Title: Transmitting system for small-sized vehicle
Inventor: INOUE KOJI
IPC: F16H47/06
Filed: 2000-11-09
Abstract: In a transmitting system for a small-sized vehicle in which a crankshaft and an input shaft of a transmission are connected to each other through a fluid transmitting device such as a torque converter. A primary reducing device, the fluid transmitting device and a shifting clutch are disposed on the crankshaft sequentially from one side of a crankcase supporting the crankshaft with a bearing interposed therebetween toward the outside, and the axial movements of the input member, the pump impeller and the turbine impeller on the crankshaft are restrained by the bearing and a nut threadedly fitted at a tip end of the crankshaft. Thus, a creep phenomenon of the fluid transmitting device can be eliminated by controlling the shifting clutch, and the shifting operation of the transmission can be conducted lightly. Moreover, the transmitting system is of a simple construction and improved in assemblability.

Title: Methode et systeme pour prendre en charge plusieurs systemes d'exploitation sur un meme disque et tournant simultanement sur divers ordinateurs
Inventor: MULLEN SHAWN PATRICK
IPC: G06F9/445
Filed: 2001-01-23
Abstract: Méthode et système pour faire tourner, sur différents ordinateurs simultanément, de multiples systèmes d'exploitation à partir de la même ressource de système partagée. On obtient cela, par exemple, en utilisant des réservations de disque élémentaire persistant. Chaque machine lit l'enregistrement d'amorçage maître pour déterminer la partition du système d'exploitation à amorcer. Chaque machine effectue ensuite une réservation persistante d'écriture exclusive élémentaire pour accéder à la partition d'amorçage de système d'exploitation. Ensuite, chaque machine effectue une autre réservation persistante d'écriture exclusive élémentaire pour accéder à la partition du système d'exploitation lui-même. Chaque machine est assignée à une partition de système d'exploitation différente même si elle fait tourner le même système d'exploitation. La clé de réservation unique pour ces réservations est créée à partir d'au moins un ID de processeur, un ID de groupe, un ID de partition de processeur, un ID de complexe d'accès non uniforme à la mémoire, et/ou un ID de noud d'accès non uniforme à la mémoire.

Filed: 1999-05-07
Abstract: In a method for switching between multiple system processors (152, 172) on a  CompactPCI bus (110, 120), when a standby system processor (172, 152) determines a failure affecting an active system processor (152, 172) on the CompactPCI bus (110, 120), the standby system processor (172, 152) places a special arbiter (820) in a one master mode. If the standby system processor (172, 152) determines that a device is at risk of performing a destructive action, the standby system processor (172, 152), quiesces the device. The standby system processor (172, 152) then places the special arbiter (820) in  a multiple master mode.

Inventor: IMINSKI RICHARD J
IPC: F16J1/10
Filed: 2001-11-22
Abstract: A fluid actuator attaches a hinged safety device to a vehicle and pivots the hinged safety device between retracted and extended positions. The housing of the actuator has a base and a removable cover. A sub-assembly is attached to the base. The subassembly includes a generally planar base member with integral right cylinder, lever arm pivot support and stop posts. A piston slides in the right cylinder and forms a fluid chamber between the piston and a closed end of the right cylinder that is fed through a passage through the closed end of the cylinder. A lever arm is pivotally attached to the lever arm pivot support at one end for pivotal movement between retracted and extended positions, the lever arm extending over the cylinder and having a lip at an opposite end that is spaced from the right cylinder. A pivot arm engages the top of the piston at one end and the lever arm at an opposite end to transfer motion from the piston to the lever arm. The lever arm transfers motion to a rotor that is rotationally mounted in the housing for movement between retracted and extended positions. The rotor has a spool at each end and an eccentric arm between the spools at the respective ends of the rotor that engages the lip of the lever arm. A torsion spring encircles each spool with one end engaging the rotor and an opposite end engaging a stop post so that the eccentric arm is biased against the lip of the lever arm and the rotor and the lever arm are biased to their respective retracted positions.
