Title: Method and device for focusing a microscope on structureless and reflecting surfaces, in particular of highly reflecting silicon wafers
Inventor: MATTELIN ANTOON DIPL ING
IPC: G02B21/24
Filed: 1981-06-30
Abstract: In the quality control of pure silicon wafers, the highly reflecting silicon wafers are guided through under a microscope, to which a television camera is attached, by means of positioning motors, in order to be able to determine surface defects. The high demands on the resolution of the surface defects (up to 1  mu m) require automatic focusing in the case of every microscope photograph. Because of the total reflection, this is not possible using conventional microscopes. This problem is solved according to the invention due to the fact that a diaphragm (24) is arranged in the optical axis (20) of the microscope (1) in such a way that an edge part of this diaphragm (24) is always in the workfield of the microscope (1) and that this edge part is sharply imaged in the object plane for focusing the microscope (1). <IMAGE>

Patent DE-3140924-A1 (DE)
Title: Face support assembly
Inventor: BLUMENTHAL GUENTER ING GRAD
IPC: E21D23/06
Filed: 1981-10-15
Abstract: When mining with pneumatic stowing, the pneumatic pipe line in the known face support assemblies is dismantled via window-like openings in the stowing walls of folding design. But the folding facility of the stowing wall prevents use in thin seams, because the miners can then no longer reach the coupling points via the openings. To protect the face cavity, other measures in the form, for example, of independently movable pneumatic walls then have to be taken. One wall section (10, 11) each is now allocated by the invention to the flap (5) and the curve (4) of the support assembly, which wall sections (10, 11) are vertically movable towards one another. In addition, each wall section (10, 11) is telescopic in the longitudinal direction of the face. By moving the telescopic parts (14, 15), assembly masses (36) can be created in this way, via which the coupling points (37) of the pneumatic pipe line (32) become accessible without difficulty. <IMAGE>
