摘要： From the individual small areas of a conductor pattern arranged on the back side of a circuit board, there are individually extended leader patterns, which are midway led by through holes to the surface side of the circuit board. The individual leader patterns led to the surface side are connected with a terminal portion on the low-voltage side through jumper pads. The desired small areas are enabled to function by shorting the jumper pads with solder. The individual small areas are constituted to have a capacity of 1 pF, when caused to function, and they have such a capacity as a pattern capacitor as is proportional to the number of the shorted jumper pads.

摘要： In the winding wire at the winding completion end side, two wires are piled up vertically and wound together from the inner circumferential side towards the outer circumferential side. The winding wire at the winding start end side that has remained on the inner circumferential side is drawn forth from the inner circumferential side to the outer circumferential side so as to form a curve along the flat surface of the coil. In the crossing portions of the winding wire at the winding completion end side and the winding wire at the winding start end side, the two wires of each winding wire are superimposed and caused to cross each other in a state in which the wires are laid down transversely.
