Abstract: Appareil de masquage destiné à être utilisé dans la production de dispositifs à semiconducteurs. Afin d'obtenir un alignement entre des opérations de masquage successives, des cibles d'alignement (35, 40) sont formées sur une tranche de semiconducteur (11) à proximité des motifs de circuits (36, 41) qui sont exposés sur la tranche. Les cibles d'alignement sont observées pendant les étapes de masquage successives afin d'aligner les motifs du circuit exposés au préalable avec un nouveau motif contenu sur un réticule (12, 13). Dans plusieurs étapes de masquage, la cible d'alignement est recouverte d'un ou plusieurs films très réfléchissants (49), ce qui réduit la possibilité d'observer la cible d'alignement. Un microscope à contraste de phase est utilisé pour permettre l'observation des cibles d'alignement noyées malgré l'existence des films réfléchissants superposés. Le microscope incorpore un sous-système d'éclairage (42) contenant un diaphragme annulaire (88) et un sous-système d'observation (45, 46, 49) contenant une plaque de phase (68). L'image de la cible d'alignement qui est formée par microscope à contraste de phase comprend un halo à bord lumineux (100) qui peut être utilisé pour déterminer la position de la cible.

Abstract: A novel process for preparing alpha-aspartic acid amides, particularly those suitable as non-nutritive sweeteners. This process involves the coupling reaction of an alpha-aspartate ester and a beta-hydroxy primary amine. The ester is reacted with the amine, one of which is preferably in stoichiometric excess, in a liquid phase system to form the alpha-aspartic acid amide. The amide is then recovered from the liquid phase system.

Abstract: The secondary reformer of an ammonia production process is fed with moderately oxygen-enriched air such as from a simple air separation plant producing also nitrogen, which preferably is used to aid start-up or shut-down or to keep the process plant in a hot standby condition. In such or similar processes energy economy is improved by allowing 5 - 15% of the starting hydrocarbon to pass through unreformed. 
     Hydrocarbon feedstock and steam are preheated in furnace 18, partly reacted in adiabatic catalyst 22, reheated in furnace 24 and reacted in secondary reformer 30 with oxygen-enriched air from air separation plant 27. The secondary reforming reaction is incomplete (outlet CH 4  0.7% v/v, dry basis); its outlet gas is subjected to carbon monoxide shift 35,37, steam and CO 2  removal 48, methanation 54 and drying 56, 62, and passed to ammonia synthesis (items 64-78), from which a purge stream is taken at 78 and separated at 80 to give inter alia recycle hydrogen stream 82 and methane-containing stream 86.

Abstract: A method is provided for compacting viscous polymeric moulding compositions preparatory to compression moulding to substantially improve the physical properties of articles moulded therefrom. Suitable compositions include those filled with a geometric reinforcing particulate filler that are flowable and thermosettable when compression moulded. The method comprises forming a slab of a said filler composition and thereafter reducing its thickness by passing it between spaced-apart pairs of compression means. The pair members of the compression means are spaced apart to ultimately substantially reduce the thickness of the slab passed therebetween. The method yields unexpected improvements in the tensile strength, isotropy and surface characteristics of articles compression moulded from the compounds.

Abstract: This invention relates to a movel core ring gated injection molding system. Pressurized melt from a molding machine flows through the system and into a cavity. A gate (32) leading to the cavity (34) and a bore (14) in the movable mold platen (36) are in alignment and of the same size to receive the head portion of the valve pin (16) which extends from a reduced neck portion (92). Actuating mechanism drives the valve pin between a retracted closed position to an open position in which the reduced neck portion (92) extends into the cavity (34). In the closed position, the head portion (90) of the valve pin extends a considerable distance into the bore (84) in the mold platen (78) to provide sufficient cooling to rapidly cool the melt in the cavity adjacent the pin. In one embodiment, the valve pin has a hollow portion adjacent the neck portion to provide the valve pin with thermal separation between the hot melt and the cool mold platen. In another embodiment, the valve pin has a copper portion between the hollow portion and the tip end to promote cooling of the melt in the cavity.
