Filed: 1996-12-14
Abstract: The invention relates to an instrument for measuring eddy currents for a tachometer, comprising a radially magnetized permanent magnet (4) and a second axially magnetized permanent magnet (8). The radially magnetized permanent magnet (4) is used to generate eddy currents in an eddy current body (2), which moves a needle (7) placed on a centre arbor (1). The second, axially magnetized permanent magnet (8) is mounted a short distance opposite to a fixed Hall element (10). To generate an especially powerful magnetic field the permanent magnet (4) of the eddy current body (2) is magnetized diametrically. The second permanent magnet (8) comprises several pairs of magnetic poles and permits a high resolution of the angle of rotation of a drive shaft (3).

Patent DE-19701752-A1 (DE)
Inventor: TOZZI LUIGI P
IPC: H01T13/50
Filed: 1997-01-20
Abstract: A variable length arc magnetic spark plug includes an insulating shell with a cavity 64, a pair of electrodes 26,28 (fig.3a) or 66,68 (fig.8) spaced by a diverging air gap so as to define a variable length air gap, and a pair of magnets 32,34 that produce a magnetic field in the air gap. The magnitude of an ignition signal supplied to the electrodes 26,28 directly affects the force acting on the arc to move or position the arc 10 relative to the magnetic field produced by the magnets 32 and 34 in accordance with well known field principles. Less current is required to produce a larger or longer arc with the inclusion of the magnets 32 and 34 in the vicinity of the air gap wherein the electrical arc is generated. The insulator may be made from silicon nitride, the electrodes fron steel or aluminium and the magnets from sumarium cobalt.

Title: IC engine fuel characteristic, particularly evaporation properties, determination device
Inventor: OHSAKI MASANOBU
IPC: F02D41/06
Filed: 1997-01-24
Abstract: The engine management system monitors the rate of change of engine speed from cold starting and the time taken to reach a reference speed. The monitoring is performed over a set number of engine cycles and the results are compared with stored values to determine the type of fuel used e.g. light fuel or heavy fuel.  Fuel identification is automatic and the result is used to adjust the ignition and the fuel injection etc. to obtain optimum engine settings to match the type of fuel. Three main parameters are monitored; the starting mode of the engine, the variation in engine speed and the gradient of engine speed with respect to time.

Patent DE-19708962-A1 (DE)
Inventor: ZETTLER THOMAS DR
IPC: G11C29/00
Filed: 1997-03-05
Abstract: The invention relates to a memory, in particular a semiconductor memory, characterized in that it has at least one memory cell field (2) containing memory cells (S1), whereby the memory cells (S1) can be selected by applying at least one selection signal to selection lines provided for in the area of said memory cells (S1), said selection lines having word lines (XSEL 0, ..., XSEL n) and/or bit lines (YSEL 0, ..., YSEL n); a redundancy circuit (3, 7) comprising at least one redundancy memory cell (RS1), whereby said redundancy memory cells (RS1) can be selected by applying at least one redundancy selection signal to redundancy selection lines (RXSEL0, ..., RXSEL3; YSEL 0, ..., YSEL n) provided for in the area of the redundancy memory cells (RS1); and a redundancy selection line selection circuit in which at least one item of allocation information can be stored, said redundancy selection line selection circuit being configured in such a way that on the basis of the allocation information at least one redundancy selection line (RXSEL0) can be assigned to at least one redundancy selection line (RXSEL0). When individual memory cells and/or entire word lines are replaced by redundancy cells in generic flash memories, particularly flash memories fitted with advantageously sized stacked-gate memory cells, said memory cells have a disruptive effect during normal operation. This prevents the use of redundant word lines. The invention therefore aims to provide a generic memory with a simple structure which can operate normally when memory cells are replaced by redundant word lines. To this end, the invention provides for the memory cells (S1, 15) to be configured in such a way that they can be erased by means of positive voltage and programmed by means of negative voltage.

Inventor: WRAGE STEPHAN
IPC: G06K19/18
Filed: 1997-05-16
Abstract: The invention relates to a flat element with a storage medium or a microprocessor, e.g. chip cards or magnetic cards. In the case of existing card-shaped elements, it is very difficult to distinguish them optically or optionally by touching them. The invention seeks, therefore, to reduce the amount of material required while at the same time enabling differentiation of said card-shaped elements according to their shape. To do this, the inventive elements, on or in which storage media or microprocessors are arranged, are configured in such a way that an indented edge area enabling individual configuration of said element is formed so that preferably a configuration differing from the common rectangular shape is obtained.
