IPC: G02B3/00
Filed: 1990-09-19
Abstract: A color filter or a monochromatic filter (4) used by being pasted on a pickup element (1), having on a transparent substrate (3) at least two resin layers (A), (B) of different refractive indexes which are in contact with each other, an interface at which these resin layers (A), (B) are in contact with each other being formed in a curved state so that the incident light (7) is condensed on each light-receiving portion (2). Accordingly, even when this filter is used in a pasted type solid pickup apparatus, the condensation effect is obtained, and the sensitivity of the apparatus can be improved. The methods of forming an interface, at which the two resin layers (A), (B) are in contact with each other, arcuately so that the interface has a condensation effect include a method of selectively exposing and hardening a photosetting resin so as to form a required curved portion on the surface thereof, and a method of initially forming a projection-carrying stepped element, and then applying a resin to the upper surface of this element under selected application conditions so as to obtain a required convex surface on the projection-carrying stepped element.

Abstract: La présente invention décrit des méthodes et compositions pour isoler les acides nucléiques de cellules. Elle concerne en particulier l'utilisation de compositions chaotropiques, par exemple hydrochlorure de guanidine ou isothiocyanate de ganidium, en association avec des compositions polyanioniques, par exemple contenant des sulfates de polysaccharides (héparine ou sulfate d'héparitine), en vue de l'isolation des acides nucléiques (ARN et ADN). Selon cette méthode, on dissocie et on lyse les cellules à l'aide d'une composition qui libère les acides nucléiques. Cette composition contient un composant chaotropique qui libère les acides nucléiques des cellules (hydrochlorure de guanidine ou isothiocyanate de guanidium). Une fois libérés, les acides nucléiques sont recueillis par précipitation à l'éthanol, puis remis en suspension avant d'être exposés à une composition protéinique de dissociation contenant un polyanion et qui aide les protéines associées à l'acide nucléique à se dissocier desdits acides en suspension. Une fois isolés, les acides nucléiques sont lavés, de nouveau recueillis par précipitation à l'éthanol, puis remis en suspension dans un milieu-tampon sélectif avant leur utilisation.

Abstract: In a traffic system for town traffic in which the cabins are moved on a rail system and are made to circulate, at least for a certain period, by a circulating traction cable, the cabins being fastened to the traction cable with clamps, stations 3 are arranged between the terminal stations 16 with the deflecting devices 1 for the traction cable at arbitrary intervals, in which stations the cabin 12 which is stopping comes to a standstill on a secondary track 6 and the traffic flow has a possibility of overtaking. In the individual stations 3,3' an electronic call system is installed which, in cooperation with the central control, causes the next cabin 12 with a free place to find the stations 3,3' and to pick up the passenger or passengers or to insert a further cabin or cabin train into the rail system. In the cabins themselves station selection devices are provided for the next stop. By virtue of the fact that the secondary track 6 is arranged above or below the through-going rail system 4, the stations are made simpler and it is possible to get directly into the stopping car in a similar manner as in the case of a railway platform. <IMAGE>

Abstract: 2.1 In order to be able to read a display conveniently even if the instrument having the display is in a position unfavourable for the viewer, or if reflections make reading difficult, it has been the practice either for the display to be arranged so that it can be folded out of the instrument housing, or for it to be protected by a cover arranged in a pivoting fashion above the display. In both cases, the folded-out display and the folded-out cover respectively have a disturbing effect. 2.2 The display (13) according to the invention is mounted rotatably about its axis of symmetry, which is perpendicular to the plane of the display. Moreover, a polarisation filter (30) which can rotate about the axis of symmetry of the display can be arranged thereupon. 2.3 An advantageous application of the display is in handsets for radiotelephones or control elements for radio equipment. 3. The drawing shows a perspective view of an instrument housing having a rotatable display and rotatable polarisation filter. <IMAGE>

Abstract: The present invention relates to a method for the fusion splicing of carbon coated optical fibers and to a method for providing reinforced performance of the spliced points. Concretely, carbon coated optical fibers are fusion spliced in an atmosphere containing less than 0.5 vol% of oxygen without the removal of the carbon coating. In order to minimize the amount of damage to the carbon coating resulting from the fusion, the decline in the failure probability of the optical fiber is controlled by means of applying moisture to the spliced part or by means of the adhesion of the oxidized carbon gases to the optical fiber. On the other hand, the carbon coating layer which was removed by oxidation at the time of the fusion splicing is recoated by means of a CVD reaction using a laser as a heat source. By means of this, the decline in the fatigue characteristics of the spliced part can be controlled.

