摘要:
Embodiments of the present invention provide a method and memory device for storing and reading data. In one embodiment, the probe is positioned proximate to an area of a solid electrolyte layer in which the data is to be stored. A voltage difference is created across the solid electrolyte layer by applying a first voltage to a first side of the solid electrolyte layer via a tip of the probe and applying a second voltage to a second side of the solid electrolyte layer via an electrode layer coupled to the solid electrolyte layer. The voltage difference applied across the solid electrolyte layer causes ions from the electrode layer to be introduced into the solid electrolyte layer, creating a lowered resistance in the solid electrolyte layer. The lowered resistance corresponds to a first logical value stored in the solid electrolyte layer.

An apparatus for posttreatment of exhaust gases of an internal combustion engine, using a reducing agent to be introduced into the exhaust gases, in particular a urea or a urea-and-water solution, having an improved mixing chamber into which stored reducing agent, via a reducing agent line, and compressed air via a compressed air line can be introduced to create a reducing agent-air mixture, and means for preventing a reverse flow of reducing agent or reducing agent-air mixture from the mixing chamber into the compressed air line are provided which have a spring-loaded sealing hose. This arrangement assures secure sealing off of an attachable compressed air system from the corrosive reducing agent.

A micromechanical infrared radiator has a radiator surface supported in a carrier chip. The radiator surface can be heated by a heating device. As a function of a temperature measurement, the heating power can be controlled such that the radiator surface assumes a defined temperature. For direct temperature measurement, a micromechanical temperature sensor in the form of a metal resistance is integrated in the radiator surface.

摘要:
There is disclosed a tri-state buffer circuit for receiving an input signal at a buffer input node and transmitting, responsive to a buffer enable signal, an output signal at a buffer output node. The buffer circuit includes an input stage coupled to the buffer input node. The input stage is configured to receive, when the buffer enable signal is enabled, the input signal. The buffer circuit further includes a level shifter stage coupled to the input stage. The level shifter stage is arranged to output, when the buffer enable signal is enabled, a set of level shifter stage control signals responsive to the input signal. A voltage range of the set of level shifter stage control signals is higher than a voltage range associated with the input signal. The buffer circuit also includes an output stage coupled to the level shifter stage. The output stage is configured to output, when the buffer enable signal is enabled, the output signal on the buffer output node responsive to the set of level shifter stage control signals. The voltage range of the output signal is lower than the voltage range of the set of level shifter stage control signals. The output stage decouples the buffer output node from the input stage and the level shifter stage when the buffer enable signal is disabled.

摘要:
A process is disclosed for preparing .alpha.-branched aliphatic monocarboxylic acids with 12 to 48 carbon atoms. In a first step of the process (a), .alpha.-branched aliphatic monohydric alcohols (Guerbet alcohols) are converted in the presence of caustic alkali into the alkali salts of the corresponding .alpha.-branched aliphatic monocarboxylic acids. In a second step of the process (b), the .alpha.-branched aliphatic monocarboxylic acids are released from the alkali salts by soap splitting in the presence of an inert diluting agent.
