摘要:
The MRAM semiconductor memory configuration has MRAM main cell arrays in the form of a crosspoint array or a transistor array together with redundant MRAM cell arrays formed of redundant MRAM memory cells arranged in a plurality of planes and provided on the same chip. The redundant MRAM cell arrays are distributed over the individual planes of the memory matrix or one plane of the memory array is used in its entirety for providing redundant cell arrays.

A current driver configuration for MRAMs includes word-line drivers and bit-line drivers at respective first ends of word lines and bit lines. The word line drivers and the bit line drivers each include a series circuit formed by an n-channel field-effect transistor and a current source. Further series circuits are provided at the respective second ends of the word lines and the bit lines. Each of the further series circuits includes a second n-channel field-effect transistor and a voltage source.

A device, having a plastic molded part (1), in particular an add-on part and/or trim part for a motor vehicle, comprises a cover (2) for closing an opening (3) in a wall (4) of the plastic molded part (1). The cover (2) has a first rim (6) and a second rim (7), substantially opposite of the first rim (6), wherein the cover (2) has at least one retaining hook (9), which engages behind the opening (3) in the closed position of the cover (2), on the inner side (8) facing the opening (3) in the region of the first rim (6), and the cover (2) further has at least one detent element (10) on the inner side (8) in the region of the second rim (7), said detent element being latched in the closed position of the cover (2) to at least one detent counter element (11), fixedly attached to the wall (4). The cover (2) has at least one further additional detent element (12) on the inner side (8) in the region of the first rim (6), said element interacting with at least one additional detent counter element (13) at the wall (4), so that the cover (2) is held in the closed position at least substantially without prestress with respect to the opening (3).
摘要:
The invention relates to a gas detection system (1) for detecting gases, vapors and biological pathogens, having at least one receptor (4) arranged on a line (5) connecting the ambient air (7) to an air storage unit, wherein the gas detection system (1) is designed as a “breathing” system containing clean CO2-carrying and moisture-saturated air in the air storage unit (2), wherein the operating temperature of the gas detection system (1) is the room temperature. Additionally, a method is proposed for detecting gases, vapors and biological pathogens using the inventive gas detection system. This avoids the shortcomings of the known solutions of the prior art, and an improved and more cost-effective solution for detecting trace gases is made available.
摘要:
A device for the detection of micro particles that can be marked by probes or antibodies capable of being detected by radiation has a filter, a supply system, and a detection system. Fluid to be examined is passed over a filter to filter out the micro particles and to perform the marking steps by supplying corresponding marking substances to the filter.

The present invention relates to novel substituted bicyclic lactones, to processes for their preparation and to their use for the prevention and/or treatment of disorders caused by hyper- or hypofunction of the glutamatergic system, in particular of cerebral ischaemias, cranial cerebral trauma, states of pain or CNS-mediated spasms.
摘要:
In a method for reliably removing liquid fuel from the fuel system of a gas turbine after shutting down the same, in the case of which fuel system liquid fuel is fed via at least a first feeder line in normal operation of the gas turbine to a burner and injected there into a combustion chamber via fuel nozzles, a high reliability against explosion and coking is achieved in a simple way by virtue of the fact that the liquid fuel is flushed from the fuel system by the use of an inert auxiliary medium.
摘要:
A memory device is configured to guarantee a high degree of flexibility and a compact construction. To this end, the existing plate line device of the memory device which functions on the basis of a hysteresis process is configured to detect the state of a memory capacitor and hence, the information that is stored.
摘要:
A melt spinning apparatus for spinning a synthetic yarn, wherein the yarn is formed by combining a plurality of filaments and wound to a package by means of a takeup device downstream of the spinning apparatus. Downstream of the spinneret, an inlet cylinder with a gas-permeable wall and a cooling tube are arranged. The cooling tube connects to a suction device such that an air stream forms in the cooling tube in the direction of the advancing yarn. This air stream assists the advance of the filaments and leads to a delayed cooling. To ensure adequate cooling of the filaments within the cooling zone, an air supply device is provided for generating an additional cooling air stream which flows in the axial direction of the cooling tube for cooling the filaments downstream of the inlet to the cooling tube.
