Patent EP-0416125-A1 (EP)
Inventor: ASABA EIKI FANUC MANSION HARIM
IPC: F16D3/04
Filed: 1990-03-19
Abstract: In general, in a metallic Oldham coupling, the transmission of a rotational force between a pair of rotary shafts cannot be carried out accurately due to the existence of a clearance. According to the present invention, an Oldham coupling body (18) is molded of a resin, and the end portions (12A, 12B) of rotary shafts (10A, 10B), i.e. members to be coupled are respectively engaged with recesses (30,32). Since the widths (LY, LX) of these recesses vary greatly with temperature, the variations of the widths are restricted by a metallic size restriction member (16). In order to prevent respective clearances from occuring in the longitudinal direction (Z) of the rotary shafts and in the direction of the depth of the recesses (30, 32) between the end portions (12A, 12B) of the rotary shafts and the recesses, a pressing force is applied constantly in the longitudinal direction (Z) by spring members (14A, 14B) provided there between.

Abstract: For high-temperature application, a multilayer wall structure is suitable which contains at least on one side a thin corrosion-resistant surface layer made of a material which forms dense oxide films on a core layer having a content of stable carbide formers which is such that their carbon activity at manufacturing and operating temperature is at most equal to that of the surface layer. This prevents a redistribution of carbon from the core layer in the surface layer and consequently improves the strength characteristics of the wall structure. Suitable carbide formers are, in particular V, Nb, Ta, Hf, Zr, Ti individually or mixed and they are provided in a stoichiometric amount for the formation of carbide, based on the carbon content of the core layer. Good results were obtained with an iron- or nickel-based core layer containing 2-5 % Nb and a chromium-containing surface layer. <IMAGE>

Abstract: The transportable, approximately cuboid-shaped storage bin and/or tool-box for small components, in particular for tools, comprises a base (1), a rear wall (2) optionally provided with suspension means, two side walls (3), a top wall (4), a front-wall folding part (5) which is connected to a top-wall folding part (6), forming the front region of the top wall, and lateral end parts (7) which complete the side walls (3). It is mounted so as to be pivotable from a closed position, 180 DEG  about a pivot axis parallel to the rear wall, to the open position and vice versa. Above the top-wall base part is provided a carrying handle (8) which extends in the container longitudinal direction and can be gripped regardless of whether the top-wall folding part/front-wall folding part unit (5, 6) is in the open or closed position. Simpler manufacture of different-sized containers and more comfortable carrying result if a linkage (9), permitting the pivoting through 180 DEG , is arranged in each case between the lateral end parts (7) of the top-wall folding part/front-wall folding part unit (5, 6) and the associated side wall (3). This linkage comprises a fixing point (10) for, respectively, one of the two ends of the carrying handle (8) extending over the entire container length. With the aid of this linkage, the top-wall folding part/front-wall folding part unit (5, 6) can be pivoted about the carrying handle (8) from the closed to the open position and vice versa. <IMAGE>

Abstract: An oral dosage form comprising
     (a) granulocyte colony-stimulating factor or erythropoietin,   (b) surfactant(s),   (c) fatty acid(s), and   (d) enteric material.   
     With the oral drug preparations provided by the present invention, therefore, inactivation of the principal ingredient during the process of pharmaceutical manufacturing has been shown to be avoided along with proven effects such as enhanced absorption of the principal ingredient from the intestinal tract particularly as a result of the addition of fatty acid to the drug composition. 
     These may be said not only to lead to a dosage reduction but also to facilitate accurate dose control and increase the practical usefulness of the bioactive proteins in the form of oral preparations.

Abstract: A reactor chamber self-cleaning process is disclosed which uses a fluorocarbon-containing gas and, preferably, C 2 F 6  in combination with oxygen. The two-step process involves, first, a chamber-wide etch at relatively low pressure and with relatively large separation between the gas inlet manifold and the wafer supports which are the RF electrodes and, second, a local etch step which uses a relatively high chamber pressure and smaller electrode spacing, to complete the cleaning of the RF electrodes.

Abstract: Ces joints articulés sont particulièrement utiles pour transmettre un courant (électrique, optique, liquide ou gazeux) qui traverse entièrement le joint articulé ou s'écoule d'un côté du joint jusqu'à des dispositifs montés sur le joint lui-même qui utilisent un tel courant. Ces dispositifs peuvent par exemple être des moteurs (240a, 240b) d'entraînement du joint lui-même. Les crochets (211a, 211b) sont typiquement mais pas nécessairement des bagues circulaires montées sur une structure interne commune qui permet à chaque crochet de tourner autour de son propre axe. Les joints articulés ainsi obtenus peuvent être mis en rotation dans toutes les directions avec une plage angulaire très large - limitée dans la plupart des cas uniquement par l'angle formé par des tiges de raccordement utilisées pour monter le joint sur une base ou pour monter des objets sur le joint afin de les déplacer. Certains joints de ce type ont des enceintes centrales creuses (264) de passage de fils métalliques ou de tubulures flexibles (261a, 261b) de transport du courant, de sorte que le courant puisse traverser oupénétrer dans le joint articulé avec le même degré de liberté, sans bagues glissantes, balais ou d'autres composants coûteux détériorables par l'usure permettant des mouvements. La structure interne commune est extrêmement simple, économique et facile à fabriquer et comprend deux pistes mutuellement adaptées (211ab), qui peuvent prendre la forme de quatre disques identiques mutuellement adaptés (211a, 211a', 211b, 211b') ou de deux paires identiques de coins à segments circulaires ayant chacun des centres décalés; ou n'importe quelle forme parmi une grande diversité de formes arbitraires qui fournissent les surfaces de guidage nécessaires pour assurer un mouvement courbe des corps.
