Title: Combined electronic timepieces and chronographs
IPC: G04F10/00
Filed: 1975-11-20
Abstract: 1494293 Electronic timepieces SUWA SEIKOSHA KK 20 Nov 1975 [25 Nov 1974]  47820/75 Heading G3T An electronic stop watch has a control circuit as Fig. 1 controlled by signals from a manual control means, the circuit providing outputs commanding measurement, (by means not shown), of a desired number of lap times within an elapsed time period and commanding indication on an indicator (not shown) of both the lap times and the overall elapsed time. One manual control means produces pulses S/S Figs. 1, 2 calling for the starting and stopping of time measurement; a first pulse S/S clocks a flipflop 11 which produces a corresponding command signal CE to start a time measuring means and passing time is indicated. The other manual control means produces, via a shaping circuit (not shown), pulses L/R calling for an indication of a lap time and release of lap time indication. When the first pulse L/R is produced a master flip-flop 12 of a master/slave flip-flop pair 12, 13, produces a high level command signal LAP to cause indication of a first lap-time and the contents of the measuring means, i.e. the first lap time, are stored in a memory (not shown). At the next pulse L/R the signal LAP is switched to low level whereupon the lap time indication is released and the content of the memory changes with passing time measured, an indication of the running total elapsed time being given. The lap time indicating operation may be repeated a number of times until a second pulse S/S is applied, whereupon measurement of time ceases, the time indicated at that instant being total elapsed time. A NAND circuit 1 provides, via an inverter delay circuit 2, a reset signal RC for the measuring and indicating circuits, only when L/R is at high level and is applied when signal CE and a signal M from slave flip-flop 13 are at high level. The signal M prevents delivery of a reset signal RC at the moment when the lap time indicated is released and the condition CE = 1 exists. As described with reference to Fig. 3 (not shown), if measurement is stopped during indication of lap time, the indication is maintained; the total elapsed time is not indicated until lap time indication is released.

As shown each logic gate comprises a pair of Josephson devices, but a single such device for each gate may be used if ground plane connections are provided. The logic circuit is operated by three phase pulses # 1 , # 2 , # 3 . In the first "set up" phase # 1 , Josephson device Jl is switched to its finite voltage state by control current in a line 24 and the gate current I 0  from generator 21 is directed wholly through inductor L2. Device J then relapses to its zero voltage state but the diverted current continues to pass through the shunt inductor. In the second "data in" phase # 2  a change of gate current I 0  is produced if a logic input is applied in this period, this change being almost wholly passed through the series circuit path 20 as a negative current. Gate current is applied at this time to Josephson device J SENSE, and if current is present in the series path 20 the device is switched to its finite voltage state to provide an appropriate output. In the third "reset" phase # 3  control current is again applied to device J1 which switches to its voltage state to extinguish any circulating current in the sensing circuit. At the same time the gate current I 0  ceases and any switched logic gate is reset.
