Abstract: A glow discharge etching apparatus includes a magnetic assembly 14,16,18 and 22, for creating a surface magnetic field in close proximity to the walls 30,32 of an etching chamber 12. An electrode 38 is located within the chamber for supporting the object 40 to be etched. A radio frequency signal is applied to the electrode so that it will emit secondary electrons upon bombardment by ions from an etching plasma created within the apparatus. A control plate 34 may be positioned at various locations within the apparatus to regulate the amount of electron leakage to the control plate and thereby regulate the etching process. This apparatus provides improved uniformity and directionality of etching due to a low gas pressure and the surface magnetic field.

Ensuite, pendant l'exécution d'un cycle de moulage par injection normal dans un état de lubrification appropriée, une valeur standard de courant d'entraînement du moteur est déterminée sur la base du courant normal d'entraînement du moteur dans une position spécifique vers laquelle est déplacé un plateau mobile (14), sur lequel a été effectuée une mesure de courant pour l'opération de détermination préalable mentionnée ci-dessus, et sur la base d'une augmentation du courant d'entraînement du moteur, de sorte que la valeur standard et la position spécifique vers laquelle est déplacé le plateau mobile sont stockées dans la mémoire d'un dispositif de commande numérique (50). Le dispositif de commande, en réponse à une instruction d'évaluation du temps d'alimentation en graisse lubrifiante, entraîne une pompe à graisse lubrifiante (40), lorsqu'un courant de moteur détecté dans la position spécifique du déplacement du plateau mobile dépasse la valeur standard. La graisse lubrifiante provenant de la pompe à graisse lubrifiante est distribuée dans chacune des nombreuses parties du dispositif de serrage du moule, selon la quantité requise, par l'intermédiaire d'un distributeur (43).

Abstract: A multiple-stator synchronous induction motor which is started as an ordinary induction motor and then switched into synchronous operation when the rotational speed becomes close to the synchronous speed. The motor includes a plurality of stators (21, 22), an integrated rotor having rectifier circuits (33, 34) and rotor cores provided with rotor conductors (31, 32), static magnetic field generating devices (40) that generate static magnetic fields around the rotor cores, and voltage phase-shifting devices that generate voltage phase differences of 0° and 180° between the voltages induced at the rotor conductors. At the time of start, a circulating current flows between the rotor conductors with the voltage phase difference of 0°, so that the motor starts as an ordinary induction motor. During the steady-state operation, the voltage phase difference is switched to 180° and the static magnetic field generating devices are energized, whereby an alternating voltage induced by the static magnetic field is rectified through rectifying circuits, the direct current flows into the rotor conductors to form magnetic poles on the rotor cores, and the rotational speed is pulled into the synchronous operation owing to the attraction by the above magnetic poles and the rotary magnetic field established by the stators.

Abstract: To transmit analog modulated signals via an optical transmission fibre (such as AM-modulated TV signals via a local optical network), it is important that the noise is minimal. External modulation of the laser signal (a) is therefore preceded by filtering out the noise signal at least in the frequency range of the modulation signal (m), with the result that the modulated signal (c) is free of noise. The occurrence of distortion as a consequence of external modulation by means of, for example, a Mach-Zehnder modulator is compensated for by adding the harmonics normally introduced by such a modulator to the modulation signal in phase opposition. <IMAGE>
