摘要： An angular velocity sensor including a tuning-fork sensor element made of a material exhibiting piezoelectricity to have two arms formed integrally on a base and electrodes provided on surfaces of the arms. The free end of each arm is formed with an extension projecting outward in the direction of arm vibration. The surfaces of the arms lying in the direction of vibration and the surfaces thereof lying orthogonal to thee surfaces are each provided with a single electrode. When the angular velocity sensor experiences an angular velocity owing to rotation about an axis orthogonal to the plane of the tuning fork, Coriolis forces act on the arms in the same direction as or the opposite direction from that of the vibration at that instant, thereby producing a bending moment. The direction and magnitude of the angular velocity can be determined by detecting the voltages produced by the bending moment.

摘要： In an electronic timepiece having a stepping motor which drives time indicating means, a system is provided for detecting an increase in the load torque on the stepping motor above a predetermined level. When such an increase is detected, the conditions for detection of the load on the stepping motor are changed, and thereafter drive pulses of increased power are applied to the stepping motor. When the increased load is removed, this is detected under the new set of detection conditions, and a return to the original detection conditions is executed, with the drive pulse power being returned to the original level. Stability of control is thereby provided, together with immediate response to increased load on the stepping motor.

摘要： A stepping motor for use in an electronic timepiece which has a permanent magnet rotor and a stator provided with a driving coil. The stator is comprised of stator pole pieces each having assymetric portions which provide primary and secondary magnetic paths, respectively, whereby two static equilibrium positions are provided. The rotor may be stable at either one of these static equilibrium positions by controlling the supply of two-phase pulses to the driving coil so that the rotor may be rotated in normal or reverse direction. SuThis invention relates in general to stepping motors and, more particularly, to a reversible stepping motor for use in an electronic timepiece.As is well known, stepping motors, also called pulse motors, are becoming increasing employed in industrial applications due to the introduction of digital pulse techniques. Typical one of these applications involves electronic timepieces having electro-mechanical timekeeping movements which are driven by the stepping motors. Such motors are unidirectional and typically 180.degree. per input pulse. The stepping motor is usually comprised of a rotor and a stator provided with a driving coil. The stator has two pole pieces which are displaced or offset from each other with respect to a central axis between the pole pieces. With this arrangement, it is difficult to assemble the stator pole pieces so as to provide a stable operation of the rotor. In another expedient, the stator pole pieces are integrally formed with one another and shaped by stamping. This requires the provision of a complicated die for the specific stator pole pieces. In addition, the stepping motor of this type can not be driven in the reverse direction due to its inherent construction.It has heretofore been proposed to provide various types of reversible stepping motors for use in the electronic timepieces. Each of these stepping motors is usually comprised of more than three stator pole pieces and two driving coils which provide a larger construction, and is not suited for the electronic timepieces in which a minimum spacing for the stepping motor is required. Since, further, the stepping motor of this type is driven by four-phase pulses, a driver circuit is necessarily complicated in construction.It is, therefore, an object of the present invention to provide an improved stepping motor which overcomes the shortcomings encountered in the prior art.It is another object of the present invention to provide an improved stepping motor which is specifically suited for use in an electronic timepiece.It is another object of the present invention to provide an improved stepping motor which is simple in construction and easy to assemble.It is still another object of the present invention to provide an improved stepping motor which can be driven in a normal or reverse direction.It is still another object of the present invention to provide an improved stepping motor which has a single driving coil by which a rotor is rotated in a normal or reverse direction in a simple manner.It is a further object of the present invention to provide an improved stepping motor which has a single driving coil and a driver circuit arranged to apply two-phase pulses to the driving coil so as to rotate a rotor in a normal or reverse direction.It is a further object of the present invention to provide an improved stepping motor which has a single driver circuit comprised of a control switch means to control the supply of two-phase pulses to a driving coil.
