Title: Method for predicting reflectance and transmittance of noise
Inventor: UCHIUMI MASAHIKO
IPC: G01H17/00
Filed: 1998-01-13
Abstract: PROBLEM TO BE SOLVED: To shorten the calculation time while reducing the cost by determining a characteristic function representative of an wave equation at the cross-sectional area varying part of a circular pipe using spherical coordinates having an origin at the vertex of a conical side wall face thereby eliminating large matrix operation. SOLUTION: When the radius r of a circular pipe 1 is tapered linearly from a1 to a2 in a range of 0<=Z<=1, spherical coordinates having an origin O at the vertex of conical face of the circular pipe 1 is set thereon and Z coordinate is denoted by Ztop. Solution of an wave equation is then determined in the circular tube region of the pipe 1 and in the cross-sectional area varying part (conical region) using the spherical coordinates. The solutions are substituted for the continuous conditions of sound pressure and medium velocity at Z=0 and 1 and the absolute ratios of reflected and transmitted waves C2mn , C3mn to an incident wave C1mn , i.e. reflectance Rmn =|C2mn /C1mn |, transmittance Tsn =|C3mn /C1mn |, are determined. Since a high dimensional matrix operation is not required, the calculation time can be shortened while, reducing the cost.

Abstract: PURPOSE:To quickly adjust a position by discriminating the direction of the dislocation of a read sensor by comparing a picture signal at the time when a reference pattern on an original is scanned and read by the read sensor with pattern information. CONSTITUTION:The read sensor 1 scans the original by a scanning signal supplied from a scanning circuit 2, and outputs the picture signal corresponding to the density of a picture element on a scanning line.
