It is an object of the present invention to provide a communication system to provide a communication system which requires no special application for a correspondent node and has a service handoff function enabling a transfer destination terminal device to be freely used, and its configuration equipment. A positionorientation of a workpiece and a positionorientation of a tool for getting hold of the workpiece in a teaching operation, and shapesdimensions of the tool and the storage box are determined and stored in a storage device. A first reaction gas is supplied to the chamber to react with the first precursor. The baffles forming a plurality of vertically extending channels interconnected through a horizontally interconnecting channel formed between a bottom edge of the baffle and the bottom portion of the housing. To authorize installation, the first code contained in the input install key is converted into the first encrypted code in the medium, and a computer on which a program is installed obtains the first encrypted code and generates the second encrypted code by encrypting the second code contained in the install key on the basis of the first encrypted code.
