摘要： A magnetic spring has at least two permanent magnets (2 and 4) spaced from each other in a kinetic mechanism. At the time of input and at the time of output, the geometric dimensions between the two permanent magnets are changed by the kinetic mechanism or an external force. The change in geometric dimensions is converted into a repulsive force in the kinetic mechanism, thereby (1) making the repulsive force from a balanced position of the two permanent magnets greater at the time of output than at the time of input, or (2) deriving a damping term of the magnetic spring to provide nonlinear damping and spring characteristics.

摘要： There is provided a bio-signal detector to detect a heart rate and a respiratory rate so that the determination of a kind of a seat load placed on a seat can be made. That is, whether the seat load is a human or an object is determined, and if it is the human, then the physique size is determined to be small or large (the level of the physique size is determined). Accordingly, as compared with the means based only on a weight of the seat load, the determination result is highly reliable. Besides, with the use of the bio-signal detector, the discrimination between the human and the object is ensured. Moreover, a structure additionally including a weight sensor allows the determination of the physique size in more accurate manner.

摘要： The object of the present invention is to provide a vibration damping apparatus having 6 degrees of freedom using a magnetic circuit. Vibration transfer can be isolated by a vibration damping mechanism to set the spring constant utilizing a relative displacement of a movable magnet 37 to a stationary magnet 27 in an axial direction, and an elastic force of a metal spring 50 substantially to be zero. The displacement is quickly restored to an original position by a rubber 24a and the metal spring 50 composing a device to restore the displacement due to vibration not only in an axial direction (Z axis direction) but also in a horizontal direction (X or Y axis direction), in a rotational direction around each axis, or in a twisting direction which is an overlapping direction of these directions and is damped as a vibration in an axial direction. Accordingly, a vibration having 6 degrees of freedom can be controlled with a simple structure.

摘要： The object of the present invention is to improve the production efficiency by making its bonding process unnecessary to simplify the production process. The method of production comprises the step of integrally incorporating a magnetic material when the stationary holders 21 and 22 of the stationary member and the movable holder 31 of the movable member 30 are molded with a non-magnetic material such as a plastic material and the like. Therefore, a magnet unit in which the stationary magnets 23 and 24 or the movable magnet 32 is integrally incorporated into the stationary holders 21 and 22 or the movable holder 31 can be provided only by giving magnetization treatment on the magnetic material without using a bonding process.
