A coupling loop circuit is constructed in such a way that a sixth conductor is made to three-dimensionally cross a second conductor, an eighth conductor is made to three-dimensionally cross each of the second conductor and a fourth conductor, a first loop area and a second loop area spatially overlap each other, and an overlapping area between the first loop area and the second loop area is formed by the second conductor, the fourth conductor, the sixth conductor, and the eighth conductor.

Coupling loop circuit, noise filter circuit, and circuit generation method

A noise filter includes a magnetic core including a magnetic material; and a distance adjusting member that accepts adjustment of a distance between a loop portion and the magnetic core, the loop portion being a portion of one or more conductor wiring lines wired in loop shape out of a first conductor wiring line and a second conductor wiring line.

An input loop line () is disposed in a region inside or outside the loop of an output loop line () as viewed in the thickness direction of a dielectric layer ().

Noise filter circuit

A positive electrode side input loop line () and a positive electrode side output loop line (), and a negative electrode side input loop line () and a negative electrode side output loop line () form two sets of coupling loops, and the loop lines of the two sets have the same winding direction, and have the same loop sizes of and relative relationship between the loop lines. A capacitor () is connected in series between the positive electrode side input loop line () and the negative electrode side input loop line ().

A dual-mode choke coil includes: a lower core that has a first through fourth columnar body; a first upper core and a second upper core; a first coil in which two coil conductors are respectively wound onto the first columnar body and a third columnar body in mutually different directions and are connected in series; and a second coil in which two coil conductors are respectively wound onto a second columnar body and the fourth columnar body in mutually different directions and are connected in series, and in which the winding direction of the coil conductor of the second columnar body is the same as that of the coil conductor of the first columnar body. With this configuration, both common mode noise and normal mode noise can be reduced.

Cleaning of a hot dip galvanized steel sheet is conducted by bringing a strip-shaped steel sheet which was treated by surface oxidation in advance into contact with a cleaning liquid for 1 second or more, and then bringing the hot dip galvanized steel sheet into contact with pure water, while continuously transferring the hot dip galvanized steel sheet. The method allows efficiently and fully washing off the acidic solution adhered to the surfaces of the hot dip galvanized steel sheet treated by surface oxidation. The invention also provides an apparatus for cleaning the hot dip galvanized steel sheet to carry out the above cleaning method.

A method of controlling the concentration of P of cleaning solution waste water starts by providing a waste water buffer tank capable of either sending the waste water to a waste water treatment plant or storing the waste water after the waste water is accepted. The concentration of P in the cleaning solution is set within a target concentration range, and matter to be treated is treated. The concentration of P in the waste water is measured in the waste water buffer tank. When the measured value of the concentration of P is less than a selected upper limit, the waste water is sent from the waste water buffer tank to the waste water treatment plant. When the measured value of the concentration of P is higher than the selected upper limit, sending the waste water to the waste water treatment plant is stopped, and the waste water is stored in the waste water buffer tank. The concentration of P is reduced to a value within the target concentration range, and the matter to be treated is treated.
