The present disclosure relates to electronic devices that include a composition that actively generates a gaseous oxidizing agent component within the interior gas space of the electronic device. The present disclosure also relates to electronic devices that include a container that includes a gaseous oxidizing agent component in a manner that the gaseous oxidizing component can transfer from the container to the interior gas space of the electronic device. The present disclosure also involves related methods.

Described are enclosures for electronic devices; the enclosures include a cover, a base, and a snap-fit engagement between the cover and the base; also described are methods of preparing the devices.

Described are methods for forming a friction stir weld between a steel piece and an aluminum piece, with specific examples of the steel piece and the aluminum piece being a cover and a base of an enclosure.

The present disclosure relates to a gas filtering device that allows to cover and filter gases emanating from liquid and/or solid substances without the use of auxiliary technologies. The gas filtering device comprises an air tight geomembrane that is adapted to cover and seal the surface from which the gas emanations come from, one or more air permeable filtering cartridge pocket(s) embedded within the air tight geomembrane that are adapted to adopt an opened configuration and a closed configuration, and one or more corresponding filtering cartridge(s) that are releasably secured within the air permeable filtering cartridge pocket.

Provided is a PSA sheet having excellent moisture resistance with reduced gas emission.

The sheet body provided by this invention is a laminate sheet body having a PSA layer on at least one face. The sheet body has a moisture permeability of less than 90 g/cm.sup.2 per 24 hour measurement period in in-plane direction of bonding interface of PSA layer, with the sheet body having an internal volume (bulk) forming a permeation channel that has a prescribed length of 2.5 mm, the moisture permeability determined based on a modified MOCON method, at a permeation cell temperature of 40 C., with humidistat gas at a temperature of 40 C. and 90% relative humidity supplied to a wet chamber. It also has an amount of thermally released gas of 10 g/cm.sup.2 or less, determined at 130 C., over 30 minutes, by gas chromatography/mass spectrometry.

According to one embodiment, a disk device includes a disk-shaped recording medium, a base accommodating the recording medium, the base including a bottom wall, a sidewall on a peripheral portion of the bottom wall, and a rib on a part of an upper surface of the sidewall, a first cover on a part of the upper surface of the sidewall, and a second cover on a first surface of the rib and above the first cover. The rib includes a first region with a first width, a second region with a second width less than the first width, and the first surface with a fixed width around an entire circumference of the rib. The first region and the second region are located corresponding to a side portion of the recording medium.

A disk drive, has a housing structure enclosing a disk and at least one recording head. The drive includes a plurality of capsules each comprising oxygen gas enclosed within a membrane. An oxygen diffusion rate of the membrane is selected to release oxygen into the housing structure at a rate that compensates for oxygen depletion within the housing structure.

A hard disk drive includes a base deck, a cover coupled to the base deck to create an internal cavity, and a testing assembly coupled to the cover. The testing assembly includes a housing and is arranged to expose an organic material, for example grease or oil, to the internal cavity.
