摘要： It is possible to reduce the size of a magneto-optical device, increase the speed of optical control, simplify power supply structure and its control, and maintain a Faraday rotation angle in an arbitrary state even after shut-off of the excitation current. The magneto-optical device includes a magnetic yoke (10) made of a high-permeability magnetic material, the magnetic yoke including a tabular portion (16) and four pillar portions (18) protruding from one side of the tabular portion (16), a coil (12) wound on each of the pillar portions, and a magneto-optical element (14) arranged in an open-magnetic-circuit region surrounded by the end portions of the four pillar portions. A magnetic field obtained by a coil is applied to the magneto-optical element.

摘要： A high power inductance device enables a large ferrite magnetic core to be manufactured at low cost and with ease and improves heat radiation efficiency to reduce an increase in the temperature of the core. The inductance device has a ferrite magnetic core and a winding wire wound around the ferrite magnetic core and is mounted on a heat radiation structure through at least one of the front surfaces of the ferrite magnetic core. The ferrite magnetic core is made of a core aggregate obtained by arranging side by side a plurality of ferrite cores 10 having a completely-closed magnetic path structure or a quasi-closed magnetic path structure with a magnetic gap such that an interval is placed between the ferrite cores and magnetic paths are parallel to each other. The inductance device is mounted such that at least one plane surface of the peripheral surfaces of each of the ferrite cores is brought into direct or indirect contact with the heat radiation structure 18 with a metal plate 12 inserted into the interval between the ferrite cores and the common winding wire 14 wound around all the ferrite cores.

摘要： A sheet transformer wherein a coil pattern is formed on each of substrates so as to constitute a coil substrate, a plurality of the coil substrates are overlaid in multiple layers to form a primary coil and a secondary coil. The primary coil and the secondary coil are overlaid such that the middle leg cores of EE type, EI type, EER type or EIR type cores are disposed in the center of the coils and both the outside leg cores are disposed outside the coils, thereby obtaining a magnetic coupling between the coils. A higher potential side of the primary coil and a higher potential side of the secondary coil are disposed in an opposed configuration so as to face each other.
