  • Publication number: 20140362672
    Abstract: In a rotor manufacturing method of the present invention, firstly, a rectangular magnet element whose magnetic pole direction is recognizable is formed by a magnetic material being sintered while a magnetic field is being applied thereto, and subjected to a demagnetization process, and position regulating sections are formed on the magnet element symmetrically relative to the magnetic poles. Accordingly, a magnet can be easily formed. Secondly, the demagnetized magnets are individually transported without being attracted to each other. Accordingly, the direction of each magnetic pole of the demagnetized magnets can be aligned to one direction and successively arranged. Thirdly, when a gear section is to be formed on the magnet, it is positionally adjusted by the position regulating sections so as to have a fixed positional relationship relative to the magnetic poles of the demagnetized magnet. Accordingly, the gear section can be precisely formed relative to the magnetic poles.

    Abstract: A timepiece includes a hairspring for storing the energy provided by a step motor driving circuit and a rotor immersed in a viscous fluid controls the energy released by the hairspring to provide a constant driving force for turning the display hands of the timepiece. A frequency divider circuit counts the number of clock signals produced by an oscillator. During time correction when the hands are prevented from being driven by the energy stored in the hairspring the frequency divider retains at least a portion of the count. A recoil torque provided by the hairspring and a load torque provided by the rotor are substantially balanced at all times including immediately after the time correction activities. Time delay especially immediately following the time correction activities is avoided.
