The paper feed rollers are formed into a semicircular shape and the energizing m...

An image forming apparatus having therein an image forming apparatus body and at least one post-processing apparatus, wherein there is provided an intermediate conveyance unit which is connected with and located between the image forming apparatus body and the post-processing apparatus and which has a sheet feed-in section that feeds in sheets ejected from the image forming apparatus body one by one at the same speed as the sheet ejection linear speed of the image forming apparatus body, a sheet...

An image forming system includes: a first and second stacking sections arranged at a position different from each other for stacking a sheet with an image formed thereon by an image forming section; a first conveyance path and a second conveyance path longer than the first one for conveying the sheet to the first and second stacking sections, respectively through a common conveyance path, wherein an interval between sheets fed along the common conveyance path is smaller than the difference betwe...

A combustion fault detection apparatus for an internal combustion engine, in which a cylinder signal is generated when the piston in each cylinder of the engine is located at a predetermined position, a time interval between cylinder signal is determined, and time intervals for respective cylinders are compared and computed thereby to detect when a combustion fault, if any, has occurred in a specific cylinder.

A control unit has a fuel supply controller and a throttle valve opening degree controller. The fuel supply amount controller estimates and calculates the amount of fuel being supplied in cylinders with a real time. The throttle valve opening degree controller calculates a necessary opening degree so as to give a predetermined air-fuel ratio in accordance with a result value by the fuel supply amount controller. The fuel supply amount controller has a processing in which a fuel supply amount is ...

An estimating execution for an inner surface portion adhesion fuel amount is practiced distinctlly and independently to an execution processing for a basic fuel injection amount. A correction coefficient to be multiplied by the basic fuel injection amount is calculated in accordance with the estimation execution for the inner wall surface portion adhesion fuel amount. The correction coefficient is multiplied by the basic fuel injection amount. Since the fuel injection amount is corrected in acco...

A clamshell-type copying machine for reproducing an image of a document. The copy machine has a body flame consisting of an upper half body, a lower half body, and a hinge-like connector of these half bodies. There are provided a first urging member, located in a vicinity of the opening, and a second urging member, located in a vicinity of the connector. Both of these urging member urge the upper half body and the lower half body to be separated from each other in which an urging force of the se...

An internal combustion engine control apparatus in which upon detection of transient state of the engine such as acceleration, deceleration or the like, the amount of fuel supply to the engine is corrected by using transient correcting coefficients which are determined previously and updated through learning procedure. The correcting coefficient is updated on the basis of the result of comparison of the air-fuel ratio detected upon occurrance of the transient state with a predetermined reference...
