Abstract: PURPOSE: To prevent the output drop due to the increase of alcohol concentration in the mixed fuel by a method wherein there is provided a control unit to increase the compression ratio in a combustion chamber in the case that the alcohol concentration in the mixed fuel exceeds the set point, in the captioned engine using gasohol as fuel.  
     CONSTITUTION: There is provided the control unit 19 consists of a comparator 21, a transistor 22 and the like to increase the compression ratio in the combustion chamber 5 in the case that the alcohol cncentration in the mixed fuel exceeds the set point, in the variable compression ratio engine using gasohol as fuel. When the alcohol concentration is above the set point, the output is produced from an alcohol concentration sensor 18 to actuate the comparator 21 to emit the output signal. The output signal turns the transistor 22 ON to operate a servo-motor 15 to move a variable piston 12 to its lowermost position in a cavity 11. The volume within the combustion chamber 5 is reduced by the displaced volume due to the movement of the variable piston 12, and consequently the compression ratio is heightened and the burning velocity is increased to compensate the output shortage at the high alcohol concentration state.

Abstract: PURPOSE:To specify the electrostatic charge amount of the surface of a photosensitive drum without reference to fluctuations of temperature by providing shape memory alloy near the photosensitive drum surface at specific temperature, and coupling it with an electric material in series through a volume shaft. CONSTITUTION:The shape memory alloy 1 stored with a shape by being contracted in a coil shape at the specific temperature is coupled with the elastic material 3 in series through the volume shaft 2 of a charger transformer. Then, this alloy is arranged near the surface of the photosensitive drum 4.
