Bolt holes 23 are provided for press fitting and securing bolts 5 for mounting a brake rotor 4 to a flange 22 of a hub wheel. CDC circuits include footprint compatible circuits having different delay characteristics, which may be included as part of a standard cell library for designing integrated circuits. The projections are formed at positions near the outer edges of the plate, which are distant from the center of the plate at which no projection is formed, and which are at equal distances from the center of the plate. w, x, y\u22671 and the mole ratio of x to is about 0. A heat exchanger may include at least one second locking feature receiving the other of the first locking feature and the second locking feature to automatically attach the heat exchanger to the support base when the heat exchanger is moved a second predetermined distance relative to the support base.
