The decrease in the saturation magnetization quantity and further, the traveling defect, etc., of the magnetic recording medium by the corrosion product are resulted. The raw sheet provided with the thin ferromagnetic metallic film is cut arbitrarily in its transverse direction and is taken up in the cut state. The thin ferromagnetic metallic film is subjected to an oxidation treatment and the corrosion resistance in the high-temp. high-moisture atmosphere is improved if such sheets are stored in the oxidative atmosphere.

Title: Dc power-supply device
Inventor: ONO MAKOTO
IPC: H02M7/06
Filed: 1989-11-15
Abstract: PURPOSE:To obtain a simple DC power supply which hardly malfunctions in such a power supply that operates for two sorts of AC input voltage by controlling a double-throw thyristor, to automatically switch a full-wave rectifier circuit and a voltage-doubler rectifier circuit. CONSTITUTION:The voltage of capacitors 13, 14 is compared with the voltage of the Zener diode 23 of a detecting circuit. When AC input voltage is low, then a transistor(Tr) 24 is turned OFF, and the Tr 25 of a hysteresis circuit is turned ON, and the thresh level of the detecting circuit is heightened. Besides, driving Tr 26, 27 are also turned ON, and a double-throw thyristor 15 is forced to be turned ON. In other words, a rectifying/smoothing circuit is turned into a voltage-doubler rectifier circuit. In the meantime, the AC input voltage is turned high, and when the Zener diode 23 of the detecting circuit is turned ON, then the Tr 25, 26, 27 are turned OFF. Accordingly, the thresh level is lowered, and the double-throw thyristor 15 is turned OFF, and so the rectifying/ smoothing circuit is turned into a full-wave rectifier circuit.
