摘要： By using a second Roberval mechanism having beams orthogonal to beams of a first Roberval mechanism for supporting a weighing dish by a movable pillar and integrating a movable pillar of the second Roberval mechanism with a movable pillar of the first Roberval mechanism, longitudinal and crosswise one-sided loads are shouldered by first and second Roberval mechanisms and. Furthermore, by forming flexible portions flexible for one-sided loads (right and left one-sided loads) about the axis of the first Roberval mechanism on the first Roberval mechanism, torsions due to one-sided loads in the crosswise directions are prevented and influences of the torsions can be reduced. Moreover, by forming flexible portions flexible for a longitudinal one-sided load on the second Roberval mechanism, a torsion due to the longitudinal one-sided load is prevented and influences of the torsion can be reduced.

摘要： An electronic balance devised so that the weighing pan of the balance may settle down fast to make the balance indicate a correct value of measurement quickly without being long disturbed by the air turbulence arising when the door of the weighing pan protecting chamber of the balance is opened and continuing for a while after the door has been closed. This electronic balance is provided witha heater on the base portion of the weighing pan protecting chamber so that the heater is located just below the door of the chamber. The heater generates hot air streams rising upward therefrom along the outer surface of the door. When the door is opened, the air streams play a role of an air curtain to prevent a possible air exchange between the hotter chamber warmed by the electronic circuit of the balance and the cooler surrounding atmosphere.

摘要： There is disclosed a weighing scale in which a non-Roberval type load cell is used to detect a weight to be measured. The load cell used consists of two parallel cantilevers with the free ends connected to each other through a connecting means and of four strain gauges applied to the cantilevers by sticking every two of the four strain gauges on two separate positions in the longitudinal direction of each of the cantilevers. The four strain gauges constitute a bridge circuit which outputs the weight value of a weight placed on a weighing tray connected to the two cantilevers so that the center of the tray is positioned above the center of the plane made by the two cantilevers. According to this invention the weighing errors due to an eccentric or uneven weight loading on the tray are automatically eliminated on account of the structural symmetry of the load cell used. The difficulties in manufacturing a Roberval type precision load cell have finally be put out of the way by the present invention.
