A communication control apparatus that enables a personal computer usually connected to a LAN when in use to be connected temporarily to the same LAN from a different location and via a different communication device, while ensuring security without time and effort spent on configuration. In a LDO regulator, lowering the Vt of the pass transistor with load increases the level of drive that can be applied to the pass transistor thus allowing a smaller transistor to be used for the same load. The side accordion members can be designed to replicate air conditioner side accordion members. At that new location, the detection circuit is isolated from the effect of magnetic risers, large temperature swings and other undesirable phenomenon that often affect magnetostrictive probe measurements that are referenced to the canister.
