The present invention has an object to provide an image forming apparatus and method which enables an operator to easily adjust to the desired printing density. A paper feeding roller is driven in timing along with a registration roller. The irradiation of a modulated laser beam is started, a developing high-voltage is changed from "0" V to a predetermined voltage V1, and the voltage is changed to V2 at other timings. By sequentially changing the voltage in this manner, the printing densities from laser modulating data d1 to d10 are adjusted and printing in different densities can be performed.

An anisotropically electroconductive adhesive which is solid at room temperature, preferably, in the form of a film is prepared by dispersing conductive particles such as metal particles and the like in a thermoplastic insulating adhesive composition comprising an unvulcanized thermoplastic elastomer such as a styrene-based elastomer and a crosslinked synthetic rubber and/or thermoplastic elastomer as a vulcanizate derived from an unvulcanized synthetic rubber or thermoplastic elastomer using a vulcanizing agent such as organic peroxides. The conductive adhesive is useful in adhesively bonding, for example, two electronic circuit boards without disadvantages of instability of the electric resistance, inconvenience in the application and so on.

摘要:
An engine controller performs low opening degree control during a first intake stroke period since an engine start is commenced until first intake strokes of respective cylinders end. Thus, an opening degree of an intake throttle valve is controlled to a fully closed position or proximity of the fully closed position such that intake pressure downstream of the intake throttle valve becomes equal to or lower than critical pressure with respect to intake pressure upstream of the intake throttle valve during an intake stroke of each cylinder. The controller calculates a leak air quantity at the time when the intake throttle valve is fully closed based on an intake air quantity sensed during the low opening degree control. The controller corrects a feedback gain of idle speed control in accordance with the leak air quantity of the intake throttle valve.
摘要:
An intake throttle valve is located in an intake passage upstream of first and second intake ports, such that intake air flows into mainly the first intake port to generate a swirl flow when an opening degree of the intake throttle valve is not larger than a predetermined value, and flows into both the first and second intake ports when the opening degree thereof is larger than the predetermined value. Furthermore, first and second fuel injection valves for respectively injecting fuel to the first and second intake ports are controlled to inject fuel from the first fuel injection valve when the opening degree of the intake throttle valve is not larger than about the predetermined value, and to inject fuel from both the first fuel injection valve and the second fuel injection valve when the opening degree of the intake throttle valve is larger than about the predetermined value.
摘要:
An intake pressure sensor is provided in an intake manifold of a first cylinder. During steady operation, intake quantities of respective cylinders are sensed with an airflow meter provided in an intake pipe of an engine, and the intake quantity of the first cylinder is compared with the intake quantities of the other cylinders to obtain intake pressure variation correction coefficients of the other cylinders. Also, average intake pressure of the first cylinder is corrected with the intake pressure variation correction coefficients to calculate average intake pressures of the other cylinders. During transient operation, estimation intake pressure is anticipated from a target opening degree of an intake throttle valve with the use of a physics model. Intake quantities of the respective cylinders are calculated with the use of the estimation intake pressure and the intake pressure variation correction coefficients.

摘要:
A fuel injector for an internal combustion engine which has a spray hole designed geometrically to produce a spray of fuel so that substantially 70% or more of an amount of the spray hits a preselected area of a head of an intake valve of the engine when the intake valve is closed. The preselected area is one of a first and a second area of the intake valve head which are defined by a reference boundary line extending through a base end of a stem of the intake valve. The preselected area is the first area closer to an intake manifold, while the second area is closer to an exhaust valve. This avoids rich misfire and reduces HC emissions from the engine regardless of the intake valve is in a closed state or in an open state.
