    • A method and apparatus for counting nominally identical articles employs weighing apparatus, which comprises a load hod (102) for holding a number of articles to be weighed and a load transducer (20) responsive to loading of the hod (102) to produce a derived electrical signal indicative of the apparent weight of articles in the hod (102). The signal is susceptible to fluctuation as a result of local air currents acting on the hod (102) or on the articles contained therein. The transducer derived signal is filtered to extract a component signal representative of such fluctuation. After further processing, the filtered component signal is used to correct the original transducer signal thereby to indicate the true weight of articles in the hod (102). The number of articles in the hod (102) is then determined by dividing the true weight indication by an expected average weight of an article. Fluctuations in the transducer signal due to air currents may also be removed by a system of validation of the signals depending on whether or not they are within range limits based on a running average.
    • 用于计数名义上相同的制品的方法和装置使用称重装置,其包括用于保持多个待称重物品的装载架(102)和响应于所述炉(102)的装载产生衍生的 电信号,表示物品(102)中物品的表观重量。 由于局部气流作用在炉体(102)或其上所含的物品上,该信号容易发生波动。 对换能器导出信号进行滤波以提取代表这种波动的分量信号。 在进一步处理之后,滤波后的分量信号用于校正原始换能器信号,从而指示炉头(102)中物品的真实重量。 然后通过将真实重量指示除以物品的预期平均重量来确定盘(102)中的物品数量。 由于气流引起的传感器信号的波动也可以通过信号的验证系统去除,这取决于它们是否在基于运行平均值的范围限度内。

    • In order to determine the dielectric constant of a layer deposited on a semiconductor wafer (2), the density of the layer is obtained. To obtain that density, the wafer (2) without the layer is weighed in a weighing chamber (4) in which a weighing pan (7) supports the wafer on a weighing balance. The weight of the wafer is determined taking into account the buoyancy exerted by the air on the wafer (2). Then the layer is deposited on the wafer (2) and the weighing operation repeated. Alternatively a reference wafer may be used. If the material of the layer is known, the weight of the layer can be used to derive its density using a thickness measurement. Alternatively, if the density is known, the thickness can be obtained.
    • 为了确定沉积在半导体晶片(2)上的层的介电常数,获得了该层的密度。 为了获得该密度,在称重室(4)中称量没有层的晶片(2),其中称重盘(7)在称重平衡面上支撑晶片。 考虑到空气对晶片(2)施加的浮力来确定晶片的重量。 然后将该层沉积在晶片(2)上,重复称重操作。 或者,可以使用参考晶片。 如果层的材料是已知的,则可以使用层的重量来使用厚度测量来获得其密度。 或者,如果密度是已知的,则可以获得厚度。

    • A feed metering device for distributing fodder and/or drink in metered portions to an animal. The feed metering device is provided with a feed unit for containing fodder and/or drink, an entrance opening to the feed unit, and a feed supplying device for supplying an amount of fodder and/or drink to the feed unit. The feed metering device is provided with a closing means that is movable across the entrance opening in order to deter an animal visiting the feed unit from taking fodder and/or drink. The closing means rotates about an axis, the closing means being driven by a roll that contacts the closing means, which roll is driven by a motor.
