摘要： An electronic watch includes a power generating mechanism; a battery that is charged with power generated by the power generating mechanism; hands that include a second hand; a driving source that rotates the hands; a driving circuit that drives the driving source with power supplied by the battery; and a control circuit that controls the driving circuit. The control circuit executes a first stopping operation for stopping the driving circuit and the control circuit in a power saving mode for suppressing power consumption and when a first determination time elapses without any power being generated by the power generating mechanism. The control circuit executes a second stopping operation for stopping the driving circuit and the control circuit in the power saving mode and when a second determination time elapses while a voltage of the battery is at a level equal to or lower than a predetermined level.

摘要： The invention relates to miniature electric motors, more particularly to monophase synchronous motors of the type the motor of which includes two pole pieces respectively polarized positively and negatively by the current circulating in an energizing coil, these pole pieces having each N teeth and defining a gap in which is placed a thin, disc-shaped rotor of hard magnetic material. The rotor comprises two annular coaxial portions magnetized with respectively N and N/2 pairs of alternately positive and negative poles.These motors can be adapted to step-by-step working under constant sign pulse feed and are particularly suitable for use in cases where size and power consumption must be reduced to a minimum, such as in electric clockwork movements.

摘要： In a rotor of a micro motor, a magnet is indirectly attached to a rotor shaft by means of a pair of bushes without using any adhesive material. The pair of bushes comprises upper and lower bushes which are respectively mounted by means of an interference fit around the rotor shaft. Each bush comprises a cylindrical portion in the center of which a hole is formed, and a flange portion having around its periphery an annular notched portion. The notched portion of the upper bush is formed on a lower surface of the flange portion adjacent to the outer periphery of the cylindrical portion while the annular notched portion of the lower bush is formed on an upper surface of the flange portion adjacent to the outer periphery of the cylindrical portion, and due to the notched portions, each flange portion is provided with a certain degree of resiliency. The magnet is loosely fitted over the outer periphery of the cylindrical portions of the respective bushes and disposed between the flange portions thereof so that it is clamped between the flange portions of the bushed by means of the resiliency of the flange portions and thereby fixed between both bushes.

摘要： A clock with a rotary drive motor having a pair of axially aligned stator subassemblies with identical molded frame parts with interfitting end portions rotatably supporting a permanent magnet rotor and take-off gears. A separate axially extending U-shaped pole piece is mounted on each frame part to provide four stator poles equiangularly spaced about the axis of the rotor, and each frame part forms a coil bobbin for winding a stator coil for the respective pole piece.

摘要： A circuit for a clock having a time indicating mechanism is connected to regulate the driving of a DC motor by a predetermined amount at predetermined time intervals, so as to actuate the time indicating mechanism without being affected by the variation in the amplitude of the DC energizing voltage available for driving the motor and the variation in the load on the motor. The motor driving circuit has a timing pulse generating circuit for generating timing pulses at the predetermined time intervals, a holding circuit actuated by the timing pulse applied thereto by the timing pulse generating circuit so as to be self-held thus enabling the motor to be energized from the DC energizing voltage, and switching means, connected to the motor or the time indicating mechanism so as to be actuated when the motor is driven by the predetermined amount. The switching means is connected to the holding circuit, so that the holding circuit is deactivated to terminate the self-holding when the switching means is actuated upon completion of the driving of the motor by the predetermined amount, thereby also terminating the energization of the motor from the DC energizing voltage.
