Patent EP-0400152-A1 (EP)
Inventor: MARUYAMA JUN KAWASAKI FACTORY
IPC: F16K3/34
Filed: 1989-08-16
Abstract: This invention relates to a flow rate control valve device for controlling and supplying a pressure oil flow rate from a pressure oil supply source to a pressure chamber of an actuator such as a hydraulic cylinder of a working machine of construction equipment. The flow rate control valve device includes a main spool (13) inserted slidably into a valve hole bored in a valve main body (10) so as to connect or cut off a main port (11) for controlling a flow rate, which communicates with the pressure chamber of the actuator, with or from a drain port (12) communicating with a tank (25), and equipped with a plurality of notch grooves (23) formed on the peripheral surface of a large diameter portion (14) at one of its ends in an axial direction and a seat (17) formed on one end side; a spring (18) interposed between the deep end surface of the valve hole and one end surface of the main spool and biasing the seat of the main spool to make pressure contact with a seat (19) formed on the valve main body; and a device (20) for pushing the main spool from its other end surface side against the resilient force of the spring in such a manner as to allow the main port to communicate with the drain port through the notch grooves. In this manner, the sliding motion of the main spool (13) can be controlled accurately and finely with high response and high precision flow rate control can be carried out.

Title: Systeme de conservation d'energie pour vehicules sur rail
Inventor: LONG ANDREW MARSDEN
IPC: B61L3/00
Filed: 1989-09-28
Abstract: Grâce au procédé et aux moyens décrits, on peut commander un véhicule voyageant entre deux points fixes soit automatiquement soit en demandant au conducteur d'accélérer, de marcher au débrayé et de freiner lorsqu'il le faut pour respecter un temps d'arrivée prédéterminé au point d'arrêt, permettant ainsi de maximiser chaque période de marche au débrayé. L'emploi de cette méthode maximise l'efficacité de l'utilisation de carburant par le véhicule. L'avance du véhicule est surveillée et est traduite en une courbe vitesse/distance. On détermine les temps de marche au débrayé et de freinage à partir des valeurs connues et de calculs d'approximation relatifs aux caractéristiques de marche au débrayé et de freinage de véhicule le long du parcours restant et ces temps fournissent, en conjonction avec la courbe vitesse/distance en temps réel, des points d'intersection. Ces points représentent les temps de marche au débrayé et de freinage et les moyens indiquant l'action d'une marche au débrayé et d'un freinage sont ensuite actionnés.

Title: Hypodermic needle with protective cover.
Inventor: GLICK MICHAEL A
IPC: A61M5/32
Filed: 1989-10-04
Abstract: A hypodermic needle has a hub that is substantially equal in length to or longer than the length of the needle. A sliding cover, of the order of the length of the extended hub, is sized to make a sliding fit on the hub and to be supported by the hub when it slides. A detent in the inside of the cover engages a groove in the elongated hub that is axial and in the surface of the hub to guide the cover. In the alternative, the detent may be in the hub and the cover may be grooved. The groove has circumferential portions at either end to lock the sliding cover in a closed position to protect the needle point and in an open position to permit use of the needle as a hypodermic. An additional cover is provided which is adapted to engage the hub and envelope the sliding cover and needle.

Abstract: A position sensor (10) is made by assembling a permanent magnet (14), a soft magnetic layer (16) on the magnet (14), a magnetoresistive sensor element (18) on the soft magnetic layer (16), and a toothed ferritic member (20) mounted for movement past the sensor element (18). The permanent magnet (14) is surface-treated to form, in situ, the soft magnetic layer (16) comprising a thin layer of high-permeability, low-coercivity material. An Nd-Fe-B alloy magnet (14) is surface-treated by a laser or electron beam to melt a thin layer (16) which is then cooled to re-solidify into a soft magnetic material. Rapid cooling achieves an amorphous surface layer having the desired properties. Slow cooling results in the formation of alpha-iron grains which enhance the soft magnetic properties. Iron formation is aided by reacting the molten layer with an oxidizing atmosphere. Iron alloying by adding iron powder to the molten layer is also feasible.

Abstract: Selon un procédé de commande des roues arrière de véhicules à moteur en fonction du braquage des roues avant, les angles de braquage des roues avant et arrière sont mécaniquement découplés, un organe de transmission ajuste l'angle de braquage des roues arrière en fonction du braquage des roues avant, les roues arrière sont braquées à court terme de manière réversible en sens contraire aux roues avant, puis sont braquées dans le même sens que les roues avant. L'ajustement des roues arrière est ainsi commandé. Lorsque l'angle de braquage des roues avant est stationnaire et non nul, l'angle de braquage des roues arrière est ramené à zéro après avoir atteint une valeur maximale. On obtient ainsi une amélioration sensible de la dynamique de conduite par rapport à un véhicule classique. En cas d'angle stationnaire, on maîtrise sans problèmes des réactions de modification de charge, l'angle de braquage des roues avant restant inchangé.

Abstract: The present invention relates to rigid connecting elements of the type of a parallel-walled telescope for fastening a removable dental prosthesis to a tooth crown (1) having a buccal veneer (2). A functional surface (5) and a supragingival cervical step (6) are incorporated lingually in the crown (1). Furthermore, a supporting surface (7) is provided on the crown (1) adjacent to the prosthesis saddle. An intracoronal groove (10) which has at least one bend (11) over its length extends through the tooth crown (1), essentially parallel to the lingual functional surface (5) and with a lingual offset relative to the sagittal mid-line (91). Friction grooves (3, 4, 8, 14) are worked in the supporting surface (7), the lingual functional surface (5) and the side wall of the intracoronal groove (10). A step (13) in the region of the intracoronal groove (10) displaces the tilt axis between tooth crown (1) and removable prosthesis part to a site which is optimal in terms of function. Due to the use of a ceramic spacer for shaping of the crown (1) and an exactly fitting connecting element which are factory-produced to high precision, a rigid connecting element is obtained which is particularly suitable for occlusal-gingival spacings of less than 3 mm.
