20110049272 | FUEL INJECTOR - A fuel injector comprising a valve needle for controlling fuel injection through an injector outlet, a control chamber for receiving fuel and a three-way control valve that controls fuel pressure within the control chamber to control opening and closing movement of the valve needle to control fuel injection through the outlet. The three-way control valve controls communication between (a) a first passage and a second passage and (b) a third passage and the second passage, and includes a first housing provided with a guide bore for a control valve member, whereby movement of the control valve member is guided within the guide bore and a first valve seat, defined by a second housing, with which an end of the control valve member is engageable to control communication between the first and second passages. The first housing is a control valve housing and the second housing is an injector housing, the injector housing being provided with a guide bore for the valve needle or a part carried by the valve needle. The control valve also defines a second valve seat defined by the first housing with which the control valve member is engageable to control communication between the second and third flow passages, and an intermediate housing located between the first and second housings, wherein the second passage is defined within the intermediate housing. | 03-03-2011 |

20090020633 | Spray hole profile - A fuel injector for an internal combustion engine comprising a nozzle body having at least one spray hole. The at least one spray hole has a hole entry on the inside of the nozzle body and a hole exit on the outside of the nozzle body. The spray hole is provided with a hole entry section which, starting from the hole entry, has a flow area which decreases from a relatively larger flow area at the hole entry to a relatively small flow area at the intersection between the end of the hole entry section and the start of a hole exit section. The hole exit section, starting from the intersection with the hole entry section, has a flow area which increases from a relatively small flow area at the intersection with the hole entry section to a relatively larger flow area at the hole exit. | 01-22-2009 |

20080272214 | Fuel injector - A fuel injector comprising a nozzle having a nozzle needle which is moveable with respect to a first needle seat to control fuel delivery through a nozzle outlet. The injector includes a nozzle control valve for controlling fuel flow into a control chamber through a first passage to pressurise the control chamber, and for controlling fuel flow out of said control chamber through said first passage to depressurise the control chamber. Movement of the nozzle needle is controlled by fuel pressure within the control chamber, such that pressurising the control chamber causes the nozzle needle to be urged against the first needle seat to close the nozzle outlet, and depressurising the control chamber causes the nozzle needle to lift from the first needle seat to open the nozzle outlet. The nozzle needle defines, at least in part, a restricted passage through which fuel can flow into the control chamber as the control chamber depressurises. The fuel flow into the control chamber through the restricted passage serves to reduce the rate at which the control chamber depressurises, thereby reducing the rate at which the nozzle needle lifts from the first needle seat to open the nozzle outlet. | 11-06-2008 |

20100128394 | TOP BOND PAD BIAS AND VARIATION CONTROL - An assembly includes a slider and a suspension assembly. The slider includes an air bearing surface and a slider mounting surface opposite the air bearing surface. There are a plurality of slider pads on the slider mounting surface. The suspension assembly includes a plurality of suspension pads on a suspension mounting surface. Each of the suspension pads is connected to one of the slider pads with a solder joint so that the slider mounting surface has at least one of a pitch, roll, or yaw angle with respect to the suspension mounting. | 05-27-2010 |

20110156916 | Nuclear radiation-warning detector that measures impedance - Disclosed is a nuclear radiation-warning detector that measures impedance of silver-silver halide on an interdigitated electrode to detect light or radiation comprised of alpha particles, beta particles, gamma rays, X rays, and/or neutrons. The detector is comprised of an interdigitated electrode covered by a layer of silver halide. After exposure to alpha particles, beta particles, X rays, gamma rays, neutron radiation, or light, the silver halide is reduced to silver in the presence of a reducing solution. The change from the high electrical resistance (impedance) of silver halide to the low resistance of silver provides the radiation warning that detected radiation levels exceed a predetermined radiation dose threshold. | 06-30-2011 |
