专利汇可以提供Electronic clock with low power consumption专利检索，专利查询，专利分析的服务。并且An astable multivibrator, driven by a solar battery or other long-term current supply, pulses an electromagnetic stepping drive for intermittently winding up a coil spring which powers a mechanical clockwork. The spring, connected to its stepping drive via a one-way coupling permitting manual rewinding, has one end secured to a leadscrew and has its other end tied to a nut thereon so that the degree of unwinding is indicated by the axial position of the nut on the lead screw. When the spring has been tightened to a predetermined extent, the nut trips an electric switch or a lever to prevent overwinding by disconnecting the multivibrator, arresting the stepping drive or decoupling that drive from its load.，下面是Electronic clock with low power consumption专利的具体信息内容。

权利要求

1. A timepiece comprising: a clockwork provided with time-indicating means; a mechanical force storer coupled with said clockwork for powering same; reloading means for said force storer including an electronic pulse generator including an astable multivibrator and a stepping drive periodically energized thereby; a supply of electric current for said pulse generator; follower means linked with said force storer for displacement dependent upon the degree of loading thereof; and blocking means operable by said follower means in a predetermined state of loading of said force storer for deactivating said reloading means.

2. A timepiece as defined in claim 1 wherein said multivibrator comprises two cascaded transistors provided with a feedback path.

3. A timepiece as defined in claim 2 wherein said transistors are of opposite conductivity type.

4. A timepiece as defined in claim 2 wherein said blocking means comprises a circuit breaker inserted in said feedback path.

5. A timepiece as defined in claim 2 wherein said supply comprises a rechargeable battery connected across said transistors and a capacitor in parallel with said battery.

6. A timepiece as defined in claim 5 wherein said battery consists of photoelectric cells.

7. A timepiece as defined in claim 2 wherein said stepping drive comprises electromagnetic coil means in series with one of said transistors and a swingable armature in the field of said coil means.

8. A timepiece as defined in claim 7 wherein said blocking means comprises a mechanical stop interposable in the path of said armature.

9. A timepiece as defined in claim 7 wherein said reloading means includes a rotatable shaft and a one-way coupling between said armature and said shaft.

10. A timepiece as defined in claim 9 wherein said one-way coupling includes a pawl and a ratchet, said blocking means being operable to disengage said pawl from said ratchet.

11. A timepiece as defined in claim 9 wherein said shaft is provided with an extension for manually loading said force storer independently of said reloading means.

12. A timepiece as defined in claim 7 wherein said armature comprises a spring-loaded member.

13. A timepiece as defined in claim 1 wherein said force storer comprises a windable coil spring and a leadscrew connected with one end of said coil spring, said follower means being a nut on said leadscrew entrained by the other end of said coil spring for axial displacement along said leadscrew.

14. A timepiece as defined in claim 13 wherein said blocking means comprises an element trippable by said nut in a predetermined axial position thereof.

15. A timepiece as dEfined in claim 14 wherein said element is an electric switch.

16. A timepiece as defined in claim 14 wherein said element is a lever.

17. A timepiece as defined in claim 1 wherein said follower means is operative to deactivate said reloading means in a position of maximum loading of said force storer.

18. A timepiece comprising: a clockwork provided with time-indicating means; a mechanical force storer coupled with said clockwork for powering same, said force storer comprising a windable coil spring, a leadscrew connected to one end of said coil spring, and a nut on said leadscrew entrained by the other end of said coil spring for axial displacement along said leadscrew; reloading means for said force storer including an electronic pulse generator and a stepping drive periodically energized thereby; a supply of electric current for said pulse generator; and blocking means operable by said nut in a predetermined state of loading of said coil spring for deactivating said reloading means.

19. A timepiece as defined in claim 18 wherein said blocking means comprises an element trippable by said nut in a predetermined axial position thereof.

20. A timepiece as defined in claim 19 wherein said element is an electric switch.

21. A timepiece as defined in claim 19 wherein said element is a lever.
