IPC: G03G15/08
Filed: 1990-05-24
Abstract: PURPOSE:To prevent the occurrence of surface fogging caused by faulty bias by allowing a developer carrying member to have an electret dielectric layer and forming it so that the thickness of the electret layer may be <=2mm.

Title: Engine fuel control device
Inventor: KAKO HAJIME
IPC: F02D41/00
Filed: 1988-05-30
Abstract: PURPOSE:To avoid obstacle in the running of an engine even when a fuel cut is performed by stopping fuel injection according to the number of an output signal of a pressure detector which detects inlet pipe pressure and to a decided pressure value based on an air pressure value. CONSTITUTION:In a control device 11, an output value of a pressure sensor 9 obtained is set as an air pressure value when a value of throttle divergence which is detected by a throttle divergence sensor 10 is the same as a threshold value or more. And a decided pressure value is computed based on the air pressure value. At this time, if a pressure value in an inlet pipe which is detected by the pressure sensor 10 is less than the decided pressure value, then pulse length as the amount of fuel injection from an injector 7 is set as 0, as decision for fuel cut is made. Thereby, the amounts of a decided pressure value and pressure in an inlet pipe altered according to air pressure have nothing to do with the air pressure, thus the fuel cut can be executed irrespective of the air pressure. Hence, various troubles related to driving such as an engine stall or a reduction in speed of an engine 1 can be avoided.
