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： In a liquid-filled anti-vibration mounting device suitable such as for an engine mount, an accommodation room containing a rubber movable plate is formed inside a partition member partitioning a liquid chamber into a pressure receiving chamber and a balancing chamber. The partition member includes a pair of division walls, one adjoining the pressure receiving chamber and the other adjoining the balancing chamber. Each division wall is formed with a plurality of communication holes. The communication holes are arranged to undulate at least a portion of the movable plate towards the peripheral edge thereof at specified circumferential intervals or greater by the action of the liquid pressure through the communication holes. The movable plate thus deformed, particularly its portion towards the peripheral edge, has a small area to come into contact with the division walls at a time, which effectively disperses and lessens a shock due to contact.

摘要： To allow high speed search for audio files described in a play list and to quickly perform reproduction of the audio files according to the play list even when a plurality of audio files are recorded on a recording medium, a matching comparison unit for performing a search for a file name described in the play list from file names included in a file name list is provided in a signal processing circuit for performing processing such as decoding of an audio file. When reproduction using the play list is instructed, respective file numbers of the audio files detected in the search by the matching comparison unit are output to a control circuit.
