A digital watch system includes a crystal controlled oscillator with frequency division which controls a set of counters, each counter carrying coded horological data. Selected counter set data is multiplexed into a seven segment decoder. The decoder output is demultiplexed into memories, one for each of the segments in each of the display digits. The memories control segment drivers for the liquid crystal digital displays.

An electronic time-piece is advanced by electronic pulses which are generd by a fixed frequency signal source. In order to correct the indication of the time-piece, a circuit is provided for adding or deleting pulses to thereby increment or decrement the indication. One push-button switch is provided for both adding or subtracting seconds from the indication displayed by the time-piece. Each depression of the push-button adds one second to the indication. When the user depresses the push-button ...

A time counting control system comprises: a timing signal generator for generating at least a read-in clock signal on the basis of a reference clock signal outputted from a reference clock signal oscillator; a microprogram control unit including an address register which is controlled by the read-in clock signal outputted from the timing signal generator, an address section which decodes the contents of the address register and energizes address lines related to a plurality of processing steps, ...

A multi-position switch particularly adaptable for an electronic watch comprises a movable plate or disk mounted within a cup-like body and rotatable about an axis to different positions for accomplishing various setting or operating modes. Fixed contacts on the inside of the switch plate are spaced apart but electrically connected so that when the plate is rotated to certain positions relative to its central axis the contacts are aligned for engagement with a particular pair of a series of term...

An electronic timepiece adjustment circuit is provided for allowing adjustment of the division ratio of the divider circuit of an electronic timepiece by external switching circuitry. An electronic timepiece includes an oscillator circuit for producing a high frequency time standard signal and a divider circuit having an adjustable division ratio to produce a low frequency time standard signal in response to a high frequency time standard signal applied thereto. Adjustment circuitry is coupled t...

Zero adjustment of second information in an electronic timepiece is carried out upon receiving a command from the operator. "Increment one" is performed upon minute information when the second information is between 24 and 59 seconds when the zero adjustment command is generated. Minute information is not changed when the second information is between 0 and 23 seconds when the zero adjustment command is generated.

An electronic timepiece apparatus which comprises an electronic time-counting circuit including an oscillator generating standard clock pulses; time-setting means including an actuating switch for correcting the value of a count made by the electronic time-counting circuit; means for correcting the value of a count made by the electronic time-counting circuit for each prescribed period in accordance with the amount and direction of correction determined as the result of comparison by the time-se...

A switch control unit for an electronic timepiece comprises a plurality of control switches and a sequence decoding circuit which detects sequences of actuations of the control switches to provide a plurality of output signals in dependence on varying combinations of sequences of actuations of the control switches. In modified form, the switch control unit comprises a plurality of control switches, a detecting circuit to detect numbers of actuations of each of the control switches thereby to pro...

A drum-type washing machine having a self-balancing outer tub assembly is provided by which balance of the outer tub assembly is maintained while the drum is rotated, without the use of a separately installed counterbalance for the front part of the tub assembly. The outer tub assembly includes a front outer tub having an open front and rear; and a rear outer tub having a closed end and an open end coupled to the front outer tub. The front outer tub is formed of a material having a specific grav...

An electronic timepiece having a pulse generator producing a high frequency time standard signal, a divider circuit formed from a plurality of series-connected divider stages for producing low frequency timing signals in response to said time standard signal and a device for digitally displaying time in response to said timing signals, is provided with a correction circuit disposed in said divider circuit. The correction circuit allows a correction signal to be combined with a carry signal from ...
