Abstract: A workpiece identifying method is provided, being characterized in that a plurality of identification areas of plural columns and rows are plotted in an identification mark providing region provided in the area of the unused portion of a workpiece or a product, identification holes are formed in the proper number of identification areas, whereby an identification mark is provided to the workpiece or the product. A workpiece is produced with identification holes formed in the proper number of identification areas. An identifying method for detecting the identification holes formed in the proper number of identification areas of the workpiece and workpiece identification apparatus are also provided. Sheet metal machining apparatus is further provided, having the workpiece identification apparatus placed in a workpiece feed device side or a carry-away device side for a sheet metal work machine. Thus, an identification mark is easily and surely provided to the workpiece, making it easy to identify the same.

Abstract: Apparatus for processing a menu device comprising a card; bubbles on the card having positions corresponding to selectable data; each bubble having a first position projecting upwardly from the plane of the card, and a second position into which it is displaced relative to the plane of the card, by finger pressure, to indicate selection of data corresponding to bubble position on the card, the apparatus comprising first structure for detecting which of the bubbles are so displaced, and; second structure to engage displaced bubbles and to urge them back toward the first positions after the first structure detects which of the bubbles are displaced to second positions.

Abstract: In fabricating very-high-resolution devices with a lithographic tool such as an EBES machine, it is crucial that the planar mask or wafer members utilized therein be loaded into and maintained in the work chamber of the machine in a way that minimally affects their planarity. In accordance with the present invention this is accomplished by loading each member into a three-point-suspension cassette unit by means of a fixture that performs the loading in a precise and essentially stress-free manner.
