It is an object of the present invention to obtain an image which is focused on all portions of a sample and to provide a charged particle beam apparatus capable of obtaining a two-dimensional image which has no blurred part over an entire sample. The tubes are separated by an electrical insulator. A second handle lever is configured to rotate in the direction about a second predetermined angle of rotation to initiate a second flush of a toilet. The route list process accesses a route list to determine a port of a gateway device that can transmit the call request to the second telephony device. The ferrule is assigned to the optoelectronic module. Consequently, a post-plating treatment can be rendered unnecessary.
