The electrode members 10 contain at least one type of element selected from Ti, Hf, Zr, V, Nb, Mo, W, Sr, Ba, B, Th, Al, Y, Mg, In, Ca, Sc, Ga, Ge, Ag, Rh, Ta, and rare earth elements (other than Y and Sc) in a total amount in the range of 0.01 to 5.0 percent by mass, and the balance composed of a Fe—Ni alloy and impurities. Since the alloy constituting the electrode members 10 contains a Fe—Ni alloy as a major component, the alloy has a thermal expansion coefficient close to that of glass and is excellent in plastic formability. Since the alloy constituting the electrode members 10 contains a specific additional element, the alloy is excellent in sputtering resistance and a discharge property.

When a horizontal skipping operation is performed in a solid-state imaging apparatus that includes an A/D converting circuit in each column and that applies an arithmetic operation process to a digitalized signal and an arithmetic operation is performed with signals held by a plurality of register circuits, A/D converters and register circuits in columns in which signals are skipped, or not read out, are not involved in the operations. A more consideration is needed in terms of the use efficiency of circuits. A unit for connecting a register circuit of a certain column and a register circuit of a different column is arranged.

A cold-cathode fluorescent lamp having high brightness with long life and an electrode for this lamp are offered. The electrode comprises a base and a covering layer that covers the surface of the base. The base is formed of one metal selected from nickel, a nickel alloy, iron, and an iron alloy. Consequently, a base having a shape, such as a cup, can be easily produced. The covering layer comprises (a) a surface layer made of tungsten or molybdenum and (b) a bonding layer that is made of zinc alloy and that is placed between the base and the surface layer. In comparison with nickel and iron, tungsten and molybdenum are resistant to sputtering, have a small work function, and have a high melting point. The presence of the bonding layer enables sufficient bonding between the surface layer and base. A cold-cathode fluorescent lamp provided with the foregoing electrode can suppress the reduction in brightness and the consumption of the electrode. Therefore, it has high brightness and long life.

The present invention is relative to a battery capacity calculating method including a reference discharge curve calculating step of finding a discharge curve, operating as a reference, a corrected voltage calculating step of correcting a measured voltage V1 of the battery with a component of an electrical resistance to find a corrected voltage V, and a capacity calculating step of finding the discharging capacity of the battery from the discharge curve, operating as a reference, using the corrected voltage V. The capacity calculating step includes a sub-step of calculating a capacity deterioration index S, as a ratio of capacity decrease caused by battery deterioration. The discharging capacity, calculated from the discharging capacity, operating as a reference, using the corrected voltage V, is further multiplied with the capacity deterioration index S to calculate the discharging capacity.

A solenoid type switch has at least two driving coils. The driving coils turn off a switch with a current for example an overcurrent that flows in the switch. The driving coils are magnetized or demagnetized by a driving circuit so as to turn on or off the switch. The driving circuit magnetizes or demagnetizes the driving coils in accordance with a control signal supplied from a controlling circuit. Thus, the switch can be turned off with the current that flows in the driving coils.

A commercially available power source is rectified by a diode bridge and a capacitor and supplied to a transformer via a terminal. One end of a primary coil is connected to the terminal and the other end is connected to a switching device. One end of a feedback coil is connected to the switching device and the other end is connected to the terminal. A negative feedback circuit is provided between the switching device and the terminal. A rectifying circuit comprising a diode and a capacitor is provided on a secondary coil. A node of the coil and the capacitor is connected to the terminal via a resistor. In detecting circuits, a voltage across the terminal is detected and a current across the resistor is detected. When the detected voltage and current are equal to predetermined values, a control signal is supplied to a feedback circuit.
