A semiconductor device includes a first conduction type semiconductor substrate, a first conduction type semiconductor deposition layer, a trench, second conduction type wells, a JFET region, a first conduction type first source region, a first source region, a trench-type source electrode, a gate insulator film, a gate electrode, and a drain electrode. The drive device is disposed at the end of the belt axis of the winch. When connection with a charger is established at a time over-discharge is detected and the discharge control FET is turned off, the discharge control FET is forcefully turned on after a first predetermined time elapses. Each data object type stores information regarding the storage device. The dialog manager receives logical forms from one or more of the presentation managers and sends these to a taxonomical mapping process which matches the items of interest to the user against the content organization in the content database to match business categories and sends modified logical forms back to the dialog manager. Other embodiments are also described and claimed.
