摘要： An engine system having a compressor coupled to an engine and supplying air to an intake manifold, a throttle controlling the supply of air from the compressor to the intake manifold, a compressor recirculation valve (CRV) having a pneumatic control chamber, and a throttle aspirator having its motive section in fluid communication with an inlet of the throttle and its discharge section in fluid communication with an outlet of the throttle and its suction port in fluid communication with the pneumatic control chamber of the CRV. Such an engine system automatically minimizes surge during boost without a control system activating the CRV. Here, the CRV operates purely on the changes in pressure within the system forming a loop that resets itself. In another embodiment, a gate valve and a vacuum canister may be included rather than having the throttle aspirator directly connected to the CRV's pneumatic control chamber.

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 method of forming a layer of material on a sidewall of a via with good thickness control. The method involves forming a layer of material with a conventional deposition process. The material formed on a field region surrounding the via is removed with a sputter etch process. Another layer of material is deposited thereon, wherein the sputter etch-deposition cycle is repeated as necessary to achieve a desired sidewall thickness. With this method, the thickness of the material deposited on the sidewall is linearly dependent on the number of process cycles, thus providing good thickness control. The method may be used to form a resistance variable material, e.g., a phase-change material, on a via sidewall for use in a memory element.

摘要： A compression release engine brake assembly adapted for use with an internal combustion engine, and an exhaust valve (29) operable to open in a normal exhaust lift event (FIG. 9) and in a brake lift event (FIG. 15). The engine includes an exhaust valve actuating mechanism (23,31,37) for imparting reciprocal movement to said exhaust valve (29) in response to rotation of a cam shaft (11) including a cam profile (13), a normal lift portion (17) and a brake lift portion (19). The assembly includes a lost motion device (75) moveable between a normal lost motion condition (FIG. 4) and an actuated condition (FIG. 14) in response to movement of an input member (91). An energy storage spring (117) is operable, after being compressed to an energy storage condition (FIG. 12) to be able to bias the input member (91) toward a second position, effecting the actuated condition of the lost motion device (75). A latching mechanism (99,103-113,129,131) is operable to first displace the energy storage spring (117) to a compressed condition, and then release it just before the cam follower (21) traverses the brake lift portion (19), in response to the pivotal movement of the rocker arm assembly (23) which comprises part of the exhaust valve actuating mechanism.
