    • A dispersion feeder for distributively feeding product to a plurality of weighing units arranged circularly about a common axis, comprising a plurality of conveyer troughs arranged radially about the axis for communicating by their outer ends respectively with the weighing units, and a plurality of vibrating units attached respectively to the conveyer troughs for subjecting each conveyer trough to independent vibration. Each conveyer trough is provided with a projection inclined upwardly and radially inwardly toward the common axis. These projections are arranged radially about the axis without mutual contact to form a conical or domed substantially continuous central dispersion surface, and each projection and its corresponding conveyor trough is adapted to be subjected to independent vibration to feed product supplied directly onto the dispersion surface to the corresponding conveyer trough.

    • The invention is intended to enable the easy measurement of the amount of color purity at each of many measured points. An adjusting coil (9) is provided at a neck portion of a color cathode ray tube (1). Also, a color image pickup means (4) for photographing the screen of the color cathode ray tube (1) is provided. A monochrome signal of any one of red, green, and blue colors is input to this color cathode ray tube (1). Thereafter, while varying the electric current made to flow through the adjusting coil (9), the image pickup signal obtained by the color pickup means (4) is decomposed into red, green, and blue color signal components; and the intensity of each of them is measured. Then, using the values of the electric currents that are supplied to the coil adjusting (9) and the location distances between the luminous regions of the red, green, and blue colors on the color cathode ray tube (1), there is determined the following: the amount of movement of the relevant electron beam with respect to the unit value of electric current for the adjusting coil (9). Thereby, it is arranged that the amount of color purity at the measured point is obtained according to the amount of movement of the relevant electron beam with respect to the unit value of electric current for the adjusting coil (9).
