Title: Apparatus and method for the production of ribbed pipes.
Inventor: JARVENKYLA JYRI
IPC: B29C48/13
Filed: 1986-07-03
Abstract: This invention relates to an apparatus and a method for the production of outwardly ribbed, plastic pipes. The apparatus includes a core around which a plasticized material is pressed from a nozzle. A kernel having an essentially constant diameter is positioned at the terminal end of the core for a smooth inner face of the pipe. The outer face of the pipe is ribbed by grooves of axially displaceable chill moulds. The end zone of the kernel is provided for the cooling of the inner face of the pipe. In known apparatuses the grooves of the chill moulds are often filled incompletely and the inner face of the pipe becomes uneven on account of air bubbles, for instance. These disadvantages are avoided by heating an initial zone of the kernel for heating the inner face of the pipe and by shaping the surface of the initial zone to slightly expand conicallly in the production direction.

Abstract: Le système ci-décrit comprend une source de rayonnement électromagnétique (1) polarisé telle qu'un laser dont le rayonnement de sortie est transmis à un modulateur de polarisation (2). Ce dernier, sensible aux informations numériques provoque, à des périodes d'horloge successives, des modifications dans la polarisation du rayonnement. Le rayonnement polarisé est transmis le long d'une fibre optique (4) à un récepteur où il est couplé à une autre onde optique de polarisation fixe. Le rayonnement IF résultant est détecté par un détecteur (7) et la phase et/ou l'amplitude différentielles du rayonnement IF détecté sont déterminées. A partir de cette information, les données numériques originelles sont reconstituées.

Abstract: A circuit for operating low-pressure discharge lamps at elevated frequency comprises a reconnect circuit which disables the disconnect circuit upon exchange of a defective low-pressure discharge lamp (LP1). The disconnect circuit comprises a diode (D10), a resistor (R11) and a thyristor (TH) together with a trigger circuit (5). The reconnect circuit comprises a capacitor (C9) and a resistor (R12). Upon removal of the defective low-pressure discharge lamp (LP1), the capacitor (C9) is charged over the resistor (R12). Upon insertion of a new low-pressure discharge lamp (LP1), the capacitor (C9) is discharged and recharged in opposite direction and the holding current is removed from the thyristor (TH). This causes the thyristor (TH) to block, and enables the push-pull frequency generator (3) to start oscillating again.

Abstract: Un procédé de mesure de propriétés, notamment de la teneur en matière sèche d'une composition formée d'un liquide et de particules solides, consiste à appliquer (E, 3, 9, 45) à la composition un rayonnement électromagnétique, dont la longueur d'ondes choisie est plus petite que les particules de plus petites dimensions contenues dans la composition devant être mesurée. Les dimensions de la zone recevant le rayonnement sont maintenues sensiblement constantes et la composition et la zone recevant le rayonnement sont déplacées l'une par rapport à l'autre. Un appareil de mesure (6, 12, 9, D) est utilisé pour mesurer l'intensité du rayonnement réfléchi ou diffusé à partir de la zone recevant le rayonnement électromagnétique. Les variations d'intensité provoquées par les particules (P) voyageant à l'intérieur et à l'extérieur de la zone devant recevoir le rayonnement, sont utilisées pour identifier la configuration des particules et pour produire, sur la base de cette configuration, des signaux représentant lesdites particules. Lesdits signaux sont traités en un message proportionnel aux propriétés observées, notamment la teneur en matière séche d'une composition.

Abstract: The process is particularly useful in the fabrication of GaAs quantum well (QW) laser diodes. Starting point is a ridge-patterned (100)-substrate (21), the crystal orien­tation of the sidewalls, e.g., (411A)-oriented, being different from that of the horizontal top. The sidewall facets thus have a lower Ga incorporation rate. 
     In a molecular beam epitaxy (MBE) system, the lower AlGaAs cladding layer (22) is first grown, followed by the high-temperature growth of the active GaAs QW (23). Due to diffusion and desorption processes, the GaAs thickness at the sidewalls (23E) is smaller than on the hor­izontal top (23R) of the ridge. During a short growth inter­rupt, the GaAs completely desorps from the sidewall facets. With the subsequent growth of the upper cladding layer (24), the QW becomes laterally embedded in higher bandgap material providing for lateral electric confine­ment.
