Abstract: An electrophotographic color image forming machine registers which a second color toner image on a first color toner image which has been previously formed on an image carrier to form a color image. The registered images are then transferred onto a recording sheet. The machine includes control apparatus that includes first and second exposure control modulators which respectively control an exposure amount of at least one of the first color toner images and the second color toner image. A smoothing processor controls at least one of a size and a position of at least one of the first and second color toner dot images within each of a plurality of pixels and a discriminator determines whether one of the size and the position of the dot image should be controlled.

Abstract: The safety net is adapted to be mounted in a motor vehicle such as a stationwagon, van or the like, to separate a passenger compartment in the motor vehicle from a cargo compartment and prevent injury to passengers in the passenger compartment upon abrupt deceleration of the vehicle, for example due to a frontal collision or the like, by preventing flying objects such as suitcases (9) from reaching the passenger compartment. To prevent tearing of the net if the body of the vehicle is deformed so that the net, stretched between the roof and the backseat or bottom of the cargo compartment, is excessively stressed, the net is formed with a tear prevention arrangement which includes a net size expansion compensation arrangement (17) in the form of a fold, for example a zig-zag fold, seamed into the net and held in position by a frangible, stitched seam line (31, 34), which can tear upon substantial stresses placed on the net.

Abstract: In an imaging apparatus capable of expanding a dynamic range image signals of different levels are read simultaneously from a solid-state element whose light-receiving surface is divided. Read 1/2 frame image signals are switched by a changeover switch circuit at intervals of a 1/2 frame time. One of two image signals of different levels supplied from the two outputs of the changeover switch circuit is delayed at a delay circuit. Further, those image signals are separated into r, g, and b components, and then undergo logarithmic conversion into image signals of multiple desired levels. The signals are digitized at an A/D converter and undergo operations at an adder, which adds while keeping their logarithmic characteristic, and at an inverse logarithmic converter. A luminance signal is obtained at a matrix circuit, and is converted into a logarithm at a logarithmic circuit. The lighting irregularity components of the resulting signal are suppressed.
