Title: Failure retrieval and monitor system for relay transmission line
Inventor: TAKAHASHI TSUTOMU
IPC: H04B17/40
Filed: 1979-04-12
Abstract: PURPOSE:To perform failure retrieval simply by the synthesized signal f2+ or -f1 by transmitting two monitor signals f1, f2, from the terminal stations, synthesizing in the relay unit. CONSTITUTION:In the relay transmission system of one line bidirectional method, the line monitor signal f1 is transmitted from one terminal station (low group transmission terminal station etc.) and the monitor signal f2 is from another terminal station (high group transmission terminal station etc.). The band pass filters 201, 202 the signals f1, f2 and produce the failure retrieval and monitor signal of f2+ or -f1 in the frequency converter 203. The signal is coupled at the output point of the low and high group amplifiers 105, 106, and f2-f1 is given to the low group band and f2+f1 is to the high group band. Accordingly, the number of relay units and failure can be monitored at each reception terminal station by only detecting the level of the failure retrieval and monitor signal. Further, the frequency of the failure retrieval and monitor signal is single enough to monitor the entire relay units, the occupied area can be less, and the line can effectively be used.

Title: Braking controller for dc motor
Inventor: TAKATSU EIJI
IPC: B60L7/22
Filed: 1978-04-18
Abstract: PURPOSE: To smoothen the change-over from dynamic braking to regenerative braking by ensuring that contraction control of armature current in response to rise in filter capacitor voltage is not effected on the change-over.  
     CONSTITUTION: During regenerative braking of a DC motor by a chopper CH, when the regenerative current has surpassed the current capable of being fed to the power source side, the difference current flows into a filter capacitor Cf. When the voltage across the capacitor Cf has surpassed a predetermined value, an overvoltage limiter OVL reduces the current instruction to contract the armature current. When the voltage across the capacitor Cf has further increased, an overvoltage detector OVD makes a thyristor Th conduct for a predetermined time T 1  to connect a resistor R as a regenerative power absorbing load, and generates through a timer T 2  a signal for stopping the function of the limiter OVL.

Abstract: PURPOSE:To improve door attachment accuracy and make readjustment unnecessary by supporting a body being carried on a slat conveyer by means of a support-lifting cylinder to prevent deformation of the door attachment position while moving forward a cart by engage-locking a hooking device on the slat conveyer. CONSTITUTION:When the cart 3, together with the slat conveyer 1, keeping a specified relative positions to each other, begins moving forward with rollers 5 rolling on a rail 7, body support-lifting cylinders 9's are actuated to lift body supporting pieces 8's fitted on the top of piston rods.
