Abstract: Un moteur à air comprimé du type à piston alternatif comporte un piston (14) connecté à une tige (13) de piston. L'arrivée de l'air comprimé sur les côtés opposés du piston est réglée par un élément de valve de commande (16) qui est couplé par un mécanisme d'actionnement à la tige de piston, pour que l'air soit fourni à tour de rôle aux côtés opposés du cylindre (10) qui contient le piston. L'air sort des extrémités opposées du cylindre par des valves de sortie respectives ayant chacune un diaphragme (32). Les valves de commande de sortie règlent le flux d'air dirigé sur les conduites d'échappement (31, 35) conçues pour que la détente de l'air s'effectue dans des parties de ces conduites éloignées des valves de commande de sortie, ce qui minimise les risques de formation de glace dans les valves de commande de sortie.

Abstract: A method for allocating and restoring a bit-stream, in which when the code amount of the bit-stream generated as a result of variable-length encoding with respect to macro blocks included in a segment exceeds an allowable segment capacity, the excess bit amount is maintained at its maximum in a range where compatibility with a conventional SD-VCR is guaranteed, to thereby improve the quality of a reproduced image, and data compressing/decompressing apparatuse suitable for the methods is provided. The method for allocating the bit-stream includes the steps of: (a) allocating the bit-stream of each DCT block, generated as a result of quantizing and variable-length encoding the DCT coefficient of each DCT block, to DCT block within the macro block; (b) reallocating the bits remaining during the step (a) to another DCT block within macro block; (c) reallocating the bits remaining during the step (b) to another macro block within the segment; (d) reallocating the bits remaining during the step (d) to another segment having the macro block of the same content as that of previous or following frame. In this method for allocating the bit-stream, when a remaining bit amount in a segment unit is generated, the remaining bit amount is propagated to an adjacent segment and is recorded therein so that deterioration of the reproduced screen can be prevented.

Abstract: An encoding and decoding apparatus quantizes LSP (Line Spectrum Pair) parameters, which are characteristics parameters of spectrum information included in a voice signal, with high accuracy and stability. This encoding and decoding apparatus comprises a first quantizing means of which quantization is performed independently in the unit of one frame, and a second quantizing means which uses a correlation between adjacent frames. An error comparing means compares quantization errors produced by the first quantizing means and quantization errors produced by the second quantizing means to select either one quantizing means whose quantization errors are less than that of the other. The first quantizing means produces a highly accurate quantization with stability regardless a condition of an input voice signal, while the second quantizing means produces a highly accurate quantization when input voice signal stays quasi-stationary. By switching these two quantizing means, this apparatus can offer stable and high accurate quantization regardless a condition of the input voice signal.

Filed: 1994-10-25
Abstract: La présente invention concerne un système (10) de distribution de phases et de fréquences d'horloge utilisant une onde sinusoïdale stationnaire. Ce système, qui comporte dans sa totalité un nombre important de recoupements sensiblement simultanés tout en consommant peu d'énergie, ne nécessite aucun système de terminaison de bus ni aucun contrôle précis des caractéristiques (Zo) du chemin de transmission. Ce système, particulièrement avantageux pour les applications haute fréquence et notamment numériques, linéaires (non ramifiées) et de fond de panier, convient également aux topologies en étoile, en anneau ou maillées. Le système se compose d'un générateur d'onde sinusoïdale stationnaire (20) comportant une partie circuit d'excitation (42), d'un bus d'horloge (25) et de récepteurs de signaux d'horloge (30a...n). Les récepteurs de signaux d'horloge présentent une forte interférence d'impédance avec le bus d'horloge (25). Les principes de base de conception et les paramètres limitant et définissant le rendement tiennent compte d'un délai maximum de propagation entre deux points quelconques du système, de la capacitance basse fréquence totale du système, et du Q du système qui doit être élevé à la fréquence de l'onde stationnaire tout en satisfaisant aux exigences de faible consommation et de synchronisme. Pour que la longueur du système ne soit pas source de problème, certaines réalisations utilisent un dispositif maître/esclaves délivrant un retour de phase aux modules esclaves. L'invention concerne également des systèmes multifréquence.

In a threaded neck ring on the container a valve is threadingly retained. The valve is a combined gas- and liquid valve with passages for gas as well as liquid. On the valve and the neck ring planar, parallel, opposite ring faces are formed between which the sealing ring. From the ring face of the valve, a cylindrical projection protrudes and extends downwards to the ring face of the neck ring. Between the valve and the neck ring there is a slot space through which an overpressure in the container can be relieved when the valve is being dismounted. The projection serves the purpose of preventing this slot space from being closed for flow of gas by some of the sealing ring which is squeezed up into the space by the gas overpressure and preventing this space from being relieved, so that an operator, when dismounting a valve is exposed to the risk of being hit by the valve, if this, by the gas overpressure, is being thrown out into the room in the very moment when the valve releases its engagement with the neck ring.

Abstract: A method for making improved optical quality lenses is described. The method includes arranging a mold having a molding surface, a curable optical quality resin composition, and a plastic lens preform of optical quality material such that the resin composition is disposed between, and in contact with, the plastic lens preform and the mold. Upon curing, the resin composition forms a cured plastic attached portion that is bonded to the plastic lens preform. The resin composition and plastic lens preform are selected such that the attached portion has a higher scratch resistance, a lower chromatic aberration, and/or a higher ease of edging than the lens preform.
