Abstract: PURPOSE:To enable the filling of a product with a weight thereof closer to a target weight value than conventional one by counting a frequency of occurrence of a pulse signal until a weighing signal of a weighing device exceeds a quantitative cut weight from the start of operation of a feeder. CONSTITUTION:A pulse generator 6 is provided to generate a pulse signal as a feeder 5 feeds a product by a fixed volume and a frequency of occurrence of the pulse signal is counted until a weighing signal of a measuring device 10 exceeds a quantitative cut weight from the start of operation of the device 4.

Abstract: PURPOSE:To make it possible to obtain a uniform image by a simple circuit and an image memory with small capacity, by calculating vector components in the x-direction and y-direction of the tangential line at the arbitrary point on an imaginary circle with a predetermined radius and comparing the magnitudes thereof. CONSTITUTION:Vector components in the x-directions and y-directions of tangen tial lines at arbitrary points, for example, P1, P2 on an imaginary circle C0 with a predetermined radius and the magnitudes thereof are compared with each other. As a result, when the x-direction vector components are smaller than the y-direction vector components, that is, the angle formed by the point P1 on the imaginary circle C0 and the x-axis is between 0 deg.-45 deg., lattice points of picture elements are set on the basis of the lattice points in the x-direction so that image data stored like 1, 2, 3 have predetermined widths in the y- direction. By successively setting image lattice points over the entire imaginary circle C0 as mentioned above, image data based on an ultrasonic echo are radial ly written. By this method, the uniformity and smoothness of image data gener ate no difference in a scanning line direction and a scanning line number direc tion.
