    摘要： A method of this invention is applied to a nonvolatile memory device composed of first memory cells connected to one of a first word-line pair and second memory cells connected to the other of the first word-line pair, and a single source shared by the first memory cells and the second memory cells. First, a positive potential of, for example, 5 V is applied to the source, a negative potential of, for example, -10 V is applied to the one of the word-line pair, and the ground potential to the other of the word-line pair. This permits electrons to move from the floating gate of the first memory cells into the source, with the result that the erasing of information is achieved. Next, the positive potential is applied to the source, the negative potential is applied to the other of the word-line pair, and the ground potential to the one of the word-line pair. This permits electrons to move from the floating gates of the second memory cells into the source, with the result that the erasing of information is achieved.

    摘要： A control system for a combinatorial weighing or counting apparatus includes a main central processing unit for effecting a combinatorial arithmetic operation, and a plurality of individual drive unit central processing units. The drive unit central processing units are associated respectively with driver units of the weighing machines and connected to the main central processing unit for controlling the drive units, respectively. Operation commands delivered from the main central processing unit to the individual drive unit central processing units, are set by interrupt processes of the individual drive unit central processing units at all times.The control system for the combinatorial weighing or counting apparatus includes a main computer for chiefly effecting a combinatorial arithmetic operation on weight data from a plurality of the weighing machines to select a combination of weighing machines including articles having an optimum added value with respect to a target value. The control system also includes other computers for controlling auxiliary operations such as a supply of articles to the weighing machines or a discharge of the articles therefrom; thus each of the main computer and the other computers carries out its own share of processing functions.

    摘要： A combinatorial weighing method which includes steps of dividing a target weight value, set for articles which are to be weighed out, into a plurality of target values, and executing combinatorial computations with respect to each of the target values on the basis of the weight values of the articles fed into a number of weighing machines, so that weighing hoppers selected with respect to each target value do not include weighing machines selected with respect to the other target values. An error between the total weight value of the combination of articles selected as a result of the previous combinatorial computations and the target value for that particular combinatorial computation is formed. The error is added to the target value for the next combinatorial computation and then the next combinatorial computation is executed. After completing the combinatorial computations with respect to all of the target values, the articles are discharged from the selected weighing machines.
