PORTABLE MINI AC GENERATOR/DC ACCUMULATOR FOR A MINI POWER CAPACITY

摘要

Mini generator AC / battery portable DC for a mini-power capacity for a wrist watch, a pocket watch or a pendant watch, a pacemaker or a hearing aid device powered by a battery, which in the influence of the individual movement of the wearer, a mass inertia or rotor (20) is moved relative to a stator (18) not moving simultaneously with the rotor and, by applying the current principle magnetic induction and through a rectifier known in itself, a mini-DC is generated and used to power directly or temporarily accumulating a mini-current. Since a mini device has a very limited space to house a mini-generator / battery and yet it must generate enough load current, these stresses considerably affect one hand shape and also its cost price. Samarium cobalt is a very suitable material for a permanent magnet, can be applied in an isotropic and anisotropic version provided that the magnet is performed with at least four poles. Specifically, the application is interesting in a quartz watch using a magnet having four or more poles of a permanent magnet of samarium-cobalt type having an iron yoke with claw poles. However, the use of a permanent magnet (22) having an ellipsoid shape with an iron yoke (23), having as a result a cylindrical assembly may also be preferred. A removable unit comprising the generator / accumulator can be mounted in a quartz watch may be manufactured thanks to the invention, with a minimum thickness of 1.5 mm and a minimum diameter of 5 mm.
