Title: Fault location system
Inventor: MORITA TOSHIYUKI
IPC: H04B17/40
Filed: 1982-04-30
Abstract: PURPOSE:To locate an intermediate repeater station which generates a code error at a terminal station of the receiving side, by transmitting consecutively the code error factor of a frame synchronizing signal with addition of a discriminating code of the intermediate repeater station. CONSTITUTION:A receiver 1 discriminates and reproduces a digital signal containing a frame synchronizing signal region F. Then the frame synchronizing signal is sampled after a frame synchronizing circuit 4 obtains the frame synchronization. The code error factor is counted by a code error factor counting circuit 5. The result of this counting is transmitted continuously to a terminal station of the receiving side with addition of a code of the number of a repeater station through a transmitter 2'. As a result, the terminal station of the receiving side can instantaneously discriminate the intermediate repeater station having a code error. This ensures location even with an incidental fault.

Title: Apparatus for improvement of stability
Inventor: REO BERUTORAMU
IPC: H02K7/118
Filed: 1987-03-28
Abstract: The invention relates to a device for improving the stability of rotation of the rotor of a single-phase synchronous motor mounted in an apparatus housing. The motor exhibits an average motor torque on which strong alternating torques are superimposed and which drives a preferably rotating load. The rotating load may be a small domestic appliance such as a citrus-juice extractor, a knife sharpener, or a dry-shaver with rotatary cutters. The device is constructed in such a way that the rotor is influenced by an additional mechanical compensation torque which acts outside the load-transmission path and which counteracts the electro-mechanical alternating torques of the motor for a given, preferably positive, direction of rotation of the rotor, the positive direction of rotation being that direction in which the torque exerted on the rotor by the current becomes initially zero and in which subsequently, shifted through a small angle, the magnetic detent torque, which exists when the stator coils are not energized, also becomes zero. And in this position a stable rest position of the rotor is provided and the opposite direction of rotation is blocked. Blocking is effected by means of a unidirectional device.
