    摘要: A process for the preparation of monohydric alcohols by contacting a monoolefin of 2-4 carbon atoms with an aqueous solution containing a heteropoly-acid ion, thereby subjecting the olefin to a hydration reaction, characterized in that said aqueous solution contains the heteropoly-acid ion in a concentration of at least 1/40,000 mol per liter and has a pH ranging from 2.0 to 4.5, and the aqueous solution is heated to a temperature sufficiently high for initiating the hydration reaction, while the free iron ion concentration therein is maintained at not higher than 10 ppm substantially throughout the whole hydration reaction period.

    摘要: 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 the liquid with 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.

    摘要: 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.

    摘要: 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.

    摘要: 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.

    摘要: A power unit suspension system wherein a vehicle frame and a front lower portion of a power unit are connected with each other through a link rotatable about its front and rear pivots. An elastic body is provided between the link and the power unit. Rotational loads due to the power unit weight and rear cushion reaction acting on the link from the power unit side are elastically supported and converted into a moment of rotation.
