摘要： A rocking seat control apparatus for a moveable seat supported and having a magnetic member attached thereto is provided that is capable of maintaining the seat being rocked constant in rocking amplitude. The apparatus includes a solenoid for bi-directionally attracting the magnetic member to cause the seat to move in a positive and a negative direction alternately and thereby to be rocked; an amplitude measuring means for measuring an amplitude of the seat being rocked and a rocking motion of the seat; an amplitude damping factor measuring means responsive to displacements in the positive and negative directions of the seat being rocked for measuring an extent of damping factor of the amplitude caused while the seat is being rocked; and a solenoid energizing means for energizing the solenoid means during a time period in which the seat is being rock traveling a distance that is a product of the measured rocking swing and the measured extent of damping factor of amplitude. A rocking seat control apparatus is also provided that includes a rocking control circuit that computes a 1/f-type fluctuating rocking motion for driving the solenoid so as to rock the seat in a mode of 1/f-type spectrum fluctuation.

摘要： A non-linear magnetic harmonic motion converter apparatus for transferring non-linear motion into rotational motion for producing work from an interaction of at least two magnetic fields. An axial shaft is disposed in rotating relationship with at least one gimbal supported magnet that reciprocates in relation to the axial shaft. At least one rotor magnet is disposed to rotate in relation to the axial shaft in response to non-linear movement of the at least one gimbal supported magnet. A plurality of rotor magnet units may be proximally disposed to rotate about separate axial shafts, with each rotor magnet unit having a rotor magnetic field influenced by the non-linear movement of the at least one gimbal supported magnet disposed proximal to each rotor magnet unit. Movement of the each gimbal supported magnet creates repulsion and attraction of each respective rotor magnet, with inducement of axial shaft rotation, thereby producing rotational movement that is harnessed to perform work. Also disclosed are combinations of rotor magnet units disposed to rotate about respective axial shafts upon the reciprocation of a central gimbal supported magnet, for utilization in the operation of a fluid transfer pump and/or an electric generator.

摘要： To provide a reciprocation motor capable to detect rotation angle of rotor accurately. Rotor 1 is a magnet having two poles to radial direction and comprises half-cylindrical magnets. Driving coils 5a and 5b are bound equally at coil board 3. Magnetic sensor 7 is fixed at outside and under side of driving coil 5b on coil board 3. Such a construction makes magnetic sensor hard to be influenced by flux generating caused by current flowing through driving coil 5b. Therefore, it is possible to improve position detecting accuracy of rotor 1.

摘要： A voice coil motor capable of quickly and precisely positioning a magnetic head with high precision is provided with a bearing rotatably supporting a head carriage without being influenced by a radial load. Two coils having radial sections contributing to generate a torque are provided to be rotatable in a magnetic space formed by a permanent magnet and a pair of yokes, and are layered along a central rotating axis in such a manner that an extension angle of the radial sections of one coil differs in direction from that of the radial sections of the other coil. When electric current flows, no radial load works, and a resultant force generated in these coils can be a couple of forces in the direction vertical to the movement direction of the magnetic head, so that the magnetic head can be quickly positioned with high precision, realizing a small magnetic disk device.
