摘要： A power amplifier circuit that has an inductor and capacitor connected to one end of the output winding of an RF transformer. The other end of the output winding is connected to a resistor that in turn is connected to ground. The transformer has two primary windings. Both primary windings have one end connected to a variable DC voltage supply. The other end of each primary winding is attached to a switch, such as a MOSFET. All three windings are wound around a core. Current flowing from the DC voltage supply to the switches causes a magnetic flux in the core. A voltage is generated on the secondary winding resistor. This voltage is fed back to the switches, controlling on and off timing. In this way the need to measure and record natural frequency is eliminated.

摘要： A brake rotor for a vehicle and method of construction thereof provides a cast iron disc with a first coating of a ceramic anti-wear material adhered to the cast iron disc to provide an annular friction surface for braking engagement with a brake pad. The disc has a second coating different from the first coating. The second coating is adhered to the disc to provide an annular non-braking surface spaced from the friction surface. The non-braking surface provided by the second coating is resistant to corrosion.

摘要： A method of sputter depositing silver selenide and controlling the stoichiometry and nodular defect formations of a sputter deposited silver-selenide film. The method includes depositing silver-selenide using a sputter deposition process at a pressure of about 0.3 mTorr to about 10 mTorr. In accordance with one aspect of the invention, an RF sputter deposition process may be used preferably at pressures of about 2 mTorr to about 3 mTorr. In accordance with another aspect of the invention, a pulse DC sputter deposition process may be used preferably at pressures of about 4 mTorr to about 5 mTorr.

摘要： A brake disc assembly comprises a rotor and a hat assembly. The hat assembly is comprised of two hat portions, each having a plurality of curved projections. The curved projections interact with radial recesses formed in the rotor to ensure a secure connection between the hat assembly and the rotor over a wide range of operating conditions.

摘要： A dual event valve control system for an internal combustion engine. The system includes an inner rocker arm in engagement with a valve and with a first cam, an outer rocker arm in engagement with a second cam, and a latch member which is insertable between the rocker arms, whereupon when the rocker arms do not engage the latch member, the rocker arms are free to pivot independently of one another and the valve is actuated by the first rocker arm in accordance with the lift profile of the first cam, and when the rocker arms are engaged by the latch member, the rocker arms rotate in unison and the valve is actuated by the second rocker arm in accordance with the lift profile of the second cam. A stop acting between the inner and outer rocker arms limits relative pivoting movement between the rocker arms and is effective to provide clearance between the base circle portion of its second cam and the outer rocker arm.

摘要： A piston for an internal combustion engine is provided. The piston includes a body having a cylindrical outer surface with a ring belt region including an annular uppermost ring groove and a lower ring groove extending into the outer surface. A top land extends from the uppermost ring groove to an upper combustion surface. The body has a pair of pin bosses with pin bores aligned with one another along a pin bore axis. A first piston ring is disposed in the uppermost ring groove and a second piston ring is disposed in the lower ring groove. The body has an annular sealed cooling gallery with a cooling medium contained therein. The sealed cooling gallery is configured in substantial radial alignment between the first and second piston rings to provide optimal cooling to the ring belt region, top land and upper combustion surface.
