Computing devices and methods for resetting an inactivity timer of each of a first and second computing device are described. This invention’s bonding device 21 provided with recognition device is characterized in that insulation treatment is applied to a part 231 of a cover 23 positioned at the periphery of a working hole 24. Exemplary molecular glasses include polyhedral oligomeric silsesquioxane derivatives, calixarenes, cyclodextrin derivatives, and other non-polymeric large molecules. Alignment data for aligning the first 3D model with the second 3D model is generated using the camera poses of the virtual camera and the camera poses corresponding to the input photographs. The DA converter circuit converts n bit digital data to analog signals, wherein the respective bits of said n bit digital data control a switch, control charge and discharge of electric charges in the capacitance connected to said switch, and output analog signals with the offset potential used as a reference potential. Further, the periphery of the heat-dissipating body is provided with a plurality of heat-dissipating fins.
