A capacitor is provided, in which an anode and a cathode are led out in a same direction, whereby ESL and ESR are lowered at high frequencies. The light-sensitive andor X-ray-sensitive sensors of the sensor arrangement are arranged in a planar distribution on a substrate, thus forming a sensitive layer. The method monitors the configuration file stored in the storage system, determines whether the configuration file has been modified, and generates a notification message to notify a first application program that the configuration file has been changed. Upon completion of execution of the job, the service provider transmits, to the server without intervening the Web browser, completion information indicating the execution result and added with the session ID. The at least one filament is located at the second opening and is configured for emitting electrons to escape the space from the first opening.
