    摘要: A weighing balance to provide an average weight to an object which tends to move while being weighed such as a laboratory animal. The object to be weighed is placed on a receiving pan which provides an electrical analog output signal corresponding to the weight of the object. This signal after passing through an amplifier is converted to a digital electrical signal fed to a data input control means. A level detector setting means allows an output from said control means only when the weight on the balance reaches a predetermined level. The output from the control means is fed to a memory having a plurality of registers which store this information. Coupled on one side to this memory is a comparator which is also coupled on a second side to said control means. Also coupled to said comparator means is an allowable range means, sampling time means, and average calculating means. The average calculating means feeds an output to a printer.

    摘要: There is disclosed an electronic counting scale provided with means for calculating a maximum addable number of items to be added to an already counted known number of items with an error being eliminated from the counted number of a total items including the added items, said means calculating the maximum addable number on the basis of the standard variation of an average weight estimated from the samples taken from the entire population of the items to be counted.

    摘要: An electronic balance which displays a correct weight value by averaging the digitized weight data outputted at predetermined time intervals from a weight detector provided in the balance. The weight data averaging to give a correct value is carried out with the number of the basis data for averaging increased each time a new weight data is obtained, after the weight data, which are largely fluctuating in the beginning, have been considered to be stabilized by being settled down in a predetermined limit. In case the once stabilized weight data are brought back into a fluctuating state owing to any external disturbance, such fluctuation is detected and the again unstabilized weight data are excluded from the averaging to give a correct weight value.
