  • Patent number: 6854523
    Abstract: In a motor grader, controls for running the vehicle at a constant speed are provided when a work for improving a land surface with a blade is started by running a working vehicle at a low speed from the low idling start. With this operation, it is possible to perform the work for improving a land surface by maintaining an actual revolution speed of the engine 5 at a value obtained by subtracting a prespecified revolution speed from the revolution speed for low idling to run the working vehicle at a low speed. With this feature, it is possible to continue the work at a constant speed and also to prevent occurrence of engine stop during the work at a low speed, when a higher duty of the engine is required and the actual revolution speed drops like in the case where an ascending slope of the land to be improved becomes large or where the cutting rate temporally increases due to local irregularities of the land surface during the land surface improvement work.

  • Patent number: 6837199
    Abstract: A valve actuating apparatus for an internal combustion engine selectively operating in the normal Otto cycle or the Miller cycle is provided which enables the engine to achieve stable combustion and improved fuel economy during cruising or in a low-load engine operating region. A delayed-closing cam for Miller cycle operation and a normal cam having a cam profile for earlier valve-closing timing of the intake valve than a cam profile of the delayed-closing cam are provided on a camshaft. A cam profile-switching mechanism switches between the delayed-closing cam and the normal cam, for opening and closing the intake valve. An ECU controls the switching mechanism such that when a detected operating condition of the engine indicates starting or idling, the intake valve is operated by the normal cam, and when the detected operating condition indicates cruising, the intake valve is operated by the delayed-closing cam.

  • Publication number: 20040241685
    Abstract: An object of the present invention is to contribute to objective diagnosis of schizophrenia with use of gene expression as an index. A method to analyze in a test subject whether expression of nucleic acid(s) defining gene(s) exhibiting altered expression by schizophrenia is statistically included within the range of normal subject or not is provided by the present invention. The present method comprises the step of quantifying the amount of expression of nucleic acid(s) defining gene(s) exhibiting altered expression by schizophrenia and/or protein(s) encoded by said nucleic acid(s) defining gene(s) exhibiting altered expression by schizophrenia.

  • Patent number: 6820603
    Abstract: There is provided a control system for an internal combustion engine, which is capable of meeting a driver's demand of torque, and achieving high combustion efficiency and high emission-reducing performance by a three-way catalyst in lean-burn operation in a compatible manner. The control system sets a control amount indicative of either an oxygen mass supplied to a combustion chamber or a fuel injection amount such that oxygen concentration in exhaust gases becomes equal to a value corresponding to stoichiometric combustion. A target value corresponding to a demanded torque is set based on detected engine operating conditions. A degree of opening of a main throttle valve and a degree of opening of a sub-throttle valve in a passage by passing an intake passage equipped with a nitrogen-enriching device are controlled such that the control amount becomes equal to the set target value.
