Display device, with a plurality of display elements arranged in the shape of a bar, wherein each display element can represent at least one first display state (off) and one second display state (on), and a value being shown can be indicated by the second display state (on) of at least one display element assigned to the value, so that an intermediate value between the value being displayed and a succeeding or preceding value can be represented by activating the preceding or succeeding display element.
摘要:
The transmission power of a fill level radar is varied in that the transmission power is switched, by a signal switch, from a first transmission power to a second transmission power. This switching takes place, for example, by bypassing the high-frequency amplifier or by switching off a drain voltage.
摘要:
A high-frequency module is for fill level measuring and for use at frequencies of more than 75 GHz. The high-frequency module comprises a microwave semiconductor, a printed circuit board and a housing bonded to the printed circuit board. In order to reduce the power required, operation of the microwave semiconductor takes place in a pulsed manner.

An impact protection plate is provided for mounting on the structure of an aircraft. The impact protection plate includes a first layer, close to the aircraft, made of a fiber-reinforced plastic having a wave-shaped pattern of alternating elevations and depressions, the transverse tensile strength of the fiber-reinforced plastic being greater than 50 MPa. The impact protection plate includes a second layer situated on the first layer, remote from the aircraft, and is made of a fiber-reinforced plastic, the elongation at break of the reinforcement fibers being greater than 3%.

A decoupling element for a fuel injection device provides a low-noise construction. The fuel injection device has at least one fuel injection valve and a receiving bore in a cylinder head for the fuel injection valve as well as the decoupling element between a valve housing of the fuel injection valve and a wall of the receiving bore. The spring rigidity of the decoupling element is so low and the decoupling element is placed between the valve housing of the fuel injection valve and the wall of the receiving bore in such a way that the decoupling resonance is located in the frequency range below 2.5 kHz. The fuel injection device is particularly suitable for the direct injection of fuel into a combustion chamber of a mixture-compressing spark-ignited internal combustion engine.

A vibrating plate comprises a vibration generator device, which can be controlled in such a manner that the direction of the action of force can be set at a number of locations, particularly in more than two locations. In addition, an advance adjusting device is provided for controlling the vibration generator device whereby the direction of the action of force is set in a position in which a maximum possible advance of the vibrating plate is reached. The direction of the action of force can be changed according to a change in the surroundings of the vibrating plate, particularly to the slope and/or the hardness of a subsoil to be compacted by a soil contact plate. Alternatively, the direction of the action of force can be changed according to the wishes of the operator.
摘要:
An exhaust purification apparatus for internal combustion engine having a selective reduction catalyst that while maintaining a high NOx reduction ratio, inhibits any ammonia discharge downstream of the selective reduction catalyst. In the exhaust purification apparatus (2), a urea selective reduction catalyst (23) comprises a first selective reduction catalyst (231) and, provided downstream of the first selective reduction catalyst (231) in an exhaust passageway (11), a second selective reduction catalyst (232). Further, the exhaust purification apparatus (2) includes a urea injection unit (25) for feeding of a reducing agent upstream of the urea selective reduction catalyst (23) in the exhaust passageway (11) and an ammonia sensor (26) for detection of the ammonia concentration at a site between the first selective reduction catalyst (231) and the second selective reduction catalyst (232) in the exhaust passageway (11). The rate of urea injection, GUREA, by the urea injection unit (25) is determined so that the value of ammonia concentration, NH3CONS, detected by the ammonia sensor (26) is greater than “0.”
