Title: Piece coulissante en ceramique
Inventor: NISHIOKA TAKAO
IPC: F01L1/16
Filed: 1995-11-13
Granted: 2000-03-14
Abstract: Cette invention a pour objet une pièce coulissante, que l'on forme en combinant un élément de surface coulissant portant une surface coulissante en bombé avec un matériau de base, en particulier une pièce coulissante telle qu'une pièce mécanique de soupape d'un moteur d'automobile, un suiveur de came ou un bras à bascule. Cette pièce coulissante en céramique entrant dans une structure est constituée de la façon suivante: un élément en céramique (1) formant une surface coulissante est combiné avec un matériau de base métallique (2), le taux de bombement de la surface coulissante étant compris entre 0,1 % et non moins de 0,4 % d'une longueur maximum de la surface de joint de l'élément en céramique. Le matériau céramique possède une résistance à la flexion en quatre points, en fonction de la norme JIS R1601, qui n'est pas inférieure à 500 MPa, et l'élément de base métallique comprend essentiellement de l'acier, et de préférence un matériau métallique ayant une texture martensitique au moins dans sa surface externe, ainsi qu'une dureté de H¿RC? > 45. Une telle pièce coulissante en céramique utilise une couche intermédiaire d'un métal ou d'un cermet. La combinaison d'un élément à surface coulissante d'un matériau céramique en bombé et la formation d'un élément de base métallique sont effectuées simultanément, ou alors la surface coulissante de l'élément de base métallique est durcie par chauffage, après qu'elle a été combinée avec l'élément à surface coulissante. On obtient ainsi à faible coût une pièce coulissante ayant un taux de bombement élévé, dans laquelle apparaissent rarement des défectuosités telles que des craquelures.

Title: Brake assurance module
Inventor: MAZUR RICHARD J
IPC: B60T8/58
Filed: 1997-04-24
Granted: 2000-12-12
Abstract: A brake assurance module assures braking on at least one truck.          It includes a summer, a level circuit, a delay circuit, an emergency driver, a valve driver and a timer circuit.   The summer sums friction and dynamic braking signals into a total braking signal.  The level circuit generates a threshold signal when the total braking signal exceeds a threshold.  The delay circuit generates a level signal after having received the threshold signal throughout a preset time.  When the emergency driver receives an emergency signal,  it conveys  a detect signal.   The valve driver controls contacts each in series within a control line used to energize a valve whose operation is normally controlled by the brake control system.  The valve driver when activated closes the contacts thereby permitting the system to control the valves.  When deactivated, the valve driver  opens  them  thereby  preventing  the  system  from controlling the valves.  The timer circuit has set, trigger and reset inputs.  When the set input receives the level and zero speed signals simultaneously, the timer circuit activates the valve driver thereby placing the module in a standby mode.  The timer circuit monitors the trigger input for the detect and full service signals in response to which it becomes enabled.          If  the  reset  input  receives  the  level  signal  within  a predetermined time after the timer circuit enables then the timer circuit resets thereby keeping the module in the standby mode.   Otherwise, the timer circuit deactivates the valve driver thereby placing the module in an intervention mode.

Granted: 2003-02-04
Abstract: L'invention concerne un système de satellite à orbite elliptique utilisé pour la transmission de communication. L'orbite du satellite (100) est moins élevée qu'une orbite géosynchrone. Lorsque le satellite (100) s'approche de l'apogée de son orbite, sa vitesse avoisine la vitesse rotationnelle de la terre et donne l'impression de planer au-dessus de la terre. Chaque station terrienne (104) communique toujours avec un satellite (100) lorsque celui-ci se trouve à une position prédéterminée de son apogée, ce qui donne l'impression à la station terrienne (104) que le satellite (100) plane au-dessus de la terre. Le satellite (100) ne peut donc communiquer avec aucune station terrienne lorsqu'il se trouve en dehors de cette portion d'apogée. Lorsque le satellite (100) se trouve en dehors de cette portion d'apogée, les communications sont donc coupées pour éviter toute interférence avec les satellites géosynchrones. Pendant ce temps, le satellite (100) recharge ses batteries à l'aide de son système d'alimentation en électricité (290). Ce système d'alimentation (290) est d'autant plus petit que le temps d'utilisation du satellite (100) est court.
