摘要： This composite semiconductor device has a normally-on first field effect transistor and a normally-off second field effect transistor connected in series between first and second terminals, gates of the first and second field effect transistors being connected to second and third terminals, respectively, and N diodes being connected in series in a forward direction between a drain and a source of the second field effect transistor. Therefore, a drain-source voltage (Vds) of the second field effect transistor can be restricted to a voltage not higher than a withstand voltage of the second field effect transistor.

摘要： A protective cowling arrangement for the power head of an outboard motor and an air inlet arrangement therefor. The cowling arrangement is comprised of a cowling portion that defines an internal area in which the engine of the outboard motor is contained and a pair of expansion chambers formed on opposite sides of the cowling assembly and each of which is provided with a respective air delivery port at a forward end thereof for increasing the air flow area available to the interior of the cowling assembly and for placing the point of air admission away from components of the associated engine that should be protected. An improved water gutter and drain arrangement is also employed to prevent water from entering into the engine area.
