Patent EP-0396632-A1 (EP)
Title: Closed loop fiber optic gyroscope.
Inventor: BERGH RALPH A
IPC: H01S3/083
Filed: 1989-01-27
Abstract: In a closed loop fiber optic gyroscope, the counter-propagating lightwaves are phase modulated by a triangular wave modulation with the triangular wave skewed to lock the phase difference between the counter-propagating waves alternately to specific values of phase difference which are greater than and less than the phase difference due to rotation. The difference in elapsed time between the up-slope and down-slope portions of the triangular wave modulation yields a measure of rotation angle, whereas such difference in elapsed time divided by total elapsed time yields a measure of rotation rate. The phase difference is further modulated about the locked values at a higher frequency, such higher frequency phase difference modulation being synchronously detected to produce a rotation rate signal component employed to generate the skewed triangular wave. Various other features are employed to light polarization errors.

Abstract: Dans un dispositif servant à réduire à l'aide d'un dispositif tampon (2) les chocs dus à la chute des minerais ou similaire lorsqu'ils sont transférés d'un organe d'alimentation ou d'une cheminée à minerai (S) vers un convoyeur à bande, un ensemble de rainures s'étendant dans le sens de défilement de la bande sont ménagées sur un plateau de support coulissant (3) de la bande (B), afin de réduire aussi bien la zone de contact avec le dos de la bande que la chaleur provoquée par la friction. Un courant d'air s'écoulant dans le sens de défilement de la bande sert au refroidissement, et l'interstice entre la cheminée à minerai et le dispositif de transfert est fermé de sorte qu'un plateau à jupe présentant une faible résistance de friction est supporté de manière à pouvoir tomber sous l'effet de son propre poids, ce qui empêche le matériau à transporter de tomber à l'extérieur de la bande. En outre, du côté retour, la bande se déplace tout en étant courbée selon un angle déterminé de correction par des rouleaux en V inversé, afin d'empêcher le défilement en zigzag de la bande sur la surface de transfert, ce qui prolonge la durée de vie de la bande.

Abstract: Un multiplicateur permet de lier des multiplicandes à m-1 positions avec des multiplicateurs à n-1 positions, représentés par des chiffres binaires. Afin d'obtenir un agencement simple et facile à contrôler du multiplicateur sur une puce, une cellule (SL) est attribuée à chaque position du produit et se compose de circuits-ET (UD) qui forment les produits partiels associés à la position correspondante du produit et de circuits additionneurs (AD) de totalisation des produits partiels pour chaque position du produit. Le nombre de circuits-ET et de circuits additionneurs est le même pour toutes les cellules (SL). Les circuits-ET qui ne sont pas nécessaires dans chaque position du produit pour générer des produits partiels sont mis à zéro. Etant donné que les cellules individuelles ont toutes la même structure, elles peuvent être aisément fabriquées à partir de circuits de base et être aisément agencées les unes à côté des autres. Lorsqu'il devient nécessaire de fabriquer un multiplicateur pour des multiplicandes et des multiplicateurs de plus grande largeur, il suffit d'ajouter d'autres rangées de ces cellules.

IPC: G03B27/73
Filed: 1990-03-29
Abstract: An image frame to be printed is subjected to a three color separation and photometry by using three light receiving devices. In order to cancel a photometry error caused by the sensitivity crosstalk of each light receiving device, the measured light amount of each color is subjected to a matrix calculation. The corrected measured light amount by this matrix calculation is logarithmically converted into a measured density. In order to have a linear relationship between the color correction filter setting position and the measured density, the measured density is converted in a virtual measured density in the linear area. The virtual measured density is corrected by a 3 x 3 matrix calculation to cancel a photometry error caused by unwanted absorption of color correction filters.

Abstract: The present invention relates to an adjustable rear view mirror having a housing (1) and a mirror plate (2) whose angular position with respect to the housing can be adjusted in two planes by means of a drive. The drive takes place by means of two electric motors (8, 9) which are connected via gearing to adjustable gear wheels (20, 21). The adjustable gear wheels have a bore running concentrically with respect to their axis of rotation, in which bores lifting spindles (30) are guided, fixed in terms of rotation. The rotational securing is achieved in that an engagement element (41) engages in a groove of the lifting spindle, which groove runs parallel to its longitudinal axis. <IMAGE>

Abstract: An antenna apparatus to be used in a wireless equipment is which an element part (9) of an external atenna is made of work hardening alloy and even if a large external force is applied to the element part, a removal of this external force causes the antenna to be recovered to its original state. A bending or breaking of the element part are prevented to reduce a deterioration of electrical characteristics of the external antenna. The element part can be bent and stored in a box of the wireless equipment, thereby the box of the wireless equipment can be reduced in size.

Title: A fabric towel dispenser with two abutting towel units.
Inventor: ARABIAN SANDRO
IPC: A47K10/28
Filed: 1990-02-12
Abstract: The fabric towel dispenser advantageously consists of two towel units, each of which is fully operational on its own. Here, the fabric towel (7) is taken over a dispensing roller (20) to an intake roller (25). When the towel (7) is pulled out to form a loop (8) the dispensing roller (20) rotates, as does the intake roller (25) via a belt drive (32). In the intake shaft (30) is fitted a spring (36) which is tensioned when the towel is pulled out. The length of the towel which can be withdrawn is limited by a ratchet (43) and a pawl (44). Since part of the used towel wound on the intake roller (25) can be withdrawn as well, the length of the clean towel to be dispensed can be reduced. After a given time a timer releases the pawl (44) so that the spring causes the intake roller (25) to rotate and wind up the loop (8) of towel fabric.
