    摘要: A two-cycle engine includes a port timing control device for varying a timing of the opening of an exhaust port by a piston. The port timing control means includes a first valve mounted within an exhaust passage adjacent to an upper end of the exhaust port and having a port timing control surface, a second valve mounted on a cylinder block between a cylinder head and the first valve and having a closure surface, and an urging member acting on the second valve to always urge it against the first valve. The first valve is operable to be angularly moved about an axis generally perpendicular to the axis of a cylinder into and out of an extended position where the control surface is disposed slightly below the upper end of the exhaust port to close a part of the exhaust port. The second valve is movable along a generally straight path into and out of an extended position where the closure surface closes that portion of the exhaust port lying between the upper end of the exhaust port and the first valve. The second valve is movable in synchronism with the angular movement of the first valve through the urging member.

    摘要: A matrix unit receives a luminance signal L* for a uniform color space and two color difference signals a* and b*. Then, when a control signal has given instructions for a mono-color editing operation, the matrix means outputs only the luminance signal L* out of the picture image data fed into it, and, when a control signal is given otherwise, the matrix means generates and outputs toner color signals for the colors Y, M, C, and K. A multiplying unit multiplies with a prescribed coefficient the picture image data which are output from the matrix unit, and the multiplying unit multiplies the picture image data with a coefficient for permitting the toner signal output from the matrix unit to pass through in case the control signal has not given any instructions for any mono-color editing operation, and multiplies the input luminance signal L* with four coefficients corresponding to the color as instructed by the control signal and generate four toner color signals for Y, M, C, and K. The coefficients have the data form representing the coverage of the toner colors, Y, M, C, and K.

    摘要: A color copying apparatus is capable of making copies without performing a prescan. Input image data of RGB format read from an image input unit is written in an image memory through the shading/gap correction unit and an input &ggr; correction unit. This input image data is supplied to a detection unit through a first color space conversion unit to distinguish color from monochrome in the input image data, and to detect the base color level and the like. Next, on the basis of these detection results, states of a second color space conversion unit, a selector, a frame-erase/base color removal unit and the like are set. Thus, the input image data is read out again from the image memory, and is supplied to an image output unit through the first color space conversion unit to an output &ggr; correction unit.
