Abstract: A pendulum stem (16) not more than 4 inches in length has one end portion swingably connected to a pivot arrangement (18) and a concentrated mass (22) slidably located on the other end portion. Permanent magnets (56,58) secured to the mass (22) move past a pair of wire coils (60,62) during swinging movement of the stem and mass to induce a signal in the one coil (60). The signal actuates a circuit (66) to form a pulse that is applied to the other coil (62) at an appropriate later time to create a magnetic pulse driving the mass (22) and stem (16) along its swing path. The described pendulum drive applied to a miniature clock provides a slow-swinging pendulum having a period closely approximating that of a grandfather clock many feet in height.

Abstract: The control mechanism for displaying hours and minutes includes a tilting member (15) biasing against, under the effect of a return spring and via a pawl (18), a spirally shaped cam (12) located at the center of the movement, and which makes a full rotation in one hour. The tilting member (15) is lifted progressively by the action of the cam (12) to fall back instantly, once each hour. During this instantaneous falling back motion of the tilting member (15), a toothed sector (23) carried by the same drives, via a train of gears (24, 25, 26), a central pinion (27) carrying the minute hand. Thus, once at each hour, the minute hand is instantly reset to its initial position. The tilting member (15)carries a pawl (30) cooperating, at each of the instant falling back motions of the tilting member, with a star wheel with twelve branches, which rotates at the center of the movement and which carries a disk indicating hours, of which the display it thus of the so-called "incremental" type.

Abstract: In an electronic watch, a hand wheel gear 109b in a gear train has a tooth 124 having a profile K so as to prevent the backward movement of a hand 104. During initialization, the gear train is rotated backward such that the hand 104 is turned to the backward movement preventing position, which serves as an initializing position, and a reference position during detection of a hand position. Usually, a backward movement command is issued when the hand 104 is supposed to be at the reference position. The hand 104 is judged to be out of the reference position when its backward movement is detected.

Abstract: A rotationally symmetric timepiece wherein time information is displayed along an axis that is marked in 13 locations with axially symmetric markers. The 13 markers divide the axis into 12 sections of preferably equal length as well as mark the ends of the axis. Time information is displayed by one or more indicators which move along the axis at controlled rates. To display hour information, an indicator, which encircles the axis, is moved along the axis at a speed such that it travels the full length of the axis in a 12-hour period. At the end of this period, the indicator is preferably reset back to the first indicator. To display minute and second information, two additional indicators are used. The minute indicator is made to travel the length of the axis every hour before being reset, while the second indicator travels the length of the axis over a period of one minute before it is reset. The indicators are of different diameters so they do not interfere with each other as they travel along the axis.

Abstract: An analog electronic timepiece having a function by use of which a plurality of predetermined times as well as a mode change can be visually informed so that they are easily understood by hand movement and sound generation. When a judgement circuit judges a predetermined condition of the timepiece, such as time coincidence with a preset alarm time and/or mode change, the judgement circuit outputs a starting signal of the hand movement and sound generation. An information signal generation circuit produces timing signals for driving the hands and generating sound in response to the starting signal. An information signal generating circuit outputs an operation generation signal to a motor driving circuit and/or a sound signal generating circuit according to preselected numbers of hand movement operation steps and frequencies of sound generation read out from an information operation storing circuit.

The power supply elements and external terminals are supported in the upper housing half. The elapsed time hour meter is versatile and reliable and has the advantages of being small in size, low in cost, and low in power consumption.

Abstract: The stator of the motor comprises two pole pieces (1, 2) which are axially staggered. An axially magnetized cylindrical rotor (5) is disposed in the openings or bores of said pole pieces. The rotor (5) is provided with an external toothing (3) which is continuously engaged with an internal toothing (4) of the stator. In the unexcited stator, the rotor (5) assumes a stable position by attraction to the pole pieces (1, 2).

The toothings (3, 4) stay in engagement during said displacement, resulting in an angular displacement of the rotor, the angle being defined by the difference of the number of teeth of said toothings (3, 4). The motor allows a miniaturization and a simple control by alternating pulses of opposed polarities.

Abstract: A stepper rotor is driven with a narrow pulse width input which matches the load conditions on the motor. The subsequent position of the rotor is detected as being rotated or non-rotated by application of a detection pulse to the rotor. An additional driving pulse of increased width is applied should the rotor be found in a non-rotated state. A stabilizing pulse prevents intermediate rotor positioning. Position of the stepper motor is detected by passing a current through the rotor cell. The rate of increase in detection current is different when the rotor has rotated and when the rotor does not rotate because coil inductance and magnetic flux directions passing through the saturable portion of the stator are different depending upon the position of the rotor. The width of the driving pulse for normal operation is selected from a range of pulse widths so as to match the load on the motor.
