Abstract: A load sensor includes a scale cell for producing an output signal corresponding to the weight of an article, and a dummy cell, provided near the scale cell, for producing a noise signal output ascribable to floor vibration. A correcting circuit extracts a signal proportional to a DC component contained in the output signal of the scale cell and, on the basis of the extracted signal, corrects the output signal of the dummy cell to the noise level of a floor vibration component of the scale cell. The corrected dummy cell noise signal is added in opposite-phase relation to the scale cell output signal, so that the floor vibration noise contained in the scale cell output signal is cancelled out by the corrected noise signal of the dummy cell.

Abstract: A load sensor includes a fixed rigid portion, a movable rigid portion spaced from the fixed rigid portion and adapted to receive an applied load, and a shear-deformable member provided between the two rigid portions. The shear-deformable portion is provided with a transmission and a reception transducer constituting an elastic surface-wave oscillator. When a load is applied to the movable rigid portion, weight is sensed based on a deviation in the oscillation frequency of the elastic surface-wave oscillator. The fixed and movable rigid portions, as well as upper and lower beams interconnecting these portions, constitute a load-sensitive element. The latter has a side face which is closed off by a pliable membrane for sealing the shear-deformable element disposed within the load-sensitivie element. Alternatively, a corrugated bellows is connected across the fixed and movable rigid portions to seal the shear-deformable member within the bellows.

Abstract: A double-integrating A/D converter in which an integrator output voltage, produced by integrating an analog signal input thereto, is reverse-integrated in accordance with a reference voltage having a polarity opposite to that of the analog signal. The time required for the reverse integration is measured in the form of a pulse count by means of a counter. A microcomputer for controlling the counter and a switch which selects the input to the integrator are provided with a software timer function so that the integrating interval of the analog input signal is set at will. The microcomputer also is capable of calculating a digital value, which corresponds to the analog signal, from a count recorded in the counter and from an overflow value indicated by an overflow signal generated by the counter. The signal converted by the A/D converter is capable of being applied to the weighing section of an electronic weigher.

Abstract: A combinatorial weighing system for combinatorially weighing articles by obtaining an optimum combination of weight values produced by a plurality of weighing machines each of which contains a supply of the articles. The system includes a circuit for detecting a malfunction in any of the weighing machines, and a circuit for excluding weighing machines, detected as having malfunctioned, from participation in combinatorial weighing, and for executing combinatorial weighing using weighing machines other than the excluded weighing machine. When the number of excluded weighing machines exceeds a predetermined number, however, the weighing operation is halted. Even if several of the weighing machines malfunction, therefore, operation is allowed to continue, without terminating the overall weighing operation.
