Title: Method for controlling direct injection of fuel into combustion chamber of internal combustion engine
Inventor: POGGIO LUCA
IPC: F02D45/00
Filed: 1999-11-26
Abstract: PROBLEM TO BE SOLVED: To provide a method for controlling a fuel injector of an internal combustion engine capable of accurately determining discharge time interval at which a desired amount of fuel is supplied. SOLUTION: An amount of fuel to be injected is calculated, starting from a first dead center, and a pressure existing in an intake manifold at the first dead center is evaluated in a second stroke of a cylinder preceding the first dead center (51). An injection advance angle is evaluated based on the evaluation of the pressure (52), and a pressure in a fuel manifold is detected (54).  An average pressure existing in a combustion chamber during injection is evaluated based on the evaluation of the pressure and the injection advance angle and a function representing a process of changes of pressure in the combustion chamber under reference operation conditions of an internal combustion engine (53, 55, 56, 57, 58, 59, 60), and an average flow rate of a fuel injector during a period of injection is evaluated based on a difference between the average pressure and the pressure detected in the fuel manifold (61). Discharge time interval of the fuel injector is calculated based on the evaluated average flow rate and a calculated amount of fuel and is taken into a program.

Title: Electrifier and image forming device
Inventor: OTSUKA KEIZO
IPC: G03G15/02
Filed: 1998-11-11
Abstract: PROBLEM TO BE SOLVED: To always carry out satisfactory electrification irrespective of the use conditions of a body to be electrified and an electrifying member by controlling, based on a temperature detected by a temperature detection means, the intervals of cleaning the surface of the contact electrifying member by a cleaning member. SOLUTION: As an external temperature decreases, the value of the resistance of an electrifying roller 2 increases. When the value of the resistance of the electrifying roller 2 increases, an AC current required for uniform electrification becomes large, resulting in an increase in amount of abrasion of a photoreceptor 1 and hence a decrease in the life of it. To counteract this in the case of from the first sheet to up to the 10000-th sheet, the electrifying roller 2 is cleaned at intervals of one time per 1000 sheets at 5 deg.C or below, at intervals of one time per 800 sheets at 5 to 15 deg.C, and at intervals of one time per 700 sheets at 15 to 20 deg.C. It is cleaned at intervals of one time per 500 sheets at >=20 deg.C or above or after 10000 sheets.  By controlling the cleaning-timing intervals of a cleaning member 4 in such a manner, an irregularity in electrification is prevented in all environments, also an amount of abrasion of the photoreceptor 1 is decreased, and its life is, therefore, prolonged.
