Title: Subsystem diagnostic system
Inventor: NAGAO MASAAKI
IPC: G06F15/177
Filed: 1980-11-19
Abstract: PURPOSE:To prevent an ineffective communication request processing to improve the processing capability and resolve the service delay, by holding availability information of connection parts of all master and slave subsystems in each slave subsystem of the distributed processing system consisting of a loop transmission line. CONSTITUTION:Availavility information of connecting devices Al-An, Bl-Bn, Cl-Cn, and Dl-Dn of all master and slave subsystems A'-D' included in the distributed processing system are always transferred from the main subsystem A' to slave subsystems B'-D' at a prescribed period. Consequently, when a communication request is received from a storage terminal equipment T, a subsystem control table ST in the subsystem itself is referred to discriminate the  available state of connecting devices of the subsystem to be called immediately.  Thus, the ineffective communication request processing where an unoperatable  connecting device is used is avoided.

Title: Driving circuit for base of transistor
Inventor: YASUDA TETSUO
IPC: H03K17/567
Filed: 1988-07-01
Abstract: PURPOSE:To eliminate the need for the margin of a power capacity by supplying a reverse bias current to a series circuit comprising a FET and a resistor, and discharging a gate voltage of the FET as the reverse bias current increases so as to limit the increase in the reverse bias current. CONSTITUTION:A reverse bias current is fed from an input terminal 40 and outputted from an output terminal 50 via a series circuit comprising a field effect transistor FET 41 and a resistor 44. As the reverse bias current flowing to the series circuit comprising the field effect transistor FET 41 and the resistor 44 increases, a voltage across the resistor 44 rises, a transistor(TR) 45 is active to discharge the gate voltage of the FET 41 through a resistor 43. The reverse bias current is limited to a value being the base saturation voltage of the TR 45 divided by the resistance of the resistor 44 in this process. Thus, even if the power voltage is fluctuated, since no change takes place in the current limit value, it is not required to prepare excess power capacity.
