Abstract: A magnetic chuck has a housing (1), a top plate (2) fixed to the housing, and an inner system (3) provided within the housing under the top plate. The top plate (2) comprises a plurality of spaced pole parts (7) of soft-magnetizable material and parts (9) of substantially non-magnetizable material positioned between them. The inner system (3) comprises, in a similar division as with the top plate, a plurality of pole parts (6) of soft-magnetizable material and magnetic elements (5) positioned between them. In the inner system (3), the center distance of adjacent pole parts (6) and magnetic elements (5), respectively, the so-called pole pitch, is smaller than ca. 8 mm. The inner system (3) is slidable parallel to the top plate (2) between the on- and off- positions, by means of a spindle and nut drive (11) and it can assume all intermediate positions. The magnetic chuck can particularly be used in combination with a pallet for reproducible positioning on the working table of a machining apparatus, wherein the pallet (4) is constructed as housing for the magnetic chuck. If the magnetic chuck is used in a condition submerged into a fluid, a fluid supply line is connectable to the chuck, and flushing holes (21) for the fluid open through the upper surface of the top plate. Said flushing holes (21) are distributed in a regular pattern (23) on the surface of the top plate (2) and are provided with screw-thread for receiving tap bolts of mechanical clamping elements or the like.

Abstract: Selon un procédé de fabrication d'un dispositif à semi-conducteur tel qu'un dispositif MOS, on forme une coiffe (204) en nitrure sur une interconnexion (104) éloignée de matière de porte. Dans une étape ultérieure de croissance d'oxyde, on forme de l'oxyde (140) sur une autre interconnexion (106) éloignée et des portes de transistors, tandis que la coiffe en nitrure empêche la croissance d'oxyde sur la première interconnexion éloignée. On élimine l'oxyde mince se trouvant sur les régions de source et de drain, laissant des formations d'oxyde sur les portes et la seconde interconnexion; on retire également la coiffe en nitrure. Ensuite, on forme de la siliciure (134, 135, 138) sur les régions de source et de drain et sur des parties de la première interconnexion éloignée. On dépose une couche (132) conductrice et à partir de celle-ci on configure une interconnexion locale, laquelle connecte électriquement la première interconnexion éloignée à au moins une région de source/drain sans utiliser d'interconnexions entre couches. Cette interconnexion locale passe sur la seconde interconnexion éloignée, tout en étant isolée de cette dernière par la formation d'oxyde. Le résultat de ce procédé est un dispositif à circuits intégrés présentant cette interconnexion en pont ainsi que des dimensions compactes, ces dernières étant dues aux tolérances larges que permettent les caractéristiques d'auto-alignement du procédé.

Abstract: A mixer for liquids and liquid suspensions has a motor drive and housing which is portable and can be carried from tank to tank and attached to the tank where mixing is carried out. The housing depends from the yoke and contains a quill (48) which is driven by the motor drive. A latch (84) is pivotly mounted on the outside of the quill and has a tab (92) which extends into the quill. The tab latches on to a rim of the mixer shaft when the shaft is inserted into the quill. The latch is held by a spring (97) suitably provided by a expansible lock ring so as to enable the latch to pivot as a lever about a fulcrum. The shaft is locked in the quill by a manually actuable connector (120) (suitably a set screw) which is disposed in alignment with the latch in order to align the quill with an opening for a tool which is manually actuable to lock the shaft in place with the set screw. An indicator surface (96) is provided on the latch facing an indicator (100) which is mounted in the housing. The indicator is preferably flexurally mounted in an opening in the housing so as to enable it to be used as a button to pivot the latch in order to release the mixer shaft.

Abstract: Disclosed is a process for manufacturing a wear and corrosion resistant iron-alloy, powered metal or sintered carbide component. In a first step, the component is subjected to an initial thermochemical treatment preferably consisting of nitriding, in a closed furnace in order to form onto the surface of the component a nitrogen diffusion zone followed by the superficial layer consisting of γ' and ε nitride layers. In a second step, an aqueous solution comprising oxygen, carbon, nitrogen and, optionally, sulfur is introduced into the furnace for a period of time sufficient to allow transformation of the ε nitride layer into a porous layer of ferrous oxide(s). This process is particularly efficient and permits to produce a superficial porous ferrous oxide layer thicker than 2 µm onto a nitride steel component.
