Abstract: A method of providing in a self-registering manner underpasses in a semiconductor device having insulated gate field effect transistors, in which the underpasses below the field oxide connect together electrode zones of the field effect transistors. The field oxide (9) is obtained by local oxidation by means of an oxidation mask (10,11). After a first oxidation treatment a part of the oxidation mask (10,11) is removed and the semiconductor body (1) is doped locally with As or Sb atoms for the underpasses (8). The aperture in the doping mask coincides substantially with the part of the oxidation mask (10,11) to be removed, without critical alignment being necessary therefor, in that the masking effect of the already obtained oxide (27) is used. After the doping treatment a second oxidation treatment is carried out to complete the field oxide (9).

Abstract: An automatic cold start fuel supply device for use with constant depression carburetters having a damped air valve, comprises a fuel metering needle movable with engine temperature by a bimetallic element which acts on it indirectly via a rotary member. A spring, which is normally compressed by the action of manifold depression on a diaphragm, is adapted to act when expanded, through the diaphragm and a lever on an arm of the rotary member. The geometry of the lever and the rotary member is such that the rotary member is so positioned by the bimetallic element when the engine is warm that it is not rotated by the load that is applied to its arm by the action of the spring whereas it is so rotated against the action of the bimetallic element when the engine temperature is below the normal running temperature.

Abstract: A method for treating an olefin polymer, which comprises contacting an olefin polymer obtained by polymerizing an olefin in the presence of a catalyst composed of (A) a highly active transition metal compound, (B) an organoaluminum compound and (C) a carbonyl- or Si-containing electron donor, with (D) an organometallic compound of a metal of Groups I to III of the periodic table after the polymerization. This method can markedly reduce the amount of an electron donor remaining in an olefin polymer after polymerization, the electron donor being an ingredient of a catalyst used in the polymerization and constituting the main cause of an offensive odor which the resulting polymer gives off.

Abstract: The lower end of a tubular bundle 14 min  of fibres is impregnated with a potting compound by a centrifugal technique in which the bundle 14 has its bottom end supported in a mould 12 which is rotated by a motor 22 through a belt drive 26, 28, 16. While the mould 12 and the bundle 14 are being rotated, potting compound is supplied from a reservoir 36 through a hose 38 and a duct 40 to the bottom of the bore of the bundle 14 within the mould 12. Centrifugal force causes the potting compound to flow outwards through the bundle until it fills the mould 12. The centrifugal force displaces air bubbles held between the fibres and ensures complete encapsulation of the fibres. When the mould 12 is full, spinning and the supply of potting compound is stopped and the end of the bundle 14 is left in the mould 12 until the potting compound has reached a desired state of cure.

Ces elements ou des elements analogues peuvent etre utilises avantageusement pour d'autres angles de faitage egalement, puisqu'une inclinaison relative des elements de toiture produit des ecartements reduits seulement entre la surface de ces elements et les parties non engagees des bords de tuiles (10), et qu'un scellement complet ne requiert que des quantites relativement faibles de composes de scellement. Dans la pratique, on pourra donc utiliser un seul type de tuiles de faitage pour tous les angles de faitage y rapportant. De preference les bords de tuiles sont pourvus de bandes compressibles de scellement permettant normalement d'eviter toute utilisation supplementaire d'un compose de scellement, ce qui facilite grandement le montage des tuiles.

Abstract: An integrated circuit (lC) has an oscillation circuit (OSC), for generating clock signals (CLOCK), an internal logic circuitry. When the internal logic circuitry (IC) is not required to be in a operational mode, operations thereof and operations of the oscillation circuit (OCS) are terminated. To prevent misoperations the internal logic circuitry is restored to the operational mode only after restored operations of the oscillation circuit (OSC) are stabilised. 
     A misoperation prevention circuit comprises an integrating circuit (R, C) which receives a control signal for restoring operations. The integrating circuit delivers a voltage which increases as time passes. A first gate circuit (G,), having a lower threshold level, is arranged to receive the voltage provided, by the integrating circuit (R, C) and when that voltage reaches the lower threshold level operations of the oscillation circuit (OSC) are triggered. A second gate circuit (G 2 ), having a higher threshold level, is also connected to receive the voltage provided by the integrating circuit (R, C). Only when the voltage provided by the integrating circuit reaches the higher threshold level, after a time sufficient for stabilization of the oscillation circuit (OSC) does the second gate circuit (G 2 ) provide a control signal (A) which restores the internal logic circuitry to the operational mode.

Abstract: in a method for forming a patterned resist layer on a semiconductor body (6), a layer of negative-working resist on the semiconductor body is heated in an atmosphere (4) which is free from any oxidizing gases, after an energy radiation has been projected onto desired regions of said resist layer, so that post-polymerization of said negative-working resist is substantially accomplished and then the exposed and post-polymerized negative-working resist is developed. This can provide a high dimensional accuracy of the resulting resist patterns and constant thickness of the resist coating in the exposed area after developing. It can also provide an increased percentage of the thickness of the residual resist coating to the initial coating thickness. Further, it can enable straight-line processing of the resists.
