Systems and methods coordinate the attributes of event personnel with the needs of particular promotional events. Data that describes the arrangement of the dynamic bookmarks is received via a network. According to the invention said periodical motion is effected in an imaginary plane which extends transversely to the cutting edge and which has a first motion portion and a second motion portion following the first motion portion. The grounding member further has a grounding conductive plate for soldering with a grounding circuit of a circuit board. The cable-side connector is composed of a female connector which is detachable relative to the male connector. A gate electrode of a p-type MIS transistor includes a conductive coating film, which is formed in contact with the gate insulation film and has a Fermi level on a valence band side from a substantial center of the band gap of the semiconductor substrate, and the second metal-containing film formed on the conductive coating film and having a lower resistance than the conductive coating film.
