The present invention provides a fluororesin composition, which is excellent in moldability and crack resistance, a process for preparing the composition and a cable evenly coated with the composition. The mechanical system is mounted on the chassis and configured to be moved through a range of positions responsive to operator inputs from a human operator. The media access controller includes an address filter, which includes: address filter modules, a first logic tree coupled to each of the address filter modules and configured to provide a frame drop signal for delineation between a dropped frame and an address filtered frame; and a second logic tree coupled to each of the address filter modules to provide an address valid signal. An injector system injects fuel into exhaust flowing through the second exhaust segment. A protective member can be used to protect a portion of the article during the graphic transfer process. A scanner-unit attachment portion to which the polygon scanner is attached is formed as a convex portion protruded from a bottom plate of the optical housing such that at least a planar shape of the polygon mirror is surrounded by the convex portion.
