Patent DE-3465859-D1 (DE)
Title: Electronic switch
Inventor: STRACK HELMUT DR PHIL
IPC: H03K17/732
Filed: 1984-12-17
Granted: 1987-10-08
Abstract: Connected in series with a thyristor (1) are two IGFETs (2, 3) one to the anode side and the other to the cathode side. Between the inner thyristor zones (6, 8) and the outer IGFET connections, a threshold circuit (10, 11) is connected to each. The threshold voltage of the threshold circuit is higher than that of the p-n junctions between the outer and adjacent inner thyristor zones (6, 7; 8, 9) including the voltage drop of the conducting IGFET. The switch is turned off by operating to turn off the IGFETs. The current then flows via the threshold elements through the two inner zones (6, 8). The charge carriers of this diode are evacuated very quickly, since carrier injection from the outer zones is no longer possible.

Abstract: 57 In an optical receiver for the reception of a modulated light beam, the beam falls on a PIN diode (D1) connected to the input of an amplifier (-A) which has a feedback resistor (R1) across it. This resistor is shunted by the series combination of a Schottky diode (D2) and of a PIN diode (D3). The former diode ensures that a high magnitude pulse does not leave the receiver undesirably insensitive to a following smaller pulse. The latter diode, due to its low self-capacitance and low leakage, overcomes distortions due to the Schottky diode's higher self-capacitance and leakage. These effects are enhanced by providing. the series-connected diodes with a low value (e.g. 0.2 volts) of reverse bias, due to the different connections of the diodes (D2, D3) and the feedback resistor (R1) to a potential divider (R2, R3) between the amplifier output and a point at a reference potential.

Title: Pressure plate for a mine, in particular an anti-tank mine, and a mine provided with such a plate
Inventor: BARICOS JEAN
IPC: F42C7/06
Filed: 1987-01-27
Granted: 1989-02-16
Abstract: A pressure plate for a mine comprises a hydraulic circuit. The mine is triggered by complete depression of the pressure plate. The hydraulic circuit comprises a pressure chamber containing a fluid that is compressed by a force applied to the pressure plate. The fluid is evacuated from the pressure chamber in a controled manner through a depressurization unit in response to a sustained force greater than a predetermined threshold being applied to the pressure plate. A bistable member moves between a first position in which it prevents communication between the pressure chamber and the depressurization unit and a second position in which it establishes communication between the pressure chamber and the depressurization unit. The bistable member is initially in the first position when no force is exerted on the pressure plate. It remains in the first position so long as the pressure plate is subjected to an increasing or stable force. It switches to the second position when the pressure of the fluid decreases after it has increased due to a force of this kind. Thus, after increasing to a maximum value and then decreasing to a minimum value, any increase in the force results in depressurization of the fluid and complete depression of the pressure plate. This explodes the mine.
