摘要:
An image forming apparatus including an image transport member driven to rotate with a latent image formed on a surface thereof, and a toner transport member driven to rotate with toner attached thereto for developing the latent image and in contact with the image transport member to transport the toner to the image transport member. The image forming apparatus further includes a toner layer thickness regulating member disposed in pressure contact with the surface of the toner transport member to regulate the thickness of a layer of toner transported in a state of being attached to the surface of the toner transport member. The amount of charge of the toner on the surface of the toner transport member is regulated in the range of from -16 .mu.C/g to -19 .mu.C/g.

An image transferring apparatus is provided which holds a print sheet in a nip between an image carrier and a transfer roller and supplies the current to the transfer roller to transfer a toner image formed on the image carrier to the print medium. The apparatus has conductive brushes disposed in contact with ends. of the transfer roller to form a bypass circuit. The bypass circuit is connected to ground through a resistor and introduce the part of the current supplied to the transfer roller in an image transferring operation, thereby avoiding formation of any print defects such as discharge-caused marks or toner stops.

摘要:
An object is to prevent deterioration in both exhaust emission and fuel efficiency by suitably combining OTP boosting with power boosting. An electronic control unit (ECU) 30 of the present invention is arranged to control a fuel injection amount of an injector 7 to an engine 1 according to an operating condition of the engine 1, and perform OTP boosting of the fuel injection amount to prevent overheating of a discharge passage 3 and a catalyst converter 11 when the engine 1 comes into a high load and high rotation operating condition and perform power boosting that increases the fuel injection amount to enrich an air-fuel ratio to an output air-fuel ratio when the engine 1 comes into a high load operating condition. The ECU 30 executes the power boosting when the engine 1 comes into the high load and high rotation operating condition and executes the OTP boosting later from the start of the power boosting, delayed by a period attributable to at least an increased amount of fuel by the power boosting.
摘要:
A harness installation structure includes a link arm that pivotally supports a movable body to a fixed body, a wire harness that is installed to extend from the fixed body to the movable body along the link arm. The wire harness is fixed without looseness at a region between one end of the link arm and the movable body. The wire harness is installed to extend in a bendable manner from the other end of the link arm to the fixed body. While the movable body is moved between an opened position and a closed position, a surplus length of the wire harness is produced at other portion of the wire harness than a movable body-side portion of the wire harness, and the surplus length is absorbed by bending the wire harness.
摘要:
In a laser beam machine comprising: a laser oscillator for generating a laser beam; a machining head for applying the laser beam, as a light spot, to a workpiece mounted on a machining table; and a control unit for controlling the movement of the machining table in an X-Y plane, the laser beam is kept inclined with respect to the workpiece in the machining direction, whereby, when the machining speed is increased, the sticking of dross to the workpiece is suppressed, and the machining speed can be increased accordingly.
摘要:
In an internal combustion engine, a base fuel amount is calculated, and an air-fuel ratio deviation for each region is determined by a predetermined engine operating parameter when the engine is in a transient state such as an acceleration state or a deceleration state. A transient fuel correction amount is calculated in accordance with the calculated air-fuel ratio deviation for each region determined by the predetermined engine operating parameter. A fuel amount to be supplied to the engine is calculated by correcting said base fuel amount in accordance with the transient fuel correction amount.
摘要:
A method for controlling the air-fuel ratio in an internal combustion engine in which the correction value of a transient fuel injection amount is decided, at a predetermined interval, in accordance with the acceleration or deceleration state of the engine, and the amount of fuel injection supplied to the engine is corrected by the decided correction value. In the process of the correction, the deviation of the air-fuel ratio from a reference air-fuel ratio in acceleration or deceleration of the engine is detected, and the correction value of the fuel injection amount correction in the transient state of the engine in accordance with the detected air-fuel ratio deviation is determined. In the correction of amount of fuel injection in the transient state of the engine, the correction value is decided on the basis of a factor for deciding the correction value and the blunted value of the factor for deciding the correction value.
摘要:
The time when the startup of an engine is completed is detected. In accordance with the coolant temperature of the engine directly after the completion of startup, a correction coefficient is first determined, and thereafter, is gradually attenuated. The ignition timing of the engine is corrected depending upon the correction coefficient.
