    • To facilitate the adjustment of the accuracy and servicing maintenance of the electronic weighing apparatus, the weighing apparatus comprises a load cell and a signal processing circuit for processing a load signal from the load cell to provide a weight signal indicative of the load. The load cell includes a strain inducing element capable of producing strains in proportion to the load imposed thereon, and a bridge circuit, having a pair of strain gauges fixed on the stain inducing element and a plurality of resistors. A load signal is taken from a junction between the strain gauges and reference voltage signals are taken from junctions between the resistors. The load signal and the reference voltage signals are supplied to the signal processing circuit. If each of the strain gauges is employed in the form of a temperature compensating resistor having a characteristic effective to compensate for both of the temperature coefficient of thermal expansion of the strain inducing element and the temperature coefficient of the Young's modulus, the number of necessary component parts can be reduced.
    • 为了便于电子称重装置的精度和维修维护的调整,称重装置包括负载传感器和信号处理电路,用于处理来自称重传感器的负载信号,以提供指示负载的加权信号。 负载传感器包括能够产生与施加在其上的负载成比例的应变诱发元件,以及桥接电​​路,其具有固定在污染诱导元件上的一对应变计和多个电阻器。 负载信号取自应变计之间的接点,参考电压信号取自电阻之间的结。 负载信号和参考电压信号被提供给信号处理电路。 如果每个应变计采用温度补偿电阻器的形式,其具有有效补偿应变诱发元件的温度系数和杨氏模量的温度系数的特性,必要部件的数量 零件可以减少。

    • A photodetector capable of improving dynamic range for input signals is provided. This photodetector includes a photoelectric converting portion, a charge separating portion, a charge accumulating portion, a barrier electrode formed the charge separating portion and the charge accumulating portion, and a barrier-height adjusting portion electrically connected to the barrier electrode. Undesired electric charges such as generated when environment light is incident on the photoelectric converting portion are removed by the charge separating portion. A potential barrier with an appropriate height is formed under the barrier electrode by applying a voltage to the barrier electrode according to an electric charge amount supplied from the charge separating portion to the barrier-height adjusting portion. Electric charges flowing from the charge separating portion into the charge accumulating portion over the potential barrier are provided as an output of the photodetector.
