摘要:
The present invention is to solve a problem of damage to a power transmission circuit due to an increase in a supplied current by appropriately controlling transmission or cutoff of electric power from a power transmission device to a power receiving device. The power transmission device includes a power transmission circuit, a third coil 26, and a turning device. The power transmission circuit includes a second coil 24 being configured to supply a first coil 34 of a power receiving device with electric power. The third coil 26 is magnetically coupled with the second coil 24. The turning device causes the third coil 26 to turn about a turning shaft 262 that intersects with a winding shaft 241 of the second coil, to change an impedance of the power transmission circuit such that the electric power is cut off or supplied.

A variable inductor mechanism comprises a coil (1) and influencing means (15) supported on or forming part of a flexible tape (5) movable longitudinally in a direction generally transverse to the coil axis to influence the inductance of the coil (1) in dependence of the transverse position of the influencing means (15) relative to the coil axis. The influencing means (15) may be a conductive layer or any other means which is applied to or forms part of the tape (5), in a nonuniform manner, so that as different parts of the tape (5) intersect the coil axis, they will have a different influence on the coil's inductance. The mechanism is particularly suited to miniaturisation, and could be used as a wrist radio tuner (Figure 6) and incorporate a tuning scale (10) on the tape (5) visible through a window (18) in a casing (14), and the tape (5) can be advanced by the tape passing round sprockets (7) and (9), one of which is supported on a control shaft (8).

@ A coaxially aligned transformer (60) having a secondary coil (62) wrapped with a high dielectric insulating material wrapped on a support member and slidably supported between a lock block (118) and a support base to permit the transformer electrical parameters to be adjusted by sliding the transformer core. A primary coil (58) is supported coaxially about the secondary coil (62). Both the primary (58) and the secondary coil (62) coil include voltage divider segments having equal inductance with the primary coil segments (70,72) arranged in phase and the secondary coil segments (80,82) arranged 180° out of phase. The secondary coil (62) is completely insulated and isolated from ground. The primary coil (58) has a number of taps which are connected to the contacts (142) of a multi-position switch (76) so that the voltage in one of the segments of the primary coil may be varied so that the output of the transformer may be varied. This transformer provides a switchable primary circuit and a fully insulated secondary circuit.

A superconducting magnet includes a pair of superconducting coils (110), two heat shields (130) surrounding the pair of superconducting coils (110), respectively, two vacuum chambers (140) accommodating the two heat shields (130), respectively, and facing each other with a predetermined space (20) sandwiched therebetween, a magnetic shield (180) covering at least a portion of the two vacuum chambers (140), and two position adjustment mechanisms (190) supporting the two vacuum chambers (140), respectively, in a position-adjustable manner. The two position adjustment mechanisms (190) change distribution of a static magnetic field formed in the predetermined space (20) by the pair of superconducting coils (110), by adjusting relative positional relation between the two vacuum chambers (140).
