A first estimated state of charge is output based on an estimated open voltage of a secondary battery. A second estimated state of charge is output based on the result obtained by integrating the measured current of the secondary battery and the upper limit of the error of the measured current and the capacity of the secondary battery. A third estimated state of charge is output based on the result obtained by integrating the measured current and the lower limit of the error of the measured current and the battery capacity. A fourth estimated state of charge is output based on the result obtained by integrating the measured current and the battery capacity. The fourth estimated state of charge is output as a state of charge within the period of the predetermined period.

State of charge computation system

The battery state-of-charge calculation device () is provided with a SOCV calculation unit () which outputs a first state of charge calculated based on voltage data, a SOCI calculation unit () which outputs a second state of charge calculated based on current data, an estimated impedance voltage calculation unit () which calculates an impedance voltage value based on an effective state of charge and the current data, a static determination unit () which determines that the impedance voltage value remains static for a predetermined time or longer in a range identified by a predetermined threshold value and outputs the determination result; and a SOC decision unit () which, based on the determination result, outputs the first state of charge as the effective state of charge where the impedance voltage value is static and outputs the second state of charge as the effective state of charge where the impedance voltage value is not static.

Objects are to reduce the burden on an operator and to improve fabrication efficiency. A transparent conductive film or a transparent optical film formed on a substrate W is irradiated with line illumination light by means of a line illumination device, line reflected light reflected at the transparent conductive film or the transparent optical film is detected with a camera, a color evaluation value of the detected reflected light is measured, and a film thickness corresponding to the measured color evaluation value is obtained using a film-thickness characteristic in which the color evaluation value is associated with the film thickness.

A camera includes a base section, and a grip section which is provided in at least one lateral end of the camera, bending to a rear side of the camera. The grip section is disposed with a slip-proof section adjacent to a zoom key which is longitudinally arranged. Additionally, a slip-proof section to prevent finger slipping is positioned on a back surface of the grip section.
