Abstract: A battery capacity calculating method can very accurately calculate a residual capacity of a secondary battery especially in the last stage of discharging independently of environmental conditions such as a temperature or a deteriorated state. A battery capacity calculating apparatus (10) is equipped with a voltage measuring circuit (11) which measures the terminal voltage (Vmea) of a battery (1) at the time of discharging, a current measuring circuit (12) which measures the current value (I) of the battery (1) at the time of discharging, and a control circuit (13) which calculates a residual capacity and/or residual power. The operation unit (15) in the control circuit(13) calculates a discharged capacity (Qmea) and an apparent discharged capacity (Qocv) based on a terminal voltage (Vmea) and a current value (I) measured by the voltage measuring circuit (11) and the current measuring circuit (12), respectively, estimates a discharge curve (Cpre) in the future including the last stage of discharging based on a capacity shift ( DELTA Q) being the difference between the discharged capacity (Qmea) and the apparent discharged capacity (Qocv) during discharging, and calculates the residual capacity and/or the residual power of the battery (1) based on the estimated discharge curve (Cpre).

Abstract: A tape counter for counting an amount of tape by which a tape has run for a video signal recording and reproducing apparatus and method therefor, in which the number of frames on tape tracks over which each rotary head scans are counted according to a change in level of an envelope of a reproduced FM signal detected through each rotary head, the number of rotations of a rotary drum on which the rotary head is mounted is counted, and the amount of tape by which the tape has run is counted on the basis of the number of frames scanned by the rotary head and the number of rotations of the drum. The tape counter detects the amount of tape by which the tape has run in all running modes during a reproduction operation with a high accuracy and displays the amount of tape by which the tape has run in a series of units of hours, minutes, and seconds.

Abstract: A commercial power is rectified by a diode bridge and a capacitor and supplied via a terminal to a transformer. One side of the primary coil is connected to the terminal and the other side is connected to a switching element. One side of the feedback coil is connected to the switching element and the other side is connected to the terminal. Moreover, a negative-feedback circuit is provided between the switching element and the terminal. At the secondary coil, a rectification circuit consisting of a diode and a capacitor is provided. A connection point between the coil and the capacitor is connected via a resistor to the terminal. In a detection circuit, voltage is detected between the terminals and current is detected at both ends of the resistor. When the detected voltage and current are predetermined values, a control signal is supplied to the feedback circuit.
