IPC: H02J7/04
Filed: 1987-06-19
Abstract: PURPOSE:To perform a charge while preventing an overcharge through a simple circuit constitution by using a gated controlling element in a part of a charging control circuit. CONSTITUTION:An AC power 2 is made to drop in voltage by a transformer 4 and thereafter rectified by a rectifier 6 to charge a battery 9 via a controlling element 7. When charging of said battery 9 is started in a state where a thermostat 11 is closed, the battery 9 is charged via a diode 19 because controlling elements 7, 8 are blocked. In this case, an electric current flows between the gate and cathode of said controlling element 7 so that the controlling element 7 is turned ON and the battery 9 is charged rapidly. When the battery 9 rises in temperature and the thermostat 11 is opened at the end of charging, a capacitor 13 is charged and the controlling element 7 is blocked. Even if the thermostat 11 is closed again in said state, the controlling element 8 is turned ON and a charging current is bypassed due to an electric current flowing from said capacitor 13 so that the controlling element 7 will not be turned ON again.

Title: Thermal head
Inventor: ARAI MASAJI
IPC: B41J2/35
Filed: 1977-12-20
Abstract: PURPOSE:To enable prevention of breakdown due to thermal runaway of a thermal head consisting of a heater having an intrinsic tendency to thermal runaway, by connecting a specified resistor with the heater in series. CONSTITUTION:Resistor 2 havng a resistance 0.5-1.5 times as high as that of heater 1 is connected with heater 1 in series and energized by pulse power source 3. When the resistance ratio of resistor 2 to heater 1 is greater than 1, and the resistance of heater 1 is becoming smaller than the initial value, power change is a nomotonous decrease from the initial set value; consequently, breakdown due to thermal runaway scarecely occurs. When the ratio is 1, even in the case of + or - 40% change in resistance of heater 1. the power consumption of heater 1 changes only by 6% at maximum, permitting image quality to change a little, and the best effect to be obtained.
