Title: Strain detecting method for metallic material
Inventor: SATO YASUSHI
IPC: G01B7/16
Filed: 1986-12-08
Abstract: PURPOSE:To easily detect the generation of excessive strain even at a local part such as a piping weld zone at high temperature by utilizing the principle of a four- terminal potential difference method, and measuring and comparing potential differences at every two positions determined across the weld zone. CONSTITUTION:Couples of potential difference detection conductors 15 are connected to respective points across the weld zone 4 by resistance welding, etc., and a couple of feeder conductors 16 are connected to two points outside them. The conductors 15 are connected to a fine voltmeter 13 and a recorder 11 through a scanner 9 and potential differences DELTAV between the couples of points of the resistance welding are recorded. A constant current power source 14 is connected to the conductors 16 to supply a constant-value current to between the couple of conductors 16. In this case, only one powder source 14 is used and the plural conductors 16 are connected in series. Assuming that the potential difference between the conductors before operation is DELTAV0, the potential difference ratios DELTAV/DELTAV0 from the plural couples of conductors 15 are equal as to a large-sized member like a boiler tube. When tensile stress (compressive stress to the opposite side) operates on this piping, the potential difference ratio based upon the potential difference ratio when no bending stress operates increases (decreases). The position, etc., of the stress can be detected from the variation.

Title: Speed control method for robot control device
Inventor: YAMAMOTO MINORI
IPC: B25J9/10
Filed: 1997-10-06
Abstract: PROBLEM TO BE SOLVED: To obtain a control method by which the travel speed of an optional control point of a robot does not operate at levels over a predetermined speed. SOLUTION: Input information of a key input part 31 is inputted from an output part 32 into a locus generating part 22 through a manual operation information ΔP, and the corresponding speed ΔV stored in a parameter storage memory part 21 is selected from ΔP. Then, based on ΔV, the amount of movement per unit time T is determined by ΔL=ΔV×T, based on ΔL, the generation of locus is determined by an operational target position P2 = present position P1+ΔL. Then, P2 is outputted to a speed control part 23 as an operational command, and speed monitoring control is performed based on P2. That is, V=|P2-P1|/T is calculated from P1 and P2, and from a reference speed V base stored in the parameter storage memory part 21 in relation to V, V ratio = V base/V is determined.  When V ratio > 1, the speed can be increased, when V ratio < 1, the present speed is decreased, and from the ratio of the V ratio, the operational command part 24 again prepares an operational target position P2 by P2=P1+ΔL×V ratio and P2 is outputted to a drive control part 25 as the operational command. Then these procedures are repeated for every calculation period of a control device 2.
