Integrated circuits with memory elements are provided. The fan has a minimized contact area between the vibration-absorbing boss and the hub part to prevent the vibration-absorbing boss from being deformed by high-temperature heat during insert injection molding of the hub part and the blade part while assuring sufficient strength of the hub part. In certain example embodiments, the zirconium nitride andor zirconium oxide may be doped with F andor C. The support tab is biased toward the extended position and is mateable with an opposing disc drive when the disc tray is in the open position. Antibodies against the polypeptides, vectors and host cells containing the nucleic acids, methods for using the nucleic acids and polypeptides, and compositions and articles of manufacture also are provided.
