Abstract:
A variator assembly comprises a variator of the toroidal-race rolling-traction type using double-acting pistons to control the rollers and differential end load pressure to load the variator, and control means operative to vary the differential end load pressure in sympathy with changes in the net pressure exerted by the roller-control pistons so as to maintain the traction coefficient at the roller disc interface consistently below the limit at which traction would be lost.
Abstract:
An apparatus for absorbing torque vibration comprises inertial bodies comprising first and second flywheels, and a damper mechanism, torque limiting mechanism and hysteresis mechanism interposed between the first and second flywheels.The rotation is transmitted between both flywheels via damper mechanism, torque limiting mechanism and hysteresis mechanism. Resilient members are secured to spring seats, which are engaged with both ends of a spring of the damper mechanism, at an inner-half portion of the spring seat closer to the axis of said flywheels than an axial line of the spring. Excess compression of the resilient members is prevented.

Abstract:
The present invention utilizes a vertically upward force of a water when a tsunami smashes into a building to close openings that exist in an elevated location such as air supply and exhaust ducts, powerlessly and without a manual operation. The present invention serves as a disaster prevention panel which closes an opening 2a disposed in a wall of a building 2. A door bumper 3 is disposed on an outer peripheral wall of the opening 2a, and side door bumpers 4 are disposed on both sides of the door bumper 3. A door body 1, which closes the opening 2a and which has a specific gravity lower than a seawater, is attached between the side door bumpers 4 on both sides so as to freely swing upwards, with a lower portion of the door bumper 3 serving as a fulcrum.
Abstract:
A flywheel device with a torsional damper including a driving side flywheel and a driven side flywheel, a first spring mechanism directly connecting the driving and driven side flywheels, and a second spring mechanism connecting the driving and driven side flywheels via a friction mechanism. The second spring mechanism and the friction mechanism are arranged in series with each other and the series combination of the second mechanism and the friction mechanism is arranged in parallel to the first spring mechanism. The first spring mechanism includes at least one combination of two springs arranged in series with each other. The two springs have a different spring constant or a different maximum angular stroke. Thus, a spring constant of the first spring mechanism changes at a predetermined torsional angle whereby a torque capacity of the flywheel is greatly increased.
