IPC: H02J7/04
Filed: 1998-04-07
Abstract: PROBLEM TO BE SOLVED: To make a proper electric charging neither too much nor too little by providing a first process constituted of a first stage charging a battery to the prescribed voltage at a constant charging current and a second stage charging the battery to the prescribed voltage at a lower constant charging current and a second process charging the battery at a further lower charging current, and setting the charging time of the second process based on the charged electrical quantity of the first process. SOLUTION: A constant current charge at 0.2 CA is made in a first stage of a first process, for example. When the terminal voltage detection value becomes 2.4 V/cell, the current is lowered to 0.05 CA, and a constant current charge is made. When the terminal voltage detection value becomes 2.4 V/cell, a second stage is completed, and a second process is started. A constant current charge at 0.05 CA is made in the second process, and the second process is completed when the prescribed electrical quantity is charged.  The electrical quantity Q1 charged in the first process is subtracted from the proper charged electrical quantity obtained by multiplying the discharged electricity quantity Qd, before a charge and the charging efficiency factor Ce together to determine the charged electricity quantity Q2 required for the second process, and Q2 is divided by 0.05 CA to obtain the charging time.

Abstract: PURPOSE:To permit the measurement of the input/output characteristics of even an encoder to be measured, to which a DC input cannot be applied, by a method wherein the input characteristics of the encoder are measured by applying a known discontinuous input waveform thereto such as a step waveform or the like. CONSTITUTION:From a waveform generator 13, a discontinuous analog signal x(t) whose amplitude is controlled by a result-processing circuit 15 is generated, and inputted to an encoder 10 to be measured. Thereupon, a band-pass filter 11 in said encoder 10 generates a known transient phenomenon waveform signal y(t) according to the transfer function thereof, which is digital-coded in an encoder 12 and stored in a memory 14. Then, said signal is processed in the result-processing circuit 15, being made to correspond to the analog levels corresponding to the sampling points of the waveform y(t) previously stored. Thereby, it is possible to measure the input/output characteristics of the encoder to be measured, to which a DC input cannot be applied.

Abstract: PURPOSE:To eliminate an error as to a clocking information signal by an oscillator with temperature compensation for an electronic timepiece, by keeping constant the mean frequency of the output signal of the oscillator, equipped with two oscillating circuits differing in temperature-frequency characteristic, without reference to temperature. CONSTITUTION:Output signal P1 of the 1st oscillating circuit 1 and output signal P2 of the 2nd oscillating circuit 2 are both rectangular waves and their frequency- temperature characteristics are represented as f1 and f2. Those signals P1 and P2 are sent to phase-shift detecting circuit 3, whose output signal P3 is divided by (n) at frequency-dividing circuit 4 to obtain signal P4, thereby actuating alpha timer 6. Then, signal P5 is a signal expressing the time when timer 6 counts P3, signal P6 expresses time beta generated by a beta timer, and signal P7 is generated slow-speed deciding circuit 5 to expresses f1<f2 or f1>f2. From signal P7, signal changeover circuit 8 judges whether either of f1 and f2 should be used as a frequency to be corrected while correcting the time determined by signals P5 and P6. Thus, an error as to a clocking information signal is eliminated.
