Patent DE-3719983-A1 (DE)
Inventor: REINDL WERNER
IPC: G06K1/12
Filed: 1987-06-15
Abstract: In known processes for labelling semiconductor surfaces by laser bombardment, either a bar code in so-called Hardmark labelling or characters in so-called Softmark labelling are applied. The new process permits labelling exempt from crystal defects by means of a bar code (Sk) in so-called Softmark labelling with a higher character density which facilitates reading and decoding. The bar coding (Sk) is produced by means of bar elements (Se) of identical width (b), each of which comprises a series of overlapping Softmark melt points (SSp) obtained by laser bombardment. For preference, narrow bars (sSt) are composed of one bar element (Se) and broad bars (bSt) of two bar elements (Se) positioned a small distance (a) apart. The new process permits labelling exempt from crystal defects of semiconductor discs, in particular silicon wafers.

Title: Dowel with expansion sleeve
Inventor: FISCHER ARTUR PROF DR
IPC: F16B13/06
Filed: 1987-08-17
Abstract: In the case of the dowels provided for use in the tension zone of an anchor base, the widening of the bore as a result of crack formation can cause axial displacement of the expansion sleeve, which results in considerable slippage, in some cases even in failure of the anchorage. In order to permit or to improve the follow-up expansion of the dowel, the invention provides, as a bearing element, a spring lock washer (11) which has an external diameter greater than the diameter of the expansion sleeve and which can be compressed to the diameter of the expansion sleeve. In order that secure bracing of tbe spring lock washer (11) in the bore (8) is achieved, an expansion surface (20) engaging into the spring lock washer (11) may be provided on the expansion sleeve (1). <IMAGE>
Patent DE-3728296-A1 (DE)
Title: Work-carrier stand
Inventor: WITZMANN LASZLO
IPC: B65D19/44
Filed: 1987-08-25
Abstract: The work-carrier stand consists of stacking frames (1.2) which can be put onto a base frame (1.1) and in which transport cassettes (4) can be inserted in each case. The transport cassettes (4) can be subdivided at variable distances apart transversely to their longitudinal axis by dividing-wall elements (5.1 or 5.2) so that, for example, round workpieces (W), when put on, are automatically orientated parallel to the longitudinal axis and are held at the same distance (A) apart. Thus, exactly reproducible robot access becomes possible, because axial distance identity or 0-point orientation to marginal stops is achieved by a dividing wall (5.2) with a leaf spring (6) braced on the workpiece side being provided in front of one end face of each of the workpieces (W). Here, the top margin (10) of the dividing wall (5.2) comes to lie only just above the centre of a conventional workpiece (W) so that unimpeded gripper access from above with exact preset positioning via NC programs or the like is ensured. Furthermore, reliable selection of each workpiece position is guaranteed by diverse centring measures (2.3, 3.5, 4.4) on columns (2.1, 2.2), frames (3.1 and 3.2) and supporting V-blocks (4.2) or supporting bases (4.5). <IMAGE>
