Abstract: PURPOSE:To discriminate originating subscribers of terminating calls from specific subscribers, leased lines, and privately owned lines, terminating calls due to special service, or the like by comparing preliminarily registered originating subscriber numbers and a terminating dial number of the originating side when a call comes to an extension subscriber. CONSTITUTION:In case that the extension subscriber 3 registers a specific subscriber 2 as the object of originating subscriber discrimination, the number of the specific subscriber 2 is dialed following hooking after the extension subscriber 3 is connected to an originating register trunk (ORT)5 through a channel switch (SW)4 by dial tone connection, and thereby, extension subscriber number information 920 and originating subscriber information 921 are registered in an originating subscriber number register memory (RM)92. When a call comes from the specific subscriber 2 to the extension subscriber 3 in this state, a central controller (CC)7 compares originating subscriber information 910 with originating subscriber information 921 for extension subscriber number information 920 read out from the RM92 on the basis of terminating subscriber information 911. Since both information coincide with each other, the CC7 transmits a call signal IR2 from a signal trunk (RGT)82 to the extension subscriber 3 through the SW4.

Title: Three-phase four-wire load circuit
Inventor: SUKEHARA MASAMI
IPC: H02H9/04
Filed: 1993-08-18
Abstract: PURPOSE:To protect an inductive load against dielectric breakdown by connecting a surge protective means in parallel with a breaker side coil of the inductive load connected with the load side of the circuit breaker and a neutral side coil of the inductive load thereby suppressing high switching surge being applied to the multistage inductive load at the time of interruption. CONSTITUTION:A switching unit, i.e., a vacuum circuit breaker 1, is connected with a multistage inductive load, i.e., a step-down transformer 10, through a cable 11. The step-down transformer 10 has a neutral point 12 connected with the vacuum circuit breaker 1 through a neutral cable 13. Surge protective units, i.e., arresters 4, are connected across coils 2A, 2B, 3A, 3B between the power supply side and the neutral side of the step-down transformer 10. When the vacuum circuit breaker 1 is interrupted, switching surge voltage is generated and an excessive surge voltage is applied to each coil. Since a surge protective unit, i.e., the arrester 4, is connected with each coil, the maximum level of switching surge voltage is restricted below a protective level thus protecting the coil against dielectric breakdown.
