Abstract: The present invention provides a method and an apparatus for preparing a silicon-containing solid film, which can form a thin film uniformly over a wide area. Raw-material fluid comprising a silane derivative and a hydrocarbon derivative is mixed with carrier fluid comprising carbon dioxide to form a supercritical condition. Further, an active-state is produced in the raw-material fluid of the supercritical fluid by a catalytic reaction with at least one metal catalyst selected from a group consisting of platinum, tungsten, cobalt, nickel, iron or an alloy of each of them. The fluid is blown to the substrate, thereby forming a silicon-containing solid film or a hydrocarbon-containing solid film on the substrate.

Abstract: A rotary damper is provided in a base end of a swing arm forming a part of a vehicle suspension system. The rotary damper comprises a casing defining a fluid chamber having a shape of a fan extending substantially toward a free end of the swing arm in cross section as seen in a plane perpendicular to a longitudinal line of the pivot center line, a central shaft centrally received in the casing, and a single vane extending laterally from the central shaft into the fluid chamber, the fluid chamber being filled with fluid for applying a damping force to the vane as the vane relatively moves in the fluid chamber. By thus eliminating the need for a tubular damper, the space efficiency can be improved, and reduction in the overall size and weight of the system can be improved with the added advantage of allowing avoidance of interference with the drive shaft of the wheel in a simple manner.

Abstract: An all-wheel-steerable vehicle has two front wheels, two rear wheels, and a steering system for steering the front and rear wheels in interlinked relation. The front and rear wheels are steered in the opposite directions to each other, and the steering angle of the front wheels is greater than the steering angle of the rear wheels. The vehicle thereby gives the driver a favorable drive feeling while obtaining a small radius of turning movement of the vehicle.
