Abstract: An improved vehicle suspension system capable of providing at all times a desirable maneuvering characteristic variable in response to changes in the angle of steering. The suspension system includes front wheel suspension assemblies for resiliently suspending the front wheels of the vehicle and rear wheel suspension assemblies for resiliently suspending the rear wheels of the vehicle. The front wheel suspension assemblies and/or the rear wheel suspension assemblies have a variable suspension characteristic which is controlled to vary in response to a steering angle exceeding a predetermined level in a manner such that the steering characteristic of the vehicle during steering operation is changed in a direction toward an oversteer characteristic as compared with the steering characteristic during non-steering operation.

Abstract: The fuel injection apparatus includes fuel a fuel metering chamber, an air supply chamber and a further chamber formed in a rigid body. A metering member is slidable within the fuel and gas chambers and passes through the further chamber. The amount of fuel fed to the metering chamber via valve means is controlled by the position of the metering member. An increase in pressure in the air supply chamber opens a valved passage in the metering member and the air expels the fuel from the metering chamber via check valve means. The further chamber collects any leakage of air or fuel past bearing means that receives the metering member.

Abstract: A chain saw safety braking assembly includes a sensing arm pivotally mounted to the housing and having a protrusion. A portion of the sensing arm is located in front of the gripping handle and is arranged to move from a first position to a second position in response to being struck by an appendage of the operator. A flexible brake band is disposed around the peripheral surface of a brake drum, and includes a first end anchored to the housing and a second end coupled to the sensing arm protrusion, such that when the sensing arm moves from the first position to the second position the flexible brake band is moved from a position free of the brake drum to a frictional braking relationship with the brake drum. A latch is rotatably mounted to the housing and is adapted to releasably engage the protrusion on the sensing arm. A spring anchored to the housing cooperates with the latch such that the latch yieldably holds the sensing arm in either the first or the second position.

Abstract: A penetration-through-wall magic set comprising a hollow tube opened at the opposite ends thereof and having formed therein a pair of slots opposite to each other with the tube bore between them, a gimmicked panel including a solid piece as wide as the length of the slots in the tube and having an opening smaller than the tube bore, and a solid pliable piece stuck at one end thereof to the solid piece and overlapping the latter, and an object capable of passing through the opening in the solid piece of the gimmicked panel. The solid pliable piece is extended at the free end thereof over the end of the solid piece so that when the solid piece and solid pliable piece are inserted across the tube from one to another of the slots therein, said over-extending end of the solid pliable piece abuts the inner wall of the tube around the slot so as to be freed from the solid piece.

Abstract: In the four-wheeled vehicle, both the front and rear wheels are turned in response to operation of the steering wheel. The turning angle of the rear wheels is controlled in accordance with a turning angle ratio characteristic curve defined on a .theta.F-.theta.R plane wherein .theta.F and .theta.R respectively represent the turning angles of the front and rear wheels. The turning angle ratio characteristic curve is substantially a broken line having a positive inclination in the region where the value of the front wheel turning angle .theta.F is smaller than a predetermined value and having a smaller inclination in the region where the value of the front wheel turning angle .theta.F is larger than the predetermined value. The turning angle ratio characteristic curve is changed according to the vehicle speed so that the turning angle ratio .theta.R/.theta.F is increased as the vehicle speed increases.

The joints comprise end portions of the glass cloth pieces which are to be joined together, overlapping by at least one joining member, with a thermoplastic resin located between the joining member and the end portions of the glass cloth pieces. The thermoplastic resin bonds the joining member to the end portions, without the necessity for the end portions to overlap one another.

Abstract: An automatic focusing device for a cine camera operates so that the speed at which the lens is moved to its optimum focusing position decreases as a perfect focus is reached. A comparator determines how far out of focus the system is, and a pulse width modulator provides a zero to 100% energization signal to the servo control circuit. The farther the system is out of focus, the larger percentage energization signal from the pulse width modulator and the faster the lens will be moved toward the optimum position.
