Inventor: BAUBLYS SAULIUS
IPC: G05B19/40
Filed: 1986-03-21
Abstract: In a method or an apparatus (10) for the programmed inscription of cylindrical areas on workpieces (11), a tool holder (18) provided with a workhead (14) can be moved independently in a program-controlled manner by stepping motors (22, 27, 29) in the three coordinate axes (X, Y, Z) perpendicular to one another, and the workpiece (11) performs a rotation about its axis by means of a rolling device (16) during the inscription. So that there is no limit either with regard to the diameter of the workpieces (11) or with regard to the shape of the workpieces (11), provided they only have cylindrical areas, and so that in addition inscription can be carried out with work heads (14) of any type, the workpiece (11) is placed on the rolling device (16), which is independent of the tool holder (18) and can be driven independently of the workpiece (11), and the workhead (14) is moved in a programmed manner across the transverse centre (68) of the rolling device (16) or the axis of the workpiece (11). After that, a stepping motor (62, 63) of the rolling device (16) for the programmed rotation of the workpiece (11) is connected to the activating means which can also be connected to the stepping motor (29) for the movement of the workhead (14) in the horizontal-plane axis perpendicular to the workpiece axis. <IMAGE>

Title: Arrangement for testing RAMs
Inventor: WAGNER HANS-HOLGER DR ING
IPC: G11C29/00
Filed: 1986-06-06
Abstract: The invention concerns an arrangement for testing RAMs for correct working. The purpose of the invention is an arrangement for testing RAMs, on the principle of the double RAM with software comparison, which takes over the storing of the data in a way which is appropriate for the test, and thus relieves the program sequence of additional commands for this task. According to the invention, two RAMs are arranged in the arrangement, so that on writing to the first RAM the data is simultaneously inverted and written to the second memory at the inverted address. On reading, both RAMs must be addressed separately, and the inverted address of the second RAM must be taken into account by the central processing unit.
