Abstract: In an issuing subsystem is stored a first set of authorization data including information on matching between an operator and a group the operator belongs to, and information on matching between a group and commands authorized for operators belonging to the group. As an operator enters a command, the issuing subsystem references the first set of authorization data, judges whether or not the operator is to be authorized to execute the command and, if it is judged that he or she is to be authorized, augments the command with information identifying the group to which the operator belongs, the augmented command being transmitted to an executing subsystem. The executing subsystem stores a second set of authorization data including information on matching between a group and commands authorized for execution in response to an execution request from the group.

Abstract: An electrical coil unit has a bobbin which includes two flanges, and a winding portion between the flanges, on which a coil winding is wound, and beside at least one of the two flanges, another flange is provided to form an auxiliary winding portion, and removal of the insulating film from the leader extended from the winding starting or finishing end of the coil winding is subjected in the region of the auxiliary winding portion. Thereby, the bare end portions of the leaders of the coil winding are prevented from going into the region of a winding portion of a bobbin.
