An electronic system, connection failure reporting system and related methods. The substrate has a first surface and a second surface opposite to the first surface. In accordance with the invention, means are provided so that, in the operating state of the processing apparatus, a predetermined amount of the granular substance can be conveyed from the main container as working powder to the storage container in such a way that at least a minimum amount is available as a granular substance in the storage container. The instrument includes at least a first cutting guide and an adjustment mechanism operable to change the position of the cutting guide relative to the bone. Hence, the optical-information transmitting, lighting apparatus 2 can convert every place where an existing type lighting apparatus is used, into an optical communications space. Furthermore, the upper plate and the lower plate of the capsule are configured such that the upper and lower plates are vertically aligned with each other at outside ends of extensions thereof.
