Technology exchange agreement with Intel. Intel had introduced the first x86 microprocessors in 1978. In 1981, IBM created its PC, and wanted Intel's x86 processors, but only under the condition that Intel also provide a second-source manufacturer for its patented x86 microprocessors.
The ear canal is shaped somewhat like an hourglassnarrowing part way down. The skin of the outer part of the canal has special glands that produce earwax. This wax is supposed to trap dust and dirt particles to keep them from reaching the eardrum.
A ruptured eardrum â or perforated tympanic membrane as it's medically known â is a hole or tear in your eardrum, the thin tissue that separates your ear canal from your middle ear. A ruptured eardrum can result in hearing loss. A ruptured eardrum can also make your middle ear vulnerable to infections or injury. A ruptured eardrum usually heals within a few weeks without treatment. Sometimes, however, a ruptured eardrum requires a procedure or surgical repair to heal.
