Title: Faucet piece
Inventor: MATSUMURA YOSHIHIRO
IPC: E03C1/042
Filed: 2000-08-10
Abstract: PROBLEM TO BE SOLVED: To prevent water leakage from being caused by adhesion of foreign matter by providing a projection that can be loosely inserted into a communication hole of a valve seat on an operation surface of a faucet piece packing, and making the projection length longer than a clearance width between the outer surface of the projection and the inner periphery of the communication hole. SOLUTION: Clearance between the outer surface of a projection 15 and the inner surface of a communication hole 23 is about 0.3 mm wide. When a lift amount A of this faucet piece 10 is shorter than a projection length C, flow passage width of the communication hole 23 is throttled to about 0.3 mm, and any foreign matter G with an about 0.3 mm diameter cannot intrude. When the lift amount A is substantially equal to the projection length C, the foreign matter G is stopping in a communication hole 23. Here, when the faucet is in water stopping state, the foreign matter G is pressed by the projection 15 and goes away from a valve seat surface 26. When the lift amount A exceeds the projection length C, the foreign matter G instantly passes between the lower surface of a packing 12 and the valve seat surface 26.  Even a large foreign matter (g) is pressed by the projection 15 or instantly passes depending on the lift amount A, and therefore, non-preferable size of foreign matter G, (g) can be prevented from adhering to the valve seat surface 26 regardless of the lift amount A.

Title: Ground fault current direction deciding method and ground fault current directional relay
Inventor: FUJII MASAHIKO
IPC: H02H3/347
Filed: 2000-08-29
Abstract: PROBLEM TO BE SOLVED: To solve the problem that a low level zero phase voltage accident is hard to detect when deciding the direction of the ground fault current by comparing the phase of the zero phase voltage and the zero phase current. SOLUTION: Phase voltage detectors to the ground 1R, 1S, 1T detect the voltages for respective phases. A zero phase current transformer 2 detects the zero phase current of the distribution line. A ground fault direction relay 3 detects the phase voltage and using it as the reference decides the direction of the ground fault current by comparing the phase of the zero phase current detected by the zero phase current transformer and this reference voltage. When the ground fault accident is not serious, the direction is decided on the basis of the voltage to the ground, but when the accident becomes larger with the increasing zero phase voltage, the phase of the zero phase current is also compared using the zero phase voltage obtained putting together each voltage as the standard.  Besides, the phase voltage detector also obtains the voltage of the remaining phase after detecting the voltages for the two phases out of the three of the distribution line.
