Inventor: SCHWARZ MICHAEL
IPC: D21F1/70
Filed: 1992-05-12
Abstract: To process used paper, for recycling, a selective flotation is used for ink removal followed by at least one further cleaning flotation stage, using a multistage flotation for the selective flotation. The collected flotation foam is gathered together at the laest after the third flotation and cleaned in a total flotation through pressure relaxation.

With a double-stage sieve action, the coarse particles in the first fraction are mostly retained. The material with a fibre content is sepd. as a third fraction at the second stage and returned to a point in front of the selective flotation. The material contd. in the fourth fraction, together with the first fraction, is passed to the total flotation.

Abstract: MOSFET, connected to a load via the drain contact, and having a grounded source contact, comprises: an insulation plate (12) attached to a heatsink (11); to the insulating plate (2) a conductive drain contact plate (13D) and source contact plate (13S) are attached, pref. at some distance from each other; on the source plate (13S) a gate contact (13G) is bonded via an insulator (20), which is pref. about 1mm thick. The MOSFET die is attached to the drain plate (13D), forming an electrical connection to the drain diffusion region. Then the gate and source contacts are electrically connected using wire-bonding. The gate plate (13G) and insulator are pref. smaller than that of the source (13S). A diode is pref. bonded to the drain plate (13D) and connected electrically, via a bondwire, to the source plate (13S). The module can be built by adding the separate components in the right order or using sub assemblies such as one comprising the source-plate (13S), gate insulator and gate electrode plate (13G). USE/ADVANTAGE - Removes the parasitic capacitance between gate and drain plates which is present in the conventional module. This is achieved by using the source plate as a shield. As a result the devices are more suitable for high frequency operation. The removal of the capacitance has removed the problem of oscillation of the transistor due to drain voltage transients being coupled to the gate by the capacitance. The device is surrounded with a frame and assembled in plastic.
