摘要:
A system for controlling engine speed for a vehicle such as a fork-lift. The system has an accelerator pedal for controlling an engine speed, and a control lever for controlling the direction of movement of the vehicle, or the system is provided with a seesaw type accelerator pedal for controlling the engine speed and the direction of movement of the vehicle.An EXNOR gate is provided for detecting deceleration of the engine while the accelerator pedal is depressed. When deceleration is detected, the throttle valve is returned to an engine idling position or the supply of fuel is cut. Thus, an effective engine braking can be obtained when the direction of movement of the vehicle is changed while the accelerator pedal is depressed.A window comparator is provided for detecting the area near the end of deceleration, so that the engine speed is increased prior to the commencement of acceleration.

A control device for use in a cargo handling vehicle in which a single power plant provides both the vehicle drive and the power to the cargo handling device has a continuously variable transmission. The cargo handling device is actuated by means of a hydraulic pump. Whether or not the cargo handling device is in operation the operator need not adjust the degree of depression of a drive pedal to maintain constant vehicle speed because automatic compensation means are provided for that purpose. The demands upon the vehicle operator are accordingly reduced.

This invention relates to a cargo-handling vehicle equipped with a cargo-handling apparatus and having a single power plant adapted to commonly drive a hydraulic pump for driving and a hydraulic pump for cargo-handling. A driving command signal in the form of an analog or digital electric signal output from a driving operation device in response to the operated amount thereof is output to first conversion means. The first conversion means converts the driving command signal or the operated amount of the driving operation device to power plant revolution data for driving which is determined by the preset function, and then outputs the data to selection means. A cargo-handling command signal in the form of an analog or digital electric signal output from a cargo-handling operation device in response to the operated amount thereof is output to second conversion means. The second conversion means converts the cargo-handling command signal or the operated amount of the cargo-handling operation device to power plant revolution data for cargo-handling which is determined by the preset function, and then outputs the data to the selection means. The selection means selects at least one of the data and then outputs the selected data to control means for regulating the speed of the power plant. The control means regulates the power plant speed in accordance with the input data.

Disclosed is a sensor for detecting flow quantity of fuel supplied to a fuel injection system based on an idea that the flow quantity of fuel supplied to a fuel injection system is detected by means of detection of a displacement of a spill-ring. This sensor is provided with a detection member connected with a spill-ring of a fuel injection system, a coil assembly consisting of a coil for detecting the displacement of the spill-ring which is fitted to one end of a bobbin which is arranged to face with the detection member but not to contact the detection member, the one end of the bobbin being arranged to face with the detection member, and a coil for temperature compensation, the two coils being arranged side by side along the bobbin with a predetermined space therebetween, and a member for holding the coil assembly and for fitting the coil assembly to the fuel injection system.

In a sealing or piston cup for maintaining lubricating oil on a sealing surface, the sealing surface thereof is formed with a circumferentially extending angular recess or groove which functions to retain lubricating oil. The sealing cup with the recess can ensure a smooth and stable operation of the device.

A sealing cup to be used for a hydraulic piston-cylinder device the cup having an outer lip with a leading edge adapted to slide along a wall when fitted in the device. The angle .alpha. of the leading edge with respect to the cylinder axis is made smaller than the angle of a portion other than the leading edge with respect thereto, and is made as 1.degree..ltoreq..alpha..ltoreq.15.degree. in the free condition of the cup. When the sealing cup is installed to be slid in the cylinder, a wedge-shaped clearance is formed between the leading edge and the cylinder wall due to provision of the angle .alpha., thereby admitting the fluid therein to decrease the slide resistance of the sealing cup.

An image forming apparatus includes a transfer member that retains developer; a housing provided with a removing member that removes the developer and having an intake opening that is opposed to the transfer member, the developer removed by the removing member being taken into the housing through the intake opening; a guiding pipe connected to the housing and having a suction hole through which the developer is sucked and an outlet through which the developer is discharged; and a suction member that applies a suction force to an inner space of the housing through the guiding pipe. A capturing area for capturing the developer that flows through a flow channel from the suction hole to the outlet is provided in the flow channel. A cross section of the capturing area in a radial direction of the flow channel is larger than that of other areas.

A developer collecting device includes a housing provided with an opening opposed to a developer carrying member, a collecting member provided on a support member and capable of coming into contact with and separating from the developer carrying member, a suction path provided between the opening and a suction member for sucking developer removed from the developer carrying member, an opening-closing plate that opens or closes the suction path, an urging member that urges the opening-closing plate, a retaining member that retains the opening-closing plate, and an opening-closing unit including a rotating member and an elastic member whose ends are connected to the rotating member and the support member. The elastic member is pulled so as to rotate the rotating member in association with a movement of the collecting member, thereby rotating the opening-closing plate so as to open or close the suction path.
