The present invention relates to a novel galenic form of cholesterol derivative. The plug has a movable insulating member for covering the plug electrodes when the plug is connected to an outlet and for exposing the electrodes when the plug is not connected to the outlet. Because the portable phone provides shortcut paths to specific menu items for activating various functions, utilization of the portable phone is simplified in a user-friendly manner resulting in the user finding the menu path quicker. An address reading section reads the address signal from the phase of one of the optical packets output from the optical splitter section. When the front end of the platform reaches the back end of the chassis, the platform moves down, in a horizontal position, until it reaches the ground. Resistance sensing circuitry in communication with a selected nonvolatile memory cell, senses the resistance of the nanotube fabric article and provides the control signal to the write control circuitry.
