Title: Pulse doppler type ultrasonic flowmeter
Inventor: ANZAI YOSHIRO
IPC: G01F1/66
Filed: 1997-04-08
Abstract: PROBLEM TO BE SOLVED: To enhance accuracy in the measurement of flow rate by neglecting a current A in the vicinity of the pipe wall on the receiver side where the measurement accuracy is low and determining a current distribution data C in the vicinity of the pipe wall from a current distribution data B detected with high accuracy from a part other than the vicinity of the pipe wall and then calculating the flow rate from the current distribution data B and C. SOLUTION: In the region Xm remote from the pipe wall, effect of noise reflected on a boundary face is suppressed and a normal current distribution B is detected. A current distribution indicator/corrector sets a normally detected current distribution B positive and extrapolates the positive current distribution B on the region Xm side thus determining a current distribution C by numeric analysis. The current distribution is approximated by a quadratic or cubic curve by a method of least squares, for example, and the current in the region Xm is extrapolated using that curve to obtain a current distribution as shown by a dashed line C. A flow rate calculator calculates the flow rate from the corrected current distributions b and C according to a specified formula.

Abstract: PURPOSE:To provide a multiplication device which is capable of shortening the execution time of a multiplication. CONSTITUTION:A multiplication device determining the product of a multiplier of 32 figures and a multiplicand of 32 figures is provided with a multiplying circuit 220 determining a first intermediate product from the lower rank 16 figures of the multiplier and the multiplicand and a conversion circuit 206 converting the first intermediate product into a binary expression. An invalid figure setting circuit 201 calculates the exclusive OR of values of two figures adjacent with each other in the number of 33 figures in which a code figure is added to the high rank of the multiplier. At this stage, if the high rank 16 figures of the multiplier are all invalid figures, all he arithmetic results of the exclusive OR of the values of the two figures adjacent with each other of the high rank 17 figures in the number of 33 figures become zero. Thus, a code extension is performed for the first intermediate product converted into the binary expression and the product is outputted a product without executing the conversion into the binary expression of the second intermediate product corresponding to the high rank 16 figures of the multiplier by detecting that all the high rank 16 figures of the multiplier are invalid figures and outputting a signal by a high rank invalid figure detection circuit 202.
