摘要:
The present invention concerns a timepiece such as, in particular, a wristwatch, including a watch movement, a running equation of time device, as well as a date mechanism, this timepiece having a pair of hour (22) and minute (24) hands which indicate the civil time, and an additional minute hand (28) which indicates the true time, the daily position of the true time minute hand (28) with respect to the civil time minute hand (24) being determined by the position of an equation of time cam (32) driven in rotation at the rate of one revolution per year by a date mechanism, characterized in that the true time minute hand (28) is driven by a differential gear (50) which has for respective power take-off a gear train (52) driving the civil time minute hand (24) and a transmission member which co-operates with the equation of time cam (32) to transmit the pivoting movement of said cam (32) to the input of the differential gear.

An electronic timepiece has a wheel train mounted for undergoing rotation and a transmission wheel for undergoing rotation in accordance with rotation of the wheel train. A contact point spring is connected to the transmission wheel for rotation therewith. The contact point spring extends substantially linearly through a rotational center of the transmission wheel. First and second detection patterns contact the contact point spring during rotation of the transmission wheel to generate a rotational position detecting signal corresponding to a rotational position of the transmission wheel. The first and second detection patterns are disposed at an angle of substantially 180 degree relative to the rotational center of the transmission wheel.

A conventional type clock with a date, hour, minute and seconds display, characterized in that Maya signs are provided instead of the usual hour signs and in that the 20 Tzolkin day symbols are applied to an outer ring that can rotate according to the clock movement. The meaning of each of the respective combinations of Maya signs and Tzolkin day symbols can be inferred from the corresponding Tzolkin calendar.

A perpetual calendar device as set forth which continually maintains a display of the present month and day as well as the minimum birth year for an individual who is entitled to purchase alcohol or tobacco products. The displays of the birth year information can be switched back and forth between the alcohol birth year display and the tobacco birth year display as desired to prevent confusion by the clerk. The displays are identified. The device is adapted for use by store clerks and the like to check to determine whether an individual wishing to purchase these products has attained the minimum age required.
摘要:
An automatic electrical device having a rack superimposed on an ordinary calendars and having seven light emitting diodes (LED's) of a single color affixed thereon to indicate the current day of the week, and similarly thirty-seven LED's of a single different color to indicate the current day of the month. Operation of the device is based on an electrical impulse transmitted daily by a clock through a switching network to sequentially energize the LED's. A monthly programmed electrical impulse counter provides means for coordinating operation of the device with calendar changes in a new month. Means provided to adjust leap year variation which provides means to program continuous operation of the device in unlimited time.
摘要:
To provide an actuator which can achieve a reduction in size and weight of a device in which the actuator is mounted by amplifying and outputting displacement of a movable end of a vibrating plate as vibration in an in-plane direction, and to provide a timepiece and a notification device using the same, in an actuator (10), when a voltage is applied to a piezoelectric element (21) formed on a vibrating plate (12), the vibrating plate (12) generates bending vibrations in an out-of-plane direction, and one end portion (125) repeats displacement in an in-plane direction as a movable end. The displacement is transmitted to a lever (32) whose base end side (321) is connected to the end portion (125) of the vibrating plate (12) and an elastically deformable constricted portion (31), and a free end (322) of the lever (32) vibrates in the in-plane direction to drive a follower member (500).
摘要:
A postage metering system includes a device to monitor the passage of a unit of time, a calendar profile, a system date and a control system. The calendar profile has parameterized data including day, month, year and leap year information so that dates may be reconciled. The control system is for advancing the system date depending upon the information contained with the calendar profile and the passage of a given amount of time.
摘要:
The electronic watch includes hands (2, 4, 5) indicating the time, a device (6) displaying at least the date, this device being formed of first (9) and second (10) indicators on which are marked figures (11, 12) respectively indicating the tens and the units of said date. A control member able to be activated manually allows the hands to be set to the correct time and the date to be set. The first (9) and second (10) indicators are each driven by an independent motor (17, 18).
摘要:
An electronic timepiece has a calendar advancement device resistant to external shock and capable of achieving date correction in a short time. A date dial advancement transducer (51) is activated in response to a date dial drive signal generated by a 24-hour switch. A date advancement mechanism (a date gear train) (52) employs a Geneva wheel for stabilizing the date dial (70). A bounding restraint lever is regulated using an eccentric cam or the like provided coaxially with the Geneva wheel.
