Abstract: In the wafer position teaching method for a wafer carrying system, a teaching tool is mounted at a position of the container or the processing equipment where the semiconductor wafer is to be set. The teaching tool is sensed by a sensor provided at a wafer gripping portion of the robot. Prior to sensing the teaching tool by the sensor, external teaching tools mounted on a front external wall of the processing equipment are sensed by the sensor to roughly estimate the position of the teaching tool. Based on the estimated position, the sensor approaches and senses the teaching tool to obtain the position of the semiconductor wafer. Thus, the wafer position can be taught precisely and automatically without causing interference, even when the frontage of processing equipment is narrow.

Abstract: This apparatus relates to a materials handling apparatus that has a plurality of open-sided buckets arranged to travel along a first path having a first sense. The buckets are loadable when traveling along a first portion of the first path. An endless belt is arranged to travel along a second path having the same sense as the first path. The first and second paths coincide in a first zone so that the belt achieves closure of the buckets along a second portion of the first path. The materials handling apparatus may be operated over a wide range of conditions by the ability to preselect and change the vertical distance, and the angle of attack between a catenary string of open-sided buckets and the material to be unloaded. The method of handling material according to the present invention is readily adaptable to the unloading of railroad gondola cars, hopper barges, lighters, trucks, yard materials and the like.

Abstract: Indices in the form of colored poles are installed on a ground surface to be digged, and the indices are picked up by a television camera set on one side of a digging machine so as to set a target digging line on rectangular coordinates. Marks are applied to suitable points of the machine and are also picked up by the television camera so as to detect the positions of the marks on the rectangular coordinates. The position of the cutting edge of the machine is calculated by taking the positions of the marks as references. The result of the calculation is stored in a memory device and its content is used to display the locus of the movement of the cutting edge on the screen of a monitor television installed in the cabin of the digging machine while at the same time the target digging line is also displayed on the screen.
