Abstract: In a semiconductor device a field effect transistor of either the lateral or vertical type has an island-shaped first region (1) which is bounded at the bottom by a first p-n junction (5) having a high breakdown voltage and laterally by a second p-n junction (6) having a low breakdown voltage. The first junction (5) is formed with an underlying second region (2) of opposite conductivity type to the first region (1) and can be reverse-biased by applying a voltage between the second region (2) and a contact region (4) which forms a non- rectifying contact with the region (1). The doping and thickness of the first region (1) are so small that, before breakdown at the second junction (6) occurs, the part of the region (1) situated between the second junction (6) and the contact region (4) is fully depleted by the depletion zone extending from the reverse-biased first junction (5). In Figure 2 this contact region (4) belongs to the drain electrode (D), but in other embodiments it belongs to the source electrode (S) or gate electrode (G). In Figure 2 the transistor has a junction gate (7) but in other embodiments it may have an insulated gate or a Schottky gate. Integrated complementary transistors each in accordance with the invention may be formed (Figure 3) using a double epitaxial layer structure for the first and second regions (1 and 2). <IMAGE>

Date Sep. 1, 1983.An electronic current interrupter included in a DC distribution system contains a transistorized power circuit (EK), a threshold circuit (JF), a time circuit (TK) and holding circuit (HK). In one embodiment, the power circuit comprises a power transistor (T1) connected in series with the load and with a resistor (R1) in the threshold circuit. There is a current-limiting path containing a transistor (T2) and a current-limiting resistor (R4) in parallel with a power transistor (T1). When the load current exceeds a given value, the threshold circuit sends a voltage blocking the power transistor (T1) simultaneously as the transistor (T2) in the current-limiting path becomes conductive. After a given time (t), determined by the time circuit (TK), the holding circuit sends a voltage which also blocks the transistor (t2) in the current-limiting path, and the power circuit (EK) becomes entirely non-conductive to the load current.

Abstract: Method and means relating to traction-thrust magnets are proposed for providing more than one traction-thrust position by means of amperages adjusted thereto. A magnet comprises a core unit (5) in the form of two or more movable parts (7, 8) cooperating with a solenoid (3). When electric current is supplied to the solenoid, magnetic fluxes (19, 20) of corresponding magnitudes are generated within the solenoid, which fluxes cause a movable soft-magnetic core part to move in the longitudinal direction of the flux. A first core part (7) screens magnetically the other core part or parts, which screening effect is overcome when a magnet flux (20) of a predetermined magnitude is supplied. A traction means, or a thrust means, secured to a movable core part then moves correspondingly.

Abstract: A process for obtaining a plate of zirconium alloy comprising at least one portion of excess thickness of at least 0.5 mm relative to a large adjacent face, the portion having edges with angles equal to 90 DEG  to 105 DEG  and flanks which are connected without depressions to the large adjacent faces. According to the process, a surface portion of a blank plate located straight above a desired portion of excess thickness is coated with a continuous coating which is resistant to a pickling composition to be used, the coated portion widened beyond the desired portion of excess thickness by 0.5-1.5 times the amount of the excess thickness. The coated blank plate is immersed a plurality of times, without passage of electric current, in a pickling bath comprising HF, an oxidizing agent and water, and having a dissolved Zr content less than 12 g/l and a temperature below 35 DEG  C. Each immersion removes less than 0.3 mm of thickness over the portions of the blank plate which are not coated. Subsequently, the coating is removed and the blank plate is immersed in the pickling bath for a final treatment. This process can be employed for the preparation of plates of great length which are to be folded, each portion of excess thickness being placed inside a folded angle, in particular to form boxes for ducts for the circulation of fluids.
