Abstract: To provide a scanning tunneling microscope, a probe for use with the scanning tunneling microscope, a method of treating the probe, and a method of fabricating a nano-structure, which facilitate formation of a continuous nano-structure.     A probe (2) for a scanning tunneling microscope formed of an Ag2S crystal having both ion conductivity and electron conductivity is provided. Voltage and tunnel current (6) are~ applied between the probe (2) and a substrate (3) in order to~ move movable Ag ions to thereby grow on the tip end of the probe (2) a projection (mini chip) composed of Ag ions or Ag atoms. The polarity of the applied voltage is reversed after the growth of the projection in order to return the Ag ions or Ag atoms constituting the grown projection (mini chip) into the Ag2S crystal to thereby contract the projection.    Thus, the probe (2) can have a projection composed of Ag ions or Ag atoms and having a regulated shape.     Further, the movable ions or atoms of the mixed-conductive material are transferred onto the substrate so as to form a nano-structure on the substrate.

Abstract: The invention concerns control of connections in cellular telecom-munication systems, particularly setting up and releasing of connections.  According to the invention, during setting up of a new MM connection it is checked whether an RRC connection is already active. If an RRC  connection is already active, explicit signalling is used. Otherwise, RRC  level events can be used to implicity control MM level events. During releasing of MM connections, it is checked if another MM protocol uses RRC connections, and if that is the case, the releasing of MM connections is signalled explicitly.
