  • Safety and arming unit for a spinning projectile fuze
    Patent number: 7661364
    Abstract: A safety and arming unit (11) which is designed in particular for an electrical fuze circuit (27) does not reliably respond just to lateral loads on one side, but responds only to centrifugal forces produced by the spin during free flight, in that two contact pairs (22-23, 22-23) which are connected electrically in parallel with one another via rings (14, 15) and are arranged diametrically opposite one another on a cross-sectional plane of the fuze (12) are both no longer electrically conductively bridged at the same time by the bolt (17) because, just by virtue of the centrifugal force, both bolts (17) are simultaneously moved radially outwards from their short-circuit safety positions in their blind holes (16), which are oriented transversely with respect to the rotation axis (13).
    Type: Grant

  • SIC field-effect transistor array with ring type trenches and method of producing them
    Patent number: 5747831
    Abstract: SiC field-effect transistors with source, gate and drain contacts and in which the source contacts are located on the surface of the semiconductor wafer, the drain contacts on the underside of the wafer and the gate contacts in trench-like structures. The trench-like structures surround the source electrodes of the transistors in the shape of a ring and the gate contacts are connected to each other on the floors of the trenches.
