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.
Moreover, the cotton swab and the bobby pin actually have the opposite of the intended effect; they push the earwax further down into the ear canal where it can become stuck and lead to infection. The tympanic membrane, or eardrum, is a thin layer of cone-shaped tissue that separates the outer ear from the middle ear. It facilitates hearing by transmitting sound vibrations from the air to the bones in the middle ear. How Does It Work? The tympanic membrane is called the 'eardrum' for a reason. (Tympanum, by the way, is Latin for drum).
