Title: Thermal head driving method and circuit
Inventor: ISOZAKI SHINGO
IPC: B41J2/365
Filed: 1992-07-02
Abstract: PURPOSE:To constitute a thermal head printing device capable of controlling temperature without generating uneven printing by controlling electric current flowing in a heat generating resistor dependent on temperature condition of the thermal head. CONSTITUTION:When printing is being continued, temperature of a thermal head rises. At this time, resistance value of a thermistor 14 attached to the cassette of the thermal head decreases. Accordingly, gate voltage of an output driver B11 becomes small, electric current flowing in a heat generating resistor 15 decreases, and the temperature rise of the thermal head is restrained and cooled. On the contrary, when the temperature of the thermal head becomes lower, the resistance value of the thermistor 14 rises, so that the gate voltage of the output driver B11 becomes higher and the current flowing in the heat generating resistor 15 increases. Thus, the quantity of the current flowing in the heat generating resistor 15 is controlled in accordance with the temperature condition of the thermal head, so that heating value of the thermal head can be controlled even when a time for flowing the current to the heat generating resistor 15 is not changed.

Abstract: PURPOSE:To properly set air-fuel ratio in a transient condition by increasingly/ reducingly correcting the acceleration correcting number of times of fuel injection quantity which is increasingly corrected for acceleration, in accordance with an engine condition and engine speed based on a cooling water temperature. CONSTITUTION:In a control means 13, acceleration is detected from the quantity of change in throttle opening in a defined time detected by a throttle position sensor 8b. The correcting number of times of fuel injection quantity is retrieved in accordance with a cooling water temperature detected by a water temperature sensor 4, and the correction factor of engine speed is retrieved in accordance with engine speed detected by an engine speed sensor 3. After finishing the detection of acceleration, the correcting number of times of acceleration is calculated from the correcting number of times of fuel injection quantity and the correction factor of engine speed. Thereby, since the injecting number of times for an acceleration increasing quantity can be set, the dispersion of acceleration correcting terms can be prevented to properly keep an air-fuel ratio in accelerating operation.
