摘要： PROBLEM TO BE SOLVED: To provide a communication device which can perform communication not affected by noise with an inexpensive configuration by removing the power source harmonic noise without performing conventional filtering.SOLUTION: The power source harmonic noise N has a frequency equal to an integer times of the commercial frequency fof 50 Hz. The frequency fof a subcarrier carrying a transmission signal is thereby set to a value between the power source harmonic noise frequencies equal to integer times of 50 Hz, e.g. 25 Hz and a value equal to an integer times thereof. When signal communication is performed while setting orthogonal relationship between the signal frequency (subcarrier frequency) and the frequency of power source harmonic noise, the communication signal can be taken out while being separated easily from the power source harmonic noise, and can be demodulated while removing the power source harmonic noise very accurately.

摘要： PROBLEM TO BE SOLVED: To solve the problem, wherein since a conventional laminated magnetic core is connected to a circuit earth using a pin manufactured separately to a laminated board, the number of components is increased yielding a cost, moreover, the cost of the machinery and equipment for press-fitting the pin to the laminated magnetic core is yielded.
SOLUTION: In the magnetic core 11, a punch 22 is inserted in each through-hole 12a of a first laminated board 12 laminated with a predetermined number of sheets; a terminal portion in which a notched portion 13a is protruded outward of the laminate is formed, by pushing and bending with this punch 22 the notched portion 13a of the second laminated board 13 laminated in the lower end of the laminate of the first laminated board 12. Hence, a conventional pin 3 for connecting to a circuit ground of a printed circuit board becomes unnecessary, so that it is possible to reduce the number of components and to reduce the manufacturing cost. Moreover, each conventional mechanism and control for press-fitting the pin 3 to the through-hole 2 becomes unnecessary, so that the machinery and equipment become simplified, and the cost of the machine and equipment are reduced.
