There is described an improved fuel door assembly. In one preferred embodiment, the fuel door comprises a housing that defines an axis of rotation and has a biasing element that is at least partially surrounded by a second interface that forms a cavity that narrows between the ends of the second interface. The fuel door has a first interface that contacts the second interface such that the biasing element urges the fuel door toward the closed position when the fuel door is at the closed position, and urges the fuel door toward the open position when the fuel door is at the open position.

A capacitance detecting proximity sensor forms a proximity detection range in a spatially open region, avoids the effects resulting from peripheral objects outside the detection target, and enables proximity detection with few malfunctions. The proximity sensor includes: a first detection electrode and a second detection electrode that are disposed to have a predetermined range difference h with respect to a detection direction Y in which a detection subject comes into proximity to the proximity sensor and are independent from a ground potential; and a proximity detection circuit that outputs, as a proximity detection output, the difference between a capacitance to ground Ca formed by the first detection electrode and a capacitance to ground Cb formed by the second detection electrode.

An automatic residual fuel vent device for a carburetor, the device including a fuel supply passage (15) connecting a fuel tank (TF) and a float chamber (10), a negative pressure passage (17) connecting an intake passage (8) and a negative pressure operating chamber (53) of a diaphragm pump (PD), a fuel vent passage (16) connecting the float chamber (10) and the fuel tank (TF), a single changeover cock (CO) provided so as to straddle the fuel supply passage (15) and the negative pressure passage (17), a negative pressure surge tank (TS) provided in the negative pressure passage (17), and the diaphragm pump (PD), which is connected to the fuel vent passage (16) and is operated by negative pressure of the negative pressure surge tank (TS), residual fuel of the float chamber (10) being returned to the fuel tank (TF) by the diaphragm pump (PD) operated by negative pressure from the negative pressure surge tank (TS) in accordance with the changing over of the changeover cock (CO). This enables residual fuel within the float chamber of the carburetor to be reliably returned to the fuel tank by intake negative pressure accumulated in the negative pressure surge tank and, furthermore, residual fuel can be vented by the changing over of a single changeover cock, thus enabling the number of components to be reduced and the device to be provided at a low cost.

A ferroelectric memory device equipped with a plate line control section that selects a specified plate line that is connected to a specified memory cell, thereby discharging a data accumulation charge to a specified bit line connected to the specified memory cell, and discharges a reference accumulation charge to the specified bit line when the specified bit line is discharged; a device that, by successively connecting the specified bit line to a first sense amplifier line and a second sense amplifier line based on a change in the potential on the specified plate line, retains at the first sense amplifier line a potential on the specified bit line when the data accumulation charge is discharged, and retains at the second sense amplifier line a potential on the specified bit line when the reference accumulation charge is discharged; and a sense amplifier that judges the predetermined data based on potentials on the first sense amplifier line and the second sense amplifier line.

The invention relates to a device for supplying a reducing agent into an exhaust system of an internal combustion engine. The device includes a delivery pump for delivering the reducing agent from a storage tank into an exhaust tube of the exhaust system. A metering device is provided between the delivery pump and the exhaust tube, which metering device supplies reducing agent, which is delivered continuously by the delivery pump, in an intermittent fashion into the exhaust tube.

The present invention relates to a method for operating a ground milling machine which comprises at least one height-adjustable milling roller, wherein the milling roller performs a tumbling movement (T′) which is controlled by way of open-loop and / or closed-loop control during lowering in operation. The present invention further relates to a control device for the closed-loop and / or open-loop control of this method, and also to a ground milling machine with such a control device.

In a gate driving circuit and a display apparatus having the same, a ripple preventing part is connected to a pull-up part and a control terminal (Q-node) to reset the Q-node. The ripple preventing part includes a first ripple preventing device that resets the Q-node during a high period of the first clock within a (n−1)H period, and a second ripple preventing device that resets the Q-node during a high period of a second clock within the (n−1)H period. A back-flow preventing device is connected between a previous carry node and the second ripple preventing device to prevent an electric charge of the Q-node from flowing back to the previous carry node.

A neutron-optical component array in which the beam paths of the individual moderators are combined in a concerted manner so as to create a superimposed neutron beam with an effective mean beam direction. The superimposed neutron beam has a multi spectrum composed of the single spectrums of several moderators, whereby a larger spectral width is obtained, making various applications in different neutron energy fields possible. The multi spectrum can be further improved in terms of the intensity thereof and the beam quality by adding further neutron-optical components, particularly in the form of an energy-depending switching super reflector, and by switching between moderators.

A structural part for a motor vehicle includes an inner component having a generally rectangular cross section and configured in the form of a multichamber hollow section made of light metal, and an outer component having a generally rectangular cross section. The inner and outer components are movable in a telescoping manner relative to one another between an idle state and an activated state. A first locking mechanism is provided to lock the idle state and a second locking mechanism is provided to lock the activated state. The movement of the inner and outer components from the idle state to the activated state is hereby realized by an actuator.
