  • Patent number: 7681522
    Abstract: The present invention provides an apparatus for manufacturing a bonded substrate that suppresses a defect in the bonded substrate. When the pressure in a vacuum chamber is at the atmospheric level, upper and lower chuck units respectively attract substrates through vacuum. When the vacuum chamber is depressurized, each chuck unit electrostatically attracts the associated substrate. During the depressurization of the vacuum chamber, the pressure for attracting each substrate to the associated chuck unit is controlled to be equal to the pressure in the vacuum chamber. This prevents each substrate from falling from or moving relative to the associated chuck unit. The first and second substrates are thus bonded together and accurately aligned.

  • Patent number: 7681545
    Abstract: An idling stop control of the invention attains an auto start and an auto stop of an engine. At a time point t1, pre-set stop conditions are met to cut off a fuel supply to the engine. Preset starting conditions may be met at a time point t2 when the engine still continues rotating in a normal direction by the inertial force. In this state, the idling stop control starts cranking the engine. The preset starting conditions may be met at a time point t4 when a piston does not complete a compression cycle immediately before a stop of the engine but is pressed back by the compressed air to rotate the engine in a reverse direction. In this state, the idling stop control waits until cancellation of the reverse rotation of the engine and then starts cranking the engine. The arrangement of the invention desirably ensures a quick start of the engine, while effectively preventing an excess stress from acting on a gear mechanism, which connects a starter motor to the engine.

  • Patent number: 7681550
    Abstract: An internal combustion engine 10 includes a fuel injection valve 37 for injecting a gasoline fuel into a combustion chamber 25, and a spark plug 35. When the internal combustion engine is operated in a light-load region, the fuel is injected at an early and/or middle stage of an intake strode, whereby a homogeneous air/fuel mixture is formed and compressed to thereby perform a premixed-charge compression auto-ignition operation in which the fuel is auto-ignited and combusted. When the internal combustion engine is operated in a middle-load region, a spark-ignition combustion operation is performed. When the internal combustion engine is operated in a high-load region, air taken into the combustion chamber is compressed, and the fuel is injected into the compressed air, thereby performing a diffusion combustion operation in which the fuel is diffusion-combusted.

  • Patent number: 7681560
    Abstract: The present invention prevents an EGR sensor installed in an engine's EGR path from being soiled by soiling substances in exhaust. A catalyst is positioned upstream of the EGR sensor to purify the soiling substances in EGR gas. The status of the EGR sensor is properly controlled in accordance with the conditions of the catalyst. This ensures the EGR sensor is less likely to be affected by the soiling substances in the exhaust under any circumstances of the EGR path and allows the EGR sensor to avoid a decrease in the accuracy of EGR gas detection. An alternative configuration may be employed such that the EGR gas recirculates from the downstream side of a catalyst installed in a main exhaust path.
