摘要： PURPOSE:To steer an axle in turning direction automatically by forming the arrangement of a link trapezoidal in the suspension device capable of sliding a bearing spring and an axle by combining a frame and axle by a link member. CONSTITUTION:The intersection located on the extension line of a trapezoid is made at the fronter part than a rear rear axle 4 by combining a rear front axle 3 by a parallel link and combining the rear rear axle 4 by a trapezoidal link. When a front wheel is steered to the right part at advance time, a cornering force is then generated on the front wheel to direct a frame 1 to the right. The rear rear axle 4 moves until the left side spring stopper 7 is abutted to bearing sprints 9, 10 with changing its direction to the left slightly due to its being combined to a trapezoidal link. The slip angle of each wheel is reduced, an effective cornering force is generated and the rear rear axle is automatically steered in the turning direction.

摘要： PROBLEM TO BE SOLVED: To supply the inertia to the engine by producing eddies in the suction system of the engine and making use of the centrifugal force of the eddies. SOLUTION: A voltex chamber 4 is provided in the suction system of the piston engine, and a guide vane 1 is provided or a suction pipe 2 is mounted eccentrically so as to produce eddies in the chamber. It is thus possible to reduce pumping loss and supply the inertia without being affected by the number of revolutions of the engine.

摘要： PROBLEM TO BE SOLVED: To diminish the inner pressure of an exhaust pipe and exhaust pulsation, and also reduce exhaust loss, and improve an engine output, by arranging a wall at the end of the exhaust pipe, and arranging on the wall a plurality of guide blades expanded in the radial direction. SOLUTION: A wall 2 is arranged at the end of an exhaust pipe 1, and a plurality of guide blades 3 is arranged on the wall 2. Exhaust gas exhausted from the exhaust pipe 1 pulsates, and when pressure is increased by a pulsation, the exhaust gas is exhausted, however, when the pressure is lowered by the pulsation, gas or atmosphere around an exhaust opening is sucked into the inside of the exhaust pipe 1. The exhaust gas and atmosphere sucked at this time, increase their angle speeds by the guide blades 3 and the wall 2, and vortex is generated in an exhaust gas stream. The vortex once generated is further accelerated by Coriolis force so as to be tornadic, and this tornadic vortex makes the inner pressure of the exhaust pipe 1 to lower, therefore exhaust resistance is reduced, and exhaust loss is lowered.
