Title: Pulse train generating circuit for control of an ozone generating means
Inventor: DUNDER OVE K
IPC: C01B13/11
Filed: 1995-06-06
Abstract: A pulse train generating circuit for accurately controlling the ozone production of an ozone generator, is disclosed. The ozone generator may be an electrode type ozone generator or a laser type ozone generator. The circuit generates a first signal indicative of the target rate of ozone production. A  control signal of a predetermined length first time period having enable and disable portions is then generated. The temporal sum of the enable portions of the control signal within the first time period is representative of the target rate of ozone production. A train of pulses corresponding to the enable portions of the control signal is passed by a pulse train gate, and is fed to the ozone generator so as to cause generation of ozone. The amount of ozone generated during the first time period is directly related to the temporal sum of the pulses in the train of pulses passed by the pulse train gate, so as to thereby provide accurate control of the amount of ozone being generated.

Patent CA-2232202-A1 (CA)
Inventor: HASEGAWA TOSHIYA
IPC: B60G7/00
Filed: 1998-03-16
Abstract: In a wheel suspension system, a trailing link, which connects a knuckle rotatably carrying a wheel to a vehicle body, has a front end which is pivotally attached to a vehicle body via a coupling rod fitted with a rubber bush, an axial center line of the coupling rod is slanted so that a rear end thereof is offset toward a center of the vehicle body, and a rear end which is attached to the vehicle body via a lateral arm made of a plate member so as to be flexible in a fore-and-aft direction. Thus, when the rear wheel is pulled backward as a result of applying a brake, the lateral member made of a plate member deflects and the rubber bush fitted on the coupling rod connecting the front end of the trailing link to the vehicle body deforms in the axial direction. Because the axial line of the coupling rod is slanted in such a manner that the rear end of the axial line is offset toward the center of the vehicle body, as the front end of the trailing link shifts rearward, it shifts toward the center of the vehicle.      Thus, a desired change in the toe-in angle is produced when a brake is applied without compromising the firmness of the steering system.

Title: Systeme de selection d'horloge
Inventor: LUNDH PETER
IPC: H04L7/033
Filed: 1996-09-27
Abstract: Dans un réseau, tel qu'un important centre de commutation de télécommunications, destiné au traitement d'informations dans différentes stations et à la transmission d'informations entre les stations, on a prévu des circuits centraux, lesquels produisent de manière indépendante des signaux d'horloge (CLSY-A, CLSY-B, CLSY-C) qui contiennent à la fois une fréquence d'horloge du système et une fréquence de synchronisation des trames. Ces signaux d'horloge sont transmis par plusieurs lignes de transmission différentes, trois dans le cas préférentiel, à une station où un multiplexeur (63) procède à une sélection d'un signal d'horloge, commandé par des circuits d'évaluation contenant des circuits (9, 11) destinés à déterminer les erreurs dans les signaux d'horloge reçus et contenant aussi un automate fini (69). Le multiplexeur (63) sélectionne constamment, périodiquement et de manière répétée, un nouveau signal d'horloge dans un système cyclique, ce qui est obtenu grâce à des erreurs temporaires très brèves qui sont introduites quand on produit les signaux d'horloge délivrés. Il est certain qu'on introduit ainsi constamment de petits déphasages brusques dans le signal d'horloge sélectionné mais, en même temps, l'amplitude d'un déphasage brusque est réduite par rapport à la position de phase moyenne précédente du signal d'horloge sélectionné quand il est possible que l'un des signaux d'horloge entrants ne puisse plus être sélectionné.

Abstract: A drill bit (6) is equipped with one or more fluid jets (7) that are activated during a portion of the rotational movement of the drill bit (6). A processor (41) located with other down-hole sensors (33-38), is programmed with parameters defining the desired path of the borehole (8). The sensors (33-38) determine the actual spatial location of the drill bit (6) and provide the processor (41) with corresponding information. The processor (41) compares the actual drilling path to the desired path, and if a correction is required, a switching module (3) allows a pressurized drill fluid to be sequentially switched to selected jets (7) during rotation of the drill bit (6) to thereby erode the formation in a direction toward the desired path. With this arrangement, the problems of directional control by surface-located equipment are overcome.
