Granted: 1989-11-30
Abstract: This invention is related to the method and device examining wafer by microscope, esp. testing it continuously by bringing into focus only once.  The method includes steps of ;(1) attaching wafer to wafer chuck in vacuum ; (2) testing it with moving horizontally by bringing into focus one time ; (3) giving a horizontal test continuously without adjusting focus, after 900 rotation of wafer chuck.  Because the wafer chuck has a rotary vacuum chuck in the lower part, it can absorb wafer by vacuum through a vacuum pipe.

Granted: 1999-01-15
Abstract: A prop comprises a central screw (3) and a nut composed of two parts (6a, 6b) disposed in a head (5) turning on the end of the support tube (1). Said two nut parts (6a, 6b) are movable between a position of cooperation with the screw (3) and a position in which it is separated from the screw (3), under the control of arms (12a, 12b). A return spring (16) urges said nut parts (6a, 6b) towards their position of engagement with the screw. The flanks of the thread of the nut parts (6a, 6b) are symmetrical, while the external thread of the screw (3) has asymmetrical flanks, the bottom flank having a slighter slope, thus making it possible for the screw (3) to be pulled by hand into the top position without the nut parts (6a, 6b) preventing this. Safety hooks (9a, 9b) limit the axial movement of the head (5) relative to the tube (1). The large displacements of the screw (3) in both directions can be achieved without the nut having to be turned. Fine adjustment is made with minimum rotation of the head (5). Two safety devices prevent the head (5) from moving out of the tube (1) in the case of one (8, 9) of these devices, and, in the case of the other (16), prevent the screw (3) from moving out of the head (5) and the tube (1), when the prop is inclined with its head downwards.

Granted: 1999-01-15
Abstract: A process for chemically resolving a mixture of enantiomers of primary amines, such as enantiomers of 1,3-dimethyl-5-methoxyoxindolylethylamine, provides one of the enantiomers in the form of a tartaric acid salt. In carrying out the process, an enantiomeric mixture is contacted with a chiral acid in an amount sufficient to preferentially precipitate a salt of the chiral acid and one of the enantiomers. The resulting precipitate can then be recovered. The chiral acid is selected from the group consisting of dibenzoyl-D-tartaric acid, dibenzoyl-L-tartaric acid, ditoluoyl-D-tartaric acid, and ditoluoyl-L-tartaric acid. The precipitates can be used in the synthesis of stereospecific forms of physostigmine.
