Title: Circuit breaker for neutral protection
Inventor: KOSHIZUKA TADASHI
IPC: H02H3/00
Filed: 1994-09-22
Abstract: PURPOSE: To eliminate adverse effect of a capacitor in an oscillation circuit on a DC transmission line by separating the oscillation circuit from a neutral line at the time of normal operation of a system and closing the oscillation circuit at the time of neutral protective operation. CONSTITUTION: A plurality of converters 3 are installed in a converting station in bipolar connection. The + side line 1 is led out from a converter 3 of one polarity through a DC reactor 4 while the -side line 1 is led out from a converter of the other polarity through the DC reactor 4 and two neutral lines 2 are led out from between the poles. An auxiliary circuit breaker 6 is connected, in series, between the ungrounded end of the neutral line 2 and a main circuit breaker 5 connected in parallel with an oscillation circuit 7 and an overvoltage limiter 8. The auxiliary circuit breaker 6 is opened at the time of normal system operation but closed, along with the main circuit breaker 5, upon occurrence of ground fault on the neutral line 2 thus eliminating the adverse effect on a DC transmission line.

Title: System for reduce number of times of transaction communication
Inventor: CHIJIWA HIROE
IPC: G06F12/00
Filed: 1989-09-06
Abstract: PURPOSE:To reduce the number of the times of communication and to improve the performance of a system by forming a network, which is used by the distributed system, to be ring-shaped and using a one-phase commit system when a transaction is finished. CONSTITUTION:When a transaction end request is received from an application program 5, a transaction management processing part 7 executes commit preparation in a data base 9 through a data management processing part 8. When the commit preparation processing is made successful, a transaction tree management part 6 generates a commit preparation request and transmits transaction tree information and the commit preparation request to a node B system 2, node C system 3 and node D system 4 by using a communication control processing part 10. When one node completes the commit preparation, the other nodes do not decide whether the commit preparation is completed or not, but execute and finish the transaction processing according to the response contents of the node returning the response. Thus, the number of times for communication can be reduced and the transaction processing can be executed at high speed.

Title: Lithium secondary battery and its charging method
Inventor: YAMAMOTO KEISUKE
IPC: H01M10/05
Filed: 1997-08-26
Abstract: PROBLEM TO BE SOLVED: To prevent the deposition of metallic lithium on a graphite negative electrode and to safely charge a battery by arranging a positive electrode, the graphite negative electrode capable of inserting/releasing lithium in charge/ discharge, and a reference electrode made of a lithium alloy. SOLUTION: The standard electrode potential of a reference electrode 4 is equal or near to a lithium ion potential because the reference electrode 4 is made of lithium or a lithium alloy. The fact that the potential difference between the graphite negative electrode 3 and the reference electrode 4 is zero volt or near to zero volt shows that metallic lithium easily deposits on the graphite electrode 3. During charge, the variation of the potential difference between the graphite negative electrode 3 and the reference electrode 4 is monitored, and for example, it is managed in such a way that when the potential difference has become less than the specified value, charge is finished. Thereby, the deposition of metallic lithium is surely avoided.  The potential difference between the graphite negative electrode 3 and the reference electrode 4 is preferable to be at least 0.1 V at the starting of charge, and charge is preferably finished before the potential difference drops to 0.01 V.
