Title: Weighing apparatus
Inventor: YAMANAKA MASAMI
IPC: G01G23/37
Filed: 1986-05-07
Abstract: PURPOSE:To enable an accurate measurement even though the natural vibration of a weighing unit is not sufficiently damped by calculating the time width of one period of the natural vibration of the weighing unit or integer times the time width on the basis of the weight data of an object to be weighed. CONSTITUTION:An integrator 4 integrates analog signals indicative of the weight of an object 2 to be weighed by the time width or the integer times the time width of the natural vibration period of a weighing unit 1 calculated from a measurement result. The output of an arithmetic unit 8 is delivered to the integrator 4 and a divider 5 via a delay circuit 9 and an integral time width is set so as to be equal to a natural vibration period or the time width. When the object 2 is placed on the platform of the weighing unit 1 and a first time measurement is commenced, the weight is detected via the integrator 4 and the divider 5. The time width or the integer times the time width of the natural vibration period is calculated in the arithmetic unit 8 on the basis of a prescribed expression and a resulted value becomes an integral time in stead of a preceding calculated value, a second time measurement being commenced. Thereafter, the same operation as above is repeated. Thus, an integral time width quickly approaches the time width of one period of integral times the time width of the vibration of the weighing unit 1, rapidly increasing a measuring accuracy.
