Abstract: A semiconductor device is provided that includes a first n+ region, a first p+ region within the first n+ region, a second n+ region, a second p+ region, positioned between the first n+ region and the second n+ region. The first n+ region, the second n+ region and the second p+ region are positioned within a p? region. A first space charge region and a second space charge region are formed within the p? region. The first space region is positioned between the first n+ region and the second p+ region, and the second space region is positioned between the second p+ region and the second n+ region.

Abstract: A machine tool in the form of a hand-held power tool or a semi-stationary machine tool, the machine tool having a tool holder for holding a work tool, a drive motor for driving the tool holder and at least one electrical function unit, the machine tool having a control device for actuating the at least one electrical function unit using at least one actuation function, the at least one electrical function unit being designed to perform an output function depending on the actuation by the at least one actuation function, and the machine tool having at least one operation element, which can be moved by an operator of the machine tool between a first operation element position and at least one second operation element position to actuate the control device.

Abstract: An oil activated fuel injector includes a clevis having an optimized geometry. The optimized geometry substantially eliminates side loading effects of a plunger during operation, thereby maintaining performance integrity of the fuel injector. The optimized geometry includes a profile larger than a head portion of a plunger in order to allow the plunger to free float.

Abstract: An oil activated fuel injector which provides a pilot quantity of fuel prior to the main fuel injection event. A control system for a fuel injector includes a sensor for providing a signal to a control which is indicative of an opening motion of a spool. The control initiates a pull back of the spool, upon receipt of the signal, to eliminate a bounce back phenomenon of the spool during an injection of a pilot quantity of fuel. The signal may be representative of a pressure of working fluid or fuel, as well as a position or acceleration of the spool.
