    • A conductivity-modulation MOSFET employs a substrate of an N type conductivity as its N base. A first source layer of a heavily-doped N type conductivity is formed in a P base layer formed in the N base. A source electrode electrically conducts the P base and the source. A first gate electrode insulatively covers a channel region defined by the N.sup.+ source layer in the P base. A P drain layer is formed on an opposite substrate surface. An N.sup.+ second source layer is formed in a P type drain layer by diffusion to define a second channel region. A second gate electrode insulatively covers the second channel region, thus providing a voltage-controlled turn-off controlling transistor. A drain electrode of the MOSFET conducts the P type drain and second source. When the turn-off controlling transistor is rendered conductive to turn off the MOSFET a "shorted anode structure" is temporarily formed wherein the N type base is short-circuited to the drain electrode, whereby case, the flow of carriers accumulated in the N type base into the drain electrode is facilitated to accelerate dispersion of carriers upon turn-off of the transistors.

    • An overcurrent protective circuit for a modulated conductivity type MOSFET, i.e., a BIFET, which has a voltage detection circuit for detecting a voltage between the drain and source of the BIFET and a main switching circuit for lowering a voltage between the gate ad source of the BIFET and preventing the failure of the BIFET and delay of turn-on of the BIFET according to the output of the voltage detection circuit. The protective circuit produces a constant time delay before the main switching circuit becomes turned on during the initial turn-on period of the BIFET upon application of an ON-gate signal to the gate of the BIFET. The protection circuit thereby prevents, during the initial turn period of the BIFET, a situation where the main switching circuit is turned on but the BIFET is not turned on. The protective circuit further assures that after detection of an overvoltage across the source and drain of the BIFET as may be caused by a load failure, the BIFET gate is maintained at such a low voltage to assure at most a small current conduction through the BIFET even if a ringing voltage occurs across the BIFET.

    • A hydrostatic extrusion method and apparatus for the extrusion of tubes is disclosed wherein the simplified structure of the nose or tip portion of the billet and the cooperating surfaces of the die defining the die cavity and those of the mandrel facilitate an improved initial sealing among the associated surfaces of the die, billet and mandrel. Such an initial sealing is effected between such interfaces of the members and billet at a point which is located substantially rearwardly from the position at which the actual extrusion to the final tubular configuration occurs between the bearing portion of the die and the cooperating sizing portion of the mandrel. Such structure and method permits the extrusion of tubes having walls of asymmetric or non-circular configurations in cross section, even those of complex configurations. In order to further enhance the efficacies of the present invention, the mandrel is provided with a head portion which may be replaced, or exchanged as desired, and a position-aligning member is associated with the mandrel in order to maintain the proper orientation of the mandrel relative to the die. The mandrel may also have a specifically designed configuration in order to provide the inner surface of the tube extruded with a gloss finish.
