The present invention provides an anti-thrombogenic and cellular-adhesion coating composition for blood-contacting surfaces. A rotation pulse is generated each time the optical disc rotates through a prescribed angle. ; and water, wherein a total amount of the solid constituents in the recording ink is in the range of 2. This is particularly suited to inductive transmission paths such as a three-phase electrical supply cable leading to downhole sensors in the oil and gas extraction industries. Catalyst systems including quaternary phosphonium salts are shown to have improved performance with respect to the amount of volatile dihydroxy aromatic compound actually incorporated into the product copolycarbonate. One CPU may be designated a master CPU, and be responsible for beginning the error handling process.
