  • Patent number: 8620561
    Abstract: A control for an internal combustion engine having a fuel injection valve for directly injecting fuel to a combustion chamber of the engine, an ignition device for burning an air-fuel mixture containing the fuel injected from the fuel injection valve, and a variable cylinder management mechanism that is capable of changing the number of operating cylinders is provided. The control includes making a transition to an operating mode where the number of operating cylinders is decreased through the variable cylinder management mechanism. It is predicted based on an operating condition of the engine that an air-fuel ratio of an exhaust atmosphere of the engine becomes lean due to a stop of the fuel injection into one or more cylinders to be halted by the transition.

  • Publication number: 20120252143
    Abstract: To solve a problem that, in a method of manufacturing an organic light emitting device using a step of releasing a layer formed on a release layer by dissolving the release layer, released film flakes are not dissolved in a removing liquid for dissolving the release layer, and thus may drift in the removing liquid and may adhere to a surface of a substrate after patterning to cause defective patterning, provided is a method of manufacturing an organic light emitting device, including forming the release layer continuously over multiple light emitting portions to cause the size of the released film flakes to be large. This may reduce the possibility that the released film flakes adhere to the surface of the substrate and may facilitate, even when the released film flakes once adhere to the surface of the substrate, removal of the released film flakes later, thereby suppressing defective patterning.
