摘要： In a top scale balance which has a Roberval's chain 10 and a load weight transmitting lever 30 and in which a movable post 13 of the Roberval's chain 10 is connected to a point of force 32 of the lever 30 through an elastic connection fulcrum 51, a horizontal member 12 nearer to the elastic connection fulcrum 51, out of upper and lower horizontal members 11, 12 of the Roberval's chain 10, is greater in rigidity than the other horizontal member 11. Alternately, the upper and lower horizontal members 11, 12 are equal in rigidity and the elastic connection fulcrum 51 is positioned, in the vertical direction, at the center between the upper and lower horizontal members 11, 12. Such an arrangement prevents or reduces the movement of the elastic connection fulcrum 51 in the back-and-forth direction due to an offset placed load. Thus, even though the top scale balance is made in a compact and thin design with the lever ratio increased, the top scale balance is high in precision with a less offset position error.

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： An electronic balance includes a load transmission mechanism for receiving an object to be measured, a magnetic field generator having a force coil for generating magnetic field, and a balance beam connected at one end to the load transmission mechanism and disposed adjacent to the magnetic field generator with a fulcrum interposed between a portion connected to the weight section and the magnetic field generator. An electromagnetic force generated by supplying current to the force coil is applied to the balance beam to obtain a weight of the object from the current flowing through the force coil in equilibrium with the load. A damper is attached to the balance beam to control vibration in at least one of a longitudinal direction of the balance beam and a horizontal direction perpendicularly intersecting therewith.

摘要： A floor portion separates a weighing chamber encircled by a windshield case and accommodating a weighing pan, and a balance body accommodating a load detecting section, an incorporated weight, etc. A plurality of vents is provided through the floor portion. A movable floor is arranged to be able to move back and forth on supporting members. A plurality of vents is provided through the movable floor on the rear side of the floor portion so that number and center position of the vents of the movable floor is the same as the vents of the floor portion. When a temperature difference between the temperatures within the weighing chamber and within the balance body is large, the movable floor is moved to permit airflow between the weighing chamber and the balance body.
