    摘要: An oscillation limiting mechanism 4 is integrally provided to an engine mount 3 (a vibration proof mount device) of a power plant P mounted on an automobile in a traverse mount fashion. Not only is a stopper metal member 40 in the shape of an inverted U letter disposed so as to cross over a mount body portion 30, but a stopper rubber 42 is formed so that it protrudes from the rear end of a casing of the mount body portion 30 toward the rear side of the vehicle body. Not only is a hollow portion 43 formed in the interior of the stopper rubber 42, but a metal core body 44 is also embedded in the stopper rubber 42 so as to be revolvable around an axis in the vehicle body traverse direction as if it were a link. With such a construction adopted, the stopper rubber 42 is shear-deformed in the vertical direction with comparative ease even in a state where it is brought into contact with the rear side leg portion 40c of a stopper metal member 40 and thereby receives a compressive force in the vehicle body longitudinal direction, and a dynamic spring constant of the mount 3 in the vertical direction does not rise so much even if the stopper acts in rapid acceleration or the like; therefore, enabling increase in surrounding sound in acceleration to be suppressed with a simple structure less of cost up while oscillation of the power plant P is limited in a similar way to that of a torque rod.

    摘要: A first pipe is press-fitted into a second pipe having an inner peripheral surface, circular in section, about an axis of the second pipe. The first pipe, having an outer peripheral surface provided with recesses each located between arcuate portions, and which recesses have the same radius about an axis of the first pipe and are located at a plurality of circumferentially spaced-apart points, The recesses are each located radially inwardly of a phantom circumferential extension of the arcuate portions to extend axially over a predetermined length of the first pipe. Thus, it is possible to relatively enlarge the press-fit margin leading to an elongation limit and to set the dimensional accuracy of the pipe product at a relatively low value by the fact that when the first pipe is press-fitted into the second pipe, the second pipe flows so as to fill a gap produced between the first and second pipes due to the plurality of recesses provided on the outer peripheral surface of the first pipe, as well as by the fact that the first pipe is easy to deform under compression at the recesses.

    摘要: A process for recovering heavy metal ions or heavy metal ions and halogen values from a solution comprising a lower aliphatic monocarboxylic acid, which comprises the steps of:(1) contacting a lower aliphatic carboxylic acid solution containing heavy metal ions or heavy metal ions and halogen values with an anion exchange resin, at least 60% of the ion-exchange groups of said anion exchange resin being in the bromide or chloride state, while the water concentration in the lower aliphatic monocarboxylic acid solution has been adjusted to a level lower than 20% by weight, thereby to adsorb the heavy metal ions or the heavy metal ions and the halogen values on the anion exchange resin; and(2) desorbing the adsorbed heavy metal ions or the adsorbed heavy metal ions and the adsorbed halogen values from the anion exchange resin by elution with an eluent. In the present invention, the halogen values remaining in the lower aliphatic monocarboxylic acid solution which has been contacted with the anion exchange resin can be further recovered by contacting the solution with another anion exchange resin or subjecting the solution to distillation.
