摘要:
Dimensions of a plurality of works of the same specification are subtantially identical among the works. Thus, a teach work point on the work to be worked by an industrial robot and a teach reference point to specify the teach work point are taught to memory means of the industrial robot. In an automatic mode, an actual reference point on the work of the same specification is detected by a sensor and an actual work point of the work is determined based on a difference between the detected actual reference point and the teach reference point and the resulting actual work point is conveyed to the industrial robot.

A memory system has a first memory such as a magnetic bubble memory and a second memory such as a RAM having a faster access time than the first memory. The first memory is divided into a plurality of blocks each of which has program steps stored therein. The second memory has a plurality of unit chains which correspond to the blocks of the first memory respectively and in each of which step information representative of the number of steps stored in the corresponding block and pointer information indicative of a connection to a next block are stored. The step information in the unit chains are successively read in accordance with predetermined start block information and the pointer information to count the total number of steps on the basis of the read step information. From the first memory is read information in the block corresponding to the unit chain of the second memory with respect to which the counting is made when the counted number of steps reaches or exceeds a program step number to be detected.

In accordance with levels of skillfulness of operators, guidance of a robot teaching apparatus is automatically changed for facilitated use by beginners and skilled operators. Teaching is performed through an interactive procedure with the aid of a display of message for manipulation guidance and a menu for input selection. A key manipulation path is automatically determined on the basis of various experience factors. For a skilled operator, operation up to generation of a final function display is executed in an automated manner.
摘要:
An implosion protected cathode ray tube which comprises a glass envelope having a faceplate; and a layered protective structure deposited over and positioned frontwardly of the faceplate. The layered protective structure includes a first resin-coated layer held in contact with the faceplate, a hard coated layer for protecting the first resin-coated layer and a second resin-coated layer formed between the first resin-coated layer and the hard coated layer. The first resin-coated layer has a hardness which corresponds to 1H or lower of hardness of drafting pencil lead, and an elongation at breakage within the range of 65 to 85%. The first resin-coated layer also has a break strength of 3.5 kilograms per square millimeter or greater. The hard coated layer has a hardness which corresponds to 5H or higher of hardness of drafting pencil lead, and an elongation of 3% or smaller at breakage. The second resin-coated layer has a hardness generally intermediate between the hardness of the first resin-coated layer and that of the hard coated layer and also an elongation at breakage generally intermediate between the elongation of the first resin-coated layer at breakage and that of the hard coated layer at breakage.
