A method of packaging a semiconductor component with a printed wiring board is disclosed. A cradle member is attached to the connecting member, and two securing arms are pivotally attached to the cradle member. The invention provides strong authentication, offers optional encryption of the established session, and operates without requiring special permission to reconfigure firewalls. The shutter is arranged between the alpha particle source and the measuring position. The statistical parameters may include an average the voice quality samples; a standard deviation of the voice quality samples; a mean of the voice quality samples; a percentage of the voice quality samples above a threshold; and a percentage of the voice quality samples below a threshold. In the lubricant coating device, the lubricant smoothing unit 13 rotates while being in surface contact with the outer peripheral surface of the image carrier 1 and thereby smoothes the lubricant 11 supplied onto the image carrier 1 by the lubricant supply unit 12.
