Abstract: An aircraft navigational system for providing a geometic display to the pilot of the vertical position of the aircraft relative to a selected vertical flight path profile as the aircraft progresses between its departure and destination. The vertical profile, which has a climb portion, a cruise portion and a descent portion, is formed by a number of navigational points, each of which is defined by an altitude component and a geographical position component. The profile points which form the climb and descent profiles are calculated from controller assigned altitude and waypoint constraints as well as from airspeed and altitude operating limitations which define various selected aircraft performance climb and descent modes.

Filed: 1987-09-19
Abstract: The invention concerns a process for formation of a high voltage monolithic semiconductor device that contains at least one power transistor formed by emitter (14) base (8) and collector (1, 2) regions, respectively  and an integrated control circuit including collector (13), base (16) and emitter (17) regions, integrated in a single chip. 
     The device is formed by means of a triple epitaxy which utilizes the same doping agent (Phosphorus) and by growth of the third epitaxial layer (6) with a concentration of impurities grea­ter than that in the previous epitaxial layers (5 and 6). By spreading the buried la­yers (4) untill it penetrates inside the third epitaxial la­yer (6), collector regions of transistors in the integrated control circuit are obtained free of unwanted interme­diate layers or phantom layers caused by the out-­diffusion of doping substance present in the heavily do­ped isolation region (10, 11) with conductivity of the opposite type. Finally PN junctions (9812) are formed for the collector-base region of a power transistor and for the isolation zone (11) of the integrated control circuit, capable of withstan­ding high voltages.

Abstract: Reactive stabilizer compounds, to be used in the stabilization of organic polymers, contain a sterically hindered, N-substituted piperidinic, morpholinic or pyrrolidinic group, and at least a hydrolysable silicic function. 
     Such compounds give rise, by hydrolysis of the silicic function, to complex resinous structures endowed with stabilizing properties. 
     The reactive stabilizer compounds can spontaneously hydrolyse inside the polymer, or they can be stably supported on a solid support, or they can be chemically linked to the polymeric chain to be stabilized.

Title: Frein à tambour à réglage automatique
Inventor: CHARBONNIER JACQUES
IPC: F16D65/52
Filed: 1987-12-23
Abstract: Le réglage automatique d'un frein à tambour, lorsque l'usure des garnitures de friction (16) portées par les segments (12) le justifie, est obtenu au moyen d'un levier de réglage (30) monté pivotant sur l'un (12) des segments. Ce levier est en appui sur une entretoise (44) reliant les extrémités des segments entre lesquelles est placé le moteur de frein, lorsque ce moteur n'est pas actionné, de sorte que la position du levier (30) détermine l'écartement au repos entre ces extrémités. Deux surfaces en vis-à-vis (48, 50) formées respectivement sur l'entretoise (44) et sur le levier (30) définissent entre elles un jeu fonctionnel au-delà duquel un réglage est effectué lorsque le frein est actionné. Afin qu'un réglage intempestif ne soit pas réalisé en raison d'un échauffement du tambour, une cale (56) portée par un bilame (52) s'efface de l'espace formé entre les surfaces (48, 50) lorsque la température dépasse un certain seuil, accroissant ainsi le jeu fonctionnel.

Abstract: In the course of each process sequence, the non-statically issued sections (SD) of the main memories (S) of the processors are progressively issued from free sections of the memories in accordance with the respective requirement and are also correspondingly immediately released again following the conclusion of the execution of individual procedures of the process. Compared with a prior issuing of the storage space for the entire process, this reduces the risk of overflow and avoids the necessity of having to dimension the storage space for the extreme case. <IMAGE>

Abstract: In a circular cold saw (1) with a saw blade (6) entering during sawing into the material (5) to be worked from below through a slot (4) in a support plate (3) of a support table (2), the direction of rotation of the saw blade (6) during sawing is selected in such a way that the saw teeth (11) cutting in each case move away from the pivot bearing (7) of the saw-blade arm (8). This results in a position of the resultant of the cutting force at a slight distance, if any, from the pivot bearing (7) so that the feed is considerably relieved of load relative to a reversed direction of rotation of the saw blade (6). <IMAGE>

The actuator (16) then is rotated about its initial fulcrum (50, 52) on the base, and the cable (90) is urged into contact with anti-overstress fulcrums (56) on the base. Continued rotation of the actuator urges the cable (90) into the opposed arms (26, 28) of the contacts (12) to make electrical connection with the arms at (32, 34). Resilient deflectable locking latches (42, 44) on the base (14) engage the actuator (16) and hold the actuator into a fully seated condition.

Abstract: An image forming apparatus has a plurality of image forming stations (1C,1M,1Y,1Bk) capable of forming different images which are to be correctly registered and superimposed. Elimination of possible image misregistration in each image station is executed on the basis of the result of detection of register marks (9C,9M, 9Y, 9Bk, 10C, 10M, 10Y, 10Bk) which are formed by each image forming station (1C, 1M, 1Y, 1Bk). The correction is executed at a timing which is independent from image forming sequences performed by each image forming station in accordance with image signals, e.g., during warming-up of the apparatus after the initial application of the power immediately after the input of image forming operation start instruction through a start key,or after completion of production of a predetermined number of copies counted from the last misregistration correcting operation.
