A technique is provided for loading a multiple-OS platform on a computing device, such as a personal computer or server. An insulating film is deposited so as to surround the glass substrate by means of reduced pressure thermal CVD. A method for administering a test including transmitting a registration code, receiving a print job including a test associated with the registration code and printing the test. An inner cap retaining portion is formed on an inner wall surface of the protective cap, and a force exerted by the engagement between the inner cap and the male type connector is larger than a force exerted by the inner cap retaining portion to retain the inner cap. A doped region is diffused between the pair of sidewall passivated trenches to provide low resistance contacts. The heat pipe has an end which is thermally connected to a processor of a computer.
