Abstract: In the case of a brake cylinder, for example a combined cylinder (1) comprising a service brake cylinder (3) and a spring brake cylinder (5), a housing (31) of the spring brake cylinder connected to a partition wall (7) of the combined cylinder is provided, which is manufactured with an irregular wall thickness by the ironing process, that is to say that the base (13) of the housing (31) supporting the pre-loaded spring (11) has a greater wall thickness than the shell of the housing extending axially from the base, which is subjected to lower stresses. On the end face of the housing shell radially extending interlocking segments (33) formed by the ironing process are provided, which can either be connected to the partition wall (7) by means of direct bayonet engagement or can be interlocked with the partition wall with the aid of a separate bayonet ring (35). <IMAGE>

Filed: 1991-08-13
Abstract: A process for manufacturing an integrated circuit having both field effect and bipolar transistors provides, in one embodiment, a polycide film over the gate and field oxides on the surface of the semiconductor substrate. The process then patterns the polycide film such that a protective structure of gate material is formed on top of the base region of the bipolar transistor while the gate of the field effect transistor is formed, in a single process step. The channel region of the field effect transistor is defined by the gate, which also serves as a mask for etching away the gate oxide from the source and drain regions of the filed effect transistor. Ionic species are implanted to form the source and drain of the field effect transistor and the collector contact of the bipolar transistor. The protective structure of gate material in the active region of the bipolar transistor is removed just before the base region is implanted with ionic species to form the base of the bipolar transistor. A polysilicon or polycide film provides the emitter of the bipolar transistor.

Abstract: The invention relates to the memories in an integrated circuit, in particular the electrically programmable memories. 
<??>The memories are provided with redundancy means (MR, MR' SW1 to SW4, CMP) enabling defective columns of cells to be repaired. These means modify the addressing of the memory so that the repair is transparent to the user. Furthermore, in order to carry out a more rapid test of the memories, it is customary to perform a grouped test consisting in programming several columns at once. There is sometimes an incompatibility between the addressing modifications due to the grouped test and those due to employing redundant columns. To prevent this, the present invention provides means (CMP, ND) for addressing, in grouped test mode, not only several columns of the memory, but also the redundant columns possibly employed as a replacement for one of these defective columns.

Abstract: On décrit des procédés destinés à effectuer des évaluations en temps réel de la concentration d'un soluté cible ainsi qu'à contrôler le profil structurel de ce soluté cible dans une solution. Des techniques chromatographiques à affinité, à liaison non difusante, sont utilisées pour produire des chromatogrammes présentant des courbes de percée nettement définies. En fonction de la différence entre la concentration détectée à l'équilibre des impuretés qui passent à travers la matrice et la concentration de tous les solutés de l'échantillon, la concentration du soluté cible dans la solution peut être déterminée. Alternativement, un chromatogramme représentant le profil structurel d'une protéine dans un échantillon comprenant un mélange de variantes structurelles peut être produit d'après le procédé de l'invention. Les dosages peuvent être effectués en temps réel de sorte que la production ou la purification d'une substance précieuse telle qu'une protéine de recombinaison pharmaceutique ou une substance analogue peut être contrôlée de manière significative.
