    摘要: A mesh type automatic transmission is equipped with a plurality of shift gears arranged to rotate freely to an output shaft for providing driving force to the wheels. Cogged clutches 12, 15 engage with the output shaft. Counter shift gears corresponding to each speed are fixed to a counter shaft rotated by the rotation of an input shaft and mesh with the shift gears for performing automatic shifting by controlling engagement of one of the cogged clutches with the voluntary shift gears determined from the accelerator command value and the vehicle speed. An assist mechanism transmits rotational force of the input shaft to the output shaft via the assist shaft which rotates from the rotation of the counter shaft when no cogged clutch of the plurality of cogged clutches is engaged with any of the plurality of shift gears occurring during switching when an engaged cogged clutch of the plurality of cogged clutches is disengaged and one of the cogged clutch of the plurality of cogged clutches is to be engaged.

    摘要: An engine power train control method and control apparatus for a vehicle having an engine and an automatic transmission is capable of quickly changing an air-fuel ratio to meet the requirements for exhaust gas without producing shocks and without reducing engine torque. An air-fuel ratio command value is varied stepwise for transition between an air-fuel ratio for lean-burn operation and a stoichiometric air-fuel ratio, and at the same time, the period following the completion of the stepwise variation of the air-fuel ratio command value, a basic fuel amount fed to the engine is varied stepwise from a value determined according to the air amount and an engine speed to a value determined according to a position of an accelerator pedal of the vehicle and the engine speed. In this way, shocks do not occur and the operability is improved, because the engine torque remains substantially constant through the air-fuel ratio transition.

    摘要: An amorphous silicon conductive film on a semiconductor wafer is treated with hydrofluoric acid to remove a natural oxide film therefrom, and then a very thin oxide film is formed on the semiconductor wafer. Thereafter, a silane gas is used to form a nucleating film, followed by annealing to cause the surface of the conductive film be roughened. The very thin oxide film is formed in a thickness of 0.5 angstroms to 20 angstroms. The very thin oxide film is alternatively formed either by treatment with an aqueous hydrofluoric acid solution or by flushing treatment. Thus, a roughened surface having a satisfactory roughness is uniformly formed on the surface of a conductive film on a semiconductor wafer.

    摘要: A motion-adaptive scanning-line conversion circuit which converts part or the entirety of a first video signal into a second video signal. The circuit includes a data reducing circuit, such as a low pass filter and a decimator, which lowers the sampling frequency of the first video signal to reduce the amount of data in the first video signal. The conversion circuit can also include a detection circuit which detects the vertical edge of a stationary part of a picture represented by the reduced first video signal, and a motion detection circuit which determines the amount of motion of the pixels in the reduced first video signal. Based upon the detection of a vertical edge, a selection circuit selects between an output of an inter-field scanning-line conversion circuit and an intra-field scanning-line conversion circuit operating on the reduced first video signal and the first video signal, respectively.
