Patent EP-0360700-A1 (EP)
Inventor: BOURZGUI NOUR-EDDINE
IPC: G01R31/28
Filed: 1989-09-22
Abstract: The invention relates to the measurement of magnetoelectric effects, and more particularly to the measurement of magnetoelectric effects in specimens of semiconductor material. There is proposed a probe for measuring magnetoelectric effects, characterised in that it comprises a metallic plane covered with a substrate (10) having an electrically conductive surface and an electrically insulating upper surface comprising four electrodes (12, 14, 16, 18) each having a free end, the free ends of the electrodes being opposite to one another and being separated from one another by a free space, the ends of the electrodes and possibly the free space being covered with a dielectric layer (36). A specimen (40) of semiconductor material is applied to this probe and there is applied to the specimen by capacitive coupling an ultra-high-frequency current on one of the electrodes; the resultant signal is read, in the presence of a magnetic field, on the other three electrodes. <IMAGE>

IPC: B61F1/04

Abstract: It is intended to permit the traction and pushing of railway wagons which at the same time are able to move on a road in order to perform various tasks. On bends, the lateral forces tend to cause the device to be derailed towards the outside of the bend. The currently known devices are equipped with rigid frames with long wheel bases, and in order to cancel out these lateral forces they must exert a substantial pressure on the guide wheels (7-8). Since the driving mass is reduced, the traction force is small. These disadvantages are eliminated by using the articulated frame since the articulated frame provides ideal taking of the bends (Fig. 2) and enables the pressure on the guide wheels (7-8) to be reduced. The driving mass (5, 6) is consequently greater, to the advantage of the traction force, whilst providing maximum safety. <IMAGE>

Abstract: The hydraulic control device has a flow regulating valve (16) and a brake device (51, 52, 71, 89). In a braking sequence the pressure medium delivered by the pump is controlled by way of the flow regulating valve and a non-return valve (38) for the brake cylinder (89). At the same time pressure is exerted on the piston (52) and slide (51), by means of which the latter is adjusted in such a manner that a control oil flow from the pump to the reservoir is interrupted and pressure medium can flow to the brake device. In order to achieve unrestricted damping movement of the control slide (15), the pressure medium contained in an annular chamber (90) located between the slide (51) and a sealing sleeve (54) must flow out via a restrictor orifice plate (91). <IMAGE>

Abstract: The invention relates to a method for converting the measurement signals from bridge circuits into digital values by means of the PPDM converter described in DE 3814941. For this purpose, the PPDM convertor is charged with a current iR+iE which corresponds to the voltage drop Uo+Um across the active sensing impedance, and is discharged with a current iC which corresponds to the voltage drop Uo across a passive reference impedance. The method combines the high conversion accuracy of the PPDM convertor with the advantages of simple bridge circuits to form a higher-level conversion function which, compared with conventional conversion methods, is distinguished by clearly reduced complexity. <IMAGE>

The field windings are on the stator (50) with the winding leads windings being accessible externally of the stator for enabling switching devices to be utilized for changing of the number of turns of the stator windings for thereby varying the motor characteristics, as needed. The switching devices may be mechanical switch devices or static semiconductor switch devices. In a second embodiment, commutation is effected by non-contact position sensing devices, such as encoder wheels, optical devices and the like, operable in response to a rotating device keyed to the rotor shaft, which device is positioned for electromagnetic accuracy relative to the pole positions of the stator of the machine. Other embodiments are disclosed. With accessible external leads, the machine may be alternately used as both a propulsion motor and generator in the same device for returning power to the direct current source.

Abstract: In a serial data communications system, an embedded clock is recovered from a data signal by incrementally controlling the frequency (thus phase) of a voltage-­controlled oscillator (42) in response to the difference in phase between the incoming data signal (13) and the clock oscillator output (43). A transition of the data signal is detected and used to initiate a control pulse which is terminated upon the next transition in the clock oscillator output (43). A reference pulse is also generated which has a width about equal to a half cycle of the clock. These pulses are used to generate the voltage control for the oscillator, so that the phase relationship varies to seek an equilibrium where the pulses are of equal width and the transitions of the clock are at midpoint of potential transitions of the data signal. The control can tolerate relatively long periods where there is no transition of the data signal. The control circuitry includes a counter for counting transitions of the clock to inhibit another detect operation from starting until three transitions after one has begun.
