Abstract: A rolled steel plate 1 wound in a roll shape is unrolled and is cut in given dimensions to form a blank 2. In this case, a cut surface 2a is caused to incline at 1 to 3 degrees relative to the thickness direction of the blank 2, wherein the inclination direction of the cut surfaces 2a, 2a on each side is reversed. The blank 2 cut in this manner is roll-formed to cause the cut surfaces 2a, 2a to confront each other. Since the cut surfaces 2a, 2a on each side incline at 1 to 3 degrees in the opposite direction as described above, the cut surfaces 2a, 2a are caused to be parallel. Then, the confronting sections are laser-welded to form a cylindrical body 3.
Abstract: A manual steering column stamping fixture includes a body member and a linear bearing assembly. The linear bearing assembly is secured to the body member, and includes a marking punch that is driven into engagement with a steering column so as to place an alignment mark on the steering column. Once a center or neutral position of the steering column is located using a checking fixture, the stamping fixture is mounted over the checking fixture using cooperating slots provided by the body member and arms provided by the checking fixture, and such that the marking punch is disposed within the checking fixture and adjacent the steering column. Thereafter, the marking punch is manually moved away from the steering column and against spring bias such that, upon subsequent release of the bearing assembly, the marking punch is driven into the steering column to mark the steering column.
Abstract: The present invention is directed toward an vehicle airbag construction that reduces the incidence of an unrestrained passenger engaging the A-pillar during a high-speed crash. The present invention is also directed toward an airbag structure that reduces the risk of a restrained passenger's hands contacting the instrument panel. In accordance with the present invention, an airbag is formed so as to take on a generally hourglass shape when inflated. Thus, the inflated airbag of the present invention has a greater width dimension at the upper and lower ends thereof than at the middle. The enlarged width dimension at the airbag upper end prevents or minimizes contact between the passenger's head and the vehicle A-pillar. The enlarged width at the airbag lower end prevents or minimizes contact between the passenger's hands and the vehicle instrument panel.

The fuel gas charging port is at least partially covered by bringing the earthing portion into a folded state when the lid is closed, while the earthing portion is brought into a state of being connectable with the earth wire 32 from the folded state and the fuel charging nozzle 31 is brought into a state of being chargeable to the fuel gas charging port when the lid is open.
Abstract: A landing position/orientation of a foot (22) to be landed in a landing action of a robot (1) such as a biped mobile robot or the like is estimated, and a desired footstep path for the robot (1) is set up. Based on the estimated landing position/orientation and the desired footstep path, a future desired landing position/orientation is determined in order to cause actual footsteps of the robot (1) (a sequence of landing positions/orientations of the foot (22)) to approach desired footsteps. Using at least the determined desired landing position/orientation, a desired gait for the robot (1) is determined, and the robot (1) is controlled in operation depending on the desired gait. For determining the desired landing position/orientation, mechanism-dependent limitations of the robot (1) such as an interference between the legs thereof, etc., and limiting conditions of an allowable range in which a desired ZMP can exist are taken into consideration.

Abstract: The present invention provides a method of removing spectator ions and contaminants from aqueous suspensions of solid particles. In accordance with the method of the invention, the solid particles are transported across a phase boundary into a non-polar organic solvent, leaving the spectator ions and contaminants in the aqueous phase. To facilitate the efficient transportation of the solid particles across the phase boundary, the surface of the solid particles is coated with an amphiphilic polyelectrolyte. If desired, the solid particles can be recovered from the organic phase by evaporating the organic solvent.

Abstract: A gait generating system for a mobile robot has n dynamic models and determines a first gait parameter defining a desired gait such that the boundary condition of a gait on a first dynamic model is satisfied. The first gait parameter is corrected step by step by using an m-th dynamic model (m: integer satisfying 2?m?n), which is each dynamic model other than the first dynamic model, and an m-th gait parameter that satisfies the boundary condition on the m-th dynamic model is determined. The m-th gait parameter is determined by correcting an object of an (m?1)th gait parameter to be corrected on the basis of the degree of deviation of the gait generated on the m-th dynamic model by using the (m?1)th gait parameter from the boundary condition. A final determined n-th gait parameter and an n-th dynamic model are used to generate a desired gait.

Abstract: A vehicle tire pressure monitoring system and method is provided, the system including a tire pressure transducer affixed to either the tire or wheel of a vehicle. An electromagnet system is in electrical communication with the tire pressure transducer, the electromagnet system configured to generate pulses and transfer a single bit of data to a sensor system on the vehicle body upon each revolution of the tire or wheel. The sensor system in turn transfers the received bits to an electronic control unit wherein the code is converted into a read out for the vehicle operator. One or more bits within the code may be redundant checking bits or bits representing the status of the pressure transducer or electromagnet system.
