    摘要： Texture data which is two-dimensional image data indicating color data of multiple pixels positioned in a matrix form is stored in a texture buffer of a DRAM, a texture engine circuit combines the bit data making up the U address of a two-dimensional address (U, V) represented by n bits (wherein n is an integer of 1 or greater) and the bit data making up the V address of the two-dimensional address (U, V) represented by m bits (wherein m is an integer of 1 or greater), thereby generating an (n+m)-bit one-dimensional address, and the generated one-dimensional address is used to access the storage circuit. Accordingly, the storage area of the texture buffer can be used efficiently with a small circuit configuration.

    摘要： A semiconductor angular velocity sensor has a frame-shaped base portion, a detection oscillator connected to the base portion through a detection beam portion, and a drive oscillator connected to the detection oscillator through a drive beam portion. Each of the beam portions has a pair of beams each generally having a U shape and connected to each other through a bridge portion. Accordingly, the beam portions can have large rotational rigidity not to prevent oscillations of the oscillators.

    摘要： An internal combustion engine that is comprised of a combustion chamber formed by a cylinder bore closed at one end by a cylinder head and by a piston reciprocating in the cylinder bore. At least one intake passage serves the combustion chamber through an intake port valved by an intake valve. A throttle valve is provided in the intake passage upstream of the intake port and is movable between an opened, full throttle position and a closed, idle position for controlling the flow through the intake passage into the combustion chamber. At least one exhaust passage serves the combustion chamber through an exhaust port. An exhaust valve controls the flow through the exhaust port. Valve actuating means are provided for operating the intake valve and the exhaust valve between their open and closed positions. The portion of the intake passage between the throttle valve and the intake port (intake passage volume) and the maximum volume of the combustion chamber when the piston is at its bottom dead center position (exhaust gas volume) are set to a predetermined ratio. The described constructions permit a very compact construction that permits the intake passage volume to be kept small to achieve the desired ratio.

    摘要： An improved feedback control system for an engine that employs only a single sensor associated with only one cylinder of the engine. Cylinder-to-cylinder adjustments are made based upon measurement of the differences in crankshaft speed during a portion of the compression stroke for each cylinder so as to provide an accurate indication of air flow to the individual cylinders.
