A test code is input to a test mode control circuit so that the test mode control circuit creates the test decode signal. According to one or more embodiments of the present invention, one or more virtual conference rooms are implemented by creating dedicated pathways between the users of the conference room. An information processing apparatus has: a finishing command setting unit which can set a finishing command to a printer so as to rotation-sort-output or Offset-output the document data; and a counter for counting the number of physical sheets to which the document data of one copy whose output is desired is allocated. The information may include an organizationally unique identifier, chip identification, major and minor chip revision information, and firmware major and minor revision information. A method for making a hermetic device containing a detectable gas, and an exemplary hermetic device comprising an electrochemical cell or a capacitor are also disclosed.
