Claims Analysis
Total Claims: 16
Claim 1
Independent Claim
85 words
A weighing machine wherein a load cell (7) having at one side thereof a support (8') for supporting a weighing member (9') is connected at the other end thereof to another support (5') which is supported on a frame (2) through an elastic body, the improvement in that said load cell (7) being connected at the other side thereof to said frame (2) through an anti-vibration damper (12) and a strain generator (3', 29) being arranged between said frame (2) and said other support (5').
Claim 2
Dependent Claim
85 words
A weighing machine wherein a load cell (7) having at one side thereof a support (8') for supporting a weighing member (9') is connected at the other end thereof to another support (5') which is supported on a frame (2) through an elastic body, the improvement in that said load cell (7) being connected at the other side thereof to said frame (2) through an anti-vibration damper (12) and a strain generator (3', 29) being arranged between said frame (2) and said other support (5').
Claim 3
Dependent Claim
16 words
A weighing machine according to claim 1, wherein said anti-vibration damper being an anti-vibration rubber (12).
Claim 4
Dependent Claim
18 words
A weighing machine according to claim 1 or 2, wherein said strain generator being leaf springs (3', 3').
Claim 5
Dependent Claim
58 words
A weighing machine according to anyone of the preceding claims, wherein a dummy load cell (7') separate from said load cell (7) is attached to said other support (5'), said dummy load cell (7') being spaced from said load cell (7) and having a dummy mass (15) to have the same natural frequency as said load cell (7).
Claim 6
Dependent Claim
34 words
A weighing machine according to claim 4, wherein said dummy mass (15) being provided on a support in frame holes (16) formed in both said load cell (7) and said dummy load cell (7').
Claim 7
Dependent Claim
25 words
A weighing machine according to anyone of claims 4 and 5, wherein said dummy mass (15) being exchangeable with respect to said dummy cell (7').
Claim 8
Dependent Claim
34 words
A weighing machine according to claim 1, wherein said load cell (7) being connected to said frame (2) through a metal-made strain generator (29) and supported on said frame through an anti-vibration damper (33).
Claim 9
Dependent Claim
51 words
A weighing machine according to claim 7, wherein a dummy cell (7') having the same natural frequency as said load cell (7) being additionally provided, said dummy cell (7') being connected to said frame (2) through a metal-made strain generator (29) and supported on said frame through an anti-vibration damper (33).