Abstract: A reagent consisting of an HBF4 acid with at least one oxidising agent, preferably hydrogen peroxide, H2O2, added has been found for efficiently decontaminating radioactively contaminated metal components. Ideally, this mixture consisted of a 5%-strength HBF4 acid with 0.5 % by volume of H2O2 added. Radioactively decontaminated lead plates, for example, were removed from this reagent, while the contaminated solution was used as electrolyte without further additions. The contaminated lead or lead oxide deposits at the anode or cathode and can be disposed of as nuclear waste, while the solution can be returned to the process. The process can be performed in exactly the same way using the same reagent if the metal is not lead but copper, nickel, steel, silver or mercury or their alloys. <IMAGE>

Abstract: L'invention se rapporte à un collecteur (10) pour moteurs électriques qui comprend plusieurs segments de collecteur (12) agencés de façon à former un tube cylindrique (14) qui comporte une périphérie externe cylindrique (20) et deux extrémités axiales. Un évidement annulaire (26, 28) est ménagé à proximité adjacente de chaque extrémité (22, 24) du tube, de façon à ce qu'une portion de chaque segment (12) du collecteur forme une partie de la paroi radialement interne de chaque évidement. Au moins deux bagues (34, 36) fabriquées en matériau isolant sont prévues et une ou plusieurs de ces bagues sont ajustées par pression à l'intérieur de chaque évidement, les bagues (34, 36) exerçant ainsi une force dirigée radialement vers l'intérieur sur le segment (12) du collecteur. Les portions d'ancrage des segments (12) du collecteur sont ensuite enrobées d'un matériau électro-isolant durcissable (12), tel que du phénol. Après durcissement et vulcanisation, le phénol fixe les segments (12) du collecteur les uns aux autres. La force dirigée radialement vers l'intérieur qui s'exerce sous l'action des bagues (34, 36) sur les segments (12) du collecteur sert en même temps à stabiliser les segments (12) du collecteur et à empêcher ainsi tout mouvement relatif entre eux pendant les mouvements de rotation à haute vitesse du collecteur (10).

Abstract: L'invention concerne une microlentille (10) cylindrique à grande ouverture numérique (rapide) et à diffraction limitée. Le procédé de fabrication de la microlentille peut être adapté pour former une lentille cylindrique pouvant avoir des surfaces optiques de n'importe quelle forme. La lentille cylindrique (10) peut, par exemple, avoir une forme elliptique ou hyperbolique, conçue pour transformer une répartition de lumière d'entrée en une répartition de lumière de sortie voulue. Selon le procédé, la forme désirée est d'abord donnée à une préforme en verre (20). Ensuite ladite préforme est chauffée jusqu'à ce qu'elle atteigne la température minimum d'étirage et une fibre est étirée à partir de cette préforme. La forme de la fibre, en coupe transversale, dépend directement de la forme de la préforme (20) à partir de laquelle elle est étirée. Pendant l'opération d'étirage, les surfaces (22, 24) deviennent optiquement lisses par polissage naturel à la chaleur. La présente invention trouve de nombreux domaines d'application, par exemple l'optique intégrée, les détecteurs optiques et les diodes laser. La lentille (10) lorsqu'elle est montée sur une barre de diode laser (70) peut fournir une source de grande intensité de rayonnement laser pour le pompage d'un laser à corps solides de puissance moyenne élevée. En optique intégrée, une lentille peut être utilisée pour faire entrer de la lumière dans des ouvertures telles que des guides d'ondes, ou l'en faire sortir. La lentille peut aussi être utilisée pour collecter de la lumière et la focaliser sur un détecteur.
