Inventor: DUCHEMIN JEAN-PASCAL
IPC: H01L23/29
Filed: 1980-09-19
Abstract: The object of the invention is to passivate an electronic component of the semiconductor material type, in the case of Ga As, by a semiinsulating layer (4) exhibiting substantially the same coefficient of thermal expansion as Ga As. To this end, the Ga As monocrystalline substrate is subjected to two successive epitaxies, for example in the vapour phase in the same apparatus, in the course of which epitaxies the compounds which are customary in the epitaxial formation of Ga As are caused to act successively to constitute an active layer (3) with an appropriate dopant, and then gaseous compounds capable, with an appropriate dopant, of forming GaxAl1-xAs with x within the range between 0 and 1, or alternatively Ga0.47 In0.53P which are semiinsulators of the same crystalline lattice size as Ga As to constitute the layer (4). Application to diodes and transistors. <IMAGE>

Abstract: The invention relates to a process and an apparatus for manufacturing plastic pipes having a composite structure by extrusion. The material forming the inner and outer walls of the tube is introduced into a special heated and regulated distribution head and is separated into two distinct streams between which a filling material forming a first stream is injected. These three streams are brought together and placed in contact, thus forming a blank which is given its final dimensions by being passed into a conventional tool comprising a trefoil, die and mandrel, followed by a conformator. Application to the manufacture of large dimension tubes for the disposal and drainage of sewage and rainwater.

Abstract: The pawl (5) has a slope (97) on its nose (3) between the short flank (96) and the base (98). It thereby becomes possible, during the coupling of the pawl (5) to the drive shaft (1), to commence the coupling operation before the nose (3) is centrally opposite a corresponding groove (2). The drive shaft is still rotating at this moment. After the hooks (18) have pivoted out, the pawl (5) first strikes against the circumference (108) of the shaft (1) at 106 with the base (98a) rounded according to the circumference of the drive shaft. During the further rotation of the shaft (1), the slope (97) of the nose (3) slides over the rounding (99a) on the shaft (1). In this position, the edge (103) of the nose (3) is already lower than the edge (104) of the groove (2) corresponding to it. A relatively long period of time within the work cycle of the weaving machine is available for coupling, because the coupling can begin even before the shaft (1) is stopped and the nose (3) is centrally opposite the groove (2). Moreover, the coupling operation can be carried out reliably, and influences brought about by machine vibrations remain largely harmless. Also, the coupling parts (1, 5) are protected because edges (99, 104, 103) on the nose (3) and shaft (1) can largely be prevented from being knocked off. <IMAGE>

Abstract: Syntonisateur mecanique de recepteur radio pourvu de circuits d'elimination de l'effet microphonique. Pendant un mode de syntonisation mecanique, la position mecanique d'un element de syntonisation mobile (47 A), fournit une reactance associee reglable qui determine une tension de commande servant a commander la sortie d'un oscillateur commande en tension (VCO) (42) servant d'oscillateur local pour un recepteur radio super heterodyne (10). Apres la selection initiale d'une frequence de canal en reglant la sortie du VCO au moyen de l'element de syntonisation mobile mecaniquement dans le mode de syntonisation, un commutateur (37) deconnecte l'element de syntonisation mobile (47 A) de la commande operationnelle de la frequence de l'oscillateur local et etablit un mode de syntonisation verrouille en envoyant au VCO (42) une tension de commande qui est fonction de la difference entre la frequence du signal de sortie d'un etage melangeur (13) et la frequence centrale d'un etage IF (16) a syntonisation fixe et a bande passante etroite qui suit le melangeur. De preference, cette tension de commande pour le mode de syntonisation a verrouillage est fournie par une boucle d'asservissement de phase (26). Lorsque des changements sensibles dans la reactance determinee par l'element de syntonisation mobile (47 A), le circuit de commutation (37) retablit le mode de syntonisation de maniere que la position de l'element mobile mecaniquement commande de nouveau la sortie de l'oscillateur local. De cette facon, des changements (2) importants dans la position mecanique de l'element de syntonisation mobile pendant le mode de syntonisation a verrouillage n'ont aucun acces sur la syntonisation du recepteur, ce qui permet d'eliminer sensiblement l'effet microphonique.

Abstract: A method of and apparatus for sorting objects by weight uses an electronic weighing device 17 in combination with a conveyor system 10 and discharge devices 34. The objects to be sorted are carried one at a time by containers 6 held in mounting members (13) provided at regular intervals along the conveyor. When each container is brought to the weighing device 17, the container is supported solely by the weighing device, free from the influence of vibration of the conveyor itself, with clearances provided between the mounting member 13 and the container 6. This permits an accurate sorting operation. Furthermore, with an electromagnetic force balance device used as the electronic weighing device, the displacement of a weighing receiver plate 18 of the weighing device may be as little as 0.1 mm, or thereabout, permitting the weighing device quickly to stabilize under load, to allow high speed sorting to be performed.

Abstract: A production runner mold is disclosed which has a movable mold part (302; 402; 502) and a stationary mold part (303; 403; 503) defining a mold cavity (304; 404; 504). Opening on the mold to release a molded product defines a mold opening direction. The stationary mold part is separable into first and second sections (307; 407; 517; 308; 408; 518), the first section including a primary runner (310; 410; 509) and the second section including secondary runners (311; 411; 511). The secondary runners are inclined to the mold opening direction to improve the properties of the molded product. If for some reason the normal production cycle is terminated such that the molten plastic within the inclined secondary runners transfers additional heat to the walls of the inclined secondary runners whereby the molten plastic solidifies throughout its entire cross-sectional region, the normal production cycle may hereafter be re-established by the steps of:
     (h) separating the mold part which contains the inclined secondary runners into its two sections in order to expose the solidified impressions of the inclined secondary runners,   (i) removing the solidified impressions of the inclined secondary runners in such a manner that the impressions of the restriction gate on the solidified impressions of the inclined secondary runners are removed through the inclined secondary runner in a direction which is not parallel to the mold opening direction; and   (j) recombining the two sections of the mold part which contain the inclined secondary runners.
