A mounting substrate for a processor includes a die side and a land side with a processor footprint configured on the die side. An information processing terminal is connected to the reading unit. One acoustic emitter and one receiver are located in a spatial region such that the sent and the reflected acoustical energy passes along substantially same vertical line between the emitter and the target. Thus, by configuring an on-vehicle communication terminal with a combination of the on-vehicle terminal and the mobile terminal, the crew can report to the information service center while securing safety in the event of an accident. The PF-containing preparations may also include a permeant, such as azone. A welded structure in which a first member and a second member are joined by welding, wherein the first member comprises a second-member joining part which is joined to the second member, and the second member comprises a first-member joining part which is joined to the first member.
