Title: Laser printer for continuous webs/labels.
Inventor: MATHEA HANS
IPC: G03G15/20
Filed: 1991-06-04
Abstract: Conventional laser printers for continuous webs/labels have either gentle fixation, are relatively expensive, bulky and difficult to operate and service or are small, compact and robust but damage the printed material by heat and pressure. The profitability of a few larger versions is increased by making repeated use of the strips to be labelled. However, a separating device must be used afterward. The invention indicates a laser printer for continuous webs/labels which is inexpensive, economical to use, does not damage the adhesive layer or printed material and is easy to operate and service. The laser printer has a separating device in the same housing and is extremely compact.

Abstract: Un détecteur de rotation à fibre optique possédant une paire de faisceaux lumineux en contre-propagation dans une boucle comprend un modulateur de phase destiné à moduler les ondes à une première fréquence. Lorsqu'elles quittent la boucle, les ondes se rassemblent pour former un signal d'intensité lumineuse indicateur de la vitesse de rotation et détecté. On déphase en quadrature un signal à la première fréquence par un signal de fréquence inférieure, puis on l'additionne au signal de vitesse détecté. Un amplificateur amplifie les signaux additionnés et provoque également et de manière inhérente des déphasages indésirables et égaux à la fois dans le signal de vitesse détecté et dans le signal en quadrature. On démodule le signal en quadrature et on l'utilise en retour pour réguler la phase d'un déphaseur variable qui produit un signal à la première fréquence dont le déphasage est égal au déphasage indésirable du signal de vitesse détecté, ce dernier signal étant envoyé conjointement avec le signal du déphaseur variable à un démodulateur apte à démoduler les informations de vitesse de rotation à partir du signal de vitesse détecté.

Title: Systeme d'annulation de distorsions en quadrature
Inventor: GIBSON JAMES JOHN
IPC: H03D1/22
Filed: 1991-07-30
Abstract: Des signaux de télévision haute définition ou améliorés comprennent des informations supplémentaires, lesquelles sont modulées à deux bandes latérales en quadrature à l'aide de la porteuse image, et sont passés dans un filtre de Nyquist inverse (222) avant d'être combinés (24) avec un signal vidéo principal modulé par une bande latérale atténuée classique (221). Un récepteur récupérant à la fois le signal vidéo principal et des informations supplémentaires traite le signal vidéo reçu par l'intermédiaire d'un filtre FI (228) présentant une caractéristique de réponse en fréquence de bande latérale atténuée. Deux détecteurs synchrones (230, 232) récupèrent des composantes de signal de phase en phase et en quadrature des signaux de télévision filtrés, ces signaux récupérés comprennent chacun des composantes de distorsion d'interférences en quadrature provenant de l'autre signal. Les interférences passant du signal supplémentaire dans le signal principal sont annulées par filtrage (246) du signal en quadrature récupéré et par addition (244) du résultat au signal en phase récupéré. Ce filtrage égalise également le signal en phase par conversion des composantes de distorsion en quadrature dans le signal en quadrature récupéré en composantes de signal de renforcement dans le signal en phase. On utilise avantageusement ce système de récupération de signal avec un système d'annulation de signal indirect.

Abstract: There is a method of screw-fastening of a drilled-through flat part (7) to a profile carrier 1, in which the profile carrier 1 is provided with a grooved channel 2 which is bounded by two channel walls 4, and in which an attachment screw 9 projects into the grooved channel 2, the shank 11 being screwed into the grooved channel 2 by means of the thread 12, and held. In this case, it is desired for the device to be less costly and to be assembled in a simplified manner. This is achieved in that the channel walls 4 pass through free from any projection as far as the outside 3 of the profile carrier 1, in that their distance from one another is matched to the thickness of the shank 11, and in that the attachment screw is constructed as a sheet-metal self-tapping screw 9 whose thread 12 engages in the channel walls 4. The channel walls take over the function of a mating piece for the sheet-metal self-tapping screw. <IMAGE>

Abstract: The sensor has a plurality of filters (36) and sensor elements (38) for differing spectral ranges of a radiation (18) to be measured. The object of the invention consists in developing a multispectral sensor of this type to the end that it can be manufactured as a discrete component of small dimensions and exhibits a high accuracy of measurement while achieving a high output signal. This object is achieved in that the beam is split, by an optical device (34), into a plurality of partial beams and is reflected onto filters (38). Behind the filters there are disposed radiation-sensitive elements which detect the spectral range corresponding to the transmission range of the respective upstream filter. The remaining spectral range of the partial beam is reflected by the filter surface in a direction towards the other filters. As a result of this, it is achieved that the associated spectral ranges of all the partial beams are passed to each filter.

Abstract: The process for making monolithic multilayer stacks for ferroelectric ceramic actuators involves the application, to foil cards (1, 1') made of a green ceramic composition, of electrically conductive coatings (2) which are circular in shape. They have a radius RB and at their edges (4) each have a part-circular cut-out (3) having a radius RA < RB. The cards (1, 1') provided with coatings are stacked in such a way that the cut-outs (3) of the coatings (2) are offset with respect to one another from card to card, as a result of which two zones form in the stack which do not intersect and in which the coatings (2) and cut-outs (3) alternate in each case. The card stack is laminated. After lamination, channels (7) having a radius RR < RA are punched concentrically to the cut-outs (3), the green composites are then punched from the stack of cards concentrically to the edges (4) of the coatings (2) and with a radius RV, and are fired, with the proviso that the relationship RB > RV >/= (RB - RR) should hold good.   <IMAGE>
