Typical O-ring and application. An O-ring, also known as a packing or a toric joint, is a mechanical gasket in the shape of a torus; it is a loop of elastomer with a round cross-section, designed to be seated in a groove and compressed during assembly between two or more parts, forming a seal at the interface.
The interface between the "outside world" and the IC is made via the input/output (I/O) ring. This ring contains power I/O ports, digital I/O ports and analog I/O ports. The I/Os are (usually) wired via the IC package to the "outside world" and each I/O executes its own specific command instructions, e.g. JTAG ports, IC power supply ports etc
A Wills Ring or Cooper Ring is a form of all-metallic O-ring seal. They are used for extremely arduous service, such as sealing the head gasket of high performance piston engines . Hollow, metallic Wills Rings are used as they have better springback than yielding soft metal seals and higher temperature limits than elastomer O rings.
A common improvement is an inner compression ring. A compression ring allows for higher flange compression while preventing gasket failure. The effects of a compression ring are minimal and generally are just used when the standard design experiences a high rate of failure. A common improvement is an outer guiding ring.
2000s and 2010s. Flared wide-leg jeans became popular again in the early aughts, often featuring low-rise waists that eventually fell to the wayside in favor of more universally flattering (and ...
The Raschig ring is a piece of tube, invented circa 1914, [2] that is used in large numbers in a packing column. Raschig rings are usually made of ceramic or metals, and they provide a large surface area within the column, allowing for interaction between liquid and gas vapors.
