Patent EP-0227871-A1 (EP)
Inventor: CZARNIAK JEAN-CHRISTOPHE
IPC: H03M1/00
Filed: 1985-12-30
Abstract: A digital-Analog Converter for converting an N-bit digital word into its analog representation including means for splitting the N bits into n sections of N/n bits each. For instance a 12-bit word is split into an odd section and an even section which are processed independently and in parallel. This results in two partial results, V i  and V p  respectively representative of the odd and even bit sections. The last step of the conversion is the action (9) of the two partial results V i  and V p  to provide the analog representation of the 12-bit word. Few operators are required to process each section because each bit is converted sequentially. This provides a low cost, compact and simple converter ; moreover, since few operators are required, it may be advantageous to use high precision operators such as disclosed further on.

Title: Gyroscope a laser en anneau avec vibration aleatoire de miroir
Inventor: STJERN DARYL C
IPC: G01C19/70
Filed: 1985-01-30
Abstract: Gyroscope à laser en anneau utilisant une vibration primaire périodique pour éliminer le blocage aux faibles vitesses de rotation et une vibration secondaire aléatoire pour éliminer le blocage résiduel. La vibration primaire est obtenue à l'aide d'un moteur vibratoire (36) couplé au corps (10) du gyroscope et sensible à un signal de commande à ondes sinusoïdales faisant vibrer le corps du gyroscope selon un mode rotatif. La vibration secondaire est obtenue en faisant vibrer de manière aléatoire deux des miroirs du gyroscope à laser (28, 30) dans une direction perpendiculaire à la face des miroirs et de manière complémentaire pour maintenir constante la longueur du chemin parcouru par les faisceaux.

Abstract: A method of measuring the contact stress in a contact surface (1) between solids of the same or different kinds by utilizing an ultrasonic wave, consisting of the steps of applying a surface wave to the contact surface (1) from the side of one end thereof so as to introduce the surface wave to the side of the other end of the contact surface (1) therethrough, and determining the contact stress on the basis of the sound pressure of this passed wave as an evaluation index, whereby the contact stress in the contact surface between the parts or members of a machine, which are in the static and dynamic state, can be measured non-destructively, easily, quantitatively, and very accurately by a real-time operation without being influenced by the shape, sizes and roughness of a surface to be flaw-detected, contact surface and bottom surface.

Title: Interrupteur a reponse automatique, permettant de limiter le courant
Inventor: REMENYI FERENC
IPC: H01H73/04
Filed: 1985-09-12
Abstract: L'interrupteur possède un ou plusieurs contacts fixes (1, 2) et mobiles (3 et 4) qui entrent en contact mutuellement, par paires, ainsi que deux dispositifs de déclenchement (13, 14) qui agissent sur les contacts mobiles (3, 4), dont le premier coupe automatiquement les contacts lors d'un courant de court-circuit, et le deuxième lors d'une surintensité. De plus, un dispositif d'enclenchement (15) est prévu sur les contacts mobiles (3, 4), et peut être actionné comme on le désire. Dans au moins une paire de contacts (1-4) soit le contact fixe (1, 2), soit le contact mobile est composé d'un matériau de contact, et dans une zone attenante à celui-ci (5), d'un matériau composite ayant des propriétés d'extinction d'arc. Les contacts mobiles (3, 4) fonctionnent de telle manière que la fermeture de l'interrupteur ne puisse avoir lieu qu'au-dessus des zones de couverture des contacts et que le courant ne puisse passer qu'au-dessous de ces zones, qui ne sont pas constituées d'un matériau composite; par contre, l'ouverture s'effectue, dans le cas d'un déclenchement par court-circuit, en raison du fait que l'une des régions (5) composées du matériau d'un premier contact est séparée du deuxième contact (3, 4) d'une paire de contacts.

IPC: B27H1/00

Abstract: A plate featuring a series of profiles (1) or grooves (201) and equipped with locking means (2,226) having support pins (7, 207) designed to accept the hollow post (18) of a series of vices (3,17). The locking means (2, 226) are able to slide, be positioned, locked in place and moved along the profiles (1) or grooves (201), and to support the vices (3,17) by means of the pins (7, 207). 
     By acting upon the manoeuvring screws (10) or threaded rods (210) one is able to set up a line of support pins (7, 207) according to the shape of the structure (5) to be produced, and thus, by inserting the hollow posts (18) of the vices (7, 13) upon the support pins (7, 207) one is able to clamp the materials being worked upon (4) so that they conform to the preset shape. 
     One is able to repeat this operation without limit, the hollow posts (18) of the vices (17) being easily withdrawn such that the product, together with the tightened vices, may be removed from the plate immediately. 
     The plate can be reused for other mouldings, since the support pins (7, 207) can be repositioned by acting upon the mounting means (2, 226). 
     One is able to produce mouldings for curved structures made in sections by setting up a line of support pins (7, 207) for the first section of the design of the moulding to be produced, carrying over the position of the fast two support pins (7, 207) for successive sections, inserting the relevant hollow posts (18) of the vices upon them, and thus obtaining a solution to the problem of continuity. In this way one has a single piece of equipment offering high versatility, being suited to unit or mass production, and for use in either the crafts workshop or in industry, bringing benefits of both a quantitative and qualitative nature.

Abstract: A process for improving the adherence of photoresist materials to inorganic substrate material surfaces. In this process, an organic silicon compound of the general formula <IMAGE> in which R and R<I> denote in each case H, alkyl, cycloalkyl, aryl, halogen-substituted alkyl or aryl, or halogen, and R<II> denotes in each case H, alkyl or aryl, and n is an integer and preferably 1 or 2, is applied to the surface of the substrate material which is then coated with the photoresist. The preferred adhesion promoter is hexamethylcyclotrisilazane, which is far superior to the hexamethyldisilazane hitherto used. The advantages of the process according to the invention are particularly effective in the production of micromechanical structures in which silicon dioxide etching masks have to be produced with a very large layer thickness of a few  mu m.
