoring a hard disc drive for narrow band dwell, and in some implementations, implementing operations to mitigate narrow band dwell. More specifically, the presently disclosure technology may detect an overflying air-bearing slider position, apply a lubrication film displacement formula to a narrow band of the storage platter, apply a lubrication film reflow formula to one or more other narrow bands of the storage platter, and track lubrication film thickness over time in each of the narrow bands of the storage platter. 1.
