Title: Ground-fault distance relay system
Inventor: SATO SHIGERU
IPC: H02H3/40
Filed: 1988-01-08
Abstract: PURPOSE:To accurately measure a distance by compensating phase currents by considering the zero-phase current of a self-channel and the zero-phase current of its adjacent channel. CONSTITUTION:A zero-phase current (I0) flowing to its own channel L1 is compared in amplitude with a zero-phase current (I0') flowing to its adjacent channel L2, the amplitudes are judged, and the phase currents are compensated by an equation. That is, in case of I0>=I0', a compensation is conducted as a conventional one, while in case of I0<I0', a compensation with (K1+K2).I0 is conducted. Thus, since the amplitude of the compensation with the current I0' of the channel L2 is limited to ¦I0¦/¦I0'¦ times by the amplitude of the current I0 of the channel L1 against the trouble of the channel L2 as shown, a malfunction due to the zero-phase compensation of the adjacent channel as the conventional one does not occur.

Title: Cross polarized wave compensating circuit
Inventor: NAMIKI JUNJI
IPC: H04B7/00
Filed: 1985-01-10
Abstract: PURPOSE:To share a cross polarized wave by applying cross polarized wave compensation at a base band so as to avoid modification of a transmission/ reception signal for an in-use single polarized wave. CONSTITUTION:A demodulated base band signal transmitted in a horizontal polarized wave is inputted to an input terminal 400, it is retarded by delay circuits 40-43, added by variable attenuators 48-52 and synthesized. A tentative identification value is inputted by a tentative identification device 70 to an input terminal 401 in place of application of a vertical polarized wave side base band signal. Since a true identification value is obtained timewise for a signal given to delay circuits 46, 47, the true identification value is inputted from a terminal 403. Through the constitution above, only the cross transmission line characteristic from the interruption side to a desired wave side is simulated and the reduction of the cross polarized wave compensating capability due to generation of a deep fading dip at the main transmission line of the interruption side is decreased.

Filed: 1984-01-11
Abstract: PURPOSE:To increase the reliability and the life of a sealed lead storage battery by adjusting the width of separators to be longer than the distance between the inner surfaces of a battery jar which are perpendicular to the main surface of the plates. CONSTITUTION:The width of separators 7a is adjusted to be longer than the distance between the inner surfaces of a battery jar 1 which are perpendicular to the main surfaces of positive and negative plates 3 and 4 constituting a plate group so that the total width of areas of each separator 7a protruding from the plates is three times the difference between the inner surfaces of the battery jar. The end portions of each separator 7a protruding from the plates are arbitrarily folded so that they remain in the battery jar 1. Therefore the amount of electrolyte contained in the battery can be increased by 5-10% without permitting the presence of any free electrolyte. As a result, the recovery rate of the battery following complete discharge is improved and the increase in the internal resistance of the battery is suppressed. Additionally, an equal amount of electrolyte is contained in each of the separators 7a, the specific gravity of the electrolyte is equalized and the shock resistance of the battery is increased. Accordingly the reliability and the life of the battery can be increased.
