Title: Common line network maintenance management system
Inventor: IKEDA SHINICHI
IPC: H04M7/06
Filed: 1990-02-13
Abstract: PURPOSE:To collect and display information other than a bypass route of a maintenance signal and maintenance information by setting an exchange number of its own exchange and passing station information into a maintenance signal relating to each exchange through which the maintenance signal passes, transferring the signal the a succeeding exchange and allowing a destination exchange to analyze and display the common line test maintenance signal content to be received. CONSTITUTION:In the case of conducting test and maintenance with a common line test maintenance signal for a common line network, in exchanges EX1-EX5 through which the common line test maintenance signal passes, the exchange number of its own exchange and passing station information are set in the common line test maintenance signal and the resulting signal is transferred to a succeeding exchange. Then a destination exchange EX1 (EX5) analyzes and displays the received content of the common line test maintenance signal on a maintenance terminal equipment MAT1 (MAT5). Thus, a passing route of the common line test maintenance signal is recognized from the setting order of the exchange numbers and a fault of the exchange, presence of bypass and a fault cause are easily recognized from the passing station information.

Title: Pad device
Inventor: YOSHII TETSUJI
IPC: G11B23/087
Filed: 1984-02-21
Abstract: PURPOSE:To secure the excellent responding capability to a composite or double head as well as to a single head by supporting the pads at plural dogleg-shaped bent parts and plural pad support surfaces formed at both sides of each bent part. CONSTITUTION:A dogleg-shaped bent part 8 is formed at the center of a pad spring 5, and a combination head 12 has a contact with a pad 4. No disturbance is given to the tape driving path for a tape running between two heads since the pad 4 is set backward at its center part. This secures a correct head touch. Thus a single head 13 can also have a contact with such pad device. A satisfactory head touch is secured despite a relative horizontal shift produced between the pad device and both heads 12 and 13 since the part 8 has an extremely small bending degree.

Filed: 1983-02-28
Abstract: PURPOSE:To eliminate almost completely the system failure of a looped data transmission network by reconstruct one long loop by a loop-back line even in case of an erroneous transmission originating from a fault of a signal line. CONSTITUTION:When a signal received from a high-order station through the signal line is disconnected the loop-back control part 5 of said station operates a disconnection detecting circuit 11 to output a signal with a logical level ''1''. This signal with the logical level ''1'' serves as the control signal of an OR circuit 13 and the 1st switching circuit 14 regards the digital receive signal of a signal converter 4 which converts a transmission line signal received through a low-order station through the loop-back line as the receive data of the station. The signal with the logical level ''1'' outputted by the OR circuit 13 is inverted by an inverter circuit 18 to a logical level ''0'' to obtain a control signal, which permits an AND circuit 19 to stops the transmission of a signal to the high- order station through a signal converter 2 and the loop back line. Thus, one large data highway from the high-order station to this station is constituted by the loop-back line and the transmit data sent out of the high-order station through the loop-back line is received by this station.
