IPC: G01L5/04
Filed: 1997-04-30
Abstract: PROBLEM TO BE SOLVED: To establich a measuring method for a tension distribution which does not damage a sheet material and does not generate an interference, by a method wherein an elastic body which is softer than an elastic metal is buried into the inside of a tube made of the elastic metal so as to form a roll, the sheet material is pressed to the surface of the roll and the tension distribution of the sheet material is measured on the basis of a displacement distribution on the surface of the roll. SOLUTION: A roll 2 is composed of a tube 3 whose outer surface is made of a thin metal, its axial center is provided with a central shaft 4 made of a metal, and the inside of the tube 3 is buried with an elastic body 5 whose Young's modulus is low. The elastic body 5 is a metal or a nonmetal such as a plastic or the like so as to be made softer than an elastic metal for the tube 3. The roll 2 is turned freely, a sheet material 1 is stretched in such a way that the roll 2 is wrapped. The material 1 is pressed to the surface of the roll 2 by the tension of the material 1. The displacement on the outer surface due to the deformation of the roll 2 is detected. As displacement detection means, a plurality of detecting elements 61 , 62 ,... are installed at a displacement sensor 6 which detects a displacement amount in every discrete detecting point.  As a result, the surface of the roll 2 becomes an integral tube, and the roll damage and the interference of the sheet material 1 are eliminated.

Abstract: PURPOSE:To prevent time for processing from being prolonged even when the number of recognizing object characters is increased by calculating a distance between rough classifications at high speed by providing a feature amount distribution storing means and a distance table preparing means. CONSTITUTION:A feature amount distribution storing means 8 is provided to store the maximum and minimum values of a feature amount for each dimension of the feature amount for rough classifying a recognition dictionary, and a distance table preparing means 9 is provided to prepare a distance table for each dimension by calculating a distance between the feature amount within the range of the minimum and maximum values for the feature amounts of the respective dimensions stored in the means 8 and the feature amount of the relevant dimension in the input pattern. In a rough classifying means 5a, the value of a distance between each character of the recognition dictionary and the input pattern is calculated by using the distance table prepared by the distance table preparing means. Thus, the distance is calculated only concerning the feature amount within the range of distributing the feature amounts of the respective dimensions, and the calculation of the distance to the character having the same feature amount in the same dimension of the recognition dictionary is omitted. Therefore, the time for calculating the distance between the rough classifications can be shortened.
