Abstract: This invention presents a method and an apparatus for examining and determining the viscosity of a liquid sealed in a container by applying a centrifugal force to the container, detecting a change in the surface form of said liquid by the means of a sensor, and measuring either a lapse of time from the application of centrifugal force to the time when the output voltage of the sensor reaches a predetermined level or a voltage output of the sensor upon a predetermined lapse of time from the application of a centrifugal force, thereby examining and determining the viscosity of the liquid to find out whether there is any quality change in the liquid without destroying the container.

Abstract: Engines having cylinders of noncircular cross section wherein the cylindrical curve is generated at a preselected constant outwardly normal distance from a closed curve. The closed curve is defined as including two spaced points on a major axis of symmetry of the cylinder with two continuously curved portions extending between these points and curved outwardly from the major axis. The closed curve about which the cylinder curve is generated is preferred such that there is a continuous change of curvature without discontinuity in that curvature in the cylindrical curve. The avoidance of discontinuity in the generating curve aids in mass production considerations and cutter life. A plurality of intake and exhaust port arrangements are disclosed illustrating four intake ports and four exhaust ports on opposite sides of the major axis of symmetry of the defined cylinder. In one embodiment, the outermost of the ports are smaller and are positioned closer to the major axis of symmetry.

Abstract: A piston/crank connection mechanism for an internal combustion engine, including first and second pin members mounted on a piston and a crank of the engine, respectively, a connecting rod member having formed at opposite ends thereof first and second fitting holes in which the first and second pin members are fitted, respectively, and a self-lubricating, heat-resisting, wear-resisting and relatively hard film layer having a slippery surface thereon and interposed between an outer peripheral portion of the first pin member and an inner peripheral portion of the first fitting hole in the connecting rod. The structure eliminates any need for further consideration with respect to lubrication between the pin members and the connecting rod member, provides for reduction in size and weight of an engine, and is advantageous in controlling vibrations and noises.

Abstract: A backlash reducer for a gear transmission system comprises a main gear and an auxiliary gear which form one of a driving gear and a driven gear in mesh therewith of the gear transmission system. The main gear is mounted on a rotary shaft for rotation therewith, and the auxiliary gear is mounted on the rotary shaft for rotation relative thereto. A backlash reducing mechanism is operable in response to a centrifugal force due to rotation of the rotary shaft for angularly moving the main and auxiliary gears relative to each other to reduce a backlash between the driving and driven gears. The backlash reducer may further comprise a mechanism for restraining the backlash reducing action of the backlash reducing mechanism. Alternatively, the backlash reducer may comprise a first mechanism operable in response to the centrifugal force to move the auxiliary gear axially thereof and a second mechanism for converting the axial movement of the auxiliary gear to circumferential movement thereof.

Abstract: A system of lubricated gearing illustrated in the context of a motorcycle transmission. A lubricant vessel is provided to partially enclose the lower portion of the drive gear to deliver additional lubricant thereto. Walls extend radially outwardly adjacent to the drive gear to retain lubricant within the meshing area of the gears, reducing gear noise and impact shock between meshing gear teeth.

The method comprises alternatingly supplying fuel to the engine and suspending the fuel supply to the engine in successive suction strokes. In a heavy load range of operation of the engine, the fuel can be supplied in each of the successive suction strokes. Various different embodiments of the apparatus for performing the above method are disclosed.

Abstract: An exhaust system control apparatus for the exhaust of an internal combustion engine which is particularly useful on two-cycle engines. The exhaust system includes a subsidiary chamber connected to the normal engine exhaust passage with a valve for opening and closing communication between the chamber and exhaust passage to change the pressure wave at the engine cylinder exhaust port to provide optimum performance at high and low speeds. The chamber valve is operated rapidly by a pneumatic actuator supplied with compressed air from one or more of the sources disclosed, namely, a belt driven or electric air compressor and piston and cylinder devices extending between or forming the suspension components of a two wheeled vehicle. A pneumatic valve is operated by engine speed sensing means to supply or release the pressurized air to the actuator at a predetermined engine speed.

The shock absorber is of the hydraulically and pneumatically operated type, is simple in structure, and can be assembled with ease while maintaining a desired degree of performance.

Abstract: A hydraulic shock absorber of the type having a cylinder and a piston with axial passages therethrough. The piston is mounted to slide within the cylinder. Valve plates having orifices therethrough are provided to control flow through the axial passages of the piston. Certain of the valve plates are situated to operate together with a variable effective orifice on the downstream side of the axial passages and to act with a fixed effective orifice as check valve plates when the flow is reversed. The composite valve thus defined offers a smooth and properly sloping velocity-resistance curve. The shock absorber also includes a foot valve assembly controlling flow between the interior of the cylinder and an annular oil reservoir outside the cylinder. The foot valve assembly may have two check valves for controlling flow through two sets of foot valve passages or it may employ a check valve spring which changes from a "V" shape to a flat shape to cover orifices in a check valve plate.
