摘要： In an antenna coil device 11, a coil portion 12 having a lead wire 2 wound around a magnetic core 1 is mounted on a case 3 made of plastic resin, and on one side of the case 3, terminal boards 4 and 5 that electrically connect one end and the other end of the lead wire 2 of the coil portion 12 to an external device are placed in a protruding manner. A through hole 4D is provided in an inserting end portion 4C of the terminal board 4, a through hole 5H is provided in a central flat portion 5G of the terminal board 5, and the two through holes 4D and 5H are placed opposite each other. This reduces stray capacitance caused between the two terminal boards 4 and 5 connected to both ends of the coil portion 12, and allows a self resonance frequency band where an impedance is equal to or above a predetermined value to be shifted to a high frequency side.

摘要： This is a small-sized transformer that is made easily. Two bobbins around which a secondary coil is wound insert into bobbin protrusions from the opening surface side of the first core whereby the two bobbins are positioned in a row. A coiling protrusion around which to wrap a primary coil is formed in the aforementioned first core. Part of the primary coil coils around the coil protrusion and the remainder is positioned and coiled in a groove of the aforementioned first core provided in the outer circumference of the two bobbins. A second core is positioned in a countering position to the opening surface of the aforementioned first core so as to cover the aforementioned three protrusions.

摘要： An inductance device comprises a drum core having a center core, and flanges integrated therewith. The center core is wound with a wire, whereas a magnetic gap is formed between the upper flange and lower flange. The magnetic gap is closed with an insulator, mixed with a magnetic substance, having rubber elasticity. The insulator comprises an overhang and an insertion integrally formed therewith. The overhang presses a region in the upper flange so as to hang from this region. The insertion tightly fits into the magnetic gap.

摘要： An electrical stimulator is provided including: a base wire configured with a core wire and an outer winding wire wound around the core wire with the core wire serving as a winding axis. The core wire is entirely coated by an insulating film, and an annulus is formed by spiraling or looping the base wire. One end of the core wire is electrically connected to one end of the outer winding wire. The other end of the core wire is connected to a first terminal of an external circuit. Further, the other end of the outer winding wire is connected to a second terminal of the external circuit. Thus, the annulus can apply an electrical stimulation to a living body.

摘要： A magnetic resonance member 1 includes a crystal structure and is capable of electron spin quantum operations with microwaves of different frequencies corresponding to arrangement orientations of a vacancy and an impurity in a crystal lattice. A magnetic field transmission unit 4 senses a measurement target magnetic field at plural measurement positions different from each other, and applies application magnetic fields corresponding to the measurement target magnetic field sensed at the plural measurement positions to the magnetic resonance member 1 along respective different directions corresponding to the aforementioned arrangement orientations. A measurement control unit 21 controls a high frequency power supply 12, and determines detection values detected by a detecting device (an irradiating device 5 and a light receiving device 6) of the physical phenomena corresponding to the plural measurement positions. A calculation unit 22 calculates the measurement target magnetic field at the plural measurement positions on the basis of the detection values.
