Title: Digital arithmetic control method
Inventor: AOTSU HIROAKI
IPC: G06F7/38
Filed: 1978-02-03
Abstract: PURPOSE: To improve arithmetic accuracy of arithmetic control which includes digital arithmetic causing a truncation error, by feeding a truncation error back to an input signal.  
     CONSTITUTION: For example, in case of the arithmetic unit of a primary lag unit performing integer arithmetic, deviation (ε 1 ) is obtained by inputting input value (x), output value (z) of the arithmetic stage preceding by one, and residual (Δx) at the division time of divider 10 to subtracter 20. By receiving (ε 1 ) as its input, subtracter 10 obtains quotient (ε 2 ) and truncates its residual. Residual (Δx') of divider 10 is therefore extracted by using multiplier 15 and subtracter 40 and stored temporarily in memory 31 before being used for the formation of a deviation at the next step. Then, quotient (ε 2 ) is inputted to adder 21 and added to the output of the stage preceding by one, and the sum is used for the formation of a deviation at the next step. An arithmetic error is therefore eliminated through this repetitive procedure.

Title: Timepiece provided with light-electric power transducer
Inventor: NAGOYA MITSURU
IPC: H02J7/35
Filed: 1983-01-25
Abstract: PURPOSE:To drive a timepiece provided with a light-electric power transducer without receiving the influence of an external environment by responding a light emitting means operating on a commercial power source to the alarm signal via a power generation timing counter for detecting charging deficiency controlled by a power generation time counter for detecting substantial charging. CONSTITUTION:When the external environment darkens and when a transistor 18 turns off on dropping of the voltage of a solar battery 6 for a light-electric power transducer, the output A of a voltage detecting circuit 10 inverts to a low level, and the clock through an AND circuit 14 is shut off. A power generation time counter 26 which detects substantial charging stops counting. Therefore the counter 26 does not generate a high level carrier signal Q1 and a counter 24 for detecting charging deficiency is not reset. The counter 24 generates a high level carrier signal after prescribed counting, and an LED34 of an alarm circuit 28 is lighted via an FF30, etc. A relay 38 is then excited by an alarm signal detecting circuit 44 of a light feed body 4 to light an illuminating lamp 49 operating on a commercial power source and to charge the battery 6. The timepiece is thus driven without receiving the influence of the external environment.
