Title: Alarm transfer system
Inventor: NAGATA KENJI
IPC: H04M3/22
Filed: 1984-07-27
Abstract: PURPOSE:To use a few relay lines for talking effectively by cutting off forcibly a talking of a specific relay line even if all relay lines are busy so as to transfer alarm if an importent fault takes place. CONSTITUTION:The relay lines TRK0...TRKm are used for alarm transfer. The trunks give idle display to an alarm transfer device ALSND at the idle state and the ALSND uses a priority selection circuit to select one of them for alarm transfer. When the trunk selected for alarm transfer is acquired by a controller for talking, the ALSND selects a relay line TRK having the 2nd priority. Alarm transfer display and the operating TRK number are displayed to a controller (not shown in figure) so that the relay line is not selected and used for talking. A specific relay line, e.g., the TRK0 is cut off forcibly and connected to the ALSND so as to transfer alarm at the occurrence of an important fault even when the relay lines are all busy.

IPC: G05F1/56
Filed: 1986-07-04
Abstract: PURPOSE:To control an output voltage over a wide range and to prevent an overvoltage from being impressed on a transistor (TR) by comparing a voltage which is divided by a voltage dividing circuit irrelevantly to a series circuit with an output-side voltage and thus controlling the series circuit. CONSTITUTION:An input voltage e1 is divided by resistances R4 and R5 which are equal in resistance value. The resistance R5 is grounded, so the voltage at the voltage division point 21 is invariable e1/2. When an output voltage e2 is <=e1/2, diode D3 is off and a D2 is on. At this time, the collector-emitter voltages of Q1 and Q2 are VQ1CE=e1/2 and VQ2CE=e1/2-e2. Namely, the Q1 is in charge of half of the voltage E1 and the Q2 is in charge is the remaining voltage according to the voltage e2. When the voltage e2 becomes higher than E1/2, the diode D3 turns on and the D2 turns off, so that the emitter potential of the Q1 is equal to e2. At this time, VQ1CE=0 and VQ2CE=e1-e2. The value of e1-e2 becomes e1/2 on condition that e2 is larger than e1/2. Then, neither VQ1CE nor VQ2CE becomes >=e1/2 in any case.
