摘要： A secondary battery with high safety is provided. A heater and a diode are connected in series, and a thermistor is connected in parallel with thus formed series circuit. A fuse is connected in series with thus formed parallel circuit to form a protective circuit, which is attached to an accumulator to complete a secondary battery. In the case of overcharging, the accumulator generates heat so that the thermistor heats up to increase the resistance value. As a result, the current pass through the heater, which generates heat to break the fuse. In the case of short circuit, the diode is reverse-biased and no current passes through the heater so that the fuse does not break.

摘要： A protective circuit for a secondary battery is formed with a heater and a thermistor that are connected in parallel, and a main fuse is connected in series with the parallel circuit. In a secondary battery equipped with this protective circuit, a charging/discharging current passes through the protective circuit and is limited by the operation of the thermistor when the voltage applied during abnormal conditions is relatively low. On the other hand, the current will cause the main fuse to blow when the voltage during abnormal conditions is high.

摘要： An electrostatic latent image is formed by the Carlson process, etc. on a base (photosensitive body) to develop the electrostatic latent image by a solidification developer in which coloring agent particles are dispersed into a dispersion medium in a solid state at an ordinary temperature and adapted to reversibly repeat fusion by heating at about 30.degree. C. at a temperature above a melting point and solidification by cooling, thus to form a developer picture. Thereafter, the base and a transferred body are caused to be subjected to pressure-contact and heating process to fuse the dispersion medium at a pressure-contact and heating temperature more than the melting point of the dispersion medium to subsequently cool the dispersion medium down to a temperature less than the melting point to peel the transferred body to transfer the developer picture onto the transferred body. Alternatively, the dispersion medium is softened at a pressure-contact and heating temperature set so that this temperature falls within a range where it is not above the melting point to subsequently peel the transferred body to transfer the developer picture onto the transferred body. On the surface of a recording paper, a resin layer compatible with a dispersion medium of a developer may be formed.
