Title: Teaching playback robot for arc welding
Inventor: KODAIRA AKIO
IPC: G05B19/404
Filed: 1982-01-12
Abstract: PURPOSE:To execute welding exactly, by calculating an absolute coordinate of a teaching point by a weld line detecting sensor, and correcting teaching data. CONSTITUTION:To 2 points each per 1 segment path, teaching is executed in accordance with welding order (in order of P1, P2, C1, P3, P4, C2...P7, P8, C4, P1). After teaching has ended, in case when there is a difference between the actual welding path and the teaching welding path due to an installation error and a dimension error of an object to be welded, the teaching welding path is corrected. That is to say, prior to welding, a welding torch 14 is positioned at each teaching point Pi (i=1, 2...8) to the object to be welded, and at this position, 1 point on a weld line being in the vicinity of the torch 14 is detected by a  weld line detecting sensor 16, and an absolute coordinate value of this point is  operated and derived by a controlling device 18, and it is denoted as Pi'. At the same time, each bent point Cj' (j'=1-4)) is calculated by the controlling device  18, as an intersection point of 2 straight lines or a middle point of a short distance straight line for connecting the 2 straight lines. Thereafter, in order of P1'- P2'- C1'-P3'-P8'-C4'-P1', the welding torch 14 is operated to perform a playback operation, and the welding work is executed.

Filed: 1985-01-14
Abstract: PURPOSE:To minutely move a moving table with respect to a base by forming a thin-walled part by means of plural holes provided on a board body and making the elastic deformation of said part function as parallel springs. CONSTITUTION:The centers of five holes 2 which are provided through a board body 1 are lined on perpendicularly intersecting axes X, Y.

Title: Pin grid array package
Inventor: UEDA NAGAMASA
IPC: H01L23/50
Filed: 1989-01-10
Abstract: PURPOSE:To improve an yield and achieve a low cost by making a first layer electrode pin penetrate into a second layer through hole. CONSTITUTION:A first layer has a lead frame on the surface, and has protruding electrode pins on the opposite surface. The lead frame and the electrode pins are electrically connected. A second layer has the same structure as the first layer, and has through holes into which the electrode pins of the first layer penetrate. By assembling them as shown in figure, a pin grid array package (PGA) provided with pin arrangement is formed. As a result, the wiring between the electrode pins and IC silicon chip electrodes can be divided into two surfaces, i.e., the first layer surface and the second layer surface. The number of leads formed on one surface can be reduced to 1/2 of the conventional PGA. Thereby, the yield of PGA is improved and the cost is reduced.

Filed: 1989-01-12
Abstract: PURPOSE:To enhance the light guiding efficiency of a light guide and to precisely detect a fault by forming a diffusion part in a shape in accordance with the aberration of a lens array and uniformly trapping scattered light having a scattering angle within a specified range out of reflected light. CONSTITUTION:The diffusion part 21 provided on the surface of the light guide 9 is decided to have such a shape that the obtained range where images in terms of all the scattering angles theta can be covered becomes a graphic which is symmetrical with reference to a point Q. A collimated scanning beam 13 is reflected on the surface of a reagent 3 and converged on the diffusion part 21 through the lens array 7, then guided to photoelectric converters 11 on both ends through the guide 9. The diffusion part 21 is formed in such a shape that diffusion can be efficiently performed according to the aberration of a convex lens constituting the array 7 and uniform sensitivity is provided over a scanning width, so that the angle range of the scattered light trapped by the guide 9 does not depend on the change of the angle theta and a spreading angle phi becomes constant. As a result, attenuation in guiding the light by means of the guide 9 is small and the light guiding efficiency is enhanced.

The output signals of an anemoscope 7, an anemometer 8 and plural strain gauges 9 for detecting the propulsive force of the sail 3 are entered into a controller 10 including a first adjustment means for driving the sail 3 to the optimal sail angle alpha as to the relative wind direction angle beta on the basis of previously stored model data, and a second adjustment means for driving the hydraulic motors 6 to finely rotate the sail 3 from the optimal sail angle alpha to a sail angle corresponding to the maximum propulsive force of the sail and determined through the detection of the propulsive force of the sail. The maximum value of the propulsive force of the sail 3 is thus determined on the basis of the model data to control the sail to the position of best angle.

Title: Defect kind classification method of surface plate defect data
Inventor: ISHIWATA OSAMU
IPC: G06T7/00
Filed: 1990-01-11
Abstract: PURPOSE:To judge the form of a continuous address group, classify the kind of defects, and enable the number for each classification, by obtaining specified values in a region, from the number of addresses of a continuous address group in a rectangular address region circumscribing the continuous address group, and the respective numbers of addresses in the longitudinal direction and the transversal direction. CONSTITUTION:From the number (m) of addresses of a continuous addresses group whose continuity is recognized, the number (a) of address in the longitudinal direction of a rectangular address region circumscribing the continuous address group, and the number (b) in the transversal direction of said address region, the length D of a diagonal line of the region can be obtained, and further a ratio number m/D can be obtained. From the ratio number a/b of the numbers (a), (b), or the numerical value of the ratio number m/D corresponding with a/b, the form of the continuous address group is judged, and the kinds of defects are separated and outputted. When the numbers (a), (b) are equal to 1 or decimals approximate to 1, the defect is judged to be an isolated foreign matter. In the case of surface type contamination, the area of the continuous address group is larger, so that the number (m) is fairly larger than (a) and (b). The ratio number m/D exceeding a judging range is judged to be surface type contamination.
