20100043747 | FUEL INJECTION SYSTEM OF COMPRESSION IGNITION INTERNAL COMBUSTION ENGINE - An object of the present invention is to control the discharge amount of unburned fuel components in the internal combustion engine. According the present invention, the number of times of execution of sub fuel injection is changed based on the operation range within which the operation state of the internal combustion engine falls so that the lower the engine load of the internal combustion engine is, and the lower the number of engine revolutions of the internal combustion engine is, the more the number of times of execution of sub fuel injection is increased. Furthermore, the lower the atmospheric pressure is, the lower the temperature of the cooling water of the internal combustion engine is, or the lower the temperature of the intake air of the internal combustion engine is, the more an operation range in which the number of times of execution of sub fuel injection is large is expanded to higher loads and higher revolutions. | 02-25-2010 |
20100211293 | INTERNAL COMBUSTION ENGINE EXHAUST GAS SYSTEM AND CONTROL METHOD OF THE SAME - An internal combustion engine exhaust gas system includes a filter arranged in an exhaust passage of the internal combustion engine, a fuel adding valve which is arranged upstream of the filter and supplies fuel into the exhaust passage, and a low-pressure exhaust gas recirculation apparatus that removes some of the exhaust gas from downstream of the filter as EGR gas. An EGR rate is controlled taking into account the amount of fuel supplied by the fuel adding valve such that an oxygen concentration of intake gas, which is drawn into a cylinder of the internal combustion engine in a state in which the EGR gas that is introduced by the low-pressure exhaust gas recirculation apparatus is mixed with air introduced into an intake passage, is constant before and after fuel is supplied by the fuel adding valve. | 08-19-2010 |

The status data acquiring unit acquires status data from the electrical equipment via the communication unit. The display unit displays the fixed data and the customized data. The fixed data and the customized data are in association with the status data acquired by the status data acquiring unit. | 04-01-2010 |
20120204087 | Document Clipping with Linked Information - An apparatus receives a first selection command to select a part of an area of a displayed first document (e.g., text, image, etc) as a selected area. When the apparatus receives the first selection command, the apparatus causes display content included in the selected area selected in response to the first selection command to be stored in a storage unit and determines whether link information linked to second document is included in the selected area. The apparatus acquires document data of the second document using the link information in response to determining that the link information is included in the selected area. | 08-09-2012 |

20100033288 | Thin inductor, method of producing the thin inductor, and ultra small size power conversion apparatus using the thin inductor - Two coil conductors of the same spiral shape are cut out from a lead frame. The two coil conductors are disposed back to back so that the front of a first coil conductor is superimposed over the rear of a second coil conductor. Central end portions of the first and second coil conductors are connected to each other through a connection layer. Outer end portions of the spirals of the first and second coil conductors are connected to corresponding ones of first and second terminals of the thin inductor, respectively. A sintered green sheet as a magnetic substance is disposed in gaps between the first and second coil conductors. In this manner, the invention can provide a thin inductor small in size, strong in mechanical strength and inexpensive, a method of producing the thin inductor, and an ultra small size power conversion apparatus using the thin inductor. | 02-11-2010 |

20090159048 | Injected Fuel Pressure Boosting Device - An injected fuel pressure boosting device provided with a large diameter piston, a medium diameter piston, and a small diameter piston. A high pressure chamber filled at high pressure at all times is formed at the outer end of the medium diameter pistons, while a pressure boosting chamber is formed at the outer end of the small diameter piston. A pressure control chamber is formed on the end face of the large diameter piston on the small diameter piston side. When high pressure fuel is supplied to the pressure control chamber, the large diameter piston moves to the medium diameter piston side, that is, the pressure boosting preparation position. At this time, the leaked fuel outflow port is closed by the end face of the large diameter piston. | 06-25-2009 |

20090029826 | Controller of work vehicle - Various works of a tractor or wheel loader that require frequent operations of start, stop, and switching between the forward drive and reverse drive that are repeated alternately can be performed very easily. The control apparatus comprises a speed change sensor that detects the step-on amount of a speed change pedal, an actuator that regulates the swash plate angle of a hydraulic pump based on the detection value of the speed change sensor, a transmission output unit rotation sensor that detects the revolution speed of an output shaft, and a control unit. The control unit performs control such that when the speed change pedal is not stepped on, a brake is applied to the travel wheels and both the forward drive clutch and the reverse drive clutch are disengaged, and also performs control such that when the transmission drive output detected with the transmission output unit rotation sensor is not more than that the forward-reverse drive switching speed, either the forward drive clutch or the reverse drive clutch is engaged as the speed change pedal is stepped on. When the engagement of the forward drive clutch or reverse drive clutch is confirmed, the brake of the travel wheels is released. | 01-29-2009 |
