Filed: 1996-02-20
Abstract: PROBLEM TO BE SOLVED: To protect a current path from an overcurrent by operating it as a non-inductive coil at stationary time, using a normally conductive coil, and generating self inductance at abnormality when an overcurrent flows thereby operating it as a reactor, and limiting the overcurrent flowing to the current path. SOLUTION: This overcurrent protector is equipped with a first coil 12a which generates specified electromotive force, being connected in series to a current path L, a second coil 12b which generates the opposite electromotive force on the same level as the electromotive force generated by this first coil, and an element (PTC element) 11 which has a positive resistance temperature coefficient connected in series between the first coil 12a and the current path L. A second coil 12b is connected in parallel with the series circuit of this PTC element 11 and the first coil 12a. If an overcurrent flows to the PTC element 11, the temperature of the PTC element 11 goes up, and the resistance values increases, and the balance of the magnetic flux generated in each coil 12a and 12b is lost, which produces self inductance, and it performs reactor operation to prevents the overcurrent.

Title: Estimation method for water demand
Inventor: SAITOU TADASHI
IPC: G06Q10/04
Filed: 1979-03-20
Abstract: PURPOSE: To make accurate the demand estimation, by dynamic estimation method taking into consideration past factors.  
     CONSTITUTION: Taking the matrix representing the time series and demand variation factor to the demand estimation value Y per one day as vector X and model function as f, Y=f(vector X) gives the demand estimation value. In this case, X= (A+X*). The matrix A represents the demand variation factors as time series and the matrix X* indicates the time series change of demand changing factors. When weather is considered as X, vector X 1 =(weather in the morning)T,... vector X 5 = (average temperature)T... are considered, and the difference between the day and previous day is considered as X×. As a result, since estimation for water demand of that day depending on the previous day fine or rain can effectively be reflected on the model, the accuracy of sestimation can be increased.

Title: Detector for missing of neutral conductor
Inventor: MINAMI HIROTSUGU
IPC: G01R31/58
Filed: 1980-03-14
Abstract: PURPOSE:To enable detection of missing in a neutral conductor by comparing a voltage of a voltage conductor for a neutral conductor with a given reference voltage as concentrated on one point through rectifying thereof in the same direction with a rectifier. CONSTITUTION:A neutral conductor N and voltage conductors L1 and L2 composes a distribution wire such as single phase AC 3-wire system or the like. An AC voltage is applied to the conductors L1 and L2 at an equal level for the neutral conductor while between the conductors L1 and L2 at a level two times higher than that. The voltage of the conductors L1 and L2 is outputted by rectifying it with a pair of rectifiers 2a and 2b in the same direction and concentrated on a point A. This concentrated voltage is compared with a reference voltage higher than the normal output voltage by means of a comparator 4. When the output of the circuit 4 continues to be alternately high and low in the concentrated voltage only reflecting missing in the conductor N, this missing is detected through a time limiting circuit 5. When one of the voltage conductors is missed, a load is connected with application of AC current between one of the voltage conductors and the neutral conductor, or initial voltage is delayed to be applied to one of the voltage conductors, no detection signal is generated thereby enabling accurate detection of missing in the neutral conductor without errors.

Title: Pulsation eliminator of pump
Inventor: FUKAHORI MASAHISA
IPC: F04B11/00
Filed: 1993-02-23
Abstract: PURPOSE:To enable feeding water without pulsation by providing a pulsation eliminating tank provided with a water reservoir and an air chamber adjacent to the water reservoir, opening a discharge passage of a pump in the air chamber, and connecting a water feed passage to the water reservoir to feed water. CONSTITUTION:Water discharged from a pump 2 is discharged into an air chamber 1B of a pulsation eliminating tank 1 through a discharge passage 3, becomes small droplets 6, and drops into a water reservoir 1A. Thus, pulsation inherent to the pump 2 is eliminated by changing water into droplets 6. On the other hand, the air chamber 1B functions as a pressure storage chamber to pressurize the surface of stored water and feeds water without pulsation under pressure into an injection nozzle 5 through a water feed passage 4. Consequently, it is possible to jet the water which does not cause fluctuation of pressure which accompanies pulsation inherent to the pump 2 from the nozzle 5. Also, it is possible to eliminate pulsation by forming a thin water film 8 by making discharged water collide against a ceiling 7 of the air chamber 1B.
