The system has an operation state detection unit (201) and an arithmetic unit (202) to determine the desired valve control time (To) of an inlet (17) or outlet (18) valve according to the operation state (D). A variable valve timing control mechanism (40) varies the valve control time. A control unit (24) for the actual valve control time generates a control value (i) for the valve timing control mechanism. A detection unit (203) detects the actual valve control time (Ta). The control unit (24) for the actual valve control time generates a control value (i) for the valve timing control mechanism, so that the actual valve control time equals the desired valve control time. An integral control unit (205) determines an integral correction value ( EPSILON Ki) by integrating the control time to correct the control value. An initialisation use of the machine operation state is detected, to initialise the integral correction value to an optimum value, which is matched to the operation state. The initialisation unit is arranged, so that an initial value of the integral correction value is a negative value.

Valve timing control system for internal combustion engine; has units to determine desired valve control time and measure actual valve control time and control unit to correct valve timing

PROBLEM TO BE SOLVED: To provide an optical sheet capable of improving viewing angle characteristics at an end while maintaining contrast at a center part, an image display device including the optical sheet, and a manufacturing method of a sheet with improved contrast.SOLUTION: An optical sheet 10 comprises: a light transmissive base material 11; a plurality of unit light transmission parts 12a provided in parallel along a sheet surface; and a plurality of light absorption parts 13. Each light absorption part 13 includes a first end face 13a positioned on a side of the light transmissive base material 11, and a second end face 13b positioned opposite the end face 13a. The distances from the light transmissive base material 11 to the respective first end faces 13a are substantially equal to each other, and the height of the light absorption part 13 positioned at an end 10b of the optical sheet 10 is lower than that of the light absorption part 13. The optical sheet further comprises a coated part 14 that covers the second end face 13b of the light absorption part 13 positioned at least at the end 10b of the optical sheet 10, includes light transmissive resin, and has refractive index lower than that of the unit light transmission part.

PROBLEM TO BE SOLVED: To provide a slot die which is provided with a passageway that includes a transverse flow supplying manifold, a flow metering section that develops a transverse flow metering gap and an exit channel that includes an exit orifice. SOLUTION: When a slot die is in a first condition, the second die body and the third die body are non-adjustable, and when the slot die is in the second condition, the second die body and the third die body keep the position adjustable. Each has a moving shaft which determines a Z-axis of an X-Y-Z coordination system. The transverse flow metering gap of the flow metering section can be adjustable independently of the change in the gap of the exit orifice by moving at least one of the position adjustable die bodies along the Z-axis. The transverse flow metering gap can be selected independently of the change in gap or width of the gap of the exit orifice by using one or more of the die body which is normally non-adjustable.
