A jumper is provided as a control input means for switching operation modes of a CardBus controller. An eccentricity phase of each of the photosensitive drums is calculated based on the positional deviation detected, and a rotational phase of the photosensitive drums is controlled based on the eccentricity phase calculated. The precursor glass may be encased in a gas-permeable medium. The pin has a locked position where the pin shoulder abuts the shoe shoulder whereby the pin locks the shoe in place and an unlocked position where the shoe shoulder may translate through the clearance defined by the reduced circumference section. The processes can result in dual pre-doped gate stacks having essentially vertical sidewalls and further having a width of at least about 3 nm, such as from about 5 nm to about 150 nm.
