Title: Electrophotographic developer
Inventor: MAKABE AKIRA
IPC: G03G9/08
Filed: 1993-09-08
Abstract: PURPOSE:To prevent fogging due to unstable electrostatic charge of a toner and to enable high quality development with no stain of a background by adding electron withdrawing groups as chemical groups forming the surface of the toner. CONSTITUTION:When an electrophotographic developer is obtd. by mixing a magnetic carrier with a negatively chargeable toner 1, electron withdrawing groups are added as chemical groups forming the surface of the toner 1 so as to modify the surface of the toner 1. By the addition of chloride ion groups -Cl as the electron withdrawing groups, the toner 1 becomes liable to attract electric charges and is easily negatively charged. Nitro groups or halogen groups may be used as the electron withdrawing groups. The stain (fogging) of the background of a developed part can be prevented by negatively charging the negatively chargeable toner 1 in a proper manner.

IPC: F02D45/00
Filed: 1987-09-08
Abstract: PURPOSE:To reduce vibration of an engine body without deteriorating responsibility in acceleration and deceleration by reducing fluctuating component of torque through controlling loading torque absorbed by auxiliary machines in correspondence to fluctuating component of torque generated by an internal combustion engine. CONSTITUTION:Revolutional acceleration and revolution speed of the crank shaft at respective turning angles are varied in every moment with fluctuation of torque generated by an internal combustion engine 1 and when output pulse from a crankangle sensor is output in a frequency modulated, form the higher is frequency the higher becomes voltage and the lower is frequency the lower becomes voltage.
